Aether is a production-ready SDK for building autonomous agent-to-agent systems on Solana. It integrates the x402 Payment Protocol to enable intelligent agent communication and micropayment settlement.
---
## 🌟 Vision
**Aether** enables autonomous AI agents to orchestrate complex workflows on Solana—negotiating contracts, processing micropayments, and making intelligent decisions—all without human intervention.
### Core Capabilities
- **x402 Protocol** - HTTP 402 payment standard for autonomous API payments
- **Solana Integration** - High-speed, low-cost blockchain infrastructure
- **A2A Protocol** - Standardized agent-to-agent communication
- **USDC Payments** - Stable, predictable pricing for agent services
---
## 🎯 Features
### Autonomous Workflows
- **Agent Negotiation**: Autonomous term negotiation between agents
- **Intelligent Verification**: LLM-powered decision making
- **Automated Settlement**: x402-based micropayments in milliseconds
- **Zero Human Intervention**: Fully autonomous agent transactions
### Solana Performance
- **400ms Finality**: Lightning-fast transaction confirmation
- **$0.00025 Transaction Costs**: Economical micropayments
- **Native USDC**: Stable pricing without volatility
- **SPL Token Support**: Extensible payment infrastructure
### Agent Framework
- **SettlementAgent**: Executes x402 payments and settlement on-chain
- **x402 Facilitator**: Payment verification and USDC transfers
- **Protocol Support**: A2A and AP2 protocol implementations
---
## 📦 Installation
```bash
npm install aether-agent-sdk
```
---
## 🚀 Quick Start
```typescript
import { SettlementAgent } from 'aether-agent-sdk'
const agent = new SettlementAgent()
await agent.init()
const txHash = await agent.executeSolanaTransfer(
'merchant_wallet_address',
1.0 // USDC amount
)
console.log(`Payment sent: ${txHash}`)
```
