Overview

What are blockchain events?​

Blockchain events, or on-chain events, are immutable records of actions occurring on the blockchain. These events ensure trust and transparency, vital for applications like financial transactions and voting systems. By using blockchain to record events, one guarantees the authenticity and integrity of data, safeguarding it from tampering or alterations.

These events can be categorized into:

  • Function Events: Triggered during the execution of a write smart contract function.
  • Log Events: Emitted in tandem with function events to record critical operational data.
  • Internal Transactions: Representing internal processes and exchanges within the blockchain.

On-chain events are pivotal in developing secure and reliable blockchain applications.

What is the Blocklens Trigger?​

The Blocklens Trigger is a dynamic tool that allows you to monitor real-time events on the blockchain. Whether tracking changes in your contract, overseeing wallet address activities such as transactions, burns, or mints of NFTs, or receiving notifications for every transaction, this tool keeps you updated instantly.

By subscribing to our plan, you gain access to exclusive webhook responses, tailor-made according to your trigger configurations, ensuring that you are notified of the events most pertinent to you.

Working With Webhooks​

Webhooks facilitate real-time information sharing between apps, enhancing immediacy and efficiency compared to traditional APIs. While traditional APIs necessitate frequent data polling to achieve real-time updates, webhooks automatically deliver data as events occur.

Here’s how it works: when a specified event takes place, a webhook sends an immediate notification through an HTTP POST to a designated URL, accompanied by a decoded data payload (based on the provided ABI). This setup ensures that you receive instant, pertinent data without the need for continuous manual checks.
