Nigiri chopsticks

This is an API passthrough that simply proxies requests to the underlying services. It expects an electrum REST server and an optional RPC server for faucet and custom broadcasting services.

Usage

Clone the repo:

$ git clone [email protected]:vulpmeventures/nigiri-chopsticks.git

Run tests:

$ bash scripts/test local

To run tests locally you must have a running Nigiri instance.

Build for Linux x64:

nigiri-chopsticks $ bash scripts/build linux amd64

Build for Mac:

nigiri-chopsticks $ bash scripts/build darwin amd64

Run:

nigiri-chopsticks $ ./build/nigiri-chopsticks-darwin-amd64

Routes and Customization

The web server starts at default address localhost:3000 with the following routes:

• /faucet if faucet is enabled, to send funds to an address
  • example for Bitcoin:

  $ curl -X POST --data '{"address": "2MsnWskyHaHvcZUHA4gnR3G95EnUmZQjzM8", "amount": 0.02}' http://localhost:3000/faucet

  • example for Liquid

  $ curl -X POST --data '{"address": "2MsnWskyHaHvcZUHA4gnR3G95EnUmZQjzM8", "asset": "2dcf5a8834645654911964ec3602426fd3b9b4017554d3f9c19403e7fc1411d3", "amount": 0.02}' http://localhost:3000/faucet

• /mint (only for Liquid chain) if faucet is enabled, to issue an asset and sent all issuance amount to an address
  • example:

  $ curl -X POST --data '{"address": "ert1q90dz89u8eudeswzynl3p2jke564ejc2cnfcwuq", "quantity": 1000, "name": "TokenName", "ticker":"TKN"}' http://localhost:3000/mint

• /registry (only for Liquid chain) if faucet is enabled, to get extra info about one or more assets like name and ticker

  $ curl -X POST --data '{"assets": ["2dcf5a8834645654911964ec3602426fd3b9b4017554d3f9c19403e7fc1411d3"]}' http://localhost:3000/registry
  # [{"asset":"2dcf5a8834645654911964ec3602426fd3b9b4017554d3f9c19403e7fc1411d3","contract":{"name":"test","ticker":"TST"},"issuance_txin":{"txid":"a0891447adb288e5a49fa10ede7016788a1b3a175cfb423eb133e45f6cefca84","vin":0},"name":"test","ticker":"TST"

• all esplora HTTP API endpoints

Note:
If mining is enabled, the esplora broadcast endpoint is wrapped so that a block is mined just after the transaction is published to get it confirmed; this is useful when running in regtest network.
All requests to chopsticks are (optionally) logged using a logger inspired by negroni package.

To customize server urls and ports use flags when running the binary:

• --chain one between bitcoin and liquid
• --addr server listening address (default localhost:3000)
• --rpc-addr btc RPC server listening address (default localhost:19001)
• --btc-cookie btc RPC server user and password (default admin1:123)
• --liquid-addr liquid RPC server listening address (default localhost:18884)
• --electrs-addr electrs HTTP server listening address (default localhost:3002)
• --use-tls specify using either http or https (default true)
• --use-faucet to have a /faucet endpoint available for sending funds
• --use-mining to have the esplora /broadcast endpoint wrapped so that a block is mined after the transaction is published
• --use-logger to log every request/response
• --registry-path to set the path for the asset registry db (default to current directory - Liquid only)
