The setup is deliberately short. One wallet capable of holding Base and a little ETH for gas on its chain, one receiving address for the output, and you have everything: a web3 name resolves to the address just as well as the raw string. Read the preview before signing, since it carries the whole trade at a glance, the amounts in and out, the fee, and the network cost. The wallet remains yours throughout and signs nothing you have not seen on screen, which is the whole security posture in one sentence.
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 2 seconds blocks on Optimistic Rollup (OP Stack), 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, typically under a minute; deeper finality on Ethereum L1., and once confirmed the balance is entirely yours to move with no platform anywhere in the path.
Execution runs through the aggregated DEX route, which means the number you approved is the number that happens or the transaction reverts: swaps are atomic, with no half-settled state to unwind and no exposure window between legs. If a route cannot fill at your approved bounds it fails cleanly and you re-quote, which is the failure mode you want, cheap and loud rather than silent and expensive.
Final, low-fee, borderless payments direct from your wallet to the merchant.
