How to bridge from BTC to ETH

A real case from June 2026: a user bridged 0.063449 BTC (~$4,056) of native Bitcoin and received 2.342914 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. A Bitcoin wallet on the source side and an EVM wallet (MetaMask) on the Ethereum side. Symbiosis resolved the destination address automatically from the connected EVM wallet — no manual paste required.
Entered the amount. 0.063449 BTC (~$4,056). 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. The quote was locked in before signing, with slippage tolerance protecting against sudden price moves.
Signed and confirmed. Checked the self-custodial confirmation and signed the Bitcoin transaction. Native ETH arrived in the EVM wallet within the expected window (~586 sec, given Bitcoin confirmation times). The transaction is fixed on-chain — verifiable on Symbiosis Explorer, mempool.space, and Etherscan.

About the BTC to ETH route

1,476 outbound transactions over 90 days — BTC to ETH is one of the strongest Bitcoin-origin corridors on the Symbiosis routing layer.
Cumulative volume $17.7M over 90 days, up +536% quarter-over-quarter — one of the fastest-growing routes on the network.
Bridges settle in a median of ~544 sec, with 90% completing under 1,594 sec — pacing is driven by Bitcoin block confirmation times.
Transaction size mix: 38.21% small, 35.64% mid-size, 24.39% large, 1.76% whale — the demo's ~$4,056 sits in the mid-tier band.
Native BTC in, native ETH out — no wrapped tokens held by the user at the destination; Symbiosis settles through its syBTC layer under the hood.
Note: Bitcoin-origin sender addresses are not captured in the explorer, so unique-wallet counts are not reported for this corridor.

Popular routes via Bitcoin: BTC to ETH, BTC to Arbitrum, BTC to BNB Chain, ETH to BTC.

Two-layer staking security

Cross-chain transactions routed via Octopools AMM (scans liquidity across DEXs and chains for minimal slippage), then signed by an MPC group via Threshold Signature Scheme (TSS) — no single party can move user funds. Two security layers: Symbiosis PoS Staking (SIS-collateralised relayer nodes) + Symbiotic restaking (additional slash-able collateral). 2/3 stake quorum for epoch changes.

Two-layer staking security

$8B+ across 54 chains

$8B+ total volume bridged across 5M+ transactions from 800K+ unique wallets. Supports 54 networks — more than any other cross-chain bridge (Across 35+, deBridge 30+, Allbridge 20). EVM + non-EVM in one route — Ethereum, Solana, BNB Chain, TON, Tron, Bitcoin, Arbitrum, Polygon, and 46 more. Per-transaction range: $10 to $140,000 — handles retail swaps and whale trades on the same route.

How do I bridge BTC to ETH?

Connect a Bitcoin wallet as the source and an EVM wallet (e.g. MetaMask) as the destination on Symbiosis, enter the BTC amount, review the quote, and sign the Bitcoin transaction. You receive native ETH on Ethereum — no wrapped tokens. A real $4,056 bridge settled in ~586 sec.

Do I get native ETH or wrapped ETH when bridging from Bitcoin?

You receive native ETH on Ethereum. The widget routes BTC through Symbiosis's syBTC settlement layer and delivers native ETH to your wallet — there's nothing for you to unwrap afterward.

How long does a BTC to ETH bridge take?

Over the last 90 days the median settlement was ~544 sec, with 90% of bridges completing under 1,594 sec. Timing is paced by Bitcoin block confirmations, so larger or congested-network transfers sit toward the higher end.

How much does it cost to bridge BTC to ETH?

Symbiosis charges a flat protocol fee that grows with route complexity, not amount. Sample quotes range from ~$1.14 on a $500 transfer to ~$10.64 on a $10,000 transfer. You also pay the standard Bitcoin network mining fee from your source wallet.

Is bridging BTC to ETH on Symbiosis non-custodial?

Yes. Funds stay in your own wallets at every step — you sign the Bitcoin transaction yourself and the destination ETH is delivered directly to your connected EVM wallet. No intermediary takes custody.

Can I bridge ETH back to BTC?

Yes. The same widget supports the reverse direction — bridge ETH on Ethereum back to native BTC on Bitcoin, settled through the same syBTC layer.

Can I verify a BTC to ETH bridge on-chain?

Yes. Every bridge is traceable across three explorers: Symbiosis Explorer for the cross-chain leg, mempool.space for the Bitcoin transaction, and Etherscan for the Ethereum receipt. The demo here links all three.

What's the minimum amount to bridge BTC to ETH?

Sample tiers start at 0.0078078 BTC (~$500). Because the protocol fee is flat rather than percentage-based, smaller transfers carry proportionally higher cost — enter your amount in the widget for an exact live quote before signing.
