What is a social recovery wallet?

A social recovery wallet is a crypto wallet that can be recovered with help from people or devices you trust, called guardians. Instead of one secret that controls everything forever, it separates daily use from recovery. If you lose your phone or key, your guardians can approve a switch to a new key, and the funds stay where they are.

How does a social recovery wallet work?

In his January 2021 essay, Vitalik Buterin described the setup. There is a single signing key that approves transactions, so in normal use the wallet feels like any other wallet. There is also a set of at least three guardians, and a majority of them can cooperate to change the wallet's signing key. The owner's signing key can add or remove guardians, but only after a delay, which he suggested is often one to three days.

If the owner loses the signing key, they contact their guardians and ask each to sign a special transaction that registers a new key in the wallet contract. Buterin wrote that for each guardian this can be about as easy as making a trade on a decentralized exchange. Because these rules are enforced by a smart contract, social recovery is one of the features enabled by account abstraction.

Who can be a guardian in a social recovery wallet?

Buterin listed three common choices. Guardians can be other devices or paper backups held by the owner, friends and family members, or institutions that sign a recovery only after checking the owner's identity, for example by phone or email. Mixing types spreads the risk, since no single guardian can act alone.

Is a social recovery wallet safer than a seed phrase?

It trades one risk for another. A seed phrase is a single point of failure. Lose it and the funds may be gone, and anyone who finds it can take everything, as described in what happens if you lose your seed phrase. Social recovery spreads that power across several people, so losing one key is survivable. The risk moves to the guardians. If a majority of them colluded or were all compromised, they could take over the wallet, which is why the design relies on a majority and a delay.

Buterin's argument was that for most people, losing access is a bigger danger than theft by trusted guardians. Smart contract wallets also depend on the contract code being sound, so an audited, widely used wallet design matters. Recovery features and guardian rules vary between wallet providers, so the details depend on the specific product.
