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

1. Gateway verifies payment

2. Gateway broadcasts BuyIntent

3. OPN swaps USDC → token

4. Token settles to the user wallet

5. Treasury rebalances as needed

OPN turns a link into confirmed ownership — deterministically and globally.
