How the ARB to OP route works
This route spans two networks: ARB leaves your wallet on Arbitrum One and OP settles on Optimism. NativeSwap routes it natively, so no centralized bridge sits in the middle and you do not receive a wrapped token.
- You send
- ARB is the native coin of Arbitrum One. You sign the transaction on Arbitrum One, so that network's gas fee applies.
- You receive
- OP is the native coin of Optimism. Optimism arrives at an address you control on Optimism.
Arbitrum settles on Arbitrum One; Optimism settles on Optimism. You pay network gas on Arbitrum One plus a service fee of roughly 10-15 basis points; swaps under $10 have no service fee. Settlement time depends on how quickly each network confirms, and an estimate is shown before you confirm.
