AssemblyScript SDK

@infrix/sdk is the AssemblyScript SDK for authoring Infrix smart contracts in a TypeScript-like language that compiles to WebAssembly. Like the Rust SDK, contracts run inside the execution step of the governance spine.

Install

npm install @infrix/sdk

Write a contract

import { U256, Storage, Env } from "@infrix/sdk";

// Top-level functions become the WASM exports the runtime calls.
export function setValue(): void {
  // Every state write is captured as a StateChange on the spine.
  Storage.setU256("value", Env.value());
}

export function getValue(): U256 | null {
  return Storage.getU256("value");
}

Only top-level functions and constants become WASM exports — the value classes (U256, Address, Hash) and namespaces (Storage, Env, L0) are author-side surface you import, not module exports.

What it covers

• Value types: U256, Address, Hash
• Storage — typed contract state: get/set, getString/setString, getU256/setU256, has, remove, plus a StorageMap helper
• Env — execution context: caller(), owner(), value(), blockHeight(), txHash(), log(), require(), revert()
• L0 — Accumulate L0 access: getBalance(), transfer(), writeData()
• Governance — the governance bindings (exported first so tooling can lock ordering)
• Token ABIs: ACU20 / ACU721 selector + event constants

Build

npm run asbuild   # asc -> build/release.wasm (+ debug build)
