The Pearl Path Protocol (P3) is the core smart contract layer for Pearl Digital, derived from the MIT licensed Frictionless protocol.

It establishes a regulated, institutional-grade infrastructure for an Agent-Native Economy, specifically supporting public permissioned stablecoins and tokenized cash.

The Pearl Path Protocol delivers the on-chain Agentic Registry, the authoritative system of record that binds identities to wallets and enforces compliance pre-settlement.

The Agentic Registry and the Know Your Agent (KYA) Specification ensure Agents operate autonomously but never independently; they are always anchored to a verified Principal and act via a Proof of Agency (PoA): A cryptographic hash (Mandate Seal) defining the agent's scope, quantitative value limits, and validity period.

P3 Agentic Registry SDK is the off-chain companion to the Pearl Path Protocol (P3), the smart contract layer for the Pearl Digital Agentic Registry.

P3 is purpose-built for the machine economy: gasless x402 and HTTP-native settlement, autonomous agent micropayments, yield-bearing stablecoins, and a searchable registry of verified agents — all under pre-settlement compliance enforcement.

This SDK provides the tooling for AI agents and their Principals to interact with the Agentic Registry and execute within the protocol:

DelegationCredential Builder — DSL for Know Your Agent (KYA) credentials defining an agent's scope, value limits, and validity.

Mandate Seal Generation — Canonical serialization and Keccak256 hashing producing the Proof-of-Agency (PoA) hash stored on-chain by registerAgent(), byte-identical to the Solidity equivalent.

EIP-3009 Signing — transferWithAuthorization helpers for gasless, concurrent x402 micropayments in PRLUSD and FlashD, no native gas needed.

Batched Nanopayments — Pay many recipients in one atomic on-chain transaction, with pre-flight that strips reverting recipients (~77% lower per-payment gas at scale).

Treasury Yield — Swap and sweep stablecoins (PRLUSD ↔️ FlashD) and on-ramp external ERC-20s into yield-bearing positions.

Agent Discovery — Search the registry for verified, compliant agents by capability, risk class, principal, and reputation.

Boundary Policy Engine — Validates agent actions against their DelegationCredential limits before submission.

MCP Tooling — Model Context Protocol server exposing the registry so agents can query, build credentials, and pay within their delegated authority.

Integrations — Tether WDK, WalletConnect Pay (with P3 payer compliance), and x402 seller middleware.

Agents operate autonomously but never independently — always anchored to a verified Principal, always within the boundaries of their Proof of Agency.
