When you create a TRC20 token with Tron Token Generator, you can enable a range of powerful smart contract features that define how your token behaves. These features are baked into the contract at deployment and cannot be changed afterward — so choosing the right combination is one of the most important decisions you'll make.

This guide explains every available TRC20 feature in detail: what it does, how it works on-chain, which project types it suits best, and what to watch out for.

Important: All features are included in the flat 299 TRX deployment fee. Enabling more features does not increase the cost. However, once deployed, features cannot be added or removed. Plan carefully.

Mintable

What it does: Allows the contract owner (your wallet address) to create new tokens after the initial deployment, increasing the total supply at any time.

How it works: The contract includes a mint(address, amount) function callable only by the owner. New tokens are credited directly to any specified address.

Best for:

  • Staking rewards — mint tokens as yield for stakers
  • Play-to-earn games — mint tokens when players earn in-game
  • Subscription models — mint tokens as subscription is renewed

Watch out: Mintable tokens face trust concerns. If investors fear unlimited dilution, they may not hold. Always communicate your minting schedule and caps clearly. For community tokens and meme coins, it's usually better to avoid Mintable.

Burnable

What it does: Allows token holders (or only the owner, depending on configuration) to permanently destroy tokens by sending them to the zero address, reducing the total supply forever.

How it works: The contract includes a burn(amount) function. When called, tokens are deducted from the caller's balance and the total supply is permanently decreased. The event is recorded on-chain and irreversible.

Best for:

  • Deflationary tokenomics — scheduled burn events reduce supply over time, potentially increasing per-token value
  • Meme coins — burn milestones ("50% burned!") are a proven community engagement mechanic
  • Buyback-and-burn programs — repurchase tokens from the market and burn them
  • Fee burning — route a portion of protocol revenue to token burns

Pausable

What it does: Allows the contract owner to globally freeze all token transfers in an emergency, then unfreeze them when the situation is resolved.

How it works: The contract includes pause() and unpause() functions. When paused, all transfer() and transferFrom() calls revert — no tokens can move. The owner can unpause at any time.

Best for:

  • Security-sensitive projects — pause if a vulnerability is discovered while you patch it
  • Pre-launch phase — deploy the token, distribute it, then unpause when ready for trading
  • Regulatory compliance — projects in regulated spaces may need pause capability

Watch out: Pausable is a significant centralization risk. It means one wallet can freeze everyone's tokens. Disclose this clearly to your community.

Blacklist

What it does: Allows the contract owner to block specific wallet addresses from sending or receiving the token. Blacklisted wallets cannot transfer tokens in any direction.

How it works: The contract maintains a mapping of blacklisted addresses. Every transfer() call checks both sender and recipient against this list and reverts if either is flagged.

Best for:

  • Anti-bot protection at launch — blacklist known bot addresses immediately after deploying
  • Compliance requirements — KYC/AML-focused projects may need to block sanctioned addresses
  • Scam prevention — block known scammer or phishing wallets

Max TX (Maximum Transaction)

What it does: Sets a maximum number of tokens that can be moved in a single transaction. Any transfer exceeding this limit is rejected by the contract.

How it works: The contract checks amount <= maxTxAmount on every transfer. You set the max amount during deployment and can update it as the owner later.

Best for:

  • Anti-whale mechanisms — prevents large holders from dumping massive amounts at once
  • Fair launch protection — limits how much any single buyer can acquire in the initial period
  • Community tokens — keeps the token distribution more spread out and fair

Transfer Fee

What it does: Automatically deducts a percentage from every token transfer and sends it to a designated wallet (your marketing wallet, liquidity fund, or burn address).

How it works: On every transfer(amount), the contract calculates fee = amount * feePercent / 100, deducts it from the transferred amount, and routes it to the fee wallet. The recipient receives amount - fee.

Best for:

  • Auto-funded marketing wallets — every transaction contributes to your marketing budget
  • Auto-liquidity mechanisms — route fees back into the DEX liquidity pool
  • DeFi tax tokens — many DeFi protocols use fee-on-transfer mechanics
  • Meme coins — 1–5% buy/sell fees are standard in the meme coin space

Watch out: High fees (above 5%) significantly reduce trading appeal. Most DEX routers also require explicit fee-on-transfer handling, which can cause issues if not configured correctly.

Whitelist

What it does: Restricts token transfers to only approved (whitelisted) wallet addresses during a controlled phase. Non-whitelisted addresses cannot transfer the token until whitelisting is removed or expanded.

How it works: The contract maintains a whitelist mapping. Transfers are only permitted if both sender and recipient are on the whitelist (or if whitelist mode is disabled by the owner).

Best for:

  • Private sales and pre-sales — only pre-approved buyers can receive tokens initially
  • Vesting schedules — control who can move tokens during lock-up periods
  • KYC-restricted tokens — ensure only verified wallets can participate
  • DAO governance bootstrapping — controlled initial distribution

Reflection

What it does: Automatically distributes a percentage of every transaction to all existing token holders, proportional to their holdings. Holders earn more tokens passively just by holding.

How it works: On every transfer, a reflection percentage is taken from the transferred amount and redistributed across all holder balances in a single on-chain operation using a "rate" mechanism. As reflections accumulate, each wallet's balance grows without any manual claiming.

Best for:

  • Passive income tokens — reward long-term holders with automatic distributions
  • Holder reward programs — encourage holding over selling
  • Community tokens — create a "the more you hold, the more you earn" incentive

Watch out: Reflection increases gas costs for every transaction because all balances update. This is negligible on TRON (still fractions of a cent) but is a significant issue on Ethereum.

Which Features Should You Enable?

Here are our feature recommendations by project type:

Meme Coin

Enable: Burnable, Transfer Fee (1–3%), Max TX. Avoid: Mintable (trust risk), Pausable (community will worry)

See also: Meme coin guide
Utility Token

Enable: Mintable (for reward issuance), Burnable, Pausable (for security). Transfer Fee optional

Cost: All included in 299 TRX
Community / Rewards Token

Enable: Reflection (holders earn automatically), Burnable (deflationary), Max TX (anti-whale)

Pairs well with: Transfer Fee for auto-funding the reflection pool
Security / Compliance Token

Enable: Pausable, Blacklist, Whitelist. These give maximum owner control for regulated environments

Note: Disclose all admin controls clearly to your community

How to Enable Features

Frequently Asked Questions

No. Smart contract features are compiled into the bytecode at deployment time and permanently recorded on the blockchain. They cannot be added, removed, or modified after deployment. If you want different features, you would need to deploy a new contract with a new token address.

Transfer Fee routes a fixed percentage of every transaction to a specific wallet address (which you control). Reflection distributes the fee percentage automatically across all current token holders proportional to their balance — no specific wallet, just all holders collectively. You can enable both simultaneously.

The Transfer Fee feature itself is set at deployment. The specific fee percentage may be adjustable by the owner depending on the contract implementation — check the contract details when deploying. The Max TX limit is typically adjustable by the owner after deployment.

Not necessarily. Each feature adds complexity and has trust implications. Enable only what your project genuinely needs. For most simple community tokens, Burnable + Max TX is sufficient. For utility tokens, Mintable + Burnable + Pausable covers the main use cases. Enabling features you won't use can raise red flags for informed investors.

All Features, One Price: 299 TRX
