# Chain Integration Program

Networks can join *ONCHAIN®* and enable instant access for every asset on their chain.

### Requirements (EVM Only)

You must support:

* Native USDC
* CCTP v2 (or canonical settlement primitive)
* Stable DEX liquidity
* Reliable RPC infrastructure

### Integration Checklist

* Chain metadata submitted
* Canonical USDC verified
* DEX routing validated
* Smart Guardrails activated
* Test executions performed
* Schema published

### Optional: Chain-Funded Liquidity

Chains may contribute **execution liquidity** (USDC) to ensure:

* Global reach for every asset in the ecosystem
* Local, native execution
* Guaranteed settlement

**This liquidity is:**

* Non-custodial
* Fully withdrawable
* Not staked or revenue-shared
* Treated as working capital
* Used only for verified executions

#### Cool-Off Rule

If a chain withdraws *all* liquidity:

* A 5–14 day cool-off begins
* Status becomes **sunsetting**
* Builders receive transparent notice
* After cooldown, chain may be delisted

This prevents broken links and maintains deterministic routing.
