Transaction Checker API
Simulate transaction and signature requests and analyze their outcomes before they occur.
Simulate and analyze transactions & signature requests across all major EVM compatible chains.
See all gains, losses, and approvals for any potential transaction or signature request.
Know if you are interacting with scam wallets, contracts, or websites.
How it works
The Transaction Checker API works by simulating the transaction or EIP-712 signature request in a sandboxed environment of the blockchain and analyzing these outcomes using machine learning and heuristic engines. By doing so, it can provide insight into the transaction or signature request including:
- Tokens/NFTs/ETH being sent or received
- Approval changes that grant/revoke permission to others to access the wallet's assets
- State changes to smart contracts
- If the transaction/signature request involves a scam contract or wallet
What we look for:
|Approval changes||Check if there are any permissions to access the wallet's assets being|
granted or revoked.
|Balance changes||Check for any NFTs/Tokens/ETH being sent or received.|
|Scammer counterparties||Check if any of the wallets or contracts involved in the transaction|
are known to be scammers.
|Security vulnerabilities||Check any contract involved in the transaction for security|
vulnerabilities in the source code that could lead to attacks that
might drain assets or otherwise allow unauthorized changes. See the
Smart Contract Weakness (SWC) Registry for some examples.
|Scam contract code||Check any contract involved in the transaction for code patterns or|
behaviors that are known to be used in scam contracts (i.e.
|Verified contract code||Check if any contract involved in the transaction has verified source|
|ERC compliance||Check if any contract involved in the transaction is compliant with|
any of the typical ERC standards for NFTs (ERC721, ERC1155) and
|Domain impersonation||Check if the website that triggered the transaction appears to be|
impersonating a legitimate site (i.e. NFT project sites, marketplaces).
|Unintentional burning||Check send tokens to their own contract in a way that would|
effectively burn them unintentionally.
Simulate and analyze transaction requests before presentng to the user in order to provide details on what will happen and protect them from potential scams.
