BTC to WBTC Exchange

Bitcoin cannot interact with Ethereum smart contracts natively. BTC runs on its own blockchain, and Ethereum-based DeFi protocols — lending markets, liquidity pools, yield strategies — require ERC-20 tokens to function.

A BTC to WBTC conversion solves this: Wrapped Bitcoin (WBTC) is an ERC-20 token backed 1:1 by real Bitcoin, held in reserve by custodian BitGo. Each WBTC equals exactly one BTC in value, but it runs on the Ethereum network — making Bitcoin-linked value usable across Aave, Compound, Uniswap, Curve, and other Ethereum DeFi protocols.

Users who convert BTC to WBTC typically do so to use Bitcoin as collateral for stablecoin loans without selling their BTC position, to provide liquidity in WBTC trading pairs and earn swap fees, or to access yield strategies on Ethereum that require ERC-20 collateral.

Most exchange partners start processing a BTC to WBTC swap after 3–6 Bitcoin network confirmations. Bitcoin produces a new block approximately every 10 minutes, so 3 confirmations take roughly 30 minutes and 6 confirmations take approximately 60 minutes before the partner begins conversion.

During periods of Bitcoin mempool congestion — high-fee competition for block inclusion — that window extends if your transaction fee is set too low.

On the WBTC side, the output token is an ERC-20 token on Ethereum. Incoming WBTC requires 12–35 Ethereum confirmations before it is credited, depending on the receiving wallet or platform. Ethereum produces a block every 12 seconds, so 12 confirmations add roughly 2–3 minutes on the receiving end.

Total swap time under normal network conditions: 30–70 minutes from BTC send to WBTC credited.

WBTC does not require a MEMO, payment tag, or destination tag — no additional destination data is required beyond the ERC-20 wallet address. Send WBTC only to an Ethereum-compatible wallet address (MetaMask, Ledger, hardware wallet). Sending to a Bitcoin address will result in lost funds.

• Pasting a Bitcoin address as your WBTC destination WBTC is an ERC-20 token. It must be received by an Ethereum wallet address. Sending to a BTC address will result in permanently lost funds.

• Setting BTC fee too low Low fee rates during mempool congestion can stall your Bitcoin transaction for hours. Check mempool conditions on mempool.space before sending and set a fee that targets confirmation within the next 1–3 blocks.

• Selecting a floating-rate offer and ignoring BTC confirmation time The 30–70 minute processing window is long enough for the BTC/WBTC rate to move. For larger amounts, fixed rate removes that exposure.

• Sending from an exchange withdrawal address Send BTC from a self-custodied wallet, not directly from a CEX. Some exchange withdrawals are batched and delayed, which can affect confirmation timing and order matching.
