Native ETH ↔ BTC swaps route through THORChain — landing in v1.1. The widget above covers EVM routes today; for the native flow now, read the step-by-step guide.
How Arbitrum → Bitcoin routing works
Swap ETH for native BTC via THORChain — non-custodial, no wrapped tokens, no centralized exchange in the loop.
Ropil queries three independent protocols and uses whichever returns the best output amount in USD, accounting for slippage and network fees:
- LiFi aggregates bridges and DEXes across EVM chains. Not in the route for this pair — Arbitrum ↔ Bitcoin crosses a non-EVM chain.
- Relay uses an intent / solver model. Often fastest (under 30 seconds) for stablecoin movements between EVM L2s.
- THORChain runs native cross-chain pools. Required for Arbitrum ↔ Bitcoin — handles native Bitcoin, Litecoin, Dogecoin, and Bitcoin Cash without a centralized exchange.
What you need
- A self-custodial wallet (MetaMask, Rabby, WalletConnect).
- ETH on Arbitrum to pay for the input + gas.
- A receiving address on Bitcoin (your wallet handles this).
Before you click swap, read the risk disclosure — cross-chain swaps are irreversible and a bridge failure can strand funds.
