Lightning Latch example

To perform an lightning latch swap of a mercurylayer coins and a lightning network payment, first create two separate wallets:

cargo run create-wallet wallet1
cargo run create-wallet wallet2

Generate a new deposit token:

cargo run new-token

cargo run cargo run new-deposit-address wallet1 <token> 100000

Deposit signet bitcoin to the generated address and wait for coin status getting CONFIRMED, then:

cargo run list-statecoins wallet1 

Coin receiver generates a transfer address for wallet2 and sends tothe coin sender.

cargo run new-transfer-address wallet2 -b

Coin sender generate a payment hash and batch_id from the mercury server using the statechain ID of the coin being swaped:

cargo run payment-hash wallet1 <statechain_id>

The sender then generates a Lightning invoice using the payment hash (e.g. using the AddHoldInvoice RPC function in LND).

The sender then performs transfer-sender with the batch_id:

cargo run transfer-sender wallet1 <statechain_id> <transfer-address> <batch_id>

The reciver then performes transfer-reciever to confirm coin validity and the coin is bacth-locked.

cargo run transfer-reciever wallet2

The sender gives the invoice and to the coin receiver to pay.

The reciever pays the HOLD-invoice.

The sender confirms the HOLD-invoice is pending (e.g. using the LookupInvoiceV2 RPC function in LND).

The sender then unlocks the coin:

cargo run confirm-pending-invoice wallet1 <statechain_id>

The reciver can now complete the transfer-reciver function.

The sender can now retrie the hash pre-image to complete the lightning payment using:

cargo run retrieve-preimage wallet1 <statechain_id> <batch_id>

And then recieve the payment with LND command SettleInvoice.
