loop protocol v0.9·agent authorized infrastructure·solana mainnet + devnet

AI agents capture value.
Vaults compound it.
You own everything.

Loop Protocol is Agent Authorized Infrastructure for the agentic economy. Your agent (Claude, GPT, or custom) operates 24/7 with KYA authority — scoped session keys, on-chain policy enforcement, TEE attestation. Value flows through the Clearing House, settles into your self-custodial vault at 8-16% APY. No custody handoff. Instant revocation.

Agent Authorized Infrastructure

The AAI Stack

Three core primitives that enable autonomous agents to operate continuously while users retain full custody.

Know Your Agent

Scoped delegation without custody handoff

Users grant KYA permissions per-agent, per-layer. Agents operate with cryptographic session keys within policy limits. TEE attestation + MPC signatures. Instant revocation. You keep custody.

  • Session keys via Squads Protocol
  • 2-of-3 MPC threshold signatures
  • AWS Nitro TEE attestation
  • On-chain spending limits
Security Model
Clearing House

Trustless routing & verification for 23 economic layers

Every value capture event flows through routing decisions. 23 proof adapters (webhook, ZK, agent-submitted, on-chain). Durable handoff records with failure semantics. The protocol's nervous system.

  • Routing: routed / held / rejected / noop
  • 23 proof adapters per layer
  • Public audit trail (PII-redacted)
  • Portable across protocols
Live Activity
Vault + Cred

Self-custodial savings with 8-16% APY

Every capture deposits Cred into your vault PDA. Stack for yield (8% at 7 days, 16% at 2 years). Auto-restack. Social recovery. Automatic inheritance. Agent operates within limits, you retain ownership.

  • Cred: 1:1 USDC-backed stable token
  • Lock 7-730 days for tiered yield
  • PDA-bound, non-custodial
  • Inheritance + delegation built-in

Bring Your Own AI Agent

Loop is infrastructure.
Bring your intelligence.

Loop doesn't provide agents — it provides the economic layer. Claude, GPT, Grok, or your custom model can register via BYOAA, receive KYA grants from users, and operate within scoped session keys.

The Clearing House routes captures. The Vault settles value. Your agent provides the intelligence. That's the separation of concerns.

security model

Autonomous agents that cannot rug their users.

The security architecture achieves what seems impossible: agents operate 24/7 without user prompts, yet users retain full custody. No seed phrases. No custody handoff.

Passkeys

No seed phrases. Biometric auth via WebAuthn. Private keys never leave your device's Secure Element.

MPC + TEE

2-of-3 threshold signatures. Agent key share isolated in AWS Nitro Enclave with cryptographic attestation.

On-Chain Policy

Squads Protocol enforces spending limits, time locks, and operation thresholds. Revoke instantly.

capture primitives

23 economic layers.

Every type of economic activity Loop has scoped. Shopping is live. The rest are progressively hardening through real captures and protocol audits. This is proof of infrastructure generality — not just "shopping cashback."

the destination

Cred stacks. 8-16% APY.

Every capture deposits Cred into your vault PDA. Lock 7 days for 8%. Lock 2 years for 16%. Yield comes from real protocol fees — not inflation, not VCs. Self-custodial. Withdrawable. Inheritable.

  • self-custodial vault PDA-bound, your keys, withdrawable anytime (+ timelock for large amounts).
  • inheritance built in On-chain beneficiary designation. 90-day inactivity trigger. No probate.
  • auto-restack Mature stacks roll into the next tier automatically unless you withdraw.
