Supported networks and swaps
SandwichCheck performs read-only analysis against configured Ethereum RPC providers. Coverage is explicit so a result is not mistaken for a broader guarantee.
Available now
Ethereum Mainnet · chain ID 1
Analyzes mined transaction hashes through a configured Mainnet RPC endpoint.
Sepolia · chain ID 11155111
Provides the same receipt-based analysis for mined Sepolia transactions.
Uniswap v2 and v3 swaps are recognized from their standard pool event logs, without a hardcoded router or pool allowlist. The detector checks up to 12 transactions before and after the selected transaction.
Not yet supported
- Wallet-wide transaction history without an external indexer
- Protocols that do not emit supported Uniswap-style swap events
- Cross-block, cross-domain, or private-order-flow attribution
- Guaranteed attacker profit or victim-loss calculation
The service is read-only and never requests a signer or private key.
What expansion requires
Each additional network and protocol needs verified contract addresses, calldata decoders, pool discovery, trace support, token metadata, archive-quality RPC access, and protocol-specific tests.
