Ethereum Rug Checker: Free Rug Check for ETH and Base Tokens
Paste a 0x contract address and DeFade rug checks it on Ethereum, Base or Robinhood Chain: contract permissions and taxes, who holds the liquidity and whether it is locked, what the deployer did with their previous tokens, who bought in the launch block, and whether the top holders are one wallet wearing twenty addresses. One rug risk score from 0 to 100, the evidence underneath, 3 free scans a day.
Rug check an Ethereum or Base token →Why Ethereum rugs look different from Solana rugs
On Solana the contract is a template and the rug is in the wallets. On Ethereum and Base the contract is still custom code, so the old rugs never went away: an owner who can mint, a sell tax that goes to 99% after launch, a blacklist, a proxy that can be upgraded into anything. An Ethereum rug checker has to read those permissions from the live contract state. DeFade does, and it treats "ownership renounced" as one input rather than a green light, because a contract can be primed before it is renounced.
Then the Solana-style rugs arrive on top. Cheap gas on Base makes wallet farms nearly free, so bundled launch blocks, sybil holder lists and deployers with dozens of dead tokens are now routine on EVM chains too. The Base rug-check guide walks through a real one.
What the Ethereum rug check inspects
| Check | What it reads on Ethereum and Base | Weight |
|---|---|---|
| Contract permissions | Owner functions still live, mintability, blacklist and trading toggles, buy and sell tax settings, whether the contract sits behind an upgradable proxy. | High |
| Deployer history | Every earlier token from the deployer wallet and how it ended. One in three Solana rugs came from serial deployers; EVM deployers are no different. | High |
| Launch bundles | Wallets that bought in the launch block or the blocks right after it, and whether they share a funder. | High |
| Insider clusters | Top holders traced through funding hops to a common origin, with exchange and router addresses excluded. | High |
| Liquidity | Pool depth on the main DEX, who holds the LP tokens, and lock or burn status. | Medium |
| Holder concentration | Top-10 and top-20 supply share with known custodial and contract wallets removed. | Medium |
| Snipers | Block-zero buyers and their link to the deployer. | Medium |
Every module that raises the score is listed with what it found. Read the finding, not the number.
How to rug check an Ethereum or Base token
- Copy the contract address from Etherscan, Basescan, DexScreener or the project page. Confirm it is the token contract, not the pair.
- Paste it into the DeFade scanner. If the same address exists on more than one chain, pick the chain.
- Read the permissions first. Live owner functions plus an unlocked pool is the fastest no.
- Open the deployer history. A wallet whose last five tokens are all dead is telling you what happens next.
- Check bundles and insider clusters together. On Base especially, a "community" that is one funder is common.
What this rug checker does not do
DeFade does not audit source code line by line and does not simulate a sell to prove a honeypot. It reads on-chain state and wallet behaviour. Use it alongside a contract scanner if you want both layers; the Ethereum rug pull guide explains which questions each kind of tool can answer.
This page is about EVM chains. Solana has its own rules and its own page: Solana rug checker. The rug pull checker page explains the four kinds of rug the score is built around.

Frequently asked questions
- Does the Ethereum rug checker cover Base?
- Yes. Base is an Ethereum L2 with the same contract model, so the same checks apply, and low gas makes it the busier chain for token spam and wallet farms. Robinhood Chain is covered too.
- What does "renounced ownership" actually protect against?
- Only the functions that ownership gates in that contract. A renounced contract with a hidden mint or a tax that was set to 90% before renouncing is still a rug. DeFade reads the live permissions and tax settings rather than the renounce flag alone.
- Can it detect honeypots?
- It reads the permissions that honeypots rely on: blacklists, sell taxes, trading toggles and upgradable proxies. It does not simulate a sell, so a contract that hides its trap behind logic the chain state does not expose can still pass. Treat a clean permission check as necessary, not sufficient.
- Is the Ethereum rug check free?
- Yes. 3 scans a day with no account or wallet, on Ethereum, Base, Robinhood Chain and Solana. Pro removes the cap and unlocks the deeper wallet modules.
