Pool gRPC API Reference

Welcome to the gRPC API reference documentation for Lightning Pool.

Lightning Pool is a non-custodial batched uniform clearing-price auction for Lightning Channel Lease (LCL). A LCL packages up inbound (or outbound!) channel liquidity (ability to send/receive funds) as a fixed incoming asset (earning interest over time) with a maturity date expressed in blocks. The maturity date of each of the channels is enforced by Bitcoin contracts, ensuring that the funds of the maker (the party that sold the channel) can't be swept until the maturity height. All cleared orders (purchased channels) are cleared in a single batched on-chain transaction.

This repository is home to the Pool client and depends on the Lightning Network daemon lnd. All of lnd’s supported chain backends are fully supported when using the Pool client: Neutrino, Bitcoin Core, and btcd.

The service can be used in various situations:

• Bootstrapping new users with side car channels
• Bootstrapping new services to Lightning
• Demand fueled routing node channel selection
• Allowing users to instantly receive with a wallet

This site features the documentation for pool (CLI), and the API documentation for Python and JavaScript clients in order to communicate with a local poold instance through gRPC. Currently, this communication is unauthenticated, so exposing this service to the internet is not recommended.

The original *.proto files from which the gRPC documentation was generated can be found here:

• auctioneerrpc/auctioneer.proto
• poolrpc/trader.proto

This is the reference for the gRPC API. Alternatively, there is also a REST API which is documented here.

This documentation was generated automatically against commit 76006c565ef860b1d915c80574680a4ff92866c5.

rejected_orders	array RejectedOrdersEntry	The map of order nonces the trader was matched with but doesn't accept. The map contains the other trader's order nonces and the reason for rejecting them. This can be a subset of the whole list of orders presented as matches if the trader only wants to reject some of them. This map is only considered by the auctioneer if the main reason_code is set to PARTIAL_REJECT. Otherwise it is assumed that the whole batch was faulty for some reason and that the trader rejects all orders contained. The auctioneer will only accept a certain number of these partial rejects before a trader's account is removed completely from the current batch. Abusing this functionality can also lead to a ban of the trader. The order nonces are hex encoded strings because the protobuf map doesn't allow raw bytes to be the map key type.

Pool REST API Reference

Welcome to the REST API reference documentation for Lightning Pool.

Lightning Pool is a non-custodial batched uniform clearing-price auction for Lightning Channel Lease (LCL). A LCL packages up inbound (or outbound!) channel liquidity (ability to send/receive funds) as a fixed incoming asset (earning interest over time) with a maturity date expressed in blocks. The maturity date of each of the channels is enforced by Bitcoin contracts, ensuring that the funds of the maker (the party that sold the channel) can't be swept until the maturity height. All cleared orders (purchased channels) are cleared in a single batched on-chain transaction.

This repository is home to the Pool client and depends on the Lightning Network daemon lnd. All of lnd’s supported chain backends are fully supported when using the Pool client: Neutrino, Bitcoin Core, and btcd.

The service can be used in various situations:

• Bootstrapping new users with side car channels
• Bootstrapping new services to Lightning
• Demand fueled routing node channel selection
• Allowing users to instantly receive with a wallet

This site features the API documentation for shell script (CLI), Python and JavaScript clients in order to communicate with a local poold instance through gRPC. Currently, this communication is unauthenticated, so exposing this service to the internet is not recommended.

The original *.swagger.js files from which the gRPC documentation was generated can be found here:

• poolrpc/trader.swagger.json

NOTE: The byte field type must be set as the base64 encoded string representation of a raw byte array. Also, any time this must be used in a URL path (ie. /v1/abc/xyz/{payment_hash}) the base64 string must be encoded using a URL and Filename Safe Alphabet. This means you must replace + with -, / with _, and keep the trailing = as is. Url encoding (ie. %2F) will not work.

This is the reference for the REST API. Alternatively, there is also a gRPC API which is documented here.

This documentation was generated automatically against commit 76006c565ef860b1d915c80574680a4ff92866c5.

POST /v1/pool/accounts/bump

pool: accounts bumpfee BumpAccountFee attempts to bump the fee of an account's transaction through child-pays-for-parent (CPFP). Since the CPFP is performed through the backing lnd node, the account transaction must contain an output under its control for a successful bump. If a CPFP has already been performed for an account, and this RPC is invoked again, then a replacing transaction (RBF) of the child will be broadcast.

Field	Type	Placement	Description
trader_key	byte	body	The trader key associated with the account that will have its fee bumped.
fee_rate_sat_per_kw	string	body	The new fee rate, in satoshis per kw, to use for the child of the account transaction.
