README

tx-forwarder

Server that forwards the tx to the specified smart contract.

Usage

In production use ./tx-forwarder, in development use go run main.go in order to make sure to be running last @master version.

Config

Deploy needed smart contracts, each one of the commands, will return the contract deployed address, that will be needed to be placed in the config.yaml.

./tx-forwarder deploy mimc7
./tx-forwarder deploy rootcommits
./tx-forwarder deploy whitelist
./tx-forwarder deploy zkpverifier
./tx-forwarder deploy disableid

This will print the deployed contract address, then copy&paste in the config file config.yaml:

server:
        serviceapi: 0.0.0.0:11000
        adminapi: 0.0.0.0:11001
web3:
        url: http://127.0.0.1:8545
keystore:
        path: /var/config/keystore
        address: 0x123456789...
        passwd: /var/config/keystore.password
        keyjsonpath: /var/config/keystore/UTC-etc
contracts:
        samplecontract: 0xasdf
        mimc7contract: 0xasdf
        rootcommitscontract: 0xasdf
        whitelistcontract: 0xasdf
        zkpverifiercontract: 0xasdf
        disableidcontract: 0xasdf

Run

Then, run the server:

./tx-forwarder start

Also can info can be getted by running:

./tx-forwarder info

Contract

Current contract is just a working sample contract.

The contract handlers goes inside eth/contract/ directory.

Once having the contract file written in Solidity, in order to generate the Go handlers:

solc --abi --bin SampleContract.sol -o build
abigen --bin=./build/SampleContract.bin --abi=./build/SampleContract.abi --pkg=SampleContract --out=SampleContract.go

// or directly (use this one)
abigen --sol SampleContract.sol --pkg SampleContract --out=SampleContract.go

And place the sampleContract.go file in the eth/contract/sampleContract.go path.
