The setup is deliberately short. One wallet capable of holding Sandisk 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.
Count the costs on one hand. On the platform side a flat 0.50% covers the swap, all-in, stated in the quote with no spread or routing cut behind the number. On the network side, gas in ETH, settling with about 2 s blocks on OP Stack L2, shown per leg before signature. Settlement runs on-chain to your chosen address at this asset's policy, 3 confirmations (fast L2 finality), and from confirmation onward the balance answers to your keys alone, spendable, sendable, and settled with no platform anywhere 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.
