Before you start

The setup is deliberately short. One wallet capable of holding Coinbase 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.

Fees and settlement

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 ETH, settling with about 250 ms blocks on Arbitrum Orbit L2, which the preview itemizes per leg. Settlement is on-chain to the address you chose: 3 confirmations (fast L2 finality) 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.

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.
