Two things and you are ready. A wallet that can hold Worldchain 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.
Count the costs on one hand. On the platform side a flat 0.50% covers the swap, all-in, stated in the quote with no spread or routing cut behind the number. On the network side, gas in ETH, settling with about 2 sec blocks on Optimistic Rollup (OP Stack, Superchain), shown per leg before signature. Settlement runs on-chain to your chosen address at this asset's policy, Credited after L2 confirmation; deeper finality once the optimistic batch settles on Ethereum., and from confirmation onward the balance answers to your keys alone, spendable, sendable, and settled with no platform anywhere in the path.
The route runs on the aggregated DEX route, and atomicity is the property that matters: the approved number either happens in full or the transaction reverts with nothing moved but the attempt's gas. There is no resting state between legs where value sits in someone else's hands, and a route that misses your bounds simply fails clean, ready for a fresh quote. Cheap and loud beats silent and expensive as failure modes go.
