Worldcoin (WLD) is the token of the World Chain ecosystem, distributed to people verified by the World ID iris-scan protocol and used for governance and incentives across World apps. On U.CASH, WLD sits in the partner-rail tier: buy it with card or bank and sell it back to fiat through the on-ramp network, delivered to your own wallet on Ethereum. World Chain itself is one of the 34 U.CASH networks with its own page. Availability of the WLD rails varies by provider and region.

Two things and you are ready. A wallet that can hold Worldcoin and a little WLD for gas on its chain, and the receiving address you want the output delivered to, which can be a raw address or a web3 name where the wallet resolves one. The preview shows the full picture before anything is signed: what leaves, what arrives, the fee, and the network cost. Nothing in the flow asks you to hand over keys; the wallet stays yours and signs only what you approved on screen.
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 WLD, settling with settles with Ethereum blocks on ERC-20 on Ethereum (World Chain ecosystem), itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of Follows Ethereum (~12 confirmations), and once confirmed the balance is entirely yours to move with no platform anywhere in the path.
Underneath, the swap engine 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.
