Instant onchain executions with Block Triggers

Gelato's Functions are serverless, event-driven tools designed for automating blockchain transactions. They offer developers a powerful bridge between on-chain and off-chain activity, enabling execution of on-chain transactions based on arbitrary off-chain data and computation.

Introducing Block Triggers

Block triggers enable Gelato Functions to actively listen for new blocks and automatically execute smart contract functions as soon as a block is mined. This lets Functions synchronize with blocktime and carry out operations instantly.

Advantages for Developers

Block-triggered Web3 Functions bring several advantages:

• Lower Latency: Functions execute promptly with each new block, reducing wait times.

• Sync with Blockchain: By executing in tandem with new blocks, functions are always aligned with the latest state.

• Efficient Time Synchronization: Synchronization with block additions eliminates the risk of missed blocks and ensures timely execution.

Use Cases

Block triggers are beneficial in scenarios requiring immediate action in response to state changes:

• Limit Orders: Prevent delays in execution, safeguard against missed price targets or slippage, and avoid potential financial losses or missed opportunities.

• Perpetual Orders: Ensure immediate reactions, maintain the efficacy of perpetual strategies, and prevent suboptimal positions or uncontrolled risk.

How to Enable Block Trigger?

Implementing block-driven Web3 Functions is seamless. To create a new task with a block trigger:

1. Navigate to https://beta.app.gelato.cloud/.

2. Choose the "Every Block" option.

3. Under “What to trigger,” select “Typescript Function.”

4. Continue with the standard process.
