Start with a transaction.
Paste a hash to inspect its recorded execution.
Or enter an address to explore deployed bytecode.
FOLLOW THE EXECUTION
Every transaction has a story.
Reconstruct the calls. Follow the assets. Understand the outcome.

- One connected workspace
- Select an execution step to inspect addresses, calldata, gas and errors.
Internal calls require a supported trace. Receipt logs alone cannot reconstruct internal execution.
KNOW YOUR EVIDENCE
How Reversa reads execution.
Transaction replay
Reversa retrieves transaction, receipt and block data, then attempts debug_traceTransaction with callTracer. Playback navigates calls in depth-first order, up to 5,000 calls. It is not an opcode timeline. Events retain log indexes; they are not assigned to individual calls without evidence.
Token Flow
Shows Transfer logs with ERC-20 or ERC-721 shapes. Amounts remain raw units or token IDs. Emitting an event does not prove a contract implements the token standard correctly. Native ETH movements show transaction value and supported call-trace transfers, with reverted movements marked uncommitted. ERC-20 decimals and symbols are requested at the transaction block. Prices, net balances and ERC-1155 decoding are not implemented.
Contract Lab
Reads deployed bytecode and native balance at the latest block. PUSH4 constants are heuristic selector candidates, not a verified ABI. Sourcify supplies verified source and ABI when indexed. EIP-1967 implementation, admin and beacon slots and EIP-1167 patterns are inspected. Findings list observed permissions-related ABI names and proxy slots; they are not security verdicts. Approximate decompilation is not implemented.
Infrastructure
Public Robinhood RPC endpoints are the default. Server-side ROBINHOOD_MAINNET_RPC and ROBINHOOD_TESTNET_RPC environment variables support a dedicated provider. No wallet connection is needed. Recent analysis links carry the network and query; JSON export contains retrieved evidence.
