Getting started takes a wallet and an address. The wallet needs to hold Polkadot and a little DOT 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.
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 DOT, settling with about 6 sec blocks on Nominated Proof-of-Stake, shown per leg before signature. Settlement runs on-chain to your chosen address at this asset's policy, 1 block (fast), a few extra for high value, and from confirmation onward the balance answers to your keys alone, spendable, sendable, and settled with no platform anywhere in the path.
Execution runs through an instant integration, 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.
