Two things and you are ready. A wallet that can hold Arbitrum and a little ETH for gas on its chain, and the receiving address you want the output delivered to, which can be a raw address or a web3 name where the wallet resolves one. The preview shows the full picture before anything is signed: what leaves, what arrives, the fee, and the network cost. Nothing in the flow asks you to hand over keys; the wallet stays yours and signs only what you approved on screen.
Two costs, both visible up front. The platform charges a flat 0.50% all-in on the swap and nothing hidden behind it, no spread and no routing cut. The network charges its gas in ETH, settling with about 0.25 seconds blocks on Optimistic Rollup, itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of Credited after a few L2 confirmations, usually within seconds; settles to Ethereum L1 for finality., and once confirmed the balance is entirely yours to move with no platform anywhere in the path.
Underneath, the aggregated DEX route executes the trade with all-or-nothing semantics: partial fills do not exist here, and a route unable to meet the bounds you approved reverts the whole transaction rather than settling something worse. Your exposure window between legs is therefore zero, the only cost of a failed attempt is its gas, and re-quoting is a click.
Final, low-fee, borderless payments direct from your wallet to the merchant.
