Displaying Events on the Solana Block Explorer

In this article, on the Solana Block Explay.

What is emit!?

On the Solana Blockchain, EMIT! 'Is a function used to send events to the network. Interact or the blockchain itself. In this case, we'll use it to display an event on the block explorer.

Defining the Event Structure

First, Let's Define The Event Structure:

Rest

#[Event]

PUB SPRUCT CLAIM EVENT {

Pub Engagement: U64,

}

`

This defines a simple Claimevent structure with a single fieldengagement

Using EMIT!

Now, let’s use EMIT! To send the Claimevent to the Block Explorer:

`Rest

EMIT! (Claim event {Engagement: 123});

`

However, as you mentioned earlier, this will only work if we define an event structure for it. Macro (available in Solana’s Peace Sdk) to define our custom event:

`Rest

use solana_sdk :: event :: {event, equal record};

#[Event]

PUB SPRUCT CLAIM EVENT {

Pub Engagement: U64,

}

Imp Event for Claim Event {

Fn signature (& self) -> & [u8] {

// Return the Event Signature (Not Shown in This Example)

Unimplemented! ()

}

}

`

In this updated code, we define and new claim event structure and implement theevent '. TheSignature () ‘Method is called to return

Displaying Events on Block Explorer

Module:

`Rest

use blockchain :: {block, event, blockid};

Fn Main () {

// Get the Current Block Id

Let Block_id = Block :: Blockid :: New ();

// Define An Event Record for Our Custom Event

Note_record = even record :: new ();

Event_record.set_field («Engagement», 123);

// Create a New Block Object

Let Block_Data = Block_Data! {

id: block_id.to_string () ,,

Events: some (vec! [Event_record.clone ()),

};

// Send the Block Data to the Blockchain

Let mut tx = block :: transaction :: new () set_data (block_data) .signer () build ();

Blockchain :: Send_transaction (& tx, «My-Transaction»);

}

`

In this examination, we use the blockchainSend_transaction ()` Function.

Example Use Cases

This example demonstrates how to display events on the solana block explorer. Such as:

• Displaying User Engagement Metrics

• Displaying Transaction History

• Logging API Calls

Like event on the solana blockchain.
