How the ATOM to ARB route works
This route spans two networks: ATOM leaves your wallet on Cosmos Hub and ARB settles on Arbitrum One. NativeSwap routes it natively, so no centralized bridge sits in the middle and you do not receive a wrapped token.
- You send
- this route uses ATOM on Cosmos Hub. You sign the transaction on Cosmos Hub, so that network's gas fee applies.
- You receive
- ARB is the native coin of Arbitrum One. Arbitrum arrives at an address you control on Arbitrum One.
Cosmos settles on Cosmos Hub; Arbitrum settles on Arbitrum One. Assets issued on more than one network can be routed on a different chain. You pay network gas on Cosmos Hub 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.
