Why Social Recovery Schemes Undermine Non-Custodial Promises

Argent's initial model relied on centralized Guardian nodes operated by the team. When they deprecated V1, users faced a forced migration. This demonstrated that protocol-level admin keys can unilaterally alter or sunset 'non-custodial' systems, a power antithetical to true sovereignty.

While multi-sig, Safe's default social recovery setup often delegates to enterprise providers like Coinbase Cloud or Web3Auth. This creates rent-seeking intermediaries and KYC gateways for recovery. The security model degrades to the weakest approved guardian, often a regulated entity.

Schemes requiring pre-designated social or legal heirs (e.g., Safe{Wallet} Inheritance, Casa) legally enshrine external claims on private keys. This blurs the legal line between possession and ownership, inviting probate courts and third-party adjudication into what should be cryptographic self-sovereignty.

Account Abstraction's bundler and paymaster model introduces new centralization vectors. Social recovery logic often depends on these off-chain actors. If major bundlers like Stackup or Alchemy censored recovery transactions, users could be permanently locked out.

MPC wallets (Fireblocks, ZenGo) split key shares among providers, but recovery typically requires the provider's cooperation. This is functionally custody with extra steps. The provider's HSM infrastructure and governance become your single point of failure.

Starknet's native account abstraction hardcodes social recovery logic at the protocol level. This creates vendor lock-in and protocol-level opinionation about security models. A bug in the standard recovery contract could affect all wallets on the network.

Recovery relies on a pre-defined, mutable list of guardians (friends, institutions). This creates a persistent attack surface and a social engineering honeypot.\n- Key Risk: Guardian compromise or collusion defeats the wallet's security.\n- Key Consequence: Shifts trust from cryptographic proof to human reliability, a historically fragile system.

Most implementations require publishing guardian addresses or relationships on-chain, permanently linking social graphs to financial identities.\n- Key Risk: De-anonymizes users and exposes network topology.\n- Key Consequence: Enables chain analysis and targeted phishing, directly contradicting privacy-centric wallet promises.

Recovery requires guardians to be available and honest at the exact moment of need. This introduces liveness failure risks and opens the door to governance attacks on the recovery protocol itself.\n- Key Risk: Protocol upgrades or guardian apathy can brick recovery.\n- Key Consequence: Users are subject to the political will of the guardian set or DAO, a form of soft custody.

True self-custody solutions like Multi-Party Computation (MPI) or hardware-secured enclaves distribute trust cryptographically, not socially.\n- Key Benefit: No single entity can unilaterally recover or steal funds.\n- Key Benefit: Eliminates the social graph footprint and on-chain privacy leak.

Framing social recovery as a 'user-friendly' security upgrade is a marketing sleight of hand. It trades the absolute security of a private key for the perceived convenience of a recoverable account.\n- Key Risk: Obscures the fundamental trust shift from user to network.\n- Key Consequence: Creates a false sense of security, leading to higher-value assets being stored in effectively custodial arrangements.

A defined, on-chain guardian set is a regulator's dream. It provides a clear map for enforcement actions, allowing pressure to be applied to centralized guardians (e.g., Coinbase, Wallet providers) to censor recoveries.\n- Key Risk: Turns a decentralized ideal into a compliance-friendly checkpoint.\n- Key Consequence: Paves the way for travel rule enforcement and blacklisting at the wallet layer, defeating censorship resistance.
