Here is an article on how to get the first mint transaction based on a token address using a query with the Helius API and extracting the developer address:
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 transaction by token address, you need to use the “GET /tokens/{tokenAddress}/minting” endpoint with the request body. Here is an example of how to do it:
”bash
curl -X GET \
\
-H “Authorization: Deliverer YOUR_API_KEY” \
-H “Content-Type: application/JSON”
Replace {tokenAddress} with the address of the token from which you want to receive minting transactions.
Requesting Entity:
The request body should contain a list of mining events in JSON format. The following information is included in events:
- "id": unique event identifier
address: token address
type': event type (e.g. "mint", "transfer")
- "data": event-related data
Here is an example of the query content:
json
[
{
"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 the creator address:
If To extract the developer address from the token address, you can use the getasset endpoint to get the token asset metadata.
''bash
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 access key address
- devAddress: the developer address (or 0xDevAddress if not found)
You can then get the developer address from this response.
Extracting developer response to address:
{
"asset": {
"address": "0xTokenAddress",
"devAddress": ""
}
}
In the above example, the "devAddress" field is empty, but you may need to check the specific structure of the response.
All things considered:
To get the first transaction of the platter by token address and extract the creator address, follow these steps:
- Get the first coin event using the Helius API.
- Expand the data associated with the event (including the "data" field).
- Use the getasset endpoint to get the token asset metadata.
- Extract the "devAddress" field 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 data related to 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'})
property = response.
