Getting started takes a wallet and an address. The wallet needs to hold First Digital USD and a little FDUSD 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.
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 FDUSD, settling with settles with Ethereum blocks on ERC-20 on Ethereum (issuer: First Digital), 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 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.
Tokenized assets price from their issuer's own feed rather than a crypto market, so the quote tracks the underlying's session, and transfer eligibility follows the issuer's on-chain rules: the contract enforces them at settlement, which is why the checkout asks buyers to confirm eligibility once. These assets are not card-buyable; acquisition runs through the swap rail, and the fee structure above applies unchanged. What the wrapper adds is exposure with wallet speed, not brokerage machinery: no deposit account, no settlement lag between deciding and holding. Holders keep the same options as any token: send it, spend it where it is accepted, or swap back out the way they came in, and every movement carries the chain's own finality with it.
One signature, every venue compared, output to the wallet you choose.
