What Is a Cryptocurrency Wallet?
Understand what wallet software actually stores, how transactions are signed, and how custodial and self-custody models differ. Read the wallet guide.
Seed Phrase vs Private Key
See why the mnemonic, binary seed, master key, and child private keys are related but not interchangeable. Compare the concepts.
Protect and recover access
How to Store a Seed Phrase Safely
Build a backup plan around theft, fire, water, accidental loss, phishing, and the need to recover years later. Review storage options.
What Happens If You Lose a Seed Phrase?
Use a decision tree based on whether the original wallet is still accessible and whether another valid backup exists. Review the recovery scenarios.
Common Seed Phrase Scams
Recognize fake support, phishing pages, malicious wallet apps, remote-access requests, and false “verification” procedures. Learn the warning signs.
Choose a wallet setup
Hot Wallet vs Cold Wallet
Compare connectivity, convenience, attack surface, backup requirements, and common use cases without assuming that one setup is automatically safe. Compare wallet types.
Never submit a real wallet backup
Maru Supply does not provide wallet recovery services. Never send a seed phrase, private key, wallet file, PIN, or remote-access code through a contact form or email.
