In a recent blog post on Reddit, Ethereum co-founder, Vitalik Buterin emphasised on self-custody of funds through Multisig wallets and Social Recovery wallets to ensure the safety of funds, instead of handing them over to a “centralized entity”.
His statement is coming amidst the ongoing devastation in crypto-friendly banks such as Silicon Valley Bank, Signature Bank, to name a few, and the collapse of centralised crypto firms including FTX, Voyager Digital, and others.
Vitalik stated in a blog post, “I use a multisig wallet personally to store the bulk of my funds, as does the Ethereum Foundation.”

Multisig wallets are digital wallets that require the approval of all authorised members to sign transactions through signature. It means no single owner can get access to funds. On the other hand, funds locked in social recovery wallets can be recovered by a group of keys held by other people if the main key gets lost.
He said social recovery wallets are more incorporative than multisig with ERC-4337 account abstraction and upcoming wallets like Soul Wallet. ERC-4337 is the recently deployed smart contract on the Ethereum network and is expected to boost mainstream crypto adoption.
Both types of wallets rely on “guardians,” which are individuals or entities holding keys that can approve transactions or recover funds.
“My recommendation will be to use social recovery for hot wallets that store a small portion of a person or organization’s funds, and multisigs for cold wallets that store a person or organizations’s savings,” he added.
In a post, he shared guidance to choose guardians, in which he stated
- Multisig wallet should be controlled by at least 1 guardian,
- Guardians should not have correlations to reduce the risk that they collude
- Instruct guardians to ask a security question before confirming transactions
- Guardians should be quick if users are involved in degen” stuff
- Perform test operations for guardians to ensure that guardians haven’t forgotten or lost their accounts.
