# WAIaaS — Wallet-as-a-Service for AI Agents

> Self-hosted local daemon that gives AI agents secure, policy-controlled access to crypto wallets.

## Overview

WAIaaS is an open-source Wallet-as-a-Service daemon designed for AI agents. It runs locally on the user's machine and provides REST API, MCP (Model Context Protocol), and TypeScript SDK interfaces for wallet operations.

## Key Facts

- **Type**: Self-hosted Node.js daemon (not a cloud service)
- **Install**: `npm install -g @waiaas/cli` or Docker (`waiaas/daemon`)
- **License**: Open source
- **Chains**: EVM (Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche, BNB Chain, HyperEVM) + Solana
- **Assets**: Native tokens, ERC-20, SPL tokens, NFTs (ERC-721, ERC-1155, Metaplex)

## Interfaces

- **REST API**: OpenAPI-documented HTTP endpoints on localhost (default port 3100)
- **MCP Server**: Built-in Model Context Protocol server for direct AI agent integration
- **TypeScript SDK**: `@waiaas/sdk` for programmatic access
- **Wallet SDK**: `@waiaas/wallet-sdk` for mobile/desktop wallet signing apps
- **CLI**: `waiaas` command-line interface for setup and management
- **Admin Web UI**: Browser-based dashboard at `/admin/`

## Security Model

Three-layer security:

1. **Session Authentication**: JWT-based session tokens with configurable TTL
2. **Time Delay + Owner Approval**: Configurable delay periods and human-in-the-loop approval via WalletConnect, Telegram Bot, or Wallet SDK
3. **Monitoring + Kill Switch**: Transaction monitoring, spending limits, audit logs, and emergency kill switch

Default-deny policy engine: tokens, contracts, and spenders must be explicitly whitelisted.

## DeFi Protocols (13+)

- **Swap**: Jupiter (Solana), 0x (EVM), D'CENT Swap Aggregator
- **Bridge**: LI.FI (cross-chain), Across Bridge
- **Staking**: Lido (ETH), Jito (SOL)
- **Lending**: Aave V3 (EVM), Kamino (Solana)
- **Yield**: Pendle (EVM)
- **Perpetuals**: Drift (Solana), Hyperliquid (HyperEVM)
- **Prediction**: Polymarket (Polygon)

## Smart Account

ERC-4337 Account Abstraction support with Lite/Full modes, gas sponsorship via paymasters, CREATE2 address prediction, and UserOp build/sign API. Supports Pimlico and Alchemy providers.
