Easily write and interact with Bitcoin Cash contracts
npm install @sahidmiller/cashscript!Build Status




CashScript is a high-level programming language for smart contracts on Bitcoin Cash. It offers a strong abstraction layer over Bitcoin Cash' native virtual machine, Bitcoin Script. Its syntax is based on Ethereum's smart contract language Solidity, but its functionality is very different since smart contracts on Bitcoin Cash differ greatly from smart contracts on Ethereum. For a detailed comparison of them, refer to the blog post Smart Contracts on Ethereum, Bitcoin and Bitcoin Cash.
See the GitHub repository and the CashScript website for full documentation and usage examples.
.json artifact files that were compiled using the cashc compiler and convert them to Contract objects. These objects are used to create new contract instances. These instances are used to interact with the contracts using the functions that were implemented in the .cash file. For more information on the CashScript SDK, refer to the SDK documentation.bash
npm install cashscript
`$3
`ts
import { Contract, ... } from 'cashscript';
`Using the CashScript SDK, you can import contract artifact files, create new instances of these contracts, and interact with these instances:
`ts
...
// Import the P2PKH artifact
import P2PKH from './p2pkh-artifact.json' assert { type: 'json' }; // Instantiate a network provider for CashScript's network operations
const provider = new ElectrumNetworkProvider('mainnet');
// Create a new P2PKH contract with constructor arguments: { pkh: pkh }
const contract = new Contract(P2PKH, [pkh], provider);
// Get contract balance & output address + balance
console.log('contract address:', contract.address);
console.log('contract balance:', await contract.getBalance());
// Call the spend function with the owner's signature
// And use it to send 0. 000 100 00 BCH back to the contract's address
const txDetails = await contract.functions
.spend(pk, new SignatureTemplate(keypair))
.to(contract.address, 10000)
.send();
console.log(txDetails);
