Cross-chain deployed Smart-contract to detect Honeypot and Slippage for DeFi tokens.
There is no magic only EVM(Ethereum Virtual Machine) features are involved. The contract simulate a buy/approve/sell execution in a single transaction and evaluate the results. Work with any UniSwap2 Router interface.

There is a TypeScript code snippet (example/index.ts)
const RunHoneyContract = async (
from: string, // Any existing address on the blockchain e.g. 0x573fbc5996bfb18b3f9b9f8e96b774905bcdc8b6 (find one from the Top Accounts https://cronoscan.com/accounts)
to: string, // The Honeypot checker contract Address e.g. 0xb5BAA7d906b985C1A1eF0e2dAd19825EbAb5E9fc
token: string, // the address of the token e.g. 0x062E66477Faf219F25D27dCED647BF57C3107d52 (wBTC)
router: string, // the DEX router address e.g. 0x145677fc4d9b8f19b5d56d1820c48e0443049a30 (MMfinance router on Cronos)
rcpAddress: string // Provide your EVM node e.g. https://evm-cronos.crypto.org
)
Result:
{
buyTax: 0,
sellTax: 0.3, // Passed 0.3% Tax detected
buyGasCost: 0,
sellGasCost: 0,
isHoneypot: 0
}
- Required to have a native currency trading pair available (wETH,wBNB,wCro...). Why? because it make no sense to support route like WrappedCoin -> USDT -> AnyToken.
- The available liquidity is lower than your simulation required
- The Contract is broken or not satisfy the Uniswap2 de facto requirement. (Whitelisting, Blacklisting, Trade Disable, MaxTx, Disallow Buy/Sell in same transaction, MaxWallet...)
- Slippage calculation already tested over 100.000 different Token pair.
- Honeypot checking could be bypassed it is still blockchain, but the aim here is to decrease risk.
