The short answer
A useful evidence file connects the story to verifiable events. Start with a chronology: first contact, advertised offer, payments, attempted withdrawals and the point at which you suspected fraud. Record dates with the time zone where possible. Separate your own observations from statements made by the other party.
What to check and preserve
For on-chain transfers, retain the transaction hash, network, asset, amount, sending address and receiving address. For bank or card payments, keep the original provider statement and payment reference. Export conversations where the platform supports it, preserving participants, timestamps and attachment names. Keep unaltered originals and use copies when highlighting passages.
Limits and important distinctions
Do not mistake a screenshot of a trading balance for proof that assets exist. Screenshots are context; provider records and public-chain transactions answer different questions. Minimise personal information shared during an initial review. Never put a seed phrase, private key, password or full card number into the evidence pack.
Checklist
- Write a dated event chronology.
- Keep originals separately from annotated copies.
- Record the chain as well as the transaction hash.
- Redact unnecessary third-party personal information.
