Important

p-token codebase moved to SPL Token repository.

p-token

A pinocchio-based Token program.

Overview

This repository contains a proof-of-concept of a reimplementation of the SPL Token program, one of the most used programs on Solana, using pinocchio. The purpose is to have an implementation that optimizes the compute units, while being fully compatible with the original implementation — i.e., support the exact same instruction and account layouts as SPL Token, byte for byte.

Features

• no_std crate
• Same instruction and account layout as SPL Token
• Minimal CU usage

Status

• Account and Mint
• Instructions
• Basic instruction tests
• Existing SPL Token tests

Tests were run using Solana v2.1.0.

Building

To build the programs from the root directory of the repository:

pnpm install

to install the required libraries, then:

pnpm programs:build

Testing

To run the tests against both versions of the Token program:

pnpm programs:test
