`estimateTokenCreationFee`

Estimates rent and fees for creating a new token using local heuristics only. No transactions are sent and the estimator does not call RPC fee endpoints.

Included costs: rent for the mint + metadata account(s), rent for a 165-byte ATA, and a local per-instruction fee model for a representative creation flow (create account, init metadata pointer, init mint, init metadata, create ATA, mintTo).

Usage

page.tsx


import { useConnection } from "@solana/wallet-adapter-react";
import { estimateTokenCreationFee, type TokenData } from "@okito/sdk";
 
const { connection } = useConnection();
 
const tokenData: TokenData = {
  name: "My Test Token",
  symbol: "TEST",
  imageUrl: "https://example.com/token-image.png",
  decimals: 9,
};
 
const feeInfo = await estimateTokenCreationFee(connection, tokenData);
