# 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.
