SAID Protocol

Solana Agent Identity — On-chain identity, staking, and trust infrastructure for AI agents.

Live: www.saidprotocol.com | Quick Start: npx said-sdk register

What is SAID?

SAID provides verifiable, on-chain identity for autonomous AI agents — with real economic security through staking and slashing.

Any agent can register for free. Verified agents stake SOL as collateral. Bad actors get slashed. Reputation is anchored on-chain with Merkle proofs.

The result: A trust layer that any agent platform, marketplace, or DAO can plug into.

Why It Matters

The agent economy has a trust problem. Anyone can spin up an AI agent, but there's no way to know:

• Who owns this agent? → SAID identity + wallet linkage
• Can I trust it? → Stake = skin in the game
• What has it done? → Receipt chain + Merkle-anchored history
• What happens if it scams? → Slashing burns the stake

Trust Tiers

Tier	Cost	Slashable?	Trust Score
Registered	Free	No	Base identity
Verified	0.01 SOL	No	+25 pts
Staked	0.1+ SOL	Yes	+25 pts
Reputed	Earned via activity	Yes	+50 pts

Trust Score (0-100) = Verification (25) + Stake (25) + Reputation (50)

Existing agents stay at their tier — staking is opt-in.

Core Features

Identity

• Free registration — On-chain identity at no cost
• Verification — 0.01 SOL one-time fee, Sybil-resistant
• AgentCard standard — JSON metadata for agent profiles
• Multi-wallet support — Link multiple wallets to one identity
• Authority transfer — Migrate agent ownership safely

Economic Security

• Staking — Agents stake SOL as collateral (0.1 SOL minimum)
• Slashing — Admin-gated, variable severity (25%, 50%, 100%)
• Slashable offenses: Wallet sale, rug pull, fraud, impersonation, malicious code, coordinated manipulation
• 100% burned — No profit motive for slashers, no securities concern

Unstaking

• 7-day cooldown — Request unstake, wait, then withdraw
• Emergency exit — Immediate unstake with 10% penalty burn
• Slash during cooldown — Bad actors can't escape by requesting unstake

Receipt Anchoring

• Merkle roots — Agents submit anchored receipt roots on-chain
• Sequential chaining — Continuity enforced, gaps rejected
• Verifiable proofs — Anyone can verify receipt inclusion against a root

Cross-Registry Compatibility

SAID is designed as a universal trust layer — any agent registry or platform can query SAID trust scores:

GET /api/trust/:agentOwner
→ { verification: 25, stake: 25, reputation: 50, total: 100 }

Other registries don't need to build their own staking/slashing — they use SAID.

Quick Start

# Install the CLI
npm install -g said-sdk

# Register your agent (free)
said register --keypair agent-wallet.json --name "MyAgent" --description "AI agent on Solana"

# Get verified (0.01 SOL)
said verify --keypair agent-wallet.json

# Stake SOL as collateral (min 0.1 SOL)
said stake --keypair agent-wallet.json --amount 0.1

# Add more stake anytime
said add-stake --keypair agent-wallet.json --amount 0.5

# Unstake: request → wait 7 days → withdraw
said request-unstake --keypair agent-wallet.json
said complete-unstake --keypair agent-wallet.json

# Emergency exit (immediate, 10% penalty)
said emergency-unstake --keypair agent-wallet.json
