Chainlink Automation Release Notes

Chainlink Automation is live on Base mainnet.

Payment in native gas tokens and approved non-LINK tokens is now available for upkeeps on Automation v2.3 or later. Currently this capability is available on the Base Sepolia testnet.

When you register a new upkeep, you can select whether you want to pay in LINK, the native gas token, or an approved non-LINK token for the chain that you are using. After you register the upkeep, the payment setting cannot be updated.

See the Supported Networks page to find the contract and config information for Automation on Base Sepolia testnet.

Log trigger upkeeps are now generally available. Learn more about how Chainlink Automation processes logs for log trigger upkeeps.

If you have any upkeeps that are not yet migrated to v2.1, using older registries that are paused, the only action you can take is either to migrate these upkeeps or to cancel them. Affected upkeeps will show a Deprecated label in the Chainlink Automation App. When you hover over the label, it displays a link you can click to begin the migration process.

Chainlink Automation is live on Base Sepolia.

Existing upkeeps on versions earlier than v2.1 will stop being performed on August 29, 2024. Migrate your older upkeeps to the latest version of Automation.

Older Automation registrars through v2.0 have already been deprecated, so you can't register new upkeeps on versions earlier than v2.1.

Chainlink Automation is live on Gnosis.

Older Automation registrars for v1.0, v1.1, v1.2, v1.3, and v2.0 are deprecated on all supported networks (Ethereum, Avalanche, BSC, Polygon, Arbitrum and Optimism). You can no longer register new upkeeps using these older versions. Please migrate your older upkeeps to Automation 2.1 to ensure they remain operational as we start deprecating older versions.

Chainlink Automation is live on Polygon Amoy.

The Mumbai network has stopped producing blocks, so example code will not function on this network. Check again soon for updates about future testnet support on Polygon.

The Automation StreamsLookup error handler is available to help you handle potential errors with StreamsLookup upkeeps. When you add the new checkErrorHandler function, you can define custom logic to handle some errors offchain and handle other errors onchain in performUpkeep.

Chainlink Automation is live on Optimism Sepolia.

The Chainlink Automation debugging script is available to help you debug and diagnose possible issues with registered upkeeps in Automation 2.1 registries. The script can debug custom logic upkeeps, log trigger upkeeps, and upkeeps that use StreamsLookup.

Chainlink Automation is live on Base.

Automation 2.0 is now live on Ethereum, Binance Smart Chain, Polygon, Avalanche, Arbitrum, and Optimism. Automation 2.0 features include:

• Verifiable compute: The Automation DON now leverages a consensus mechanism, via Chainlink OCR3, to give you cryptographically verified compute. Save up to 90% of onchain gas costs by off-loading compute intensive tasks to the Automation DON.
• Log triggers: Natively use log data in your smart contracts with log triggers. Unlock new connection possibilities.
• StreamsLookup: Seamlessly access and use Chainlink's Low Latency Data in upkeeps via StreamsLookup. Build like the best Derivative protocols.
• Forwarder: A unique msg.Sender for your performUpkeep function so you can lock down sensitive upkeeps. Read more about the forwarder.

Chainlink Automation is live on Optimism.
