# Send IQDB to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

## Documentation

### Overview

Build on-chain relational databases on Solana using IQ Labs' tech stack. Three tools:

IQDB — Full CRUD relational database on Solana via Anchor PDAs. Tables, rows, rolling keccak hash for tamper-evident history.
hanLock — Password-based Hangul syllabic encoding (base-11172). Lightweight data encoding for on-chain privacy. Zero dependencies.
x402 — HTTP 402 payment-gated file inscription to Solana. Quote → Pay (USDC/SOL) → Broadcast chunk transactions → Download.

### Prerequisites

Node.js 18+
Solana CLI (solana --version)
A Solana wallet with devnet SOL (solana airdrop 2)

### Network Support

Mainnet: Fully supported. Program ID: 9KLLchQVJpGkw4jPuUmnvqESdR7mtNCYr3qS4iQLabs (via @iqlabs-official/solana-sdk).
Devnet: Supported via legacy SDK (@iqlabsteam/iqdb). Program: 7Vk5JJDxUBAaaAkpYQpWYCZNz4SVPm3mJFSxrBzTQuAX.

### Install (New Official SDK — recommended)

npm install @iqlabs-official/solana-sdk @solana/web3.js

### Install (Legacy SDK — devnet only)

npm install @iqlabsteam/iqdb @coral-xyz/anchor @solana/web3.js

### Environment Variables (Legacy SDK)

ANCHOR_WALLET=/path/to/keypair.json    # Required — Solana keypair for signing
ANCHOR_PROVIDER_URL=https://api.devnet.solana.com  # Required — RPC for writes
NETWORK_URL=https://api.devnet.solana.com  # Required — RPC for reads (must match ANCHOR_PROVIDER_URL)

Legacy SDK note: Set NETWORK_URL to match ANCHOR_PROVIDER_URL. The SDK uses separate connections for reads and writes.

RPC Note: Public Solana RPCs rate-limit aggressively. Add 2-3 second delays between rapid transactions on mainnet. Use a dedicated RPC provider (Helius, Alchemy, QuickNode) for production.

### Minimal Example — New SDK (Mainnet)

const { Connection, Keypair, SystemProgram, PublicKey } = require('@solana/web3.js');
const { writer, reader, setRpcUrl, contract } = require('@iqlabs-official/solana-sdk');

// Monkey-patch for Node v24 Buffer compatibility
const seedModule = require('@iqlabs-official/solana-sdk/dist/sdk/utils/seed');
const origFn = seedModule.toSeedBytes;
seedModule.toSeedBytes = (v) => Buffer.from(origFn(v));

setRpcUrl('https://api.mainnet-beta.solana.com');
const connection = new Connection('https://api.mainnet-beta.solana.com', 'confirmed');

// Write a row (requires root + table initialized first — see references/iqdb-core.md)
const sig = await writer.writeRow(
  connection, signer, 'my-db-root', 'players',
  JSON.stringify({ name: 'Alice', score: '1500', level: '12' })
);

// Read rows
const rows = await reader.readTableRows(tablePda);

### Minimal Example — Legacy SDK (Devnet)

// Use CommonJS — the SDK bundles CJS internally
const { createIQDB } = require('@iqlabsteam/iqdb');

const iqdb = createIQDB();

// Ensure root PDA exists (idempotent)
await iqdb.ensureRoot();

// Create a table (idempotent — use ensureTable over createTable)
await iqdb.ensureTable('players', ['name', 'score', 'level'], 'name');

// Write a row — data must be a JSON STRING, not an object
await iqdb.writeRow('players', JSON.stringify({
  name: 'Alice', score: '1500', level: '12'
}));

// Read all rows — requires userPubkey as string
const rows = await iqdb.readRowsByTable({
  userPubkey: 'YOUR_WALLET_PUBKEY',
  tableName: 'players'
});
console.log(rows);

### Architecture

Root PDA (per wallet)
  └── Table PDA (per table name)
       └── Rows stored as transaction data
            └── hash: keccak(domain || prev_hash || tx_data)

Root PDA — One per wallet. Initialized via ensureRoot().
Table PDA — Created via ensureTable() or createTable(). Has column schema and ID column.
Rows — Written as JSON strings via writeRow(). Append-only — each write is a new transaction.
Rolling hash — Each write appends to an immutable hash chain. Enables tamper detection without full replication.

### Core Operations

See references/iqdb-core.md for full API.

Cost reference (mainnet): Root + 3 tables + 5 data rows = ~0.09 SOL total.

### Important Constraints

Row data size limit: Keep row JSON under ~100 bytes. The on-chain program enforces a transaction size limit (TxTooLong error). For larger data, split across multiple rows or use hanLock sparingly (encoded output is larger than input).
Append-only writes: writeRow always appends. Use pushInstruction for updates/deletes.
pushInstruction writes to instruction log, not row data. readRowsByTable returns raw rows and does NOT reflect updates/deletes from pushInstruction. To see the full picture including corrections, use searchTableByName which returns both rows (raw) and instruRows/targetContent (instruction history). Your application must apply instruction corrections on top of raw rows.
CommonJS required: The SDK uses dynamic require() internally. Use .cjs files or "type": "commonjs" in package.json. ESM imports will fail.

### hanLock Encoding

See references/hanlock.md for full API.

Encode data with a password before writing on-chain for lightweight privacy:

const { encodeWithPassword, decodeWithPassword } = require('hanlock');

const encoded = encodeWithPassword('short secret', 'mypassword');
// → Korean syllable string like "깁닣뭡..."

// Write encoded data on-chain
await iqdb.writeRow('secrets', JSON.stringify({ owner: 'Alice', data: encoded }));

// Later — decode
const decoded = decodeWithPassword(encoded, 'mypassword');
// → 'short secret'

Note: hanLock encoding expands data size (~3x). Keep input short to stay within the on-chain row size limit.

### x402 Payment Flow

See references/x402-payments.md for full API.

Payment-gated file inscription to Solana:

Quote — POST /quote with file metadata → get price in USDC/SOL
Pay — Send payment transaction to provided address
Inscribe — POST /inscribe with payment proof → file chunked into Solana transactions
Download — GET /download/:txId → reconstruct file from on-chain chunks

### Use Cases

Discord RPG Bot — On-chain character persistence, provable item ownership, immutable game state
Governance — Tamper-evident proposal/vote storage with rolling hash audit trail
Compliance logs — Verifiable edit history for call center records
Paid storage — Monetize data inscription via x402
