# What a wrapped token is and whether to accept one as payment A clear explanation of how wrapped tokens work, the risks they carry, and the practical framework professionals need before accepting one as payment in a deal. --- A counterparty wants to close a deal and they are offering to pay in WBTC, or WETH, or some other token whose ticker starts with a "W." If you have handled onchain payments before, the name looks close enough to familiar assets that it feels safe. If you are newer to onchain settlement, the ticker might look confusing entirely. Either way, the question is the same: is this thing actually worth what it says it is, can it be turned into something you can use, and will a payment routing tool like shaka.deal process it cleanly across all parties at once? This article answers those questions from first principles. It explains what wrapped tokens are mechanically, why they exist, how the peg between a wrapped token and its underlying asset is maintained — and where it can break. Then it walks through the professional due-diligence checklist for anyone in a deal role — closing attorney, settlement agent, OTC desk, escrow officer, broker — who is considering accepting a wrapped token as incoming payment.

## Why wrapped tokens exist in the first place To understand a wrapped token, start with the underlying problem it solves. Blockchains are separate systems that cannot communicate easily with each other. You cannot use Bitcoin directly on the Ethereum blockchain, because only the Bitcoin blockchain "knows" that you hold Bitcoin. Wrapped tokens were created as a solution to this problem. Because blockchains have distinct architectures and consensus mechanisms, they cannot natively communicate or exchange value. A user holding Bitcoin, for example, cannot directly deposit it into an Ethereum-based lending protocol. Wrapped tokens bridge this gap by creating an ERC-20 compatible version of Bitcoin that can interact with Ethereum smart contracts. The analogy that captures this well comes from the token's name itself. The "wrapping" terminology comes from the process itself — the original asset gets "wrapped" in a new token standard compatible with the target blockchain, much like wrapping a gift in different paper that makes it suitable for a new occasion while the contents remain unchanged. The concept addresses a critical limitation in cryptocurrency: most digital assets operate exclusively on their native blockchains and cannot directly interact with other networks. Bitcoin exists on the Bitcoin blockchain, Ethereum operates on its own network, and thousands of other cryptocurrencies each inhabit separate ecosystems. This isolation prevents these valuable assets from accessing features, applications, and opportunities available on other blockchains. ## How the wrapping mechanism works Wrapped tokens are created and destroyed by a process called "minting" and "burning." To mint a wrapped token such as WBTC, the underlying asset — in this case BTC — is sent to a custodian who stores the BTC in a digital vault. Once the underlying BTC has been locked away, an equivalent amount of WBTC can be minted. This process can also be understood as "wrapping." The underlying asset is "wrapped up" in a digital vault using a smart contract, and a newly wrapped asset is minted for use on another blockchain. The original asset gets locked in reserve — held by a custodian or a smart contract — while an equivalent amount of wrapped tokens is issued on the target chain. The peg is maintained 1:1: if 1,000 WBTC exist in circulation, exactly 1,000 BTC must sit in reserve backing them. Redemption is simply the reverse. Wrapped tokens can be redeemed for native tokens through the unwrapping or burning process. Users send wrapped tokens to the protocol custodian or smart contract, which destroys the wrapped tokens and releases equivalent native assets back to the user. There are two main structural variants of this model: The lock-and-mint model is the standard: a custodian or program locks the original token, while a wrapped version is minted on another chain. Redemption reverses the process — the wrapped token is burned, and the original is released. This is how Wrapped Bitcoin (WBTC) works on the Ethereum blockchain. In contrast, the burn-and-release model destroys tokens on one chain before unlocking them on another. Both approaches solve the same problem but have different models of trust: one relies on custodians, the other on bridge protocols. ## The major wrapped tokens you will encounter **WBTC — Wrapped Bitcoin** Wrapped Bitcoin is among the most prominent wrapped tokens; it permits BTC holders to utilize their holdings on DeFi platforms and in Ethereum's decentralized applications. WBTC holds roughly $8.8 billion in locked BTC as of April 2026, making it the largest wrapped token by TVL and one of the most significant components of DeFi. **WETH — Wrapped Ether** WETH is a slightly different case, and understanding it matters because it is one of the most common tokens circulating on Ethereum-based payment flows. Wrapped ETH is a smart contract that lets you deposit any amount of ETH into the contract and receive the same amount in minted WETH that conforms to the ERC-20 token standard. WETH is a representation of ETH that allows you to interact with it as an ERC-20 token, not as the native asset ETH. Why does this distinction exist inside the same blockchain? ETH predates the ERC-20 standard, so ETH doesn't conform to this specification. This means you can't easily exchange ETH for other ERC-20 tokens or use ETH in apps using the ERC-20 standard. Ethereum's native currency Ether (ETH) can't be used for a majority of apps built around ERC-20s, but when you wrap it you get an ERC-20 token that lets you use your ETH holdings with smart contracts, and app developers don't need to add extra logic to support ETH interactions. WETH is therefore not primarily a cross-chain bridge token. It is a formatting adapter. When a counterparty offers WETH on Ethereum, the custodial layer is a well-audited smart contract, not a third-party institution, which materially changes the risk profile compared to a cross-chain wrapped token like WBTC. **cbBTC — Coinbase Wrapped Bitcoin** Launched by Coinbase in September 2024, right as the WBTC controversy was peaking, cbBTC is fully custodied by Coinbase and works on Ethereum, Base, Solana, and Arbitrum. Adoption has been rapid; it became one of the leading BTC collateral assets on Aave within its first year. It is unambiguously centralized, but Coinbase's regulatory standing and institutional credibility give many users comfort. Other wrapped tokens will surface in deals. The due-diligence framework in the decision framework section of this article applies to all of them. ## Why professionals encounter wrapped tokens in deals The rise of onchain settlement has created a new pattern: counterparties who hold significant wealth in Bitcoin or Ethereum want to use it in deals without first converting back to fiat. They may also arrive on the other side of a DeFi position — carrying WBTC or WETH as collateral they have just unwound — and offer it directly as payment. Wrapped tokens expand access to decentralized finance applications. Holders of assets like Bitcoin can now participate in yield-generating activities such as lending, borrowing, and staking. Instead of holding idle assets in a wallet, users can put their capital to work within smart contracts to earn a return. This expanded utility transforms static assets into productive capital, driving the growth and adoption of onchain financial products. For brokers, OTC desks, and settlement agents, this means the incoming payment leg of a deal may increasingly arrive in a form that is neither stablecoin nor native ETH. Understanding what these assets are — and what they are not — is now part of the professional competence required for onchain settlement. There is also a practical Ethereum-specific reason why WETH appears in payment flows: a wrapped token functions as a tokenized crypto asset that retains the same value as its underlying asset, enabling interaction across various blockchain ecosystems to benefit from features like faster transactions, lower fees, and decentralized application functionality. When a routing tool such as shaka.deal distributes proceeds across parties simultaneously, it handles ERC-20 tokens uniformly. WETH, being ERC-20 compliant, moves through smart contract logic cleanly and settles to every preset share in one transaction — exactly the same as any other ERC-20. ## The peg: what holds it and what can break it Wrapper risk is the risk that a tokenized claim stops being freely convertible to its underlying asset at par. "1:1 pegged" is only as strong as the redemption path, reserve integrity, and settlement reliability that support it. That sentence deserves to sit at the centre of every professional's thinking before accepting a wrapped token. The peg is not a guarantee. It is an equilibrium maintained by three mechanisms: arbitrage, reserve transparency, and open redemption. When any one of those three fails, the peg can drift. **Arbitrage-maintained equilibrium** Under normal conditions, the peg is held together by arbitrageurs who can mint and redeem to capture price differences. During a panic, a custodian controversy, a bridge hack, or a liquidity crunch, the peg can break. A wrapped token maintains its value only as long as market participants believe it can be redeemed for the underlying asset on a 1:1 basis. **Reserve transparency** Reputable wrapped tokens publish regular attestations confirming that the reserves back the circulating supply. Chainlink Proof of Reserves is one standard. If you can't find this, proceed with extra caution. A wrapper can be "backed" and still not be safe: reserves can be impaired by losses, reserves can be encumbered by lending or rehypothecation, reserves can be temporarily borrowed to window dress. When reserves are impaired, the wrapper becomes a claim on a hole, and the peg becomes a market estimate of recovery value. **Redemption path integrity** If the bridge is hacked, paused, or halts due to validator failure, the wrapper can lose its redemption path. Without redemption, arbitrage cannot restore parity, and the wrapper price becomes a separate market. Real events illustrate how quickly this plays out. WBTC traded at a discount during the 2024 BiT Global fallout. That 2024 custody controversy demonstrated how quickly confidence can erode when custody arrangements change. WBTC briefly traded at a discount to BTC in November 2022, dropping to approximately 0.9852 BTC during the FTX collapse. Even well-established bridge infrastructure carries structural risk. Bridge exploits have caused some of the largest losses in DeFi history. The Ronin Bridge hack in March 2022 drained approximately $625 million in ETH and USDC from the bridge reserves backing Ronin's wrapped tokens. Wormhole's Solana to Ethereum bridge accepted a forged signature set because of a signature verification bug, and the attacker minted 120,000 wETH on Solana without locking any ETH on Ethereum. Jump Crypto replaced the stolen funds out of its own treasury within 24 hours, which is why Wormhole still exists. The pattern in these incidents is consistent. If a bridge is exploited, the attacker may mint unbacked wrapped tokens or drain the locked reserves. In either case, the wrapped tokens in circulation may no longer be fully backed, causing the token to depeg from the underlying asset. ## The four specific risks a professional must evaluate When a wrapped token arrives as the payment leg of a deal, four risk categories need explicit evaluation. ### 1. Custodian counterparty risk Custodial wrapped tokens introduce centralization risks, as users must trust third parties to maintain reserves and honor redemptions. If a custodian becomes insolvent, gets hacked, or acts dishonestly, wrapped token holders could lose value. Users must trust the issuer of the wrapped tokens to mint and redeem native assets when requested. They must also rely on custodians to guarantee the security of assets held in reserve. These single points of failure can make wrapped tokens significantly higher risk than other asset types. The relevant question here is not "is the custodian big?" but "is custody multi-institutional, audited, and transparent?" | Token | Custody model | | --- | --- | | WBTC | Multi-signature governance, whatever its controversies | | cbBTC | Custody concentrated with a single regulated entity | | tBTC | Trust distributed across a decentralized staker network | These are materially different risk profiles even though all three track BTC at 1:1 under normal conditions. ### 2. Smart contract risk Additional risks with wrapped tokens come from the introduction of extra smart contracts into the chain. Smart contract vulnerabilities present a significant threat. The minting, burning, and bridging processes rely on complex code. If there is a flaw in the smart contract governing the wrapped token or the cross-chain bridge, malicious actors can exploit it to drain the underlying reserves. Bridge exploits have historically resulted in substantial financial losses. Even well-audited contracts carry risks. Users should verify that wrapped token protocols have undergone multiple independent audits, have active bug bounty programs, and maintain robust security practices. Using established, battle-tested wrapped tokens reduces but doesn't eliminate this risk. ### 3. Depeg and liquidity risk In extreme market conditions, wrapped tokens may temporarily lose their 1:1 peg to underlying assets if redemption mechanisms experience delays or if liquidity becomes insufficient. While rare, these depegging events can cause panic and price volatility. Users should monitor liquidity levels and be cautious during market stress when redemption queues might lengthen or fees might spike. Even when the underlying reserves are intact, market stress can temporarily decouple the wrapped token's market price from its 1:1 peg. This happened to stETH in June 2022 and to many bridge wrappers during the Multichain collapse. For a deal that closes at a USD $2,000,000 (AUD ~$3,100,000) value, a 1.5 percent depeg on WBTC means the receiving parties absorb $30,000 (AUD ~$46,500) in unexpected basis risk before they can liquidate. That is not a hypothetical haircut. It happened during the FTX collapse when WBTC dropped to approximately 0.9852 BTC. A settlement agent whose distribution was preset in wrapped token terms would have delivered under-value to every recipient. Liquidity fragmentation is an additional concern. The same underlying asset can be wrapped multiple times across multiple chains, fragmenting liquidity. Trading WBTC on Optimism might face higher slippage than trading WBTC on Ethereum simply because the bulk of liquidity sits on mainnet. ### 4. Regulatory and operational risk Custodial wrappers operate under specific regulatory regimes. Changes in those regimes — a new sanctions list, a new licensing requirement, a new tax treatment — can force the custodian to freeze certain addresses or pause redemptions. This risk has grown significantly as regulatory clarity has expanded in major jurisdictions. A frozen redemption path does not make a wrapped token worthless, but it does make it illiquid at exactly the moment liquidity is needed. Settlement agents have an obligation to ensure proceeds actually reach their recipients. A wrapped token whose redemption is administratively paused cannot fulfill that obligation. ## A practical decision framework: should you accept it? The answer is not a flat yes or no. It depends on the specific token, the specific custodial structure, the deal size, and how quickly the proceeds need to move downstream. Here is a structured way to work through the decision.
Accepting a wrapped token: five stepsWork through them in order before the deal closes
  1. Identify whether it is a cross-chain wrapper or a same-chain adapterWETH on Ethereum is a same-chain adapter. The smart contract is simple, widely audited, and the "custodian" is Ethereum's own blockchain infrastructure. The depeg risk is minimal. WBTC or cbBTC on Ethereum is a cross-chain wrapper. The underlying asset sits on a different blockchain entirely, in the custody of a company or consortium. The risk profile is higher and requires further evaluation.
  2. Verify proof-of-reservesActively monitor the price of wrapped tokens relative to their underlying assets. Deviations from the 1:1 peg, even small ones, can signal underlying issues with the custodian, bridge, or reserve backing. Set up alerts for peg deviations on platforms like CoinGecko or DeFiLlama. Before accepting, check whether the wrapped token publishes on-chain or third-party reserve attestations. If the protocol cannot demonstrate that the circulating supply is fully backed at the moment of settlement, the peg is a trust claim rather than a verifiable fact.
  3. Check secondary market liquidity and current pegPull the WBTC/BTC or WETH/ETH price on a DEX aggregator at the time of deal closing. Under normal conditions, the spread is negligible. If you see a premium or discount, that is a real-time signal about market confidence in the redemption path. A discount of more than 10 basis points on a deal-size payment warrants further investigation before proceeding. For large transactions — say USD $5,000,000 (AUD ~$7,750,000) or more — also check order book depth on major DEXs on the chain you will receive the token. The most reliable due diligence checks are mechanical: how redemption works, who controls minting and upgrades, whether reserves are transparent and unencumbered, and whether secondary market liquidity can absorb exits.
  4. Decide whether to convert at close or holdIf the deal logic requires you to distribute proceeds in the same token across multiple parties — for example, a WBTC payment split among a seller, a broker, and a title company — then the routing happens cleanly. shaka.deal handles ERC-20 tokens natively, which means a single incoming WBTC payment can be split to preset percentage shares for every party simultaneously, in one transaction, with immediate finality. Settlement is not sequential and it is not conditional: every party receives their share at the same moment the transaction confirms on chain. There is no follow-on leg to manage. However, if any of the receiving parties needs fiat or native ETH within a short window, plan for conversion. Holding wrapped tokens idle exposes you to custodian and bridge risk without any corresponding benefit. If you're not actively using the wrapped position, unwind it.
  5. Document the token's contract address, chain, and custodianThis is not optional. A wrapped version of a coin is not that coin. It's another cryptocurrency entirely. Many financial and legal practitioners have discovered this the hard way when WBTC appeared in a statement of closing funds and was booked at BTC value without acknowledging that the underlying was held by a third-party custodian with its own risk profile. Document clearly which token, on which chain, issued by which protocol, at what peg reading at time of close.
## The routing question: what shaka.deal actually does with a wrapped token shaka.deal is an onchain payment router on Ethereum. When a deal is structured with preset distribution shares — seller, agent, attorney, lender, or any other party — and the incoming payment arrives in an ERC-20 token, the router splits and distributes that total amount simultaneously to every wallet in the preset split. One incoming transaction, one on-chain confirmation, every party paid at the same instant. Because WETH and WBTC and cbBTC all conform to the ERC-20 standard on Ethereum, they move through this routing logic the same way any other ERC-20 does. The router does not hold funds at any point. It receives the single incoming amount and routes it outward in the same transaction. There is no float, no settlement lag, no sequence of individual transfers that could partially fail. The certainty that a settlement agent, OTC desk, or closing attorney needs — the confirmation that every party received exactly their share and that the payment is complete — is delivered in one block. The one thing shaka.deal cannot do is evaluate the quality of the peg at the moment a payment is initiated. That evaluation is the professional's job, and the due-diligence steps above are exactly what makes an informed accept or reject decision possible. Once a settlement agent has done that work and determined the token is sound, the routing side of the equation is clean: predetermined shares, instant simultaneous distribution, final settlement. ## Summary: what to take away A wrapped token is a tokenized representation of another asset, issued on a blockchain where that asset is not native, maintained at 1:1 parity through custodial reserves or smart contract logic, and redeemable for the underlying at any time under normal conditions. The major examples in professional deal flows are WBTC, cbBTC, and WETH. The 1:1 peg is real and reliable under normal conditions. It is not guaranteed under stress. Custodian failure, bridge exploits, reserve opacity, and regulatory freezes have all caused real depegs — not theoretical ones — in recent years. The magnitude and duration of these depegs has ranged from brief basis-point discounts to complete irredeemability (as in the case of soBTC after FTX's collapse). When the mechanics of a wrapped token are understood, it can be used intentionally rather than treated as interchangeable cash. That sentence is the right frame for a professional deciding whether to accept a wrapped token as the payment leg of a deal. Know which token you are receiving. Verify the reserve backing. Check the current peg. Assess whether the receiving parties can absorb any residual conversion lag or slippage. Once those boxes are checked, onchain settlement tools can do exactly what they are designed to do: route the total amount to every party, in the right shares, instantly, with finality.
