Getting started takes a wallet and an address. The wallet needs to hold Unichain and a little ETH for gas on its chain; the address is where the output lands, raw hex or a resolvable web3 name both work. From there the flow is preview-first: what leaves, what arrives, the fee, and the network cost all sit on one screen before a signature happens. Keys never leave your side at any point, and the only thing the wallet ever signs is the exact transaction you read.
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 1 sec blocks on Optimistic Rollup (OP Stack, Superchain), itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of Credited after L2 confirmation; deeper finality once the optimistic batch settles on Ethereum., 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.
