Before you start

Getting started takes a wallet and an address. The wallet needs to hold Chainlink and a little LINK 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.

Fees and settlement

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 LINK, settling with settles with Ethereum blocks on ERC-20 token on Ethereum, which the preview itemizes per leg. Settlement is on-chain to the address you chose: Follows Ethereum (~12 confirmations) 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.

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.
