To deposit Bitcoin faster and with lower fees, you can use the Bitcoin Lightning Network. Lightning deposits use a Lightning invoice (not an on-chain BTC address). The addresses are generated in the BOLT11 format. Lightning invoice rules:
  • Each invoice is generated for a specific amount.
  • It can be paid only once.
  • It must be paid for the exact amount specified (no partial/overpayments).
  • It expires in 15 minutes.
To create a Lightning invoice, call /addresses/take, set currency to BTCLN, and include the amount parameter. The maximum supported amount is 0.045 BTCLN; for larger deposits, use the Bitcoin network.
Withdrawals via Lightning are not supported. If you need to withdraw, convert BTCLN to BTC (or another currency) first. Exchanges between BTCLN and BTC are always at a 1:1 rate with no fees.
