(THIS BRANCH IS ONLY FOR TEST!) Polyjuice Http Provider

a godwoken-compatible http provider for web3.js.

now you can call your smart-contract on godwoken with metamask and eth address.

init web3

Before:

import Web3 from 'web3';

var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:8024'));

Now:

import Web3 from 'web3';
import PolyjuiceHttpProvider from './PolyjuiceHttpProvider';

var web3 = new Web3(new PolyjuiceHttpProvider('http://localhost:8024', GodwokenOption, ['your abi items array']));

for GodwokenOption: see here.

init contract instance

Before:

import Web3 from 'web3';

var provider = new Web3.providers.HttpProvider('http://localhost:8024');
var web3 = new Web3(provider);

var contract = web3.eth.Contract(abi, contract_address);

Now:

import Web3 from 'web3';
import PolyjuiceHttpProvider from './PolyjuiceHttpProvider';

var provider = new PolyjuiceHttpProvider('http://localhost:8024', GodwokenOption, ['your abi items array']);
var web3 = new Web3(provider);

var contract = web3.eth.Contract(abi, contract_address);

basically, PolyjuiceHttpProvider is just a extended class of [web3-providers-http]

const { PolyjuiceJsonRpcProvider } = require('PolyjuiceHttpProvider/lib/hardhat/providers');
const PolyjuiceWallet = require('PolyjuiceHttpProvider/lib/hardhat/wallet-signer');

before you can run test and an minimal example, create an .test.env file with some godwoken-polyjuice config.

cat > ./test.env <<EOF
WEB3_JSON_RPC=<godwoken web3 rpc>
ROLLUP_TYPE_HASH=<godwoken rollup type hash>
ETH_ACCOUNT_LOCK_CODE_HASH=<eth account lock code hash>
EXAMPLE_CONTRACT_ADDRESS=<an example test contract deployed address>
PRIVATE_KEY=<your eth test private key, do not use in production>

test

    yarn test
