How Arbitrum → BNB Smart Chain routing works
Bridge ETH/USDC across Arbitrum and BNB Smart Chain L2s without leaving EVM — Ropil routes through bridge aggregators that solve this in seconds.
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. Typically deepest for Arbitrum ↔ BNB Smart Chain.
- Relay uses an intent / solver model. Often fastest (under 30 seconds) for stablecoin movements between EVM L2s.
- THORChain runs native cross-chain pools. Falls back to native-asset routing if LiFi and Relay both lack liquidity for Arbitrum ↔ BNB Smart Chain.
What you need
- A self-custodial wallet (MetaMask, Rabby, WalletConnect).
- ETH on Arbitrum to pay for the input + gas.
- A receiving address on BNB Smart Chain (your wallet handles this).
Before you click swap, read the risk disclosure — cross-chain swaps are irreversible and a bridge failure can strand funds.
