The setup is deliberately short. One wallet capable of holding Polygon and a little POL for gas on its chain, one receiving address for the output, and you have everything: a web3 name resolves to the address just as well as the raw string. Read the preview before signing, since it carries the whole trade at a glance, the amounts in and out, the fee, and the network cost. The wallet remains yours throughout and signs nothing you have not seen on screen, which is the whole security posture in one sentence.
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 POL, settling with about 2 seconds blocks on Proof-of-Stake, which the preview itemizes per leg. Settlement is on-chain to the address you chose: Credited after a few PoS confirmations, usually within a minute. 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.
One account unlocks accept, swap, buy, and the rest of the U.CASH network across 35 networks.
