#700 Self Custody DIscussion w/ Adam Lowe

— The typical user journey into Bitcoin and crypto begins with centralized exchanges, then progresses to hardware wallets as holdings grow and users seek greater control over their private keys.

— Arculus is a three-factor authentication hardware wallet using a physical card (storing keys on a secure element), biometric authentication, and PIN protection to secure crypto assets.

— Private key ownership is fundamental to independence and control in crypto; users who own their keys can make every decision about their assets without intermediaries.

— Common misconceptions include that managing private keys is difficult, that hardware wallet companies have access to users' keys, and that users can lock themselves out permanently—all are false with modern systems.

— Best practices for seed phrase management include storing them analog (ink on acid-free paper), keeping them in a vault, splitting them across multiple secure locations for larger holdings, and ensuring trusted loved ones know how to access them.

— Regulatory compliance is the biggest challenge facing hardware wallet and crypto custody providers, more so than technical limitations.

— When setting up a portfolio split, keep the amount you actively trade on a centralized exchange, and move the rest to one or more hardware wallets—consider separate wallets for different asset types (Bitcoin, Ethereum, etc.) for cleaner mental accounting.

— Before transferring crypto between exchanges and hardware wallets, check fee structures carefully; moving ERC-20 tokens can be extremely expensive, so stablecoins like USDC may be more cost-efficient for moving value.

— Store seed phrases in multiple analog locations (attorney, safe deposit box, vault) and explicitly designate inheritance in your will; do not include the actual phrase in the will document itself since it may change over time.
