Name the decision
Write the exact transaction, onboarding, accounting, legal, or treasury question. Record who will make the decision and by when.
A practical, source-first checklist for deciding what an EVM address can support, what remains unknown, and whether deeper work is justified.
Free to use · No registration required · Never enter a seed phrase or private key
Write the exact transaction, onboarding, accounting, legal, or treasury question. Record who will make the decision and by when.
Copy the full address, network, and source. Check the address on the relevant explorer. Never request credentials, seed phrases, or private keys.
Record first and latest visible activity, dormant periods, bursts, transaction count, and whether the address is a contract.
Surface concentrated inbound and outbound value, recurring paths, bridge activity, and transfers relevant to the stated decision.
Cite each public label to its source. Treat labels as third-party claims unless ownership or control is independently established.
State unresolved ownership, purpose, source-of-funds, identity, and off-chain questions. Avoid “safe,” “clean,” or certification language.
Document whether the evidence supports proceeding, asking for context, involving a qualified professional, or commissioning deeper analysis.
Describe only what is visible on the public record, with the UTC timestamp and direct explorer link.
Explain why it matters to the decision, using calibrated language and a confidence level.
Record the identity, intent, or off-chain context the observation does not establish.
Write the smallest additional fact that would materially change the decision.
