Features

• Translates reach contract handle to arc-4 interface description object.
• Supports readonly menthods.

Installation

Install with npm:

npm install ctc2abi

usage

Import the module and call the generateABI function with the reach contract handle as argument. The function returns a promise that resolves to the arc-4 interface description object.

Write interface description object to file

import * as backend from "./build/index.main.mjs";
import { generateABI } from "ctc2abi";
import { loadStdlib } from "@reach-sh/stdlib";
import fs from "fs";
const stdlib = loadStdlib(process.env);
const zeroAddress =
  "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY5HFKQ";
const accZero = await stdlib.connectAccount({ addr: zeroAddress });
const ctcZero = accZero.contract(backend);
const schema = await generateABI(ctcZero);
try {
  fs.writeFileSync("contract.json", JSON.stringify(schema));
  // file written successfully
} catch (err) {
  console.error(err);
}
//{
//  "name": "YourContractName",
//  "desc": "Description of your contract",
//  "methods": [
//    {
//      "name": "_reachp_0",
//      "args": [{ "type": "uint64" }, { "type": "(byte[67],address)" }],
//      "returns": { "type": "void" }
//    },
//    ...
