CROSS-CHAIN GUIDE

How to bridge from Ethereum to Bitcoin

A real case from June 2026: a user bridged 5.6971 WETH (~$9,600) from Ethereum and received 0.150830 BTC on Bitcoin via Symbiosis — no wrapped tokens beyond the standard route, fully non-custodial. Symbiosis works as a liquidity meta-aggregator, comparing routes across multiple DEXes and bridge providers and picking the best one by price, fee, and speed automatically. This is one of the most popular flows on this corridor; the same widget supports any source chain and token combination. Here's the exact flow:

  1. Picked the source. Ethereum as source, Bitcoin as destination — the WETH sat in an Ethereum wallet and the goal was access to native BTC custody and Bitcoin payments.

  2. Connected wallets. MetaMask on the Ethereum side, Xverse on the Bitcoin side. Symbiosis resolved the destination address automatically from the connected wallet — no manual paste required.

  3. Entered the amount. 5.6971 WETH (~$9,600). The Ethereum wallet had enough balance to cover network gas.

  4. Reviewed the quote. Symbiosis displayed the exact BTC amount on Bitcoin, the flat Symbiosis fee in USD, and ETA. The quote was locked in before signing — 2% slippage tolerance protects against sudden price moves.

  5. Signed and confirmed. Signed the Ethereum transaction in MetaMask. BTC arrived in Xverse within ~5949 sec. The transaction is fixed on-chain — verifiable on Symbiosis Explorer, Etherscan, and Blockstream Explorer.

WHY SYMBIOSIS

Secure by design. Proven at scale

Audited in the open

No KYC, no custody, no intermediaries. Audited by Decurity, Zokyo, SlowMist, and Omniscia — 13 public audit reports across 11 protocol modules (Core, MetaRouter v3, Pool, TON Bridge v1+v2, Relayers Network, Staking, Frontend). All reports open-source on GitHub. 4+ years live on mainnet (since March 2022) with zero major security incidents. Active bug bounty program.

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.

$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.

01

Can I bridge ETH to BTC?

Yes. Symbiosis lets you move value from Ethereum to Bitcoin in a single non-custodial flow, with no KYC required. Over the last 90 days the route handled $25.05M across 988 transactions from 380 unique wallets, with QoQ growth of +67%.

02

How do I convert Ethereum to Bitcoin?

Connect your wallet to the Symbiosis widget, select Ethereum as the source and Bitcoin as the destination, then enter the token and amount you want to send. Paste your BTC receiving address, confirm the quote, and approve the transaction. Most transfers settle around the 800-second median, with 90% completing within 2110 seconds.

03

What is the ETH to BTC bridge price?

Pricing is shown live in the widget before you confirm. Recent quotes include 100 USDC for 0.001551 BTC, 1,000 USDC for 0.015596 BTC, and 5,000 USDC for 0.077973 BTC, each with a 0.0000 routing fee. Rates update with the market, so always check the on-screen quote at the time of your transfer.

04

What is the cheapest way to convert ETH to BTC?

Routing through Symbiosis keeps costs low: the live quote tiers show a 0.0000 routing fee on amounts from 100 USDC up to 5,000 USDC. Because it is non-custodial and requires no KYC, you avoid exchange account overhead while still getting a transparent rate before you confirm.

05

Is there an ETH to BTC bridge calculator?

Yes. The Symbiosis widget acts as a live calculator: enter your Ethereum-side amount and it returns the exact BTC you will receive. For reference, 500 USDC currently quotes to 0.007795 BTC and 5,000 USDC to 0.077973 BTC, each delivered in roughly 811 seconds.

06

What happens if you send ETH to a BTC wallet?

Sending native ETH directly to a Bitcoin address will result in lost funds, since the two networks are not compatible. To move value safely, use the Symbiosis bridge, which routes from Ethereum and delivers actual BTC to a valid Bitcoin address you provide. Always double-check the destination address in the widget before confirming.

07

Should I convert Ethereum to Bitcoin?

That depends on your own strategy, and this is not financial advice. What Symbiosis provides is a reliable, audited, non-custodial path when you do decide to move from Ethereum to Bitcoin, with a median delivery of 800 seconds. The most-bridged token on this route is syBTC at 73.2% of volume, followed by USDC at 25.6%.

08

Which tokens can I bridge from Ethereum to Bitcoin?

On this route the leading tokens by volume are syBTC at 73.2%, USDC at 25.6%, and WETH at 1.2%. You select your input token in the widget and receive BTC on Bitcoin. The supported list and live quote appear before you confirm.
