Swap USDC to Lightning

Paste an invoice or Lightning address. No account, no custody.

Lightning is the fastest way out of USDC. You paste a BOLT11 invoice or a Lightning address, send your USDC on Arbitrum, and the payment arrives in seconds once the deposit confirms.

There is no claim step for Lightning payouts: paying your invoice is the final action, so nothing is left for you to do afterwards.

USDC is sent from Arbitrum, the network with the deepest liquidity and the lowest gas of the chains we settle on.

How it works

  1. 1Enter an amount and paste a Lightning invoice or address.
  2. 2Your USDC is converted to tBTC and locked in the contract.
  3. 3We pay your invoice over Lightning.
  4. 4The payment settles in seconds. Nothing left to claim.

Questions

Can I use a Lightning address instead of an invoice?
Yes. An address like you@wallet.com works, and so does an LNURL. We request an invoice for the exact amount when the swap starts.
What if my invoice expires before I pay?
The swap is refunded once its timelock expires. You get tBTC on Arbitrum back, not USDC, because the conversion to tBTC happens before the funds are locked.
Is there a maximum amount?
Yes. Lightning payments are bounded by channel capacity, so the card shows the current minimum and maximum before you continue.
