Lina

This is still in beta

Multi-chain AI trading agent built on ElizaOS. Trade across EVM + Solana from a single chat interface.

What It Does

Spot Trading

• EVM swaps via Uniswap (Base, Ethereum, Polygon, Arbitrum, Optimism)
• Solana swaps via Jupiter aggregator
• Cross-chain bridging via Relay Protocol

Perpetuals

• Hyperliquid (EVM) - up to 25x leverage
• Drift Protocol (Solana) - up to 20x leverage
• Position management, P&L tracking, liquidation alerts

Analytics

• Token prices (CoinGecko)
• Protocol TVL (DeFiLlama)
• On-chain flows (Nansen MCP)
• Crypto news (CoinDesk)

Wallets

• CDP wallet for all EVM chains
• Agent-managed Solana wallet with encrypted seed storage
• Unified dashboard across chains

x402 Micropayments

Lina can pay for premium APIs automatically using the x402 protocol.

How it works:

1. You ask Lina to fetch from a paid API
2. If the API returns 402 Payment Required, Lina reads the price
3. Signs a USDC payment on Base from your CDP wallet
4. Retries the request with proof of payment
5. Returns the data + transaction hash

Example: fetch https://premium-api.com/data with payment

Limits: Default max 1 USDC per request. Configurable via maxPayment parameter.

Requires: CDP wallet with USDC balance on Base

Future: bl0ck Integration

Lina will integrate bl0ck's privacy features via WASM:

• Shadow Pass - Prove wallet wealth without revealing addresses. Users can verify tier status (Ghost/Leviathan/Apex) for gated features without doxxing holdings.
• Phantom Wrapper - Anonymous token wrapping. Wrap SOL/SPL into private commitments, unwrap to any address without linkability.
• Nullifier System - Anti-replay protection for trades using zero-knowledge proofs.

Privacy layer ships after bl0ck circuit (monerochan-rs zkVM) hits mainnet.
