Why Revoked Mint & Freeze Authorities Matter on Solana

Two settings on a Solana token account carry outsized power over every holder. Understanding them is one of the most practical due-diligence steps you can take before putting any amount into a project.

Nothing in this article is financial advice. Crypto assets, including TAIL, can lose all value. Always verify on-chain and do your own research before making any decision.

The basics

What are SPL token authorities?

On Solana, every token created through the SPL Token program can be assigned up to four special permissions, called authorities. Two of them are the ones you should always check.

Mint Authority

A mint authority is a keypair permitted to call the MintTo instruction on the token program — in plain terms, it can create new tokens at will and send them anywhere. If a project retains its mint authority, the total supply you see today is not final. More tokens can appear at any time, diluting every existing holder. This is the mechanism behind many rug-pull and "honeypot" attacks: the team mints millions of extra tokens and dumps them on the market.

Freeze Authority

A freeze authority can call the FreezeAccount instruction, which locks a specific token account so its owner can no longer transfer, burn, or move those tokens. The tokens stay visible in the wallet but become completely immovable. A malicious team with a freeze authority can effectively confiscate the liquidity value of your holding without ever taking direct ownership — you simply cannot exit.

The key concept

What does "revoked" actually mean?

On Solana, revoking an authority is a permanent, on-chain action. The current authority holder signs a transaction that sets the authority field to None in the mint account's data. Once broadcast and confirmed, no keypair in existence — not even the original team — can reinstate that authority without a hard fork of the entire Solana network. It is, in practical terms, irreversible.

Fixed supply, provably

With mint authority revoked, the token supply shown on-chain today is the supply that will exist forever. There is no admin key that can change it. This is a factual, verifiable property — not a promise from a whitepaper.

Your tokens stay yours

With freeze authority revoked, no address — including any team wallet or smart contract — can prevent you from moving your TAIL. Your wallet's private key is the only thing controlling your balance.

Anyone can verify it

These authority fields are stored in public, readable account data. No trust required. Any block explorer — including Solscan — will display them directly on the token's page. Verification takes under a minute.

Step-by-step

How to verify authority status on Solscan

You do not need to trust any project's claims. Here is exactly how to check any Solana token in under two minutes.

Step 1

Open Solscan and navigate to the token page

Go to solscan.io and paste the token's mint address into the search bar. For TrustTails, that address is 4NoNV3jSYLRbUtVWSTK5XdkpuvRzGpMCmfZSBKMuk6Rc. You can also use the direct link below.

Step 2

Look at the "Overview" panel

On the token's overview page, Solscan displays a summary card near the top. Look for two fields: Mint Authority and Freeze Authority. These fields will show either a wallet address (still active) or the word Disabled.

Step 3

Confirm both read "Disabled"

If either field shows a wallet address, that authority is still active. If both fields say Disabled, the authorities have been revoked and cannot be reinstated. For TrustTails (TAIL), both fields should read Disabled — verify this yourself rather than taking our word for it.

Step 4

Cross-check the supply figure

While you are there, confirm the total supply matches what the project claims. For TrustTails, the verified total supply is exactly 1,000,000,000 TAIL — no more, no less. A mismatch between a project's claimed supply and the on-chain figure is a serious warning sign. Learn more about full verification in our how to verify a Solana token guide.

Context

Necessary — but not sufficient

Revoked authorities are a meaningful baseline check. They are not a guarantee of a project's quality, longevity, or value. Here is how to think about them honestly.

What revoked authorities confirm

The team cannot mint additional tokens to inflate supply or dilute holders
No address can freeze your token account and prevent you from selling or moving your tokens
These properties are permanent and verifiable on-chain — you do not need to trust a claim in a whitepaper
Two common attack vectors used in low-quality token launches are structurally impossible with this token

What revoked authorities do not confirm

That the project will succeed, gain adoption, or retain any value over time
That the initial token distribution was fair — check wallet concentration separately
That smart contract logic (if any) is safe — a separate code audit addresses this
That the liquidity pool (when one exists) cannot be removed by pool owners — check LP lock status separately

Revoked authorities eliminate two specific risks. They sit alongside — not above — other checks such as wallet concentration, liquidity lock status, team transparency, and the project's stated purpose. Our security overview and Is it legit? pages cover the fuller picture of how to evaluate a token holistically.

Pre-launch notice: TrustTails is not yet trading. There is no Raydium pool or exchange listing at the time of writing. Be cautious of anyone claiming to sell TAIL tokens now, offering presales, or DMing you with early-access offers — these are scams. Follow only the official channels: X (@trusttailscoin) and Telegram announcements.

Stay safe

Authority checks in the context of scam awareness

Understanding authorities also helps you spot a specific class of scam that targets pre-launch communities.

Fake token clones

Bad actors sometimes deploy copycat tokens with the same name and logo as a legitimate project — but with active mint and freeze authorities. Always check the contract address before interacting with any token. The only real TAIL address is 4NoNV3jSYLRbUtVWSTK5XdkpuvRzGpMCmfZSBKMuk6Rc. If an authority field on any token page shows a wallet address instead of Disabled, treat that token as suspect regardless of what name it carries.

Unsolicited DMs and "presale" offers

No member of the TrustTails team will contact you privately to offer tokens, whitelist spots, or early-access deals. Anyone doing so is not affiliated with the project. TrustTails is pre-launch and has made no presale offers through any channel. All official announcements go through the verified Telegram announcements channel and X account only.

Quick answers

Common questions about SPL authorities

Can a revoked mint authority ever be restored?

No. On Solana, once an authority is set to None through the SPL Token program's SetAuthority instruction, that change is permanent. The on-chain account data no longer references any keypair as the authority, and there is no mechanism in the protocol to restore it without a network-level change affecting all Solana participants. This is one of the most robust guarantees available in the SPL ecosystem.

Does revoking authorities mean the token has been audited for security?

No. Revoking mint and freeze authorities is an action at the token-account level. It eliminates two specific risks (new supply creation and account freezing). It does not constitute a smart contract security audit, and it does not say anything about how initial tokens were distributed, whether liquidity is locked, or whether the project's goals are credible. Treat it as one important data point alongside the others described in our security page and Is it legit? overview.

What other authorities exist on SPL tokens and should I check them too?

The SPL Token program supports four authority types: Mint, Freeze, Account Owner (which controls a specific token account, not the mint itself), and Close Account. The mint-level authorities most relevant to holder safety are Mint Authority and Freeze Authority — the two covered on this page. Account Owner and Close Account authorities operate at the individual wallet account level and are standard features that every token holder controls for their own accounts, not something the token issuer holds.

If TrustTails is pre-launch, where can I learn more without relying on hype?

The best place to start is the whitepaper, which documents the project's thesis, token distribution, and the distinction between confirmed plans and long-term aspirations. The Is it legit? page walks through a systematic checklist a sceptical reader might apply. For community discussion, the Telegram community is the main channel. All official announcements are on the announcements channel.
