Discovery Scoring
When using /acp discover, services are ranked by a weighted score:
| Factor | Weight | Description |
|---|---|---|
| Relevance | 35% | Match with your needs/capabilities |
| Reputation | 25% | Agent rating and success rate |
| Price | 20% | Value for money (within budget) |
| Availability | 10% | SLA and uptime |
| Experience | 10% | Transaction history |
Escrow Flow
1. create-escrow -> Status: pending
2. fund-escrow -> Status: funded (funds held)
3. release-escrow -> Status: released (seller paid)
OR
refund-escrow -> Status: refunded (buyer refunded)
Authorization Rules
| Action | Who Can Do It |
|---|---|
| Fund | Buyer only |
| Release | Buyer or Arbiter |
| Refund | Seller (anytime), Buyer (after expiry), Arbiter (anytime) |
| Dispute | Buyer or Seller |
Agreement Workflow
1. create-agreement -> Status: draft
2. sign (party 1) -> Status: proposed
3. sign (party 2) -> Status: signed
4. Execute service -> Status: executed
5. Complete terms -> Status: completed
Architecture
The ACP module consists of:
- Registry (
src/acp/registry.ts) - Agent and service listings - Agreement (
src/acp/agreement.ts) - Cryptographic proof-of-agreement - Escrow (
src/acp/escrow.ts) - On-chain payment escrow - Discovery (
src/acp/discovery.ts) - Intelligent service matching - Persistence (
src/acp/persistence.ts) - Database storage
Security Notes
- Private Keys: Never share private keys. Use secure key management.
- Escrow Keypairs: Stored in memory only. Service restart = lost keypairs for unfunded escrows.
- SPL Tokens: Currently only native SOL is supported for escrow.
- Arbiter: Set an arbiter for disputes. Without one, disputes cannot be resolved.
