How to bridge from BTC to ETH
A real case from September 2026: a user bridged 0.059350 BTC (~$4,993) of native Bitcoin and received 1.841577 ETH on Ethereum via Symbiosis — no wrapped tokens, fully non-custodial. BTC to ETH is one of the most popular Bitcoin-origin corridors on Symbiosis; this is shown as a representative example. Here's the exact flow:
Picked the source. Bitcoin as source, Ethereum as destination — native BTC in a Bitcoin wallet, with the goal of holding native ETH for Ethereum DeFi (Uniswap, Aave, Lido).
Connected wallets. An EVM wallet (MetaMask) on the Ethereum side — Symbiosis resolved the destination address automatically from it. The Bitcoin side needs no wallet connection: BTC is sent to a one-time deposit address from any Bitcoin wallet.
Entered the amount. 0.059350 BTC (~$4,993). The Bitcoin wallet held enough BTC to cover the network mining fee on top of the bridged amount.
Reviewed the quote. Symbiosis displayed the route through its syBTC settlement layer, expected receipt in native ETH, fee, ETA, and price impact upfront. After confirming, Symbiosis issued a one-time Bitcoin deposit address with a 20-minute window to send the exact amount, with slippage tolerance protecting against sudden price moves.
Sent and confirmed. Sent exactly 0.059350 BTC from a Bitcoin wallet to the deposit address. The status moved through Send funds, Swap, Sending funds and Received, and native ETH arrived in MetaMask (~117 sec for the cross-chain leg, per Symbiosis Explorer). Bitcoin-origin swaps can take up to 50 minutes in total; the tracking link can be copied to follow the status later. The transaction is fixed on-chain — verifiable on Symbiosis Explorer, mempool.space, and Etherscan.
About the BTC to ETH route
Why this route. Converting BTC into ETH opens Ethereum-only uses: staking with Lido for stETH, lending on Aave V3, or trading on Curve and Uniswap.
What you receive. Native ETH at the EVM wallet you connect; since ETH is also gas on Ethereum, your next transaction needs no top-up. The app shows a one-time Bitcoin deposit address, and you send BTC to it.
Watch out for. Send within 20 minutes of the address appearing and never reuse it. The Bitcoin network fee comes from your wallet on top of the amount. Exchange withdrawals can sit in a queue past that window, so send from a wallet you control.
Speed. Median delivery 9 minutes; 90th percentile 29 minutes, over the 90 days to 25 September 2026.
