The ONCHAIN® Protocol Network (OPN)
OPN (pronounced “open”) is the deterministic execution layer beneath ONCHAIN® — fulfilling BuyIntents natively on each chain.
Core Components
1. BuyIntent
A canonical, tamper-proof representation of a user’s request:
Token
Chain
Amount
Wallet
Timestamp
2. IntentRegistry
An on-chain anchor guaranteeing:
Transparency
Non-repudiation
Replay protection
3. Deterministic Execution
OPN uses:
Prefunded USDC Solver Treasuries
Local DEX routing
Guaranteed settlement
Predictable execution behavior
4. Local, Native Settlement
Tokens settle on their home chain. No bridging. No wrapping. No synthetic IOUs.
5. Solver Treasuries
Execution liquidity:
Non-custodial
USDC-denominated
Fully withdrawable
Rebalanced automatically
Execution Flow
Gateway verifies payment
Gateway broadcasts BuyIntent
OPN swaps USDC → token
Token settles to the user wallet
Treasury rebalances as needed
OPN turns a link into confirmed ownership — deterministically and globally.
