Smart Contract Generator

Smart Contract Generator

Generate production-ready Solidity smart contracts from natural language descriptions. Powered by the same streaming endpoint as the LLM chatbot, using a specialized model fine-tuned for smart contract generation.

Key Facts

Endpoint	POST /chat/stream
Model	smart_contract_generator
Cost	1 credit per request (2 with chat history enabled)
SDK	@chaingpt/smartcontractgenerator
Output	Solidity source code

Parameters

Parameter	Type	Required	Description
model	string	Yes	Must be "smart_contract_generator"
question	string	Yes	Natural language description of the contract you want
chatHistory	string	No	"on" or "off" (string, not boolean). Enables iterative refinement. Doubles cost to 2 credits. Default: "off"
sdkUniqueId	string	No	Unique session identifier for maintaining conversation context

Quick Start -- JavaScript

npm install @chaingpt/smartcontractgenerator

import { SmartContractGenerator } from "@chaingpt/smartcontractgenerator";

const client = new SmartContractGenerator({
  apiKey: process.env.CHAINGPT_API_KEY,
});

const response = await client.createChatMessage({
  model: "smart_contract_generator",
  question:
    "Create an ERC-721 NFT contract with a max supply of 10,000, " +
    "0.05 ETH mint price, and an owner-only withdraw function. " +
    "Include a merkle proof whitelist for presale.",
  chatHistory: "off",
});

console.log(response.data.bot);

Iterative Refinement with Chat History

// First request: generate the base contract
const base = await client.createChatMessage({
  model: "smart_contract_generator",
  question: "Create a simple ERC-20 token with 1 billion supply and 2% burn on transfer",
  chatHistory: "on",
  sdkUniqueId: "session-contract-001",
});

console.log(base.data.bot);

// Follow-up: modify the contract
const revised = await client.createChatMessage({
  model: "smart_contract_generator",
  question: "Add a 1% reflection mechanism and an anti-whale max transaction limit of 1%",
  chatHistory: "on",
  sdkUniqueId: "session-contract-001",
});

console.log(revised.data.bot);

Tips

• Be specific in your descriptions -- include token standards (ERC-20, ERC-721, ERC-1155), access control requirements, and any special mechanisms.
• Use chat history for iterative refinement: generate a base contract, then request modifications in follow-up messages.
• Always pipe the generated output into the Smart Contract Auditor before deploying. The Generator + Auditor combo is the most natural pairing in the suite.
• For offline or self-hosted Solidity generation, see the Solidity LLM.
