IQ SDK

This SDK provides a simple interface to inscribe, read, and validate data on-chain using the IQ6900 protocol.

---

Features

• Inscribe data (codeIn, codeInAfterErr)
• Fetch data (readCode, fetchLargeFileAndDoCache)
• Validate local data against on-chain state (dataValidation)
• Account initialization helper (user_init)

---

Setup

Install from GitHub

npm install https://github.com/IQ6900/code_in_sdk.git

---

Environment variables (.env)

Before using the SDK, create a .env file at your project root:

SIGNER_PRIVATE_KEY="your_base58_encoded_private_key"
RPC="https://your.solana.rpc.endpoint"

---

Build (only if using source directly)

If you cloned the repository directly:

npm run build

Usage Guide

Account initialization (required on first use per wallet)

Before writing data for a wallet, you must initialize the user account on-chain:

import iqsdk from 'iq-sdk';

await iqsdk.userInit();

---

Write data to chain

import iqsdk from 'iq-sdk';


await iqsdk.codeIn("your data here", "manual_datatype", "your_handle");

---

Fetch data from chain

import iqsdk from 'iq-sdk';

const result = await iqsdk.readCode("your_transaction_id");

Or fetch and cache large files:

import iqsdk from 'iq-sdk';

const content = await iqsdk.fetchLargeFileAndDoCache("your_transaction_id");

---

Validate local data

import iqsdk from 'iq-sdk';

await iqsdk.dataValidation("transaction_id", "localDataString");
