Crate ckb_ssri_std

CKB SSRI std

Utils for implementing SSRI-compliant smart contracts on the Nervos CKB blockchain.

Overview

The SSRI (Standard Smart Contract Runtime Interface) std provides a standardized way to develop smart contracts that are compliant with the SSRI protocol. This enables better interoperability and a more consistent development experience across the CKB ecosystem.

Features

• Public Traits: Pre-defined interfaces that receive first-class support within the ecosystem
• Utility Functions: Helper functions for SSRI-VM syscalls and data handling
• Procedural Macros: Simplify contract development with automatic SSRI method generation
• No Standard Library: Designed for the constrained smart contract environment

Usage

Add this to your Cargo.toml:

[dependencies]
ckb-ssri-std = "0.1.0"

Example

use ckb_ssri_std::prelude::*;
use ckb_ssri_std::public_module_traits::udt::UDT;
 
// Implement a basic UDT (User-Defined Token)
#[derive(Default)]
struct MyToken;
 
impl UDT for MyToken {
    type Error = ();
    // ... implement required methods
}
