Methods
GetInfo
Gets general information about the daemon like the chain of the lightning node it is connected to and the IDs of pending swaps.
GetServiceInfo
Fetches the latest limits and fees from the Boltz backend API it is connected to.
GetPairInfo
Fetches information about a specific pair for a chain swap.
GetPairs
Fetches all available pairs for submarine and reverse swaps.
ListSwaps
Returns a list of all swaps, reverse swaps, and chain swaps in the database.
GetStats
Returns stats of all swaps, reverse swaps, and chain swaps in the database.
RefundSwap
Refund a failed swap manually. This is only required when no refund address has been set and the swap does not have an associated wallet.
ClaimSwaps
Claim swaps manually. This is only required when no claim address has been set and the swap does not have an associated wallet.
GetSwapInfo
Gets all available information about a swap from the database.
GetSwapInfoStream
Returns the entire history of the swap if is still pending and streams updates in real time. If the swap id is empty or "*" updates for all swaps will be streamed.
Deposit
This is a wrapper for channel creation swaps. The daemon only returns the ID, timeout block height and lockup address. The Boltz backend takes care of the rest. When an amount of onchain coins that is in the limits is sent to the address before the timeout block height, the daemon creates a new lightning invoice, sends it to the Boltz backend which will try to pay it and if that is not possible, create a new channel to make the swap succeed.
CreateSwap
Creates a new swap from onchain to lightning.
CreateChannel
Create a new swap from onchain to a new lightning channel. The daemon will only accept the invoice payment if the HTLCs is coming trough a new channel channel opened by Boltz.
CreateReverseSwap
Creates a new reverse swap from lightning to onchain. If accept_zero_conf is set to true in the request, the daemon will not wait until the lockup transaction from Boltz is confirmed in a block, but will claim it instantly.
CreateChainSwap
Creates a new chain swap from one chain to another. If accept_zero_conf is set to true in the request, the daemon will not wait until the lockup transaction from Boltz is confirmed in a block, but will claim it instantly.
CreateWallet
Creates a new liquid wallet and returns the mnemonic.
ImportWallet
Imports an existing wallet.
SetSubaccount
Sets the subaccount of a wallet. Not supported for readonly wallets.
GetSubaccounts
Returns all subaccounts for a given wallet. Not supported for readonly wallets.
GetWallets
Returns all available wallets.
GetWallet
Returns the current balance and subaccount of a wallet.
GetWalletSendFee
Calculates the fee for an equivalent WalletSend request. If address is left empty, a dummy swap address will be used, allowing for a fee estimation of a swap lockup transaction.
ListWalletTransactions
Returns recent transactions from a wallet.
GetWalletCredentials
Returns the credentials of a wallet. The password will be required if the wallet is encrypted.
RemoveWallet
Removes a wallet.
WalletSend
Send coins from a wallet. Only the confirmed balance can be spent.
WalletReceive
Get a new address of the wallet.
Stop
Gracefully stops the daemon.
Unlock
Unlocks the server. This will be required on startup if there are any encrypted wallets.
VerifyWalletPassword
Check if the password is correct.
ChangeWalletPassword
Changes the password for wallet encryption.
CreateTenant
Creates a new tenant which can be used to bake restricted macaroons.
ListTenants
Returns all tenants.
GetTenant
Get a specifiy tenant.
BakeMacaroon
Bakes a new macaroon with the specified permissions. The macaroon can also be restricted to a specific tenant. In this case, - any swap or wallet created with the returned macaroon will belong to this tenant and can not be accessed by other tenants. - the lightning node connected to the daemon can not be used to pay or create invoices for swaps.
