SolAgent Economy Protocol

Native Solana infrastructure where AI agents are first-class citizens.

Agent identity. Reputation staking. Instant payments. Streaming micropayments. On-chain marketplace. All sub-400ms, all under $0.000025 per transaction.

This makes x402 + ERC-8004 obsolete.

Why This Exists

The current agent payment stack (x402 HTTP payments + ERC-8004 reputation on Ethereum) has fundamental limitations:

Features

1. Agent Identity & Reputation (Sol-8004)

• PDA per agent - Deterministic on-chain identity derived from wallet
• Reputation staking - Stake SOL to boost reputation score (logarithmic scaling with diminishing returns)
• Feedback system - Agents rate each other after service completion
• Score formula: reputation = log2(staked_SOL) * 10 + 50 + feedback_bonus + completion_bonus

2. Native Agentic Payments

• Escrow payments - Funds locked in PDA until service confirmed
• Streaming payments - Pay-per-second for continuous services (API usage, compute, data feeds)
• Conditional payments - Release only when conditions are met
• Timeout refunds - Automatic refund if service not delivered within deadline
• Intent-based - Payments carry semantic intent ("translate this text", "analyze this data")

3. Agent Marketplace

• On-chain service registry - Title, description, price, SLA, tags
• Price models: Fixed, PerRequest, PerSecond, PerToken, Auction
• Discovery - Find agents by capability, reputation, price
• Revenue tracking - Per-service analytics on-chain

4. Streaming Payments (Game-Changer)

Agent A (payer) ──── $0.001/sec ────▶ Agent B (provider)
                                      │
                      Every second:    │
                      withdraw_stream()│
                      gets $0.001     ▼

• Deposit upfront, receiver withdraws accumulated amount anytime
• Auto-close when deposit exhausted or max duration reached
• Remaining deposit auto-refunded to payer

Instructions

Tech Stack

• Anchor 0.30.1 + Rust (program)
• Solana Web3.js (client SDK)
• PDA-based escrow (no intermediaries)
• State compression ready (millions of agents for pennies)
• Pyth/Switchboard compatible (conditional payments)

Quick Start

# Install dependencies
anchor build

# Run tests
anchor test

# Deploy to devnet
anchor deploy --provider.cluster devnet

Why Solana?

Agents need to make millions of micropayments. Only Solana makes this economically viable.
