How do I buy an item that is on another chain?

You do not need to bridge funds yourself. On the purchase or mint sheet choose Pay from another chain:

1. Pick the payment network where you hold funds, and whether to pay in USDC or in that network's gas token.
2. Review the fee breakdown, which includes the cross-chain payment provider's fee.
3. Confirm once in your wallet.

Payment goes through the universal account linked to your wallet (provided by Particle Network), is delivered to the item's chain, and the purchase or mint executes there. The item arrives in your wallet address on the item's chain, so make sure your wallet can see that network.

If the purchase cannot complete — for example the listing was filled first — use Get my funds back on the transaction status view. Funds return to your universal account or wallet on the payment network, less network costs already spent. Unvault does not hold the funds at any point.
