This is a plugin for eclair that implements the keysend
functionality. Keysend refers to sending payment without having a BOLT11 invoice at the recipient side, instead
using the new TLV format we can attach the payment preimage inside the innermost layer of the onion as a custom
TLV record. The receiver can accept the payment because it has the preimage from the TLV records. Please note that
the keysend functionality is non standard and still experimental.
This plugin has been tested with lnd-0.9.0-beta1.
The plugin can be built locally or downloaded from the release page of this repo, it's a fat jar that must be passed as argument to eclair when it's launched, see the instructions.
The plugin supprts both sending and receiving keysend payments, in order to send we expose a new http interface
with an additional endpoint:
| METHOD | Parameter (form_data) | Action | |
|---|---|---|---|
| /keysend | POST | amountMsat, nodeId, finalCltvExpiry(optional) | Send a keysend payment to the recipient |
Note that it's currently impossible for eclair plugins to add new HTTP-RPC endpoints, so this plugin listens
on a different port than the standard eclair API. You can configure the port by setting the
configuration key keysend.api.port but if none is set the plugin will default to the eclair API port + 1.
The same authentication credentials of the regular eclair API is necessary to use the plugin APIs.
