Deploy contracts using Truffle
Please flow this document to clone and build
smartbchd. We need a test account and associated private key, smartbchd provides a sub-command to generate them for us:$ cd path/to/your/smartbch/dir # and build smartbchd following the given doc
$ ./smartbchd gen-test-keys -n 1 --show-address
The output looks like this (the generated private key and address are seperated by a space):
09c57df30208bdc056144c32d607f0719bdb0f8ac5f0a3259720d9e4d28d999b 0xab83b691Bc12Aae947B2ca240F1732fa792dE246
We need to install Node.js first, here are detailed information about how to install it on various platforms. Then, run the following cmd to install truffle:
$ npm install -g truffle
And run the following cmd the see if truffle was installed successfully:
$ truffle version
Truffle v5.1.63 (core: 5.1.63)
Solidity v0.5.16 (solc-js)
Node v15.10.0
Web3.js v1.2.9
Using
git clone cmd to clone pet-shop source code into you local directory:$ cd somedir
$ git clone https://github.com/trufflesuite/pet-shop-tutorial.git
$ cd pet-shop-tutorial
Install truffle hdwallet-provider v1.2.6 (for some unknown reason, the latest version v1.3.x may not work with private keys, so we use v1.2.x here):
$ npm install @truffle/[email protected] --save-dev
Modify truffle-config.js, add smartBCH testnet network configuration using you test key like bellow (you can find more smartBCH testnet RPC URLs here):
const HDWalletProvider = require('@truffle/hdwallet-provider');
module.exports = {
// See <http://truffleframework.com/docs/advanced/configuration>
// for more about customizing your Truffle configuration!
networks: {
development: {
host: "127.0.0.1",
port: 7545,
network_id: "*" // Match any network id
},
sbch_testnet: {
network_id: "10001",
gasPrice: 0,
provider: () => new HDWalletProvider({
providerOrUrl: "http://35.220.203.194:8545",
privateKeys: [
"09c57df30208bdc056144c32d607f0719bdb0f8ac5f0a3259720d9e4d28d999b",
],
}),
}
}
};
In directory pet-shop-tutorial, using
truffle migrate cmd to deploy Pet-Shop contract into smartBCH testnet:$ truffle migrate --network sbch_testnet
The output looks like this:
