DexTycoon Solana Token Filter Helpers

DexTycoon Solana Token Filter Helpers – A lightweight, efficient utility to check SPL Token 2022 extensions, mint authority, and freeze authority in Solana. Designed to protect users from scam and malicious tokens.

---

Why Use This Helper?

Solana is a fast-growing ecosystem with thousands of new tokens launching every day. Unfortunately, some tokens are malicious or scams that can:

• Have active mint authority allowing the creator to mint unlimited tokens.
• Have freeze authority that can lock users’ tokens unexpectedly.
• Use dangerous Token-2022 extensions (e.g., Transfer Hooks, Permanent Delegates, Pausable Config) to manipulate transfers or steal funds.
• Impose hidden transfer fees that can eat away your holdings.

This helper allows developers and traders to quickly and reliably validate tokens before interacting with them. By using this, you can:

• Avoid interacting with unsafe tokens.
• Automatically filter out scam or dangerous mints in bots or trading platforms.
• Ensure your Solana projects and liquidity pools only include safe, trustworthy tokens.
• Know explicitly if forbidden extensions are present or absent for each token.

Think of it as your first line of defense against malicious tokens on Solana.

Usage

Single Mint Check

import { PublicKey } from "@solana/web3.js";
import { connection } from "./utils/connection";
import { PoolFilterManager } from "./filters/pool-filter";
import { CHECK_FREEZE_AUTHORITY, CHECK_IF_MINT_IS_RENOUNCED, CHECK_MINT_FEE, ENABLE_FAST_MODE } from "./utils";
import { ExtensionType } from "@solana/spl-token";

// Array of mints to check
const mints = [
  new PublicKey("UXen71YJpLmm1qect5E8Bww3z2T798n1Wy4Ybs4PVFY"),
];

// Define filter options
const filterOptions = {
  checkFees: CHECK_MINT_FEE,
  checkMintRenounced: CHECK_IF_MINT_IS_RENOUNCED,
  checkFreezable: CHECK_FREEZE_AUTHORITY,
  forbidden: [
    ExtensionType.MintCloseAuthority,
    ExtensionType.PausableConfig,
    ExtensionType.ConfidentialTransferMint,
    ExtensionType.NonTransferable,
    ExtensionType.TransferHook,
    ExtensionType.PermanentDelegate,
  ],
};

(async () => {
  // Initialize the manager with options and concurrency
  const manager = new PoolFilterManager(connection, filterOptions, 20, ENABLE_FAST_MODE);

  // Execute batch check
  const summary = await manager.executeMany(mints);

  // summary.results will include messages indicating whether forbidden extensions are found or none are present
  console.log(summary);
})();

Batch Mint Check

import { PublicKey } from "@solana/web3.js";
import { connection } from "./utils/connection";
import { PoolFilterManager } from "./filters/pool-filter";
import { CHECK_FREEZE_AUTHORITY, CHECK_IF_MINT_IS_RENOUNCED, CHECK_MINT_FEE, ENABLE_FAST_MODE } from "./utils";
import { ExtensionType } from "@solana/spl-token";

// Array of mints to check
const mints = [
  new PublicKey("CVXB7XCjKyKCftyz6QqtUzzSJKPBF9ECoaEcaw5XLyyM"),
  new PublicKey("2X1N6hJSuHH9yJY7Hok5evMcsUaCXedE127k3jbMEzny"),
  new PublicKey("UXen71YJpLmm1qect5E8Bww3z2T798n1Wy4Ybs4PVFY"),
  new PublicKey("FdohLbj7wck1Qo3WwMNfMqjZWDTyzZYqYxL3NGTmaqGY"),
];

// Define filter options
const filterOptions = {
  checkFees: CHECK_MINT_FEE,
  checkMintRenounced: CHECK_IF_MINT_IS_RENOUNCED,
  checkFreezable: CHECK_FREEZE_AUTHORITY,
  forbidden: [
    ExtensionType.MintCloseAuthority,
    ExtensionType.PausableConfig,
    ExtensionType.ConfidentialTransferMint,
    ExtensionType.NonTransferable,
    ExtensionType.TransferHook,
    ExtensionType.PermanentDelegate,
  ],
};

(async () => {
  // Initialize the manager with options and concurrency
  const manager = new PoolFilterManager(connection, filterOptions, 20, ENABLE_FAST_MODE);

  // Execute batch check
  const summary = await manager.executeMany(mints);

  // summary.results will include messages indicating whether forbidden extensions are found or none are present
  console.log(summary);
})();
