ERC20 Token Example

Token Example on Solana

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

Getting Started

First fetch the npm dependencies, including @solana/web3.js, by running:

$ npm install

Select a Network

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)

Run the test client

$ npm run start

Customizing the Program

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.
