How to Bridge ETH to Bitcoin
Bridging ETH to Bitcoin is a cross-VM transfer — assets leave Ethereum's EVM and arrive on Bitcoin as native BTC, not as WBTC or any wrapped token. Bitcoin wallets do not support WalletConnect, so the destination Bitcoin address is pasted manually rather than auto-resolved.
Connect your EVM wallet. MetaMask, Trust Wallet, or Rabby for Ethereum. Bitcoin wallets (Sparrow, Electrum, Xverse) do not connect via WalletConnect — they're only used to receive.
Select source. Choose Ethereum and ETH as the source asset.
Paste your Bitcoin address. Copy your Bitcoin native SegWit (bc1q...) or legacy (1...) address from your Bitcoin wallet and paste it as the destination. Double-check the address — Bitcoin transactions are irreversible.
Review the quote. Verify the BTC output, Symbiosis fee, and route time. Bitcoin confirmation requires 1+ network confirmations (~10 minutes per block).
Confirm and sign. Sign the Ethereum source transaction. Native BTC settles to your Bitcoin address after Bitcoin block confirmation. The transaction is final once confirmed on the Bitcoin network.
About ETH to Bitcoin route
ETH to Bitcoin is one of the few EVM-to-Bitcoin routes that delivers native BTC instead of WBTC, tBTC, or other wrapped representations. The cohort using this route is users wanting actual Bitcoin holdings (cold storage, hardware wallet, sovereignty) rather than ERC-20 IOU exposure to BTC. Symbiosis handles the cross-VM execution including the source-to-Bitcoin settlement complexity. If you want a wrapped BTC representation on Ethereum instead, see our blog on how Symbiosis went full Bitcoin.
Important UX exception: because Bitcoin wallets don't support WalletConnect, the destination address must be pasted carefully. Triple-check the Bitcoin address before signing — Bitcoin has no rollback.
Other ETH routes
ETH → Solana — native SOL via EVM-to-SVM route
ETH → Tron — native TRX, gateway to USDT-TRC20

01
Will I receive native BTC or wrapped BTC?
Symbiosis delivers native BTC — actual Bitcoin to your Bitcoin address — not WBTC, tBTC, or any wrapped representation. Wrapped Bitcoin tokens (like WBTC on Ethereum) are ERC-20 IOUs that depend on a custodian or bridge contract holding the underlying BTC. Native BTC has none of that counterparty risk: once it arrives at your Bitcoin address, you control it directly with your Bitcoin wallet keys.
02
Why do I have to paste my Bitcoin address manually?
Bitcoin wallets (Sparrow, Electrum, Xverse, Ledger Bitcoin app, hardware wallets) don't support WalletConnect — that protocol is EVM-specific. So Symbiosis cannot auto-resolve your Bitcoin destination from a connected wallet the way it can for Solana or Tron. You copy the receiving address from your Bitcoin wallet and paste it into Symbiosis. Triple-check the address before signing — Bitcoin transactions are irreversible.
03
How long does ETH to Bitcoin bridging take?
The Ethereum side confirms in 12–60 seconds, then Symbiosis routes to Bitcoin which requires Bitcoin block confirmation (~10 minutes per block, typically 1–3 confirmations for safety). End-to-end: 10–30 minutes is typical, longer than EVM-to-EVM routes due to Bitcoin's 10-minute block target. The progress UI shows current status: source confirmed, routing, Bitcoin confirmation.
04
What Bitcoin address formats does Symbiosis support?
Symbiosis accepts native SegWit (bc1q...), Taproot (bc1p...), and legacy (starting with 1 or 3) Bitcoin addresses. Native SegWit is recommended — lower fees on the Bitcoin side, broad wallet support. Verify the address format matches your wallet expectation. Wrong address format means lost funds with no recovery.
05
How much does it cost to bridge ETH to Bitcoin?
Costs include Symbiosis protocol fee, Ethereum source gas ($1–$15 typical in 2026), and Bitcoin network fee (sat/vB rate at time of settlement, varies with mempool). Bitcoin fees can spike during congestion. Total shown upfront in the quote before you confirm. Routing to Solana can be cheaper if you don't specifically need native BTC.
06
What's the difference between native BTC and WBTC?
Native BTC sits at a Bitcoin address controlled by your Bitcoin wallet keys — it's real Bitcoin, no intermediary. WBTC is an ERC-20 token on Ethereum (or other EVM chains) backed 1:1 by BTC held by a custodian (BitGo, etc.). WBTC works in Ethereum DeFi (Aave, Curve, lending markets) but carries custodian risk and depends on the wrapping system staying solvent. Use WBTC for EVM DeFi, use native BTC for cold storage, hardware wallets, or on-chain Bitcoin uses.
07
Can I bridge BTC back to ETH later?
Yes — Symbiosis runs Bitcoin→Ethereum routes too. You initiate from a Bitcoin wallet (sending native BTC to a deposit address shown in the quote), and ETH arrives at your Ethereum wallet after Bitcoin confirms. Same cross-VM mechanic in reverse. Useful for users moving between cold storage and active DeFi positions.
08
Is bridging ETH to Bitcoin via Symbiosis safer than a CEX?
A centralized exchange route requires depositing ETH (custody risk + KYC), trading ETH/BTC, then withdrawing BTC (more custody risk + withdrawal limits + delays). Symbiosis is non-custodial: smart contracts execute the cross-VM transfer, you sign yourself, no signup. The trade-off is that you must paste the Bitcoin address correctly (one mistake = irreversible loss), versus CEX-specific risks like withdrawal freezes or custody loss.
