12 printable one-page cheat sheets for people who actually move funds onchain: wallet safety, chain IDs and bridges (Base, Arbitrum, OP Mainnet, Solana, Bitcoin), gas fees decoded, official stablecoin contracts, DeFi risk ladder, the 10 scam patterns to memorize, pre-entry trading checklist, tax log template, testnet faucets, explorer reading, rebalancing rules, and an emergency card for a compromised wallet.

Print-ready in A4 and US Letter. Black-and-white friendly with one teal accent, so they survive any office printer. Tape them above the desk and stop trusting memory for things like which bridge is the official one.

Educational reference only, not financial advice. Every address and link is meant to be re-verified on official sources before you send anything.

Inside: A4 and Letter folders with the same 12 numbered PDFs, 01-wallet-safety through 12-emergency-card, each under 5 KB. Print at 100% scale, no fit-to-page. Print sheet 12 (Emergency Card) twice, one taped above the desk and one with your backups.
