Why 2025’s Hacks Require New Rules
2025 has seen a surge in AI-powered phishing and smart contract exploits. Hackers are no longer solo coders — they’re running sophisticated, well-funded operations.
🔥 Quick Takeaway: Over 63% of wallet breaches in 2025 occurred through mobile-based attacks and SIM jacking, not brute force.
Traditional methods like basic two-factor authentication (2FA) and exchange-held wallets are no longer enough. It’s time to go beyond the basics and adopt multi-layered defenses.
🔐 Cold Storage in 2025: Why USBs Aren’t Enough
Cold storage for crypto is still your best line of defense — but 2025 requires smarter hardware and protocols.
Best Options for Cold Storage:
- Ledger Stax – E-ink touch screen, Bluetooth, and improved passphrase protection
- Trezor Safe 3 – Open-source and supports Shamir Backup
- Arculus Card – Tap-to-pay-style cold wallet with biometric lock
Key Practices:
- Always wipe your cold wallet after each use
- Use two separate hardware wallets for assets over $50,000
- Don’t store your recovery seed in your home — use a bank vault or fireproof capsule
🔐 Pro Tip: Use a Faraday bag to block Bluetooth/NFC on your hardware wallet during travel.
🛡 Multisig Wallets: The Gold Standard?
A multisig wallet requires multiple private keys to sign transactions — meaning no one person (or hacker) can access your funds alone.
Benefits of Multisig Wallets:
- Prevents single-point failure
- Enables shared custody (great for families or DAOs)
- Adds protection even if one key is compromised
Top Multisig Tools in 2025:
- Casa – Simple multisig for Bitcoin with inheritance setup
- Gnosis Safe – Great for managing DAO or team wallets
- Sparrow Wallet – Advanced, open-source option for multisig coordination
🧠 Quick Takeaway: Most crypto thefts happen when users lose a single private key. Multisig fixes that.
🧾 Crypto Inheritance Planning Made Easy
Most crypto is lost forever when users die without a plan. In 2025, inheritance planning for crypto is finally user-friendly.
Modern Inheritance Tools:
- Casa Covenant – Inheritance with time-locked wallet transfer
- Safe Haven – Legal-smart contracts for family access
- TrustVerse – AI-powered digital estate management
Steps to Secure Inheritance:
- Set up a multisig wallet with one key held by a lawyer or trustee
- Use a smart contract that auto-triggers after inactivity
- Store your instructions in a dead man’s switch or secure vault
⚠️ Note: Heirs must still complete KYC verification in most services to receive assets.
