Eth

[justinkook]

BWC/BWS eth changes with key class MR and also ETH bitcore-node module changes.

Now includes ETH insight changes.

Uses mainly crypto-wallet-core for eth functionality.

Copay Set Up

Bitcore

1. npm i in bitcore/ root directory.

2. rm -rf node_modules package-lock.json in bitcore/packages/bitcore-wallet-client/ directory.

This is to remove symlinks / lerna bootstrap npm packages inside bitcore-wallet-client.

3. npm i inside bitcore/packages/bitcore-wallet-client/ to install the NPM Registry versions of packages.

Copay

1. rm -rf node_modules package-lock.json inside copay/ to remove old versions of bitcore-wallet-client.

2. bash pack-all.sh inside copay/ to install local bitcore-wallet-client.

Status:

• Need to remove { fee: gasPrice } from util.buildTx and txproposal.buildTx once CWC fix is published to npm.

Requirements:

1. Parity dev chain:

--tracing on flag is required for internal contract transactions.

• https://wiki.parity.io/Setup

The following config flags are needed in the alias:

• alias parity-test="parity --config dev --jsonrpc-cors=all --ws-origins=all --ws-apis=all --tracing on --base-path '/Users/justin/blockchains/dev/'"

More information on parity config:

2. Add ETH to bitcore.config.json

"ETH": {
        "mainnet": {
          "provider": {
            "host": "127.0.0.1",
            "protocol": "ws",
            "port": 8546
          },
          "trustedPeers": [
            {
              "host": "127.0.0.1",
              "port": 30303
            }
          ]
        },

Steps to set up eth branch:

1. Make eth point to local bitcore-node.
   packages/bitcore-wallet-service/src/config.ts

eth: {
      livenet: {
        url: 'http://localhost:3000',
      },
      testnet: {
        url: 'http://localhost:3000',
      },

2. Point eth provider to local bitcore-node.
   packages/bitcore-wallet-service/src/lib/blockchainexplorer.ts

  eth: {
      livenet: 'http://localhost:3000',
      testnet: 'http://localhost:3000'
    }
