This project demonstrates how to use the Solana Javascript API to build, deploy, and interact with an ERC20-like Token example program on the Solana blockchain.
The project comprises of:
- A library to interact with the on-chain program
- Test client that exercises the program
First fetch the npm dependencies, including @solana/web3.js
, by running:
$ npm install
This example connects to a local Solana cluster by default.
To enable on-chain program logs, set the RUST_LOG
environment variable:
$ export RUST_LOG=solana_runtime::native_loader=trace,solana_runtime::system_instruction_processor=trace,solana_runtime::bank=debug,solana_bpf_loader=debug,solana_rbpf=debug
To start a local Solana cluster run:
$ npm run localnet:update
$ npm run localnet:up
Solana cluster logs are available with:
$ npm run localnet:logs
For more details on working with a local cluster, see the full instructions.
By default the program will connect to the beta testnet. To use the edge testnet instead, define `export CHANNEL=edge' in your environment (see url.js for more)
$ npm run start
To customize the example, make changes to the files under /src
Now when you run npm run start
, you should see the results of your changes.
