Description

The estimateFee function is an asynchronous function used to estimate the gas fee required for the mint operation of an ERC721 token on a specific blockchain and environment.

Parameters

Parameter	Data Type	Description
blockchain	string	The blockchain on which the ERC721 token exists.
contract	string	The contract type, in this case, 'erc721'.
functionType	string	The type of function for which to estimate the fee, in this case, 'mint'.
env	string	The environment or network of the blockchain.
amount (optional)	number	The amount of ERC20 tokens to be minted. (Only required for 'mint' functionType)

Response

Field	Data Type	Description
code	number	The response code indicating the success or failure of the operation.
result	number	The estimated fee for the contract deployment.
VLRYEstimate	number	The estimated fee in VLRY (virtual asset).
USDEstimate	number	The estimated fee in USD (United States Dollar).

Example Request and Response

Prerequisites

Before making requests with NO.AI SDK, you must have it installed.

You can install NO.AI SDK using either npm or yarn. Use the following commands to install NO.AI SDK:

npm install @nest25/evm-chains-lib
OR
yarn add @nest25/evm-chains-lib

Request

Here is an example of how to make a mint request using the NO.AI SDK:

const { Nft } = require('@nest25/evm-chains-lib');

const nft = new Nft('testnet');

async function main() {
    const result = await nft.estimateFee('eth', 'erc721', 'mint', 1);
    console.log("result", result);
}

main();

Response

  result {
        code: 1,
        result: 0.017027652251499114,
        VLRYEstimate: 214.49756246229526,
        USDEstimate: 32.17463436934429
      }

Use Cases

• Estimate ERC20 Mint Gas Fee: By invoking this function with the appropriate blockchain, contract, functionType ('mint'), and environment, you can estimate the gas fee required for the mint operation of an ERC721 token.

• Supporting Multiple Blockchains: The function allows estimating gas fees for ERC721 mint operations on different blockchains by specifying the blockchain parameter (e.g., 'Ethereum', 'Binance Smart Chain', etc.).

• Providing Results in Different Currencies: The function returns the estimated gas fee in the native currency of the specified blockchain, as well as its equivalent in VLRY and USD, providing flexibility for users who prefer different currencies.
