Chainlink CRE Connect
Chainlink CRE Connect (CREC) is the client-facing interface to the Chainlink Runtime Environment. It gives applications two capabilities:
- Inbound — subscribe to verifiable on-chain events signed end-to-end by a Chainlink Decentralized Oracle Network (DON), on every supported network.
- Outbound — submit gas-less, account-abstracted operations (atomic batches of EVM transactions) that the DON broadcasts on-chain through your Smart Account.
You sign with the keys you already have. CRE Connect handles event verification, gas, nonces, relayers, and the on-chain account.
What you can build
| Capability | What it gives you |
|---|---|
| Verifiable events | A stream of on-chain events signed by the DON using Off-Chain Reporting (OCR), which your application can poll, decode, and re-verify locally against the on-chain DON signer set. |
| Gas-less operations | A single signed payload becomes one or more EVM transactions executed atomically by your Smart Account — with no gas, nonce, or relayer management on your end. |
| Protocol extensions | Pre-packaged, protocol-aware modules layered on top of CRE Connect. The first available is DTA. |
Understand the model
Start with the Architecture overview, then read the concept pages for the resources that make up the product:
- Channels — the top-level scoping unit.
- Watchers — how on-chain contracts are observed.
- Verifiable Events and Event Verification — how OCR signatures travel with every event.
- Operations & Transactions and EIP-712 Signing — how gas-less writes are authorized.
- Smart Accounts and Account Abstraction & Gas Sponsorship — the on-chain execution model.
- Confidence Levels — finality and latency trade-offs.
- Extensions — protocol-specific modules.
