Identity & chain state
Address Intelligence
Classify supported targets, resolve network context and surface observable account or contract state without inventing existence, ownership or safety.
Evidence-led Web3 security intelligence
Security decisions,
with proof attached.
Koschei Web3 connects chain state, transaction context, spending authority, delegation and upgrade control into one accountable evidence path. What is observed stays observed. What is unknown stays unknown.

One intelligence surface
Built for the question after the scan.
Koschei is designed to answer not only what is this address?, but what code, permission and authority can materially affect it now?
Control plane
Authority Intelligence
Expose EIP-7702 delegation and standard ERC-1967 implementation, admin and beacon authority as bounded evidence.
Spending surface
Approval Intelligence
Model allowance, permit and transaction-scoped approval semantics without confusing permission with safety.
Execution context
Transaction Preflight
Inspect supported transaction context before execution and preserve the evidence that changed the decision.
Evidence maturity
Trust Vector
Keep claimed, observed, authorized, available, verified and finalized states separate instead of collapsing them into one score.
Evidence contract
Every conclusion keeps its boundary.
Premium security intelligence is not a prettier risk score. It is a better chain of custody for what the system actually knows.
Observed is not verified
An RPC response can establish observed state without silently becoming independent verification.
Permission is not safety
An allowance, delegation or upgrade authority is a control surface—not an automatic malicious verdict.
Absence is not proof
No standard proxy slot observed does not mean a contract is immutable or free of another upgrade mechanism.
