Title: Getting the first mint transaction by token address using the Helius API

Introduction:

Helius is a popular decentralized finance (DeFi) platform that allows developers to create, manage, and trade tokens on the blockchain. In this article, we will explore how to get the first mint transaction by token address using the Helius API and extract the developer address.

Getting the first mint transaction:

To get the first mint transaction by token address, you need to use the GET /tokens/{tokenAddress}/minting endpoint with a requests request body. Here is an example of how to do it:

curl -X GET \
 \
-H 'Authorization: Deliverer YOUR_API_KEY' \
-H 'Content-Type: application/json'

Replace {tokenAddress} with the token address for which you want to get mint transactions.

Request Body:

The request body should contain a list of minting events in JSON format. Events contain the following information:

• id: Unique event identifier

• address: Token address

• type: Event type (e.g. mint, transfer)

• data: Data associated with the event

Here is an example of a request body:

[
{
"id": 1,
"address": "0xTokenAddress",
"type": "mint",
"data": {
"amount": 1,000,
"currency": "ETH"
}
},
{
"id": 2,
"address": "0xOtherTokenAddress",
"type": "transfer",
"data": {
"from": "0xAnotherTokenAddress",
"to": "0xThirdTokenAddress",
"amount": 500
}
}
]

Extracting developer address:

If you want To extract the developer address from the token address, you can use the “getasset” endpoint to get the asset metadata for the token.

curl -X GET \
 \
-H 'Authorization: Deliverer YOUR_API_KEY' \
-H 'Content-Type: application/json'

The response should contain an “asset” object with the following information:

• address: the token address

• devAddress: the Dev address (or “0xDevAddress” if not found)

You can then extract the developer address from this response.

Extracting the developer address response:

{
"asset": {
"address": "0xTokenAddress",
"devAddress": ""
}
}

The `devAddressfield is empty in the above example, but you may need to check the specific structure of your response.

To put it all together:

To get the first coin transaction by token address and extract the developer address, follow these steps:

• Get the first coin event using the Helius API.

• Extract the data associated with the event (including thedatafield).

• Use thegetassetendpoint to get the asset metadata for the token.

• Extract thedevAddressfield from the response.

Here is an example Python code snippet:

“python

import requests

def get_first_mint_transaction(token_address):

Get the first mint transaction using the Helius API

url = “

response = requests.get(url, headers={‘Authorization’: ‘Bearer YOUR_API_KEY’})

events = response.json()[‘events’]

Extract the data associated with the event

data = next(event[‘data’] for event in events)

Get asset metadata using the getasset endpoint

url = “

response = requests.get(url, headers={‘Authorization’: ‘Bearer YOUR_API_KEY’}) YOUR_API_KEY’})

assets = response.
