Orina Protocol is decentralized settlement infrastructure for bilateral commerce.
It enables two independent parties—or bounded software agents acting on their behalf—to agree on transaction terms, commit payment or assets, and reach one canonical onchain settlement outcome through a deterministic, time-bound state machine.
Orina covers the complete transaction lifecycle: order creation, seller confirmation, ERC-20 payment escrow, delivery confirmation, release, refund, cancellation, dispute resolution, timeout execution, fee routing, settlement receipts, and constrained machine-to-machine delegation.
Orina is not a marketplace, payment gateway, or custodial escrow provider. It is a composable protocol layer that marketplaces, wallets, OTC applications, service platforms, RWA systems, and AI-agent applications can integrate without rebuilding settlement logic independently.
The current ATP v3.5 contract stack is deployed on Optimism Sepolia. The deployment includes MarketplaceATP, PaymentGateway, DisputeManager, AutoTimeManager, FeeManager, RWAReceiptNFT, DelegationManager, AIWalletFactoryV2, and supporting registry and governance contracts.
The Optimism Sepolia deployment is public, write-enabled for testnet, bytecode spot-checked, and connected to the protocol’s bounded M2M delegation layer. Orina also has a public runtime application, technical documentation, Foundry testing, invariant campaigns, fuzzing, static analysis, formal verification artifacts, and an internal security review.
Orina remains testnet-operated. Independent security review, production governance, monitoring, and mainnet configuration are required before an OP Mainnet launch.
Orina’s mission is to establish deterministic bilateral settlement as reusable infrastructure on Optimism.
The proposed Optimism mission will convert the existing Optimism Sepolia implementation into an independently reviewable OP Mainnet deployment package and a public reference integration for commerce, RWA, service-payment, OTC, and autonomous-agent applications.
The mission will deliver:
Proposed six-month success metrics:
The expected ecosystem outcome is a reusable settlement layer that reduces duplicated infrastructure work for Optimism builders and enables applications to support complex two-party transactions without becoming custodial settlement authorities.
Onchain applications can transfer value efficiently, but a payment transaction alone does not resolve a bilateral commercial agreement.
Two parties still need a shared mechanism to define terms, hold funds, verify commitments, manage revised terms, enforce deadlines, handle disputes, and guarantee a final outcome without giving a centralized platform unilateral settlement authority.
Today, applications commonly implement these processes through custom escrow contracts, centralized support teams, offchain agreements, or fragmented workflows. This produces several recurring problems:
Simple payment and escrow contracts do not provide a complete bilateral settlement lifecycle. They usually handle custody and release, but not bounded delegation, revised terms, dispute finality, automatic timeout execution, receipt generation, and canonical state transitions.
The missing primitive is a reusable settlement protocol that preserves the identities of the parties, constrains delegated execution, and guarantees that every valid transaction path reaches a defined final state.
Orina solves this problem through the Atomic Transaction Protocol (ATP), a modular Solidity contract system for deterministic bilateral settlement.
MarketplaceATP acts as the canonical order-state coordinator. PaymentGateway handles ERC-20 escrow, seller payouts, buyer refunds, and protocol fee routing. DisputeManager provides multiple binding resolution paths, while AutoTimeManager allows permissionless execution of expired lifecycle windows.
Each transaction follows predefined state transitions and deadlines. Depending on the actions of the parties, the transaction resolves through release, refund, cancellation, dispute settlement, mutual agreement, or an automatic timeout outcome. No external application controls the canonical settlement state.
Orina’s DelegationManager adds bounded autonomous execution for AI and machine-to-machine applications. A delegation session can restrict:
The root buyer and seller identities remain unchanged. Delegates cannot redirect refunds, payouts, or settlement receipts and cannot perform sensitive user actions such as delivery confirmation or opening disputes.
For Optimism, Orina provides a reusable settlement primitive that applications can integrate instead of implementing separate escrow, dispute, timeout, and delegation systems.
The current Optimism Sepolia implementation demonstrates the full contract architecture. The next phase is to complete the Optimism-specific security, governance, runtime, documentation, and production-readiness work required for an OP Mainnet beta.
Orina uses a transaction-based protocol fee model. Settlements paid in supported stablecoins are charged up to 2%, while transactions using ORI are charged up to 1%. Fees are routed through the protocol’s PaymentGateway and FeeManager and may be allocated to platform operations, ecosystem participation, and approved referral components. The protocol is designed as infrastructure that marketplaces, wallets, OTC applications, RWA platforms, and AI-agent systems can integrate.
