Marco Rossi

Marco covers wallet security and self-custody for Kripzen. A long-time developer who has audited smart contracts and wallet software, he writes about the practical decisions that keep funds safe — seed phrase storage, hardware wallets, and the trade-offs between custodial and non-custodial setups — and turns it into clear advice rather than jargon for its own sake.

He focuses on the realities readers care about: how to evaluate a wallet or exchange's security claims, what a proof-of-reserves attestation actually proves (and doesn't), gas fees and network confirmation times, and the checks worth making before moving any meaningful amount of crypto. He keeps the tone measured and the security-first message up front.
