Some great thread here

- Introduction to Cold Storage Best Practices: SatsDaddy compiles a list of cold storage best practices for cryptocurrency security, emphasizing it’s not financial advice or a product endorsement, urging individual research (Post ID: 1949604530191999454).
- Avoid Internet-Connected Devices: Never store seed phrases on internet-connected devices, assuming all are potentially compromised, and use hardware signing devices (e.g., ColdCard, Jade, Passport) for signing, with software wallets limited to watching/verifying (Post ID: 1949604533782323506).
- Diversify Wallets: Split cryptocurrency holdings into multiple wallets with separate seed phrases (e.g., 2.5 BTC each for a 5 BTC total) to limit exposure if one is compromised (Post ID: 1949604537104511174).
- Multisig Backup: For multisig setups, back up seed phrases, derivation paths, and quorum details, as all are needed to reconstruct the wallet (Post ID: 1949604537104511174).
- Shamir’s Secret Sharing (SSS): Use SSS to split seeds into shares requiring a threshold for recovery, ideal for geographic or social distribution, reducing single-vendor risk with diverse hardware (e.g., ColdCard, Jade, Passport) (Post ID: 1949604540472291502).
- Air-Gapped Signing: Operate signing devices in air-gapped mode using QR codes, microSD, or NFC, avoiding USB connections unless essential (Post ID: 1949604544247144888).
- Durable Storage: Stamp seeds and recovery info onto steel or titanium, as paper burns and plastic melts (Post ID: 1949604544247144888).
- Pre-Generate Addresses: Create multiple receive addresses (e.g., 12 for yearly DCA) to minimize signing device use (Post ID: 1949604549767147987).
- Own Node Usage: Use a personal node for transactions to avoid third-party node risks like lying, spying, or censorship (Post ID: 1949604549767147987).
- Transaction Verification: Check transactions via your node’s mempool before and after sending, not just the wallet interface (Post ID: 1949604556217761905).
- Software Integrity: Compile software yourself or verify signatures (e.g., Sparrow Wallet’s PGP verification) to ensure security (Post ID: 1949604556217761905).
- Trusted Tools: Use established, audited software/hardware, avoiding obscure options, and buy directly from manufacturers to avoid supply chain attacks (Post ID: 1949604561322127580).
- Seek Advice: Consult trusted individuals or communities via secure channels for big decisions, avoiding public forums (Post ID: 1949604574903275968).
- Hot Wallet Caution: Limit hot wallet funds to small amounts, treating them like pocket cash, not life savings (Post ID: 1949604574903275968).
- Geographic Separation: Store multisig/SSS shares in different locations (e.g., homes, banks) to enhance security (Post ID: 1949604580532081019).
- Passphrases and PINs: Add BIP-39 passphrases and strong PINs, but remember them to maintain access (Post ID: 1949604580532081019).
- Decoy Wallets: Set up believable decoy wallets with small balances for coercion scenarios (Post ID: 1949604586068598981).
- Duress Features: Use hardware wallet duress PINs to nuke wallets if threatened (Post ID: 1949604586068598981).
- Test Backups: Regularly test seed/SSS restorations in a safe environment to ensure functionality (Post ID: 1949604590367752653).
- Inheritance Planning: Document instructions for heirs, considering time-locked multisig, lawyers, or dead man’s switches (Post ID: 1949604590367752653).
- Avoid Photos: Never photograph seed phrases or QR codes due to cloud sync and metadata risks (Post ID: 1949604595187007792).
- On-Device Verification: Trust only the hardware wallet display for signing, not compromised apps or screens (Post ID: 1949604595187007792).
- Log Versions: Record firmware and software versions for future recovery (Post ID: 1949604599796466166).

- Understand Standards: Know wallet standards (e.g., BIP-39, BIP-85, SLIP-39) for compatibility (Post ID: 1949604599796466166).
- Avoid Browser Wallets: Use standalone apps (e.g., Sparrow, Specter) instead of risky browser-based wallets (Post ID: 1949604604427071741).
- Protect xpubs: Treat extended public keys (xpubs) as sensitive, sharing only when necessary due to balance/address exposure (Post ID: 1949604604427071741).
- Community Engagement: Acknowledges diverse risk approaches, invites additional tips, and encourages sharing/bookmarking for learning (Post ID: 1949604608772591927).
- Bonus Tip: Coins remain safe on-chain; consolidate UTXOs, back up seeds, and destroy signing devices if inactive long-term (Post ID: 1949611379704353125).
