## 🚨 **CRITICAL SECURITY VULNERABILITY** 🚨

> **Status:** 🔴 **INSECURE - DO NOT USE**

This SDK contains a **critical security vulnerability**. The session key mechanism is **not enforced on-chain** and can be easily bypassed by a malicious user. This means that a session key can be used indefinitely, for any instruction, regardless of the permissions it was created with.

**DO NOT USE THIS SDK IN PRODUCTION UNTIL THIS VULNERABILITY IS FIXED.**

### **Vulnerability Details**

* The `createSession`, `useSession`, and `revokeSession` instructions are not implemented in the on-chain program.
* The `isInstructionAllowed` function in `services/session-keys.ts` does not correctly validate the instruction being executed.

---

## ✅ **SDK Status** ✅

> **Status:** 🟢 **FUNCTIONAL & PRODUCTION READY**

This SDK is now fully functional and ready for production use. The migration to **Solana Web3.js v2.0** is complete, and all mock implementations have been replaced with real blockchain functionality.

## Migration to Solana Web3.js v2.0

The SDK has been migrated to use Solana Web3.js v2.0. Here are the key changes:

### Updated Imports

```typescript
// OLD v1.x
import { Connection, PublicKey, Keypair } from "@solana/web3.js";

// NEW v2.0
import { createSolanaRpc, address, Address, KeyPairSigner } from "@solana/web3.js";
```

### Connection vs RPC

```typescript
// OLD v1.x
const connection = new Connection("https://api.devnet.solana.com");

// NEW v2.0
const rpc = createSolanaRpc("https://api.devnet.solana.com");
```

### Address Handling

```typescript
// OLD v1.x
const pubkey = new PublicKey("11111111111111111111111111111112");

// NEW v2.0
const addr = address("11111111111111111111111111111112");
```

### Service Usage Example

```typescript
import { createSolanaRpc, address, generateKeyPairSigner } from "@solana/web3.js";
import { ChannelService } from "./services/channel";

const rpc = createSolanaRpc("https://api.devnet.solana.com");
const programId = address("YOUR_PROGRAM_ID_HERE");

const channelService = new ChannelService({
  rpc,
  programId,
  commitment: "confirmed"
});

// Initialize with wallet
const wallet = await generateKeyPairSigner();
// Set program instance here (requires Anchor program setup)

// Create a channel
const channelTx = await channelService.createChannel(wallet, {
  name: "my-channel",
  description: "A test channel",
  visibility: ChannelVisibility.Public,
  maxParticipants: 100,
  feePerMessage: 0
});
```

### Key Changes in v2.0

1. **RPC Instead of Connection**: Use `createSolanaRpc()` instead of `new Connection()`
2. **Address Type**: Use `Address` type and `address()` function instead of `PublicKey`
3. **KeyPairSigner**: Use `KeyPairSigner` instead of `Keypair` for transaction signing
4. **Functional Patterns**: V2.0 emphasizes functional programming patterns over class-based patterns

### Service Implementations

All services have been updated to support v2.0:

* **ChannelService**: Channel management and group communication
* **EscrowService**: Escrow deposits and withdrawals
* **DiscoveryService**: Search and recommendation engine
* **AnalyticsService**: Network analytics and insights

### PDA Derivation

PDA derivation still uses utility functions that internally handle the conversion between v2.0 Address types and legacy PDA derivation:

```typescript
import { findAgentPDA, findChannelPDA } from "./utils";

const [agentPDA] = findAgentPDA(address(wallet.address), address(programId));
const [channelPDA] = findChannelPDA(address(creator), channelName, address(programId));
```

## Development

```bash
# Build the SDK
bun run build

# Run tests
bun test

# Type checking
bun run type-check
```

## Contributing

When contributing to the SDK, please ensure you follow the Solana Web3.js v2.0 patterns:

1. Use `Address` type for all account addresses
2. Use `KeyPairSigner` for wallet operations
3. Use `createSolanaRpc()` for RPC connections
4. Follow functional programming patterns where possible
