Function Discovery
Dispatcher-pattern analysis surfaces likely 4-byte selectors with opcode evidence. Curated signatures are matched only where high-confidence; everything else is honestly marked unknown.

What Opveil does
Evidence first, speculation never
Contract Intelligence
Real runtime bytecode from RPC, full disassembly with offsets, PUSH operands, jump markers, metadata-trailer handling, search, and export — pinned to block and code hash.
Risk Indicators
Deterministic checks for DELEGATECALL, upgrade authority, SELFDESTRUCT, external-call patterns, storage writes, and ownership surface — each with evidence, confidence, and limits. Never a safe/unsafe verdict.
Contract Comparison
Side-by-side bytecode hashes, normalized similarity, selector overlap, proxy structure, and findings — with exact vs heuristic matches clearly separated.
AI Explanations
A provider-agnostic LLM adapter explains evidence in plain language with finding references. Without a key, a deterministic summary is shown and AI-unavailable is labeled.
Proxy & upgrade tracing
EIP-1967 slots, beacon slots, and EIP-1167 minimal-proxy templates — with implementation code fetched and hashed separately.
How it works
Select network, paste address, inspect results
01
Select network
Choose Robinhood Chain or BNB Smart Chain. RPC endpoints are pinned per chain and overridable via environment.
02
Paste address
Checksummed EVM addresses are validated client- and server-side, then eth_getCode is read at a pinned block.
03
Inspect results
Overview, functions, bytecode, decompiled view, proxy, security, and AI explanation — all with provenance.
Uncover the code beneath.
Paste any deployed address on Robinhood Chain or BNB Smart Chain and get an evidence-backed dossier in seconds. Free, read-only, no wallet required.
