Freeze Authority and Update Authority Scams

Freeze Authority and Update Authority Scams: How Solana Memecoin Creators Trap Holders

• The Solana blockchain has established itself as the absolute epicenter of high-velocity token trading. Thanks to its low-latency execution, high throughput, and incredibly low transaction fees, the network attracts billions of dollars in daily trading volume. Millions of speculative assets, primarily memecoins, are launched, traded, and liquidated on Solana's decentralized exchanges every month.

However, the permissionless, cheap nature of Solana's ecosystem is a double-edged sword.

While it enables rapid, democratic financial experimentation, it also lowers the barriers for highly malicious actors.

• Unlike the Ethereum Virtual Machine (EVM), where scammers must deploy complex, custom-coded smart contracts containing hidden backdoors to execute a rug pull, Solana operates on a standardized, read-only library system.

This means that all tokens on Solana use the exact same foundational code.

• To trap buyers, ciber-criminals do not write custom malicious code; instead, they exploit native, built-in administrative privileges called authorities.

Among these administrative parameters, Freeze Authority and Update Authority are the two most frequently abused settings.

• By retaining these permissions, developers can turn a seemingly safe memecoin into an inescapable financial trap, locking wallets, manipulating descriptions, and siphoning away retail capital.

1. The Mechanics of Solana's SPL Token Architecture

• To understand how these authority-based scams operate, we must first look at the unique state-management architecture of the Solana Virtual Machine (SVM).

• In the EVM framework, every new token (such as an ERC-20 contract) is a unique, sovereign smart contract deployed to its own isolated address on the ledger.

• The developer has complete freedom to write arbitrary code within that contract, including custom balance-management functions, transfer restrictions, or hidden taxes.

Auditing an EVM token requires scanning the entire, compiled bytecode to ensure there are no malicious execution paths.

Solana handles tokens in a completely different manner:

• Standard Programs: All standard fungible tokens are managed by a single, read-only system contract called the SPL Token Program (or the more advanced Token-2022 Program).

• Mint Accounts: When a developer launches a new token, they do not write a new program. Instead, they initialize a standardized data account on the blockchain, known as a Mint Account. This account defines the core parameters of the token: total supply, decimal divisions, and designated administrative authorities.

• Associated Token Accounts: To hold a specific token, a user's wallet must initialize a secondary data account linked to that specific Mint, known as an Associated Token Account (ATA).

Because the execution logic resides in the immutable, secure SPL Token Program, Solana tokens are structurally identical.

Safety is not determined by custom contract code, but by who controls the configuration slots inside the Mint Account data state.

The primary authority configurations include:

• Mint Authority: The wallet allowed to print new token units into circulation.

• Freeze Authority: The wallet allowed to lock or unlock individual Associated Token Accounts.

• Update Authority: The wallet allowed to change the metadata (name, ticker, description, and logo) associated with the token.

If a developer retains control of these parameters, they retain absolute, central authority over how your wallet interacts with their token.

2. What is Freeze Authority? The Anatomy of a Solana Honeypot

• In the traditional corporate and regulatory landscape, Freeze Authority is an essential tool for maintaining compliance and managing security risks.

For example, when major stablecoin issuers like Circle (USDC) deploy their assets on Solana, they strictly maintain a Freeze Authority.

• This allows them to freeze the accounts of hackers, prevent the movement of stolen funds, or comply with international law-enforcement freeze directives.

• The developer of a compliance-focused token uses this function to freeze the account of an unauthorized holder, halting all outgoing transfers.

• However, in the highly speculative, anonymous world of Solana memecoins, Freeze Authority is used to construct the ultimate honeypot scam.

A honeypot is a token that users can easily buy but are structurally blocked from selling.

Here is how the honeypot scheme is executed step-by-step:

Step A: The Launch and Liquidity Injection

The scammer creates a fresh Mint Account, retaining the Freeze Authority and Mint Authority.

They deploy a liquidity pool on a decentralized exchange (such as Raydium or Orca), pairing their newly minted tokens with native SOL.

Step B: Marketing and Hype

The scammer deploys automated bot networks across social media platform X (formerly Twitter), Telegram, and Discord to hype the token.

• They manufacture artificial trading volume using wash-trading bots, causing the coin to climb the trending ranks of decentralized data dashboards.

Step C: The Trap is Sprung

• As retail traders and automated MEV bots buy into the rising token, their wallets automatically initialize Associated Token Accounts (ATAs) to hold the assets.

Once the liquidity pool is filled with native SOL from real buyers, the scammer executes a script.

This script calls the FreezeAccount instruction of the SPL Token Program, targeting every single retail ATA holding the token.

Step D: The Liquidation Drain

Because the retail users' accounts are now frozen, their tokens are permanently locked inside their wallets.

If they attempt to execute a swap on Jupiter or Raydium, the transaction fails with an error code.

With all external selling pressure completely frozen, the scammer uses their un-frozen developer wallets to sell their entire remaining allocation directly into the liquidity pool.

They siphon out all the SOL, leaving the frozen holders with completely worthless, unsellable tokens.

3. What is Update Authority? The Metadata Manipulation Scam

• Every professional token on Solana displays a visual identity: a custom name, a specific three-to-four-letter ticker symbol, a logo image, and a written description.

• Because Solana’s core Mint Account does not store this heavy visual data directly (to save expensive on-chain storage space), it uses the Metaplex Token Metadata Program or the new Metadata Extension in Token-2022.

The Mint Account points to a secondary metadata account containing a URI link.

The Update Authority is the specific administrative wallet that is permitted to edit this metadata.

Under normal project operations, keeping the metadata "mutable" is highly useful.

It allows the team to refresh their logo for holidays, update the website link in the description, or fix typos in the project's documentation.

However, in a memecoin scam, a mutable Update Authority is used to run a highly deceptive Bait and Switch or phishing scheme:

• The Safe Bait: The scammer launches a token under a generic, safe-looking identity (such as "Solana Community Coin" or "Glow Cat"). They pass all standard automated security audits because the token's distribution look clean, and they have revoked the Mint and Freeze authorities.

• The Metadata Switch: Once the token has attracted thousands of holders and significant trading volume, the developer executes a metadata update. They completely rewrite the name, symbol, and logo. For example, they might instantly change the token to mimic a highly anticipated, newly launched project or a trending, high-profile project.

• The Phishing Trap: Alternatively, the scammer will modify the token's description link. They insert an urgent message: "Claim your exclusive reward airdrop here!" pointing directly to a Drainer-as-a-Service (DaaS) website. Because the token already sits in thousands of user wallets, this instant, in-wallet advertisement reaches a highly targeted audience, tricking panicked holders into signing malicious authorization signatures.

4. Token Extensions (Token-2022) and Advanced Freeze Exploits

• As the Solana ecosystem evolved, developers designed the Token-2022 Program (also known as Token Extensions) to introduce advanced native capabilities, such as confidential transfers, transfer fees, and custom hooks.

• While these features represent a massive programmatic upgrade for corporate and institutional issuers, they have also provided malicious developers with highly sophisticated tools to automate their scams.

The most prominent extension abused by modern scammers is the Default Account State extension:

• The Legacy Constraint: Under the legacy SPL Token program, freezing a user's account required the creator to execute a manual, individual on-chain transaction targeting the user's specific Associated Token Account after it was initialized. If a user bought and sold very quickly, they could bypass the freeze script before it caught them.

• The Automated Trap: The Default Account State extension allows a token mint to predefine that all newly created token accounts are frozen by default. When a trader buys the token on a DEX, their wallet automatically initializes a new token account to receive the tokens. The instant the account is created, the extension automatically freezes it.

• The Gatekeeper Honeypot: To trade or sell the tokens, the user's account must be explicitly "approved" or thawed by the creator's freeze authority. The scammer can run a selective whitelist script: they thaw their own secondary wallets and those of their insider group, while leaving all real retail accounts locked in a frozen state.

Furthermore, scammers can abuse Transfer Fees.

By retaining the authority to adjust the token's transfer fee rate, a creator can set a dynamic tax.

They can launch the coin with a 0% tax to attract buyers, and once the pool is filled, adjust the transfer fee rate to 100%.

• This effectively functions as a structural freeze, as any attempt to transfer or sell the tokens results in 100% of the transaction value being diverted directly to the creator's fee collector address.

Solana Token Authority Status

To help keep your portfolio secure, understand how different authority configurations determine the safety of your funds:

5. Diagnostic Playbook: How to Audit Solana Authorities

• Because Solana’s contract logic is open and completely transparent on the public ledger, you can easily protect your capital by performing a quick administrative check before executing any trade.

A safe, decentralized memecoin should be completely ownerless.

This means that the creator must have permanently renounced their ability to manipulate the token's parameters.

When auditing a Solana token, verify these three critical conditions:

Mint Authority must be Set to Null

• If the Mint Authority is not revoked, the developer can mint an infinite number of new tokens out of thin air, completely inflating the supply and dumping them on holders.

Ensure the mint authority is set to null.

Freeze Authority must be Set to Null

If the Freeze Authority contains any active wallet address, do not buy the token.

The developer has the absolute power to freeze your wallet at any moment of their choosing, creating an instant honeypot.

Ensure the freeze authority is permanently revoked.

Metadata must be Marked as Immutable

Verify the status of the update authority.

• If the token metadata is set to mutable: true, the creator can change the token's logo, symbol, and description at any time, paving the way for a bait-and-switch phishing campaign.

The update authority should be permanently revoked, marking the metadata as immutable.

• Traders can utilize automated, real-time security tools like RugCheck or Solana block explorers such as Solscan and Orb to perform these audits instantly.

Entering the token's contract address into these scanners will highlight any unrevoked authorities as critical, high-risk red flags.

6. How Launchpads and DEXs Try to Standardize Safety

As authority abuse became the dominant source of fraud on Solana, decentralized launchpads stepped in to automate and enforce basic safety standards.

Platforms like Pump.fun and Moonshot have successfully captured a massive share of the Solana token launch market by hard-coding safety parameters directly into their initialization pipelines:

• Enforced Revocation: When a user launches a token through these platforms, the underlying smart contracts automatically configure the mint's settings. The Mint and Freeze authorities are permanently set to null on creation, and the metadata is locked as immutable.

• Liquidity Burning: Once a token reaches its target market capitalization, the platform automatically migrates the liquidity to Raydium and burns the liquidity provider (LP) tokens, preventing the creator from pulling the liquidity pool out of the AMM.

• While these automated launchpads have eliminated the "lazy" freeze and mint scams from their specific ecosystems, sophisticated scammers continue to bypass these barriers.

• They buy older, unrevoked tokens on the open market, construct custom Mint Accounts outside of standard launchpads, or use advanced Token-2022 programs to deploy transfer fee and default account state traps.

Because of this, manual auditing of any token before trading remains a mandatory survival skill on Solana.

Metadata Configuration Risk

7. The Defensive Framework for Solana Traders

Navigating the volatile Solana memecoin market safely requires a disciplined, proactive approach to security.

Relying on luck or assuming a token is safe because it is trending will eventually lead to a catastrophic loss of capital.

Implement these core rules to protect your Solana assets:

Check Before You Click

Never buy a token based strictly on a recommendation in a chat room or a trending post on social media.

Copy the token's Mint Address and run it through a verified Solana security scanner like RugCheck or Solscan.

Verify that the Mint and Freeze authorities are set to null, and check if the metadata is mutable.

Utilize Isolated Burner Wallets

Do not use your primary, long-term savings wallet to trade speculative memecoins.

Set up a separate, dedicated browser or mobile wallet containing only the small amount of SOL you are willing to risk on trades.

If you accidentally interact with a malicious token extension or sign a bad authorization, the potential damage remains strictly confined to your burner account, keeping your core wealth safe.

Understand the Unfreeze Limitation

• If you hold a token that has been frozen by a scammer, understand that neither your wallet provider (such as Phantom or Solflare) nor the Solana network validators can unfreeze your account.

• The only key that can unfreeze the Associated Token Account is the specific wallet designated as the Freeze Authority inside the token's Mint Account.

Since that key is held by the scammer, frozen assets are practically lost forever.

Prevention is your only true shield.
