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. On Arbitrum, USDC moves as a ERC-20 token: transfers pay Arbitrum network fees in ETH and settle with the network's own finality. Every U.CASH rail that runs on Arbitrum, from checkout to swap, supports USDC natively on this chain.
USDC transfers confirm with the Arbitrum network (~0.25 seconds blocks). Settlement on U.CASH is non-custodial: every payment and swap moves on-chain, direct to a wallet you control.
Every action opens with USDC already selected.

The setup is deliberately short. One wallet capable of holding USD Coin on Arbitrum and a little ETH 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.
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 ETH, settling with about 0.25 seconds blocks on Optimistic Rollup, itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of USDC transfers confirm with the Arbitrum network (~0.25 seconds blocks), and once confirmed the balance is entirely yours to move with no platform anywhere in the path.
Execution runs through the aggregated DEX route, 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.
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.
Swap, buy, and settle USDC on Arbitrum non-custodial, straight to the wallet you control.
