# How a tokenized metals vault settles a purchase and delivery claim A step-by-step breakdown of how a tokenized metals vault works, how a purchase-and-delivery claim moves from trade to physical release, and where onchain payment routing gives every professional in the chain certainty. --- Precious metals have always demanded precision. A 400-troy-ounce London Good Delivery bar is worth well over a million dollars. It sits in a licensed vault, insured, audited, serialized — and around it, a network of professionals — dealers, custodians, brokers, settlement agents, logistics providers — each holding a defined slice of the process together. When the metal moves, or when a token representing it changes hands, every one of those professionals needs to be paid correctly, promptly, and in a sequence that matches their contractual rights. Tokenization does not remove that network. It accelerates the information layer beneath it and, when combined with onchain payment routing, it gives the payment layer the same speed and certainty as the token transfer itself. This article explains how a tokenized metals vault is structured, how a purchase-and-delivery claim unfolds step by step, and what changes — and what stays the same — when settlement runs onchain.

## What a tokenized metals vault actually is RWA vault tokenization wraps a real-world asset, or a pool of them, inside a smart contract structure that issues tradable, blockchain-based tokens representing ownership or a claim on that asset. For precious metals specifically, the model is relatively mature compared with other real-world asset categories. In 2026, the industry standard has shifted toward allocated gold models, where each token corresponds to a specific, serialized gold bar, ensuring the assets are segregated from the issuer's balance sheet. That matters legally. In a bankruptcy proceeding, allocated metal is not part of the custodian's estate — it is recognized as the token holder's property. A common structure is that the physical commodity is deposited with a certified warehouse or depository, which issues a warehouse receipt or storage certificate. That document, evidence of the holder's claim, is then held by a custodian or an SPV. Tokens are then minted against that documented claim. For every fine troy ounce of gold added to the vault, a corresponding token is minted on the blockchain. The result is that the token functions as a digital claim on the asset: it can move at blockchain speed, but its value is anchored to something outside the chain. Holders can trade the token on secondary markets, use it as collateral in certain DeFi protocols, or, under defined conditions, redeem it for physical metal. The platform allows investors to buy, hold, trade, and redeem tokenized gold and silver without handling physical assets, with each token representing a defined gram or ounce of metal, verified through audited proof-of-reserves and real-time price tracking. This token-and-vault structure is the foundation on which every settlement claim in this article rests. ## The parties in a tokenized metals deal Before tracing the mechanics, it helps to name the cast. A full-cycle purchase-and-delivery transaction typically involves: - **The issuer / vault operator** — the entity that ingested the physical metal, had it audited, and minted the tokens. They maintain the legal and custodial relationships with the vault. - **The licensed custodian** — bars are stored in high-security, independent vaults managed by professional custodians such as Brink's or Loomis. The custodian holds the physical metal and releases it against a valid redemption instruction. - **The OTC desk or broker** — the intermediary that found the buyer, priced the metal, and executed the trade. OTC desks covering tokenized gold, including instruments like Tether's XAUT, allow counterparties to settle trades against fiat or stablecoins and access liquidity via multiple connectivity channels. - **The settlement agent** — the professional who coordinates the simultaneous transfer of the token and the payment consideration, ensuring neither leg settles without the other. - **The logistics provider** — when physical delivery is elected, a specialized firm manages insured transport from the vault to the buyer's designated facility. - **The buyer** — institutional in virtually all physical delivery cases. The process suits institutional participants with specific operational requirements and sufficient scale to justify the associated costs and complexity. Each of these parties has a contractual right to a specific portion of the funds moving through the deal. The central settlement challenge is ensuring all of them receive their shares simultaneously, with no float period and no question of sequencing. ## How the claim is structured: token burn, custody release, delivery instruction The mechanics of a physical redemption claim unfold in a defined sequence. Understanding it is essential for any settlement professional who works on tokenized commodity transactions. **Step 1: Redemption request and token burn.** The buyer — holding the requisite number of tokens — submits a redemption request to the issuer's smart contract. The digital tokens are burned on-chain to trigger the documented release of the physical metal from the vault. This burn event is publicly verifiable and creates an immutable timestamp. The token supply decreases; the delivery obligation becomes active. The minimum threshold for physical delivery is material. PAXG holders require at least 430 troy ounces — one London Good Delivery bar — valued at approximately $1.9 million at current gold prices, making direct physical redemption practical only for institutional participants. For silver, thresholds are set by the vault operator but are similarly weighted toward wholesale quantities. **Step 2: Vault operator issues a release instruction.** Upon confirming the on-chain burn, the vault operator instructs the custodian to release the specific serialized bars corresponding to the burned tokens. Custodians issue vault certificates confirming holdings, and gold bars are assigned digital identifiers that trace directly back to the token records — meaning the chain of custody is continuous and documented from mint to release. **Step 3: Delivery mode election.** The buyer has typically elected one of two delivery modes at the time of purchase. Vault-to-vault transfer — in-market delivery without physical movement — is one option. Shipment and delivery, involving transport of bullion to a designated location, is the alternative, though less common in wholesale markets. If physical transport is elected, domestic delivery fees apply even within one jurisdiction, since arranging armored transport from vault to bank or private premises carries substantial fixed charges, and international delivery adds logistics, customs, and insurance surcharges often billed separately from vault insurance. These costs must be pre-agreed, pre-distributed, and contractually locked to the settlement instruction — exactly the kind of complexity that a multi-party payment router is built to handle. **Step 4: Settlement of all payment obligations.** This is where the traditional process shows its seams. The settlement process in precious metal trading involves a coordinated sequence of actions between market infrastructure providers, custodians, and clearing agents, designed to minimize counterparty risk, ensure accuracy, and maintain trust in both physical and derivative markets. In a conventional setup, the broker collects the full purchase consideration and then distributes — sequentially — to the issuer, the custodian for storage adjustment, the logistics provider for transport, and the settlement agent for coordination fees. Each payment is a discrete wire, each carrying its own processing delay, its own confirmation step, and its own reconciliation burden. A confirmed blockchain transfer does not automatically mean the bank payment, client order, fee record, and general ledger are consistent, and without a shared settlement identifier linking order data and transaction hashes, a desk can face duplicate payments, missing entries, or long-lived breaks. The risk is not theoretical. A logistics provider who hasn't confirmed receipt of their transport fee may delay pickup. A custodian whose release fee hasn't cleared may queue the release instruction behind other work. The delivery chain, which appears seamless from the outside, is actually a series of handoffs — each conditional on a prior payment that hasn't yet settled. ## Where onchain payment routing changes the equation The onchain version of the same transaction replaces the sequential payment chain with a single routing event. The buyer sends one payment in stablecoins — say, $1,950,000 USD (approximately AUD 3,000,000 at current exchange) for a 430-ounce gold delivery. That one inbound transaction, routed through shaka.deal, is split instantly and simultaneously to every party at preset shares. The vault operator receives their metal-sale proceeds. The OTC broker receives their dealing spread. The custodian receives the release-processing fee. The logistics provider receives the transport and insurance component. The settlement agent receives their coordination fee. All of this happens in the same block, in the same transaction, with the same finality. **Instant and simultaneous.** The distinction matters. In the sequential model, a payment made at 2:00 PM London time arrives at the logistics provider's bank by the next morning at best — after SWIFT processing, correspondent banking, and internal allocation. In the onchain model, all distributions arrive in the same moment, confirmed in the same block. There is no window in which the custodian has been paid but the logistics provider has not. There is no float period during which one party is carrying the other's credit risk. **Final settlement.** Onchain payment finality is substantively different from bank wire confirmation. An Ethereum transaction that has passed finality cannot be reversed, recalled, or clawed back. This is not a procedural limitation — it is an architectural property of the network. For settlement agents who spend considerable time managing reversal risk, dispute periods, and conditional clearance, this finality is operationally significant. The deal is closed. The distribution is done. **Non-custodial routing.** Shaka.deal never holds funds. The platform routes the inbound payment and distributes to all parties in a single transaction — it is a router, not a bank or an escrow account. The money is in transit for the duration of a single block, then it is at its destinations. There is no counterparty exposure to the routing infrastructure itself. ## A concrete scenario: 500 ounces of silver, three parties, one settlement Abstract mechanics benefit from a worked example. Consider a tokenized silver vault operating on Ethereum. An institutional buyer in Singapore has agreed to purchase 500 troy ounces of LBMA-grade silver — tokenized and held by a Swiss-licensed custodian — from an OTC desk that located the inventory. Physical delivery to a Singapore freeport facility has been elected. The agreed purchase price is $15,500 USD (approximately AUD 23,850) per kilogram equivalent — a round-number proxy for illustration — bringing the gross consideration to roughly $241,000 USD (approximately AUD 370,800). Three parties need to be paid from that consideration: | Party | What it receives | USD | AUD (approx.) | | --- | --- | --- | --- | | Vault operator / issuer | Metal-sale proceeds, net of other obligations | $236,236 | 363,440 | | OTC desk | Dealing fee agreed at 0.4% of gross consideration | $964 | 1,483 | | Logistics and insurance provider | Transport fee for Singapore delivery | $3,800 | 5,845 | In the traditional flow, the buyer wires the full $241,000 to the OTC desk. The OTC desk deducts its dealing fee, then wires the balance to the vault operator. The vault operator deducts the logistics component and instructs payment to the transport provider. The transport provider receives funds, confirms, and schedules pickup. The entire chain takes a minimum of two business days under ideal conditions — longer if any party's bank introduces a delay, if cut-off times are missed, or if a reconciliation discrepancy requires a manual fix. In the onchain model, the buyer sends $241,000 in USDC to the shaka.deal router. The router distributes simultaneously: the vault operator receives their share, the OTC desk receives $964, the logistics provider receives $3,800 — all in one transaction, all in the same block. The vault operator, having received confirmed payment with blockchain finality, can immediately issue the release instruction to the custodian. The logistics provider, having received confirmed payment, can immediately confirm the transport schedule. The entire payment settlement collapses from two business days to one block time. The settlement agent's role in this scenario is not eliminated — it is elevated. They designed the share schedule, prepared the redemption instruction, coordinated the logistics contract, and ensured all parties' wallet addresses were correctly registered. The mechanical distribution work that previously consumed hours of their time — wiring, confirming, reconciling — is handled by the routing transaction. They focus on the judgment work that actually requires their expertise. ## The multi-party payment architecture: how shares are set The preset share structure in a shaka.deal routing transaction is configured before the inbound payment is sent. The settlement agent or deal coordinator defines each recipient's wallet address and their share of the inbound amount — either as a fixed sum or as a percentage of total. Once the deal parameters are set and the buyer sends the payment, distribution is automatic and simultaneous. This structure maps naturally onto the way commodity transactions are legally documented. In a properly drafted metals purchase agreement, every fee, every commission, and every service charge is a line item with a defined obligee. The routing configuration is simply a digital mirror of that legal document. What the contract says each party is owed, the router pays — at the same moment, in the same transaction. For deals with more complex structures — where, say, a silver streaming royalty entitles a fourth party to a small percentage of every delivery-to-this-facility — that royalty stream can be built into the routing configuration as a standing share. Every qualifying transaction routes automatically to the royalty holder without any manual intervention or reconciliation step. Vaults differ from simple point-to-point tokenization because they pool assets, manage yield distribution, and often handle redemption logic automatically. The payment routing layer mirrors this sophistication on the cash side — pooling all payment obligations and distributing them in the same automated, pre-specified, deterministic way that the vault smart contract manages asset distribution. ## What settlement agents and OTC desks gain from routing certainty Settlement professionals working in tokenized metals transactions operate under a particular kind of pressure. The physical asset is real, valuable, and immovable until the paperwork and payments align. Any break in the payment chain — a delayed wire, a misallocated transfer, an unconfirmed logistics fee — creates a hold on physical delivery that has real costs. Storage represents an ongoing expense, and warehouse fees accumulate daily, making extended storage expensive. A deal that settles two days late because a payment chain broke down is a deal that cost the buyer unnecessary storage charges. Onchain routing compresses that exposure to near-zero. When the settlement agent can guarantee to all parties that their payment will arrive at the same moment the delivery instruction is issued — not before, not after, not contingent on a wire clearing — the entire transaction dynamic changes. Parties commit to their obligations with greater confidence. Vault operators release metal more readily when they know payment has finalized. Logistics providers schedule transport with certainty. Blockchain transforms settlement from a delayed, multi-step process into an instantaneous, transparent, and highly efficient component of modern financial markets. For an OTC desk that processes multiple tokenized metal deliveries per month, the administrative saving alone — fewer wires, fewer confirmation chases, fewer reconciliation breaks — compounds into material operational efficiency over a quarter. The reconciliation benefit deserves its own emphasis. All token transactions, ownership records, and audit trails are transparently recorded on the blockchain. The payment routing transaction is equally public, equally timestamped, and equally immutable. A settlement agent who needs to demonstrate to a compliance function exactly who was paid, how much, and when — can do so with a single transaction hash. The blockchain explorer is the audit trail. ## Proof-of-reserves and the payment audit loop One underappreciated synergy between tokenized vaults and onchain payment routing is the way they close the audit loop from both ends. Proof-of-reserves audits provide a point-in-time verification of physical holdings against token supply, with audits occurring monthly for some issuers and quarterly for others. These audits establish that the physical metal corresponds to the token supply — the asset side of the equation. The payment routing transaction establishes the corresponding financial record — who was paid, how much, and when — the liability-and-consideration side of the equation. Together, they provide a complete, auditable, onchain record of a physical delivery event: the asset claim burned, the metal released, and the consideration distributed to all parties, all in a single verifiable chain of events. This is the kind of documentation that compliance teams at institutional buyers, regulatory auditors, and insurance underwriters can work with. It is not a PDF with scanned signatures. It is a cryptographically secured, immutable, publicly verifiable record. ## Allocated vs. unallocated and what it means for settlement design Settlement agents structuring tokenized metal transactions should understand the allocated/unallocated distinction thoroughly, because it determines the legal character of the delivery claim and thus the structure of the settlement instruction. Allocated storage is the most common structure for retail investors, where specific, identified bars or coins are registered under the account holder's name. In an allocated model, the token burn triggers a release of specifically identified bars. The delivery claim is a property claim, not a contractual claim against the issuer. In an unallocated model — less common in high-value institutional tokenized vaults, but present in some structures — the unallocated holding is a general, unsecured claim against the company, and in default scenarios the holder joins the queue of all other unsecured creditors hoping for a recovery from the remaining assets. For settlement design, the allocated model is strongly preferable — it means the buyer's claim survives issuer distress. The payment routing should reflect this clarity. ## Cross-border considerations and stablecoin denomination Tokenized metals transactions are inherently cross-border. A buyer in Singapore, a vault in Switzerland, a logistics provider with contracts in both jurisdictions, an OTC desk registered in London — the payment needs to reach all of them cleanly. The tokens move across borders 24/7, settle in minutes, and are custodied in user wallets rather than brokerage accounts. The payment layer, when routed onchain in a major stablecoin denominated in USD, shares these properties. There is no SWIFT correspondent chain. There is no cut-off time that causes a wire to queue overnight. There is no FX conversion risk for parties receiving USD stablecoins, because the denomination was agreed at trade time and is fixed in the routing configuration. Unlike traditional gold transactions that often involve days of clearing time, gold token transfers settle in minutes thanks to blockchain finality. When the payment layer matches this speed, the full transaction — token burn, payment distribution, vault release instruction, logistics scheduling — can complete in a single coordinated cycle rather than a drawn-out series of confirmations. For settlement agents working in this space, the implication is significant: a cross-border tokenized metals delivery that previously required two to three business days of payment coordination can be settled within a single business session. The professional work — designing the deal, preparing the documentation, managing the parties, ensuring contractual compliance — remains. The mechanical latency does not. ## Bringing it together: the settlement agent as routing architect The practical question for any settlement professional entering the tokenized metals space is: how does my role change? The answer is that the substance of the role deepens even as the administrative burden decreases. Configuring a multi-party routing transaction requires exactly the same commercial and legal analysis as drafting a settlement waterfall — who is owed what, in what order of priority, conditional on what events. The routing configuration is the executable form of that analysis. Getting it right demands professional judgment. What disappears is the manual execution overhead: sending individual wires, chasing confirmations, reconciling mismatches, managing float. The routing handles that. What remains — and what becomes more valuable — is the expertise to structure the deal correctly, anticipate edge cases (a logistics provider who fails to confirm, a delivery address that changes before transport), and ensure the token burn and the payment are correctly coordinated. Shaka.deal provides the routing infrastructure — one incoming payment, preset shares, simultaneous distribution, final settlement — on Ethereum. The settlement agent provides the judgment that makes the routing configuration correct and legally sound. These are complementary functions, not competing ones. By leveraging blockchain's ability to record and verify transactions in real time, institutions can achieve atomic settlement. Institutional platforms use smart contracts to automate post-trade processes and collateral movements. The routing layer is the final piece that brings the payment side of the transaction to the same standard of automation and certainty that the asset-transfer side has already achieved. ## Conclusion: the vault settles, the payment must match it A tokenized metals vault is, at its core, a precision instrument. Institutional appetite is growing fast, driven by faster settlement, fractional ownership, and 24/7 liquidity that legacy custody rails can't match. The asset side of these transactions is already operating with the speed and certainty that blockchain infrastructure enables. The tokenized gold market exceeded $6 billion in market capitalization by early 2026, driven by institutional demand for fractional, liquid exposure to physical bullion. The payment side — the distribution of consideration to every professional, every custodian, every logistics provider — needs to match that standard. Sequential wire chains, manual reconciliation, and multi-day float periods are mismatched to a settlement infrastructure where the token burns in one block and the vault release instruction should follow immediately. A purchase-and-delivery claim on a tokenized metals vault can be fully settled — token burned, metal released, all parties paid, all records immutably documented — in the time it takes a single Ethereum transaction to reach finality. The vault has done its part. The payment routing needs to do the same. That is what shaka.deal is built for: one inbound payment, every party's share distributed simultaneously, the deal closed with certainty. In a tokenized metals transaction, that is not a convenience — it is the settlement standard the asset class demands.
