Getting started takes a wallet and an address. The wallet needs to hold Linea 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.
The cost picture is two lines. The platform side is a flat 0.50% all-in on the swap, quoted before you sign, with no spread and no routing cut behind it. The network side is gas paid in ETH, settling with about 1 sec blocks on ZK Rollup (settles to Ethereum), which the preview itemizes per leg. Settlement is on-chain to the address you chose: Credited once the L2 transaction is confirmed; deeper finality when the zk-proof settles on Ethereum. on this asset, after which the balance is spendable and non-custodial in the fullest sense, yours to move with no platform 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.
