Read the contract before you sign.
Paste any token or contract address on Ethereum, BNB Chain, Arbitrum, Optimism, Polygon, Avalanche, Sonic, Linea, zkSync Era, Scroll, Fantom and Base. Dralvia buys a little and sells it back in a simulation that sends nothing, measures what selling really costs, reads what the owner can still do and who controls the owner, and looks for liquidity on 48 exchanges. Every finding comes with the evidence behind it.

What we read so you don't have to.
Each check reads the chain itself, in read-only calls that move no funds. Verified source comes from Etherscan, Blockscout, Sourcify or the network's own explorer. When something could not be checked, the result says so instead of guessing.
Buy-and-sell honeypot test
Dralvia buys a small amount and sells it back inside one simulated call, in the token's own pools. A sell that is refused, or returns nothing, is a honeypot, observed rather than inferred.
What selling really costs
The whole round trip: pool fees, any fee a Uniswap v4 hook keeps, and buy and sell taxes. A costly exit is checked against the token's other pools, and a pool that is simply too thin is told apart from a token that charges you.
Owner powers
Whether the owner can mint, pause, blacklist, change fees and taxes, or cap trades and wallets, and whether ownership was really renounced or the powers live on elsewhere.
Who controls the owner
The owner is followed to what controls it: a single wallet, a multisig and its threshold, or a timelock and its delay.
Proxy & upgradeability
EIP-1967, UUPS, transparent and beacon proxies: the implementation is read, and the upgrade authority named. A minimal-proxy clone is recognised as fixed, not upgradeable.
Liquidity, wherever it trades
Pools on 48 exchanges across 12 chains, from Uniswap v2 to v4 with hooks, Aerodrome, Velodrome and Liquidity Book. Whether the liquidity is locked or burned, and a pool that holds the token but trades nothing does not count.
Known-bad addresses
Addresses on the US sanctions list (OFAC SDN) are recognised whatever else the scan finds, and a request involving one is blocked.
Age, deployer and holders
How old the contract is, what its deployer did before, whether it still sits on a launchpad bonding curve, and how concentrated the top holders are.
Address in, verdict out.
Paste a contract address
Pick the chain. Dralvia reads the code, the verified source where it exists, and any proxy behind the address before analysis begins.
Simulate, then read
The buy-and-sell test runs in the token's own pools, owner powers and controllers are read from the chain, and the address is checked against known-bad lists.
Evidence you can act on
Safe, Caution or Avoid with the findings behind it, what could not be checked, and a one-click EvidencePack for the treasury or signing record.
Honest answers.
Ethereum, BNB Chain, Arbitrum, Optimism, Polygon, Avalanche, Sonic, Linea, zkSync Era, Scroll, Fantom and Base, all EVM chains. Non-EVM chains such as Solana and TRON are not supported yet; if you need one, tell us and we will shape the next chain by demand.
Scan a contract before funds move.
Paste an address, see whether it sells, what the owner can do, and export the evidence for your signing record.
Trust the whole picture, not one address.
Check a wallet or transaction
Approval exposure, drainer patterns, and counterparty risk before you confirm.
Inspect the link first
Most contract scams start with a lookalike site. Scan the URL before you connect a wallet.
