Before you start

The setup is deliberately short. One wallet capable of holding Sirius XM 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

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 250 ms blocks on Arbitrum Orbit L2, itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of 3 confirmations (fast L2 finality), 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.

Sirius XM: FAQ

What is a SIRIx tokenized asset?
It is an ERC-20 token on Robinhood Chain that tracks the underlying Sirius XM share and is transferable under the issuer's on-chain rules.
Can anyone hold SIRIx?
The token contracts enforce their own transfer compliance: transfers to or from addresses the issuer blocks revert on-chain, and the issuer can pause a token. Checkouts ask buyers to confirm they are eligible to hold tokenized assets under their local rules.
How is the SIRIx price determined?
U.CASH reads the issuer's price feed (bid/ask mid with the current token-per-share multiplier) rather than a crypto market feed, refreshing every few minutes.

Open swap.u.cash with SIRIx preselected as the asset you receive: swap any crypto you hold for it in one signed transaction on BNB Chain. It settles straight to your wallet.
What ISIN does the SIRIx token track?
The Sirius XM tokenized asset carries ISIN CH1588662077 (issuer: Sirius XM xStock). On U.CASH the price comes from the token's own feed, not a crypto market.
