Swap WBTC

Swap WBTC is a reference page for WBTC, an ERC-20 representation of Bitcoin that smart contracts can read; the ERC-20 token standard defines functions for balances, transfers, approvals, and decimals. On Ethereum it is an ERC-20 with 8 decimals — deliberately matching BTC's own precision — and every WBTC in circulation corresponds to BTC held by authorized custodians.

Native BTC cannot natively interact with EVM liquidity pools, lending markets, or routers, so WBTC makes Bitcoin value usable in those DeFi systems. The peg holds through arbitrage between WBTC's market price and the redeemable BTC, while the redemption claim still depends on the custodial layer behind it rather than code alone.

Getting in and out means trading WBTC on its smart-contract chain or using a separate route to native BTC. Most users never mint WBTC directly — minting is handled by merchants interacting with custodians — so you typically acquire WBTC by swapping another token for it on a DEX, buying it where listed, or following a documented route to convert BTC to WBTC.

A same-chain swap can turn WBTC into ETH or a stablecoin. Converting WBTC into native BTC requires a redemption through a merchant, a centralized exchange, or a cross-chain service that handles the leg between the token contract and the Bitcoin network.

A same-chain WBTC swap is a router calling one or more liquidity pools and sending the output to your wallet, as described in this Ethereum token-swap guide. Connect a self-custody wallet, choose WBTC as input or output, and inspect the quoted route, expected output, price impact, slippage limit, and fees.

Two transactions can be involved: if your allowance is insufficient, you first sign a token approval authorizing the router to spend your WBTC, then sign the swap itself. Large orders against thin pools show up as price impact; the minimum-received setting stops execution beyond your slippage tolerance. Settlement is final once the transaction confirms.

WBTC and native BTC are different instruments: WBTC tracks BTC's price because each token is backed 1:1 by custodied BTC, while native BTC settles on its own chain with no issuer and no contract. WBTC market data lets you compare their market prices; WBTC also inherits smart-contract, approval, and custodian risk in exchange for composability.

Use WBTC when you need Bitcoin exposure inside DeFi as collateral, liquidity, or a trading pair on EVM chains. Use native BTC when you want the asset itself with no intermediary. Swapping WBTC into ETH or stables stays on-chain; converting it back to BTC needs a redemption or bridge flow.

The cost of a WBTC action is gas in the network's native token — ETH on Ethereum — whether the transaction succeeds or reverts; this Ethereum gas explainer describes why the fee is required. If a token approval is needed first, it is a separate transaction with its own gas cost.

A DEX swap also includes liquidity-provider or route fees built into the quote, price impact from your order moving the pool, and any disclosed interface fee. The useful cost is the gap between the mid-price and what lands in your wallet, so compare expected output and minimum received. A failed or stuck transaction still burns gas.

Use Swap WBTC only after matching the chain-specific contract address: on Ethereum Mainnet (chain ID 1), WBTC is 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599; check that address on the block explorer, because anyone can deploy a token called "WBTC" and every other network has its own contract.

The dashboard never asks for a seed phrase or private key, and your wallet signs execution. The remaining risk stack includes custodians holding the backing BTC, smart-contract failure, malicious approvals, counterfeit tokens, MEV, slippage, low liquidity, and cross-chain risk if you bridge or redeem. Audited, long-lived code can reduce some uncertainty but does not remove those dependencies.

Fix a failed WBTC swap by checking the network and token, the native gas balance, and the token allowance in that order.

Wrong network or wrong token. If your WBTC balance shows zero, check the chain first: WBTC exists on multiple networks with different contracts, and your wallet may be pointed at the wrong one. Confirm the contract address before assuming funds are lost.

No gas. You cannot spend WBTC to pay for its own transaction; you need the native gas token (ETH on Ethereum) in the same wallet. Approval confusion. If the interface asks to approve again, your existing allowance is insufficient or you switched routers; approvals are per-token, per-spender, per-chain. Wrong action. If you wanted native BTC and swapped into ETH instead, native-BTC delivery needs a redemption, exchange, or bridge flow.
