USD Coin (USDC) is a fully-reserved US-dollar stablecoin, with one USDC designed to track one US dollar. It is issued across several EVM chains, including Ethereum, Base, and Polygon, and is a staple of payments and DeFi.

Two things and you are ready. A wallet that can hold USD Coin and a little USDC 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.
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 USDC, settling with settles with the host chain blocks on Multi-chain token (ERC-20), which the preview itemizes per leg. Settlement is on-chain to the address you chose: Follows the host chain (Ethereum ~12, Base ~a few, Polygon ~a few) 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.
The route runs on the aggregated DEX route, and atomicity is the property that matters: the approved number either happens in full or the transaction reverts with nothing moved but the attempt's gas. There is no resting state between legs where value sits in someone else's hands, and a route that misses your bounds simply fails clean, ready for a fresh quote. Cheap and loud beats silent and expensive as failure modes go.
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 account unlocks accept, swap, buy, and the rest of the U.CASH network across 35 networks.
