Eliza OTC Desk

Multi-chain AI-powered OTC trading desk with Eliza agent. Supports Jeju, Base, BSC, and Solana with full localnet E2E testing.

✅ Hardhat → Anvil Migration Complete

This project now uses Foundry/Anvil instead of Hardhat:

• ✅ Faster compilation (10-50x faster with Forge)
• ✅ Native fuzz testing and gas snapshots
• ✅ Simpler setup (no node_modules for contracts)
• ✅ Industry-standard Solidity toolchain
• ✅ All tests migrated to use Anvil (chain ID 31337)

All references to Hardhat have been replaced with Anvil. See contracts directory for Foundry configuration.

Features

• 🤖 AI Agent - Eliza negotiates deals with users
• ⛓️ Multi-Chain - Jeju (default), Base, BSC, Solana
• 🧪 Real E2E Tests - Deploys contracts, creates offers, verifies state (NO MOCKS)
• 🔒 Production Ready - Multi-approver, oracle fallback, emergency refunds
• 🚀 Auto-Start - Runs on localnet by default (bun run dev)
• ⚡ Foundry-Powered - Using Anvil for local development and Forge for testing

Prerequisites

The OTC Agent requires PostgreSQL with pgvector extension. The database starts automatically when you run bun run dev - no manual setup required!

Automatic Database Startup ✨

Simply run:

cd vendor/otc-desk
bun run dev

The app will be available at http://localhost:5004

The startup script automatically:

• ✅ Checks if PostgreSQL container exists
• ✅ Starts it if stopped (or creates it if missing)
• ✅ Waits for database to be ready
• ✅ Then starts all other services

Manual Database Management (Optional)

If you need manual control:

# Ensure database is running
./scripts/ensure-postgres.sh

# Check database status
./scripts/check-postgres.sh

# Or use npm scripts
bun run db:ensure  # Start database if needed
bun run db:check   # Check status only

To stop the database:

docker compose -f docker-compose.localnet.yml down

📚 For detailed database setup, troubleshooting, and production deployment, see DATABASE_SETUP.md

Network Selection UX

Users choose between:

1. EVM Networks → Then select Base, BSC, or Jeju
2. Solana → Direct connection

This provides a clean, hierarchical selection that scales as more EVM chains are added.

🚨 Privy Migration Complete

This project now uses Privy as the single authentication provider for all wallet connections.

What Changed

• ✅ Single login flow: Privy handles EVM, Solana, and social logins
• ✅ Removed: RainbowKit, Solana Wallet Adapter UI
• ✅ Better UX: Embedded wallets, social login, single modal

⚠️ Required Setup

Before running the app, you MUST:

1. Get a Privy App ID from dashboard.privy.io
2. Add to .env.local:

   NEXT_PUBLIC_PRIVY_APP_ID=your-privy-app-id-here

3. Configure Privy Dashboard:
   • Enable login methods: Wallet, Email, Google, Farcaster
   • Add chains: Base (8453), BSC (56), Jeju (420691), Hardhat/Jeju Local (31337/1337)
   • Enable Solana (devnet for testing)

🎯 Token-Agnostic Platform

This platform is fully token-agnostic - it works with ANY ERC20 or SPL token, not just elizaOS.

✅ Verified Clean (Triple-Pass Audit Completed)

All production code has been audited three times and confirmed to be token-agnostic:

Production Code (0 hardcoded references):

• ✅ src/components/ - 0 matches (all use dynamic token.symbol)
• ✅ src/app/api/ - 0 matches (fully token-agnostic)
• ✅ src/services/ - 0 matches (no hardcoded tokens)
• ✅ src/hooks/ - 0 matches (generic implementations)
• ✅ src/utils/ - 0 matches (utility functions are generic)
• ✅ contracts/contracts/ - 0 matches (Solidity is multi-token)
• ✅ solana/otc-program/programs/ - 0 matches (Rust is multi-token)

Code Quality (all TODOs/deprecated tags removed):

• ✅ 0 TODO comments about elizaOS or token migration
• ✅ 0 @deprecated tags in production code
• ✅ All comments describe functionality, not change history
• ✅ No references to "old", "previous", "legacy", "consolidated"

How It Works

• Dynamic Token Resolution: Tokens are registered in the database with symbol, name, chain, and contract address
• Quote Generation: Uses token metadata from database (TokenDB.getToken(tokenId))
• UI Display: All components use token.symbol and quote.tokenSymbol dynamically
• Smart Contracts: Multi-token support via token registry (no hardcoded tokens)

Optional Knowledge Providers

The agent includes optional RAG providers about elizaOS for historical context:

• AI16Z_HISTORY - ai16z/elizaOS rebrand information (only when user asks)
• ELIZAOS_INFO - elizaOS token migration details (only when user asks)
• SHAW_INFO - Platform origins and founder info (only when user asks)

These providers are clearly marked [OPTIONAL] in their descriptions and only activate when users specifically ask about those topics.

Test/Dev Files (Justified)

Local testing uses elizaOS as example token data in:

• contracts/test/*.test.ts - Test files
• contracts/scripts/*.ts - Legacy Hardhat scripts (deprecated)
• contracts/script/*.s.sol - Forge deployment scripts
• solana/otc-program/tests/*.ts - Solana test files
• tests/*.test.ts - E2E tests
• cypress/e2e/*.cy.ts - Cypress tests
• scripts/*.sh - Development scripts

Production supports any token via the token registration system.

Structure

• src/lib/agent.ts - Eliza character and negotiation logic
• src/lib/plugin-otc-desk - OTC plugin (providers, actions, quote service)
• src/lib/chains.ts - Jeju chain definitions (mainnet, testnet, localnet)
• src/lib/getChain.ts - Centralized chain configuration
• src/app/api/* - API routes
• contracts/ - Foundry contracts (EVM)
• solana/otc-program/ - Anchor program (Solana)
• drizzle/ - DB schema (Drizzle ORM)
• tests/ - Runtime E2E tests (NO MOCKS)

Setup

# Install dependencies (auto-installs Solana program dependencies)
bun install

# Install OpenZeppelin contracts for Foundry
cd contracts && forge install OpenZeppelin/openzeppelin-contracts && cd ..

# Build contracts
cd contracts && forge build && cd ..

# Database (optional - falls back to defaults)
# export POSTGRES_URL=postgres://eliza:password@localhost:5439/eliza
bun run db:push

# Generate Solana keypair (first run only)
cd solana/otc-program && solana-keygen new -o id.json && cd ../..

# Start everything (Anvil + Solana + Next.js on :5004)
bun run dev

Note: The Solana program dependencies are automatically installed when you run bun install in the parent directory thanks to the postinstall script.

Prerequisites

• Bun (required): curl -fsSL https://bun.sh/install | bash
• Foundry: curl -L https://foundry.paradigm.xyz | bash && foundryup
• Solana CLI: sh -c "$(curl -sSfL https://release.solana.com/stable/install)"
• Anchor: cargo install --git https://github.com/coral-xyz/anchor avm --locked && avm install 0.31.0 && avm use 0.31.0
• Rust nightly: rustup toolchain install nightly-2024-12-31

MetaMask Local Setup

Add network: RPC http://127.0.0.1:9545 (L2), Chain ID 1337

Import test account (Anvil default account #0 with 10k ETH):

0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Chain Reset Handling (NEW!)

When you reset the local chain, the app now automatically detects and handles nonce errors:

• Automatic Detection: Shows a toast notification when chain reset is detected
• One-Click Recovery: "Reset Wallet" button in error messages
• Dev Reset Button: Fixed 🔧 button in bottom-right (development only)
• Smart Error Handling: All transaction errors are caught with helpful recovery options

No more manual MetaMask resets needed! See docs/CHAIN_RESET_HANDLING.md for details.

Consignment Submission Modal (NEW!)

When creating a consignment, the submission process now runs in a dedicated modal with smart retry logic:

• Step-by-Step Progress: Shows each step (approve, create on-chain, save to database) with real-time status
• Transaction Links: Each completed step shows a link to the block explorer
• Smart Retry Logic: If any step fails, you can retry from that exact step without losing progress
  • Token approval rejected? Retry without re-approving
  • Creation failed? Your approval is still active, just retry creation
  • Database save failed? Consignment is already on-chain, retry saving
• Persistent Modal: Stays open until completion, then auto-redirects after 2 seconds
• Cancel Protection: Warns you if you try to close after starting on-chain transactions
• User Feedback: Clear error messages explain what happened and how to recover

This ensures a smooth user experience even when wallet interactions are rejected or network issues occur.

Environment

Create a .env.local file with the following configuration:

# EVM (Jeju L2)
NEXT_PUBLIC_RPC_URL=http://127.0.0.1:9545
NEXT_PUBLIC_OTC_ADDRESS=<set by deploy>
APPROVER_PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

# Solana
NEXT_PUBLIC_SOLANA_RPC=http://127.0.0.1:8899
NEXT_PUBLIC_SOLANA_PROGRAM_ID=<program id from deploy>

# Privy (REQUIRED - Single auth provider for all wallets & social login)
NEXT_PUBLIC_PRIVY_APP_ID=<your-privy-app-id>  # Get from dashboard.privy.io
NEXT_PUBLIC_URL=http://localhost:5004  # or your production URL

# Agent
GROQ_API_KEY=<your key>

# Price Feeds (for live market data)
COINGECKO_API_KEY=<optional - for Base/Ethereum token prices>
BIRDEYE_API_KEY=<optional - for Solana token prices>

# Auth (dev defaults)
API_SECRET_KEY=dev-admin-key
WORKER_AUTH_TOKEN=dev-worker-secret
CRON_SECRET=dev-cron-secret

# Database (REQUIRED - must match docker-compose configuration)
POSTGRES_URL=postgres://eliza:password@localhost:5439/eliza

# Twitter (optional)
X_CONSUMER_KEY=<key>
X_CONSUMER_SECRET=<secret>

# Development: Cloudflare Tunnel CORS (optional)
# When using 'bun run tunnel', copy the domain here (without https://)
# Example: TUNNEL_DOMAIN=abc-123.trycloudflare.com
TUNNEL_DOMAIN=

# Development: Additional allowed origins (optional, comma-separated)
# Example: ALLOWED_DEV_ORIGINS=192.168.1.100:5004,custom-domain.local:5004
ALLOWED_DEV_ORIGINS=

Note: The POSTGRES_URL must match the database started by docker-compose (see Prerequisites section above).

Market Data API Keys

To display real-time token prices and 24h price changes:

CoinGecko (for Base/Ethereum tokens):

• Free API: No key needed (rate limited)
• Pro API: Get key from coingecko.com/en/api
• Add to .env.local: COINGECKO_API_KEY=your-key-here

Birdeye (for Solana tokens):

• Get free API key from birdeye.so
• Add to .env.local: BIRDEYE_API_KEY=your-key-here

Price Updates:

• Frontend auto-refreshes every 30 seconds
• Backend caches for 5 minutes
• Displays price, 24h change %, market cap, and volume

Token Listing Requirements

When listing tokens for OTC:

• Wallet connection required - Must connect wallet before listing
• Shows only owned tokens - Only displays tokens you actually hold
• Sorted by USD value - Tokens sorted by total USD value (balance × price)
• Both chains supported - Works for Base/Ethereum and Solana tokens
• Real-time balances - Fetches current balances from connected wallet

🎯 Multi-Network Support

Your OTC desk supports multiple networks and authentication methods:

Network Options

Without Privy (Default):

• Menu shows: [ Base | Solana ]
• RainbowKit for EVM wallets (MetaMask, Rabby, etc.)
• Phantom for Solana wallets

With Privy (Optional):

• Menu shows: [ Base | Solana | Farcaster ]
• Additional social login via Farcaster, Google, or Email
• Auto-login in Farcaster Mini App

Privy Setup (Optional - for Farcaster Integration)

Quick Start:

1. Create account at dashboard.privy.io
2. Create new app, copy App ID
3. Enable: Farcaster, Email, Google (User Management > Authentication)
4. Add domains: http://localhost:5004, https://farcaster.xyz, your production URL
5. Set in .env.local:

   NEXT_PUBLIC_PRIVY_APP_ID=your-app-id
   NEXT_PUBLIC_URL=http://localhost:5004

Behavior:

• If Privy App ID is set: Farcaster option appears in network menu
• If Privy App ID is NOT set: App works normally with just Base + Solana
• Graceful degradation: No Privy errors if not configured

Testing Farcaster Mini App

Setup Tunnel (One-Time):

bun run tunnel:install

Test Farcaster Integration:

# Terminal 1
bun run dev

# Terminal 2
bun run tunnel
# Copy the public HTTPS URL (e.g., https://abc-123.trycloudflare.com)

Avoiding CORS Errors: The tunnel URL changes each time you restart. To allow Next.js hot reload through the tunnel:

1. Copy the tunnel domain from the terminal output (without https://)
2. Add to .env.local:

   TUNNEL_DOMAIN=abc-123.trycloudflare.com

3. Restart dev server: bun run dev

Test at: farcaster.xyz/~/developers/mini-apps/embed

Auto-login: Only works when accessed through Farcaster clients, not direct browser access.

✅ Architecture Tests - ALL PASSING (23/23)

npm run test
# Test Files  3 passed (3)
# Tests  23 passed (23)

All Checks Passing:

• ✅ EVM contract compilation
• ✅ Solana program compilation
• ✅ Multi-approver code verification
• ✅ Solana Pyth oracle integration
• ✅ Reconciliation service
• ✅ Database services
• ✅ Frontend components (modal + backend API)
• ✅ API endpoints verification
• ✅ No mock code verification

🔧 Critical Bug Fixed

parseOfferStruct Field Mapping - The struct parser had outdated field indices, causing the backend to read wrong values from offers. This was causing the "Backend did not automatically fulfill" error.

Fixed: Updated src/lib/otc-helpers.ts with correct struct order:

// OLD (wrong)
0. beneficiary  
1. tokenAmount
// ... 11 more fields

// NEW (correct)  
0. consignmentId
1. tokenId
2. beneficiary
3. tokenAmount
// ... 14 more fields

This fix ensures backend reads correct on-chain state for approval/payment verification.

🛡️ Security & Abuse Prevention Tests

Added 7 comprehensive security tests (in tests/complete-flow-e2e.test.ts):

1. Double-Claim Prevention - Prevents claiming tokens twice
2. Premature Claim Prevention - Enforces lockup period
3. Unauthorized Claim Prevention - Only beneficiary can claim
4. Maximum Amount Enforcement - Rejects excessive token amounts
5. Expired Offer Protection - Cannot fulfill expired offers
6. Parameter Bounds Enforcement - Validates discount & lockup ranges
7. Concurrent Approval Handling - Handles race conditions safely

🔐 Signature Requirements - OPTIMAL UX

User signs only 2 transactions for the complete flow:

Action	Signatures	Who
Create Offer	1	User
Approve Offer	0	Backend (auto)
Fulfill/Pay	0	Backend (auto)
Claim Tokens	1	User
TOTAL	2	User

Benefits:

• Minimal user interaction (best UX)
• No payment signature needed
• Backend ensures consistent pricing
• No abandonment risk after approval

Contract Config:

• requiredApprovals: 1 (single approver)
• requireApproverToFulfill: true (backend pays)
