# Can you do an OTC trade without a trusted middleman

How two parties can settle a large trade with certainty when they don't know each other, and what replaces relying on trust.

## Can you do an OTC trade without a trusted middleman
The question sounds abstract until you're staring at a nine-figure block trade with a counterparty you've spoken to exactly twice. One of you has to move first. The other one could disappear. No exchange is backstopping this. The entire arrangement rests on a chain of promises between people who may never meet in person — and that chain is only as strong as its weakest link. Whether two parties can close that trade with structural certainty, rather than with fingers crossed, is one of the most practically important questions in professional OTC markets. This article answers it honestly, including when the answer is yes and when it isn't.

## What "trusted middleman" actually means in OTC

Before testing whether you can operate without one, it's worth being precise about what the middleman is actually doing. In a traditional OTC deal, trust is not a single thing — it is layered across several distinct functions.

Counterparty risk is one of the biggest hurdles in OTC trading. Unlike centralized exchanges that rely on automated safeguards and standardized procedures, OTC markets operate on a bilateral basis — each deal hinges on the reliability of the counterparty. The trusted middleman can be performing any combination of these roles: finding the other side of the trade, confirming identity and regulatory standing, holding assets during the settlement window, guaranteeing delivery, or simply lending their name as moral surety that both parties behave.

Some desks act mainly as brokers — they connect the client with liquidity and coordinate the deal, but are not necessarily the direct counterparty. Others operate on a principal basis, meaning they may trade from their own book. The distinction matters enormously when you ask whether a trusted middleman is strictly necessary. A principal desk that takes the other side of your trade is not a neutral intermediary; it is your counterparty. A brokered desk that simply matches you with another end-user and coordinates settlement is playing a different role entirely — one that is at least partially separable from the trade itself.

OTC trading is the direct exchange of financial assets between two parties outside of centralised exchanges. They negotiate terms themselves, often through a broker or dealer, and settle the deal off the public order book. No standardised contract, no auction — the parties agree on what fits the mandate. This is the core of the problem: without an exchange's automated matching and clearing engine, *something* has to coordinate the two sides. The question is not whether coordination is needed, but what form it has to take.

## The four settlement models and their trust requirements

There are essentially four ways to settle an OTC trade between strangers, and each carries a different level of residual trust requirement.

### Bilateral settlement

The oldest and riskiest model is simple bilateral settlement. One side wires fiat, the other side transfers crypto. There is no escrow, no custodian, no atomic guarantee. Somebody goes first, and the other party either performs or doesn't. This is how deals were done when counterparties had long-standing relationships and reputations to protect. Between strangers, it is not a settlement method — it is a gamble. The full principal value of the trade sits at risk from the moment one leg moves until the other confirms.

This could mean not delivering the cryptocurrency as promised, failing to make the agreed fiat payment, or even becoming insolvent before the trade is completed. Unlike centralized exchanges, OTC trades are direct agreements between two parties, without a central authority to ensure settlement. In practice, bilateral settlement between strangers works only when the amounts are small enough that either party can absorb a loss, or when the reputational and legal exposure of default is so severe that rational actors don't walk away. Neither condition holds reliably at scale.

### Custodian-based DVP

The dominant institutional model today deploys a qualified custodian as a settlement agent in a delivery-versus-payment structure. Most modern crypto OTC trades settle via a qualified custodian acting as the neutral settlement agent. Both sides deposit their assets to the custodian, the custodian verifies both legs are present, and then releases them simultaneously in a delivery-versus-payment swap.

This model largely solves the problem of who moves first. Neither party moves their assets to the other party directly — both move to the custodian, who validates simultaneous receipt and then releases. The residual trust requirement shifts from the counterparty to the custodian itself. Despite its advantages, OTC trading involves risks, particularly related to counterparty exposure and regulatory complexity. Because transactions occur outside centralized clearing systems, participants must rely on the credibility and controls of the OTC provider.

The cost of this model is complexity, speed, and accessibility. Fiat leg settlement can take from two to five business days, depending on the type of withdrawal and bank infrastructure. An OTC desk that features same-day settlement offers a significantly compressed end-to-end timeline compared to many standard workflows, which may involve waiting a few days before you can use your funds. The custodian also has onboarding requirements, minimum trade sizes, and operational hours that may not align with the deal. For very large, well-planned institutional trades, this is the standard and it works well. For faster-moving transactions between parties who have not pre-established custodial relationships, it introduces friction that can exceed the friction it was designed to eliminate.

### Atomic on-chain settlement

The ideal settlement model is atomic, meaning both legs of the trade happen in the same transaction or not at all. On-chain atomic swaps using hash time-locked contracts (HTLCs) or modern protocols allow two parties to exchange assets across different blockchains without any trust assumption. The buyer's payment and the seller's delivery are mathematically bound together. If either side fails, both legs revert. This is the cleanest possible settlement and removes counterparty risk entirely.

This is the honest answer to the core question: yes, you can do an OTC trade between strangers with zero reliance on the trustworthiness of the other party, provided both legs are onchain and the settlement mechanism is atomic. Neither party is trusting the other — they are trusting the math.

The catch is that atomic on-chain settlement is slow and gas-expensive, so it is mostly used for very large institutional trades where the cost is worth the safety. There is also a harder constraint: atomic settlement between two blockchain assets is achievable, but as soon as one leg of the trade is fiat — a wire transfer, a bank payment, a stablecoin that requires off-chain redemption — the atomic guarantee breaks down at the fiat boundary. The risk that the issuer of a tokenized asset will be unwilling or unable to honor redemption promises mirrors traditional counterparty credit risk, but it arises even when the on-chain leg of the transaction is flawless. Even the best onchain settlement cannot make a bank wire atomic with a token transfer.

### Onchain settlement with stablecoins

The practical convergence point for many professional OTC trades today is settling both legs onchain using stablecoins as the payment medium. Transactions settled on-chain can offer faster and more predictable finality compared to traditional financial infrastructure, as they are not constrained by banking hours or correspondent networks. On-chain settlement additionally provides verifiable transaction records, supporting reconciliation and audit processes.

When combined with stablecoins, blockchain settlement can further enhance liquidity management and reduce settlement risk in cross-border transactions. This is not fully trustless in the philosophical sense — stablecoin issuers introduce their own counterparty risk layer — but for practical purposes, a USDC-settled OTC trade between two wallets that both pre-fund and close atomically is considerably more certain than any arrangement involving wire transfers and phone calls.

## Where the trust problem actually lives

The settlement layer is not always where trades fail. Experienced OTC professionals know that the trust problem often surfaces earlier, in the negotiation and confirmation phase.

The first concern is counterparty reliability. If the provider is weak, poorly structured, or unclear in its process, the client takes on unnecessary risk. In large transactions, trust is not a marketing word.

Before settlement has even been arranged, the two parties must agree on price, size, asset, settlement timeline, and documentation. Parties agree on price method (fixed, formula, VWAP), notional, settlement currency, collateral, and dates. For derivatives, you can set strike conventions, day-count, and custom maturities; for spot and forwards, you can bundle legs or route allocations per account. Each one of these terms is a negotiation, and each creates a window during which the other party can re-trade, extract information, or simply walk away. No onchain mechanism eliminates the negotiation-phase risk unless the deal is structured entirely as a smart contract with terms locked before either party commits.

This risk becomes even greater with large, customized transactions since settlements are often manual, legal recourse can be murky, and there's no central clearinghouse to step in if something goes wrong. The scale of the transaction amplifies every vulnerability. A $500,000 trade between two reasonably known counterparties is one thing. A $50 million block trade between a seller who sourced the asset privately and a buyer who has not previously transacted with them is another entirely.

## When you cannot settle without a trusted intermediary

The honest answer to the headline question is conditional. For a purely onchain-to-onchain swap — two digital assets, two wallets, an atomic settlement protocol, no fiat leg — structural certainty is achievable without any human intermediary standing in the middle. The protocol replaces the person.

But most professional OTC trades are not like this. They involve at least one fiat leg. Parties negotiate OTC trades directly, streamlining the settlement process and finalizing transactions more quickly. Fiat leg settlement can take from two to five business days, depending on the type of withdrawal and bank infrastructure. During that window, the crypto side has often already moved. Somebody has already taken the exposure.

The realities of OTC trading often expose fiat settlement's limitations. Banking cut-off times, cross-border transfer delays, and intermediary fees can slow down settlement, sometimes by days. When markets move quickly, these delays can translate into missed opportunities, idle capital, or increased counterparty risk.

There is also a compliance dimension. Another risk area is regulatory and banking compatibility. When fiat enters the picture, sloppy compliance can quickly become a serious problem. A provider that treats verification casually may create settlement difficulties later. A trade that settles without friction on the asset side can still create serious problems if the counterparty's fiat leg triggers correspondent banking flags, AML review, or jurisdictional issues post-close. The result is settlement that appeared final but is functionally frozen in a bank's review queue.

And then there is the question of who the counterparties actually are. In theory, trustless trade settlement allows for secure and transparent trading where players don't need to rely on trust in the other party. However, this kind of trade settlement presents its own challenges. OTC trading occurs directly between parties, making it challenging to verify the identity and legitimacy of the other party. Structural certainty about payment mechanics does not eliminate the risk of trading with a party whose assets are encumbered, whose representations about the asset are false, or whose subsequent regulatory status causes the trade to unwind.

## How professional advisors and brokers manage these gaps

The persistent need for a trusted intermediary is not a failure of technology. It reflects the reality that most OTC trades combine elements that are not yet fully reducible to a single atomic transaction. The professional who brokers the deal — whether as a dealer, agent, advisor, or closing specialist — is doing something the protocol cannot yet do: performing diligence on both sides, confirming that representations match reality, coordinating across different settlement rails, and creating a documented paper trail that holds up under regulatory scrutiny.

An intermediary plays a significant role when you're moving a lot of crypto. They're not just a middleman — they're more like a facilitator and a risk manager. Their main job is to connect parties with someone who wants to do the opposite trade. They have access to a wider network of buyers and sellers than you might find on your own, which is key for big trades.

Good OTC service brings direct communication into the process. For a complex transaction, that can be extremely valuable. The ability to speak with a real person, clarify conditions, and move through the trade step by step reduces uncertainty.

There is also a practical reality about scale. Risk management strategies for mitigation include due diligence upfront — requesting audited financials, proof of reserves, and regulatory credentials before committing to large trades — as well as credit limits per counterparty, phased settlement, and reputation verification through industry networks and past client references. Each of these steps requires someone to execute them. The broker or advisor who coordinates a $30 million OTC trade is not just introducing two parties and collecting a fee — they are running a structured risk-mitigation process in parallel with the deal itself.

Where deals involve multiple parties receiving proceeds — when a block trade closes and multiple advisors, co-brokers, or deal participants each have a claim on the payment — the coordination challenge compounds. Without a structured disbursement mechanism, someone receives the full payment and is then trusted to route portions out to others. That is a new counterparty risk introduced at the closing moment, not eliminated. When the deal is structured onchain with a payment router that splits proceeds automatically to each wallet in one transaction, that final moment of trust disappears. Shaka handles exactly this: the professional structures how the money lands across all participants when the trade closes, and it does so as a single, final onchain transaction. No one waits for someone else to wire them their share.

## The scenarios where structural settlement is realistic today

The gap between what is theoretically possible and what is practically achievable in real OTC deals is narrowing, but it is not closed. Here is a clear-eyed read of where structural settlement without relying on counterparty trust is genuinely available today.

**Crypto-to-crypto block trades at scale.** On-chain atomic swaps allow two parties to exchange assets across different blockchains without any trust assumption. The buyer's payment and the seller's delivery are mathematically bound together. If either side fails, both legs revert. For a trade between, say, $20 million in BTC against $20 million in USDT, where both parties hold assets onchain and the settlement protocol supports atomic execution, structural certainty is genuinely available. The gas cost is real but immaterial relative to the deal size.

**Stablecoin-settled OTC deals with onchain wallets.** Where both the buyer and seller are willing to denominate the trade in a major onchain stablecoin, a well-designed payment routing mechanism can execute the transfer atomically without a human settlement agent holding funds in between. Both parties pre-confirm addresses, the trade closes, and both wallets receive their respective assets simultaneously. On-chain settlement provides faster and more predictable finality compared to traditional financial infrastructure, as it is not constrained by banking hours or correspondent networks.

**Multi-party disbursement on close.** This is the scenario that most often creates friction in well-structured deals: the trade itself closes cleanly, but the proceeds then need to fragment across advisors, co-brokers, and deal participants. Without structural tooling, this is handled by one party wiring others, which creates sequential trust dependencies — each recipient is trusting whoever received the primary payment to forward their share. An onchain payment router resolves this entirely.

**Where structural settlement breaks down.** Fiat settlement offers a sense of certainty — funds move through regulated banks, accounting treatment is straightforward, and compliance teams are comfortable with the process. For many businesses, this remains an important foundation. But the moment fiat banking rails enter the settlement sequence, the atomic guarantee is broken. No onchain mechanism can make a SWIFT wire and a blockchain transfer happen simultaneously. Deals that require fiat settlement on either leg will continue to require either pre-established trust between the parties, a custodian in the middle, or a structured sequence with one side accepting interim exposure.

## The practical framework for evaluating a specific trade

When you're sitting across a deal where the counterparty is unfamiliar, the framework for deciding how to structure settlement comes down to three questions.

First: are both legs of the trade settleable onchain? If yes, atomic settlement is achievable and structural certainty is within reach. If either leg requires a bank wire, you need to determine which side carries the interim exposure, for how long, and whether a custodial arrangement can compress or eliminate that window.

Second: how much do you know about the counterparty's compliance and operational standing? In OTC crypto, price and size mean nothing if the counterparty fails to deliver. A counterparty with shaky finances or unclear operational practices can turn a seemingly great deal into a costly default or drawn-out dispute. To protect yourself, take steps like verifying their identity and regulatory standing, checking their track record, and understanding their custody and settlement processes. Settlement certainty on the rails is not the same as deal certainty. You can close atomically with a counterparty whose assets are legally encumbered and still end up in a dispute.

Third: how are proceeds structured on your side? If you have co-advisors, referral partners, or multiple deal participants who are owed shares of the payment, your settlement infrastructure needs to accommodate that from the start, not as an afterthought after the primary close. That disbursement sequence is itself a trust chain — and the cleaner it is structured before the deal closes, the more professional and certain the entire process becomes.

## The honest answer

You can do an OTC trade without relying on the trustworthiness of the other party — but only under specific structural conditions. Both legs need to be onchain, the settlement protocol needs to be atomic, and the representations about the assets need to have been verified before the mechanics execute. When those conditions are met, structural certainty genuinely replaces personal trust.

Most professional OTC trades do not currently meet all three conditions simultaneously. One leg is often fiat. The counterparty's compliance standing matters beyond just the mechanics of the transfer. The deal involves enough participants on the receiving side that disbursement itself becomes a settlement problem. These gaps are not permanent — the infrastructure is closing them faster than most people in the market appreciate — but the professional who pretends they don't exist is not actually protecting their clients.

What has changed, and what will continue to change, is the surface area of the trade that requires trust. Atomic settlement reduces the trust requirement during the transfer moment. Onchain payment routers eliminate the trust requirement in disbursement. Structured compliance processes front-load the verification work so it doesn't become a settlement dispute after the fact. The question is no longer whether trustless OTC settlement is possible in the abstract — it is which pieces of your specific deal can be made structurally certain, and what that precision does to your exposure when something unexpected happens.
