READ-ONLY BOUNDARY · Koschei never requests a recovery phrase, private key, custody or blind signature. Transaction simulation never signs or broadcasts.
Investigate an address.
Choose a network, collect the evidence, and inspect what controls the asset.
Ready. Select the network where you want to inspect this address.
Token investigation & transaction preflight
Collect the complete token evidence file: authority state, owner-resolved distribution, launch context, graph relations, liquidity, and explicit evidence limits.
EVM AUTHORITY INTELLIGENCE
Read the authority surface behind an address.
Ethereum, Base, Arbitrum and Optimism use the same evidence contract while chain identity remains explicit. Code, EIP-7702 delegation and ERC-1967 authority are observations — not automatic safety verdicts.
Read-only RPC evidence. No signing, custody or transaction broadcast.
Evidence standard
A premium interface should make the proof easier to inspect, not easier to hide.
Presentation never outranks evidence maturity.
Source-aware
Reports preserve where evidence came from and distinguish source failure from a clean finding.
Unknown stays unknown
Unavailable or incomplete evidence cannot silently improve a risk outcome.
Read-only boundary
Investigation does not require private keys, custody or transaction broadcast authority.
