How BarryGuard Analyzes Ethereum and BSC Tokens
By BarryGuard Team · May 11, 2026 · 4 min read
EVM tokens — the kind that run on Ethereum, BNB Chain, and Base — work differently from Solana tokens. The checks BarryGuard runs on them are adapted to that world. Here is what we look at and what it means for you.
Owner rights
Every EVM token contract has an owner. That owner can have a lot of power — the ability to mint new tokens, pause trading, change fees, or blacklist wallets. BarryGuard checks what the owner can do, not just what they have done.
If the owner can mint unlimited tokens, that is a red flag. If they can pause all transfers whenever they want, that is another one. We tell you exactly which powers the owner holds so you can decide if you trust them.
Renounced ownership
When a token creator "renounces ownership," they give up their control over the contract permanently. No one can change the rules after that. It is like locking the door and throwing away the key.
BarryGuard checks whether ownership has been renounced. If it has, that is a good sign — the contract is locked in. If it has not, we tell you what the owner can still change.
Liquidity lock
Liquidity is the pool of tokens and funds that lets people buy and sell. If the creator can pull that liquidity out at any time, they can drain everyone's money — a classic rug pull.
BarryGuard checks whether the liquidity is locked (held in a contract that nobody can touch until a set date), burned (sent to an address that can never spend it), or unlocked (free for anyone to pull). Locked or burned is safe. Unlocked is a warning sign.
Tax functions
Some tokens charge a fee on every buy or sell — that is a "tax." A small tax that funds development or adds liquidity can be legitimate. But some tokens set hidden taxes that spike to 99% or 100% right before a rug, making it impossible for anyone to sell.
BarryGuard looks at the current buy and sell taxes, checks whether the owner can change them without warning, and flags contracts where the maximum possible tax is dangerously high.
Trading flags
Beyond taxes, a token contract can include other restrictions on trading. BarryGuard checks for:
- Blacklist / whitelist: Can the owner block specific wallets from trading?
- Max transaction amount: Is there a cap on how much you can buy or sell in one trade?
- Max wallet balance: Can the owner limit how many tokens a single wallet can hold?
- Cooldown period: Is there a forced delay between trades?
- Trading enable / disable: Can the owner turn trading on or off entirely?
Not all of these are bad — some are anti-bot protections. But when several of them appear together, especially with an active owner who can change them, the risk goes up fast.
What you get out of it
BarryGuard turns all of this into a single score from 0 to 100 with a plain-language risk level. You do not need to read a contract yourself or know what each function does. We do the reading and give you the answer.
Every check includes a one-line explanation so you can understandwhy the score is what it is. If a token scores Danger, you will see exactly which checks failed and what that means.
