sidechain atomic swap connector

middleware-eth-sidechain

Middleware service for which transfer token from mainnet to sidechain and revert

Installation

This module is a part of middleware services. You can install it in 2 ways:

1. through core middleware installer middleware installer
2. by hands: just clone the repo, do 'npm install', set your .env - and you are ready to go

About

This module is used for interaction with middleware. This happens through the layer, which is built on node-red. So, you don't need to write any code - you can create your own flow with UI tool supplied by node-red itself. Access by this route:

/admin

Predefined Routes with node-red flows

The available routes are listed below:

route	methods	params	description
/mainnet/swaps/:address	GET	{address: <string>}	get list swaps in mainnet(transfer from mainnet to sidechain) for selected address, select only open by field isActive, Output: [ swap_id: {Number}, isActive: {Boolean}, created: {UnixTimestamp} ]
/mainnet/swap/obtain/:id	GET	{id: <Number>}	get secret key by id swap in mainnet, get in encypt form by public key user, Output [ encrypt secret key by pubkey user]
/sidechain/swaps/:address	GET	{address: <string>}	get list swaps in sidechain for selected address, select only open by field isActive, Output: [ swap_id: {Number}, isActive: {Boolean}, created: {UnixTimestamp} ]
/sidehcain/swap/obtain/:id	GET	{id: <Number>}	get secret key by id swap in sidechain, get in encypt form by public key user, Output [ encrypt secret key by pubkey user]
