Title: Getting Your First Mint Transaction by Token Address Using 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 look at how to get your first mint transaction by token address using the Helius API and extracting the dev address.

Getting Your First Mint Transaction:

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

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

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

Request Body:

The request body should contain a list of minting events in JSON format. Events include 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 request text:

[
{
"id": 1,
"address": "0xTokenAddress",
"type": "mint",
"data": {
"amount": 1000,
"currency": "ETH"
}
},
{
"id": 2,
"address": "0xOtherTokenAddress",
"type": "transfer",
"data": {
"from": "0xAnotherTokenAddress",
"to": "0xThirdTokenAddress",
"amount": 500
}
}
]

Extracting Dev Address:

To extract the Dev address from the token address, you can use the getasset endpoint to get the resource metadata for the token.

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

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

• address: token address

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

You can then extract the dev address from this response.

Extracting the Dev Address response:

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

The devAddress field is empty in the above example, but you may need to check the specific structure of the response.

Putting it all together:

To get the first mint transaction by token address and extract the dev address, follow these steps:

• Get the first mint event using the Helius API.

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

• Use the getasset endpoint to get the asset metadata for the token.

• Extract the devAddress field from the response.

Here is an example Python snippet:

“`python

import requests

def get_first_mint_transaction(token_address):

Get the first mint event using the Helius API

url = “

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

events = response.json()[‘events’]

Extract event-related data

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

Get asset metadata using the getasset endpoint

url = “

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

assets = response.
