🔒 Local account — your data stays on this device only. This is not a cloud account; use a unique password you don't use elsewhere.
⛔ THE ONE RULE: Never type your seed phrase or private key into this app, any website, or any "support" chat — ever. No legitimate service will ever ask for it. This app deliberately has no field for secrets, and it will refuse text that looks like a seed phrase.
🎮 Do / Don't Trainer
Ten real-world situations. For each one, decide: is this SAFE practice or a DANGER? The trainer works as a guest — log in to save audits and your wallet inventory below.
🧾 Wallet Self-Audit
Tick what is genuinely true for the wallet(s) holding money you can't afford to lose.
0/100
Answer the audit to see your grade.
🗂️ My Wallet & Account Inventory (names & types ONLY)
A map of where your crypto lives — so nothing is forgotten — without storing anything an attacker could use. Allowed: wallet/account names, type, and general notes ("used for savings", "opened 2024"). Forbidden: seed phrases, private keys, passwords, full addresses with balances. The form will reject text that looks like a seed phrase.
🎓 The Principles Behind the Trainer
Seed phrase = the money. Whoever has the 12/24 words has the wallet, on any device, forever. Screenshots, cloud notes and "support agents" are all theft vectors.
Verify on the device, not the screen. Malware can swap addresses in your clipboard or browser. Hardware wallets exist so the address you approve is the address on a screen malware can't touch.
Small test first. New address, new exchange, new network? Send a tiny amount and confirm arrival before moving real money.
Backups are physical security. Paper burns, metal survives; one copy in one place is a single point of failure — but every extra copy must be guarded like cash.
