Bitcoin’s self-custody UX fork: novice-friendly or expert-only?

Crypto executives are divided over whether self-custody was ever designed for beginners, as simpler Bitcoin custody designs are weighed against the security demands placed on users. Safe Labs CEO Rahul Rumalla told Cointelegraph, “We don’t expect every driver to be a mechanic, and we shouldn’t expect everyone who wants to own their assets to become a security expert,” saying easier self-custody could be critical to Bitcoin’s broader adoption. The ability to “be your own bank,” he said, remains one of Bitcoin’s defining features.

Michael Tanguma, CEO of Bitcoin custody provider Onramp, compared Bitcoin custody with personal computers in the 1970s, when users needed technical skills to assemble and operate them. “Self-custody was never designed with newcomers in mind,” he told Cointelegraph, saying simpler designs helped computers reach a wider audience and that Bitcoin custody now faces a similar challenge. Rumalla disagreed, saying self-custody was “always meant for everyone” and that “being able to own and control your assets is the whole point of crypto.” He added that self-custody “does not mean doing everything yourself.”

Recent incidents involving Ledger and Coldcard have exposed weaknesses in hardware wallets, widely recommended as one of the safest ways to hold crypto because they keep private keys offline. Implants in some Ledger devices stole recovery phrases, while a Coldcard firmware bug allowed attackers to recreate private keys and steal funds. Ledger’s early implant warnings deserved more action, Karpelès said. The Trezor Model One, the world’s first hardware wallet, was released in 2014.

Multisignature, or multisig, wallets require multiple keys to authorize transactions, but managing them can be difficult for beginners. “Traditional multisig implementations can introduce additional complexity involving signer coordination, key backups, recovery procedures, and transaction approvals,” said Justin Hutzler, chief technology officer of Synergy Network. A BitGo graphic contrasted single-signature and multisig setups. Multiple approvals also cannot prevent every attack, Rumalla said: several signers could still authorize a malicious transaction if they were all deceived by the same compromised interface.

Tangem says its seedless design simplifies self-custody by removing the need to manage a recovery phrase, but users must instead safeguard the physical devices that provide access to their funds. A private key is generated on one card, with backup copies stored on up to two additional devices. Tangem confirmed to Cointelegraph that losing every device would permanently lock users out of their funds. The company said it had received no reports of users losing all their cards.
