Safe's smart account infrastructure secures $60B+ in TVL while handling over $1 trillion in cumulative transaction volume. Co-founder, Richard Meissner reveals how Safe is rebuilding its collaboration layer from scratch—replacing centralized transaction services with encrypted on-chain queues while preparing smart accounts for post-quantum cryptography through deterministic deployment standards.
Topics discussed:

Safe Harbor's permissionless transaction queue migrating from contract storage to event-based and blob storage to reduce costs while maintaining consensus-layer availability guarantees
Validator network architecture in frictionless queues performing spam protection and integrity checks on encrypted payloads before paymaster-sponsored on-chain submission
Asymmetric encryption implementation using shared keys among Safe signers to hide transaction intent, with blob storage providing shorter data availability windows than permanent contract storage
ERC-7955's elimination of nonce-dependent deployment attacks by publicly exposing factory private keys through EIP-7702, preventing address spoofing exploits that caused historical fund losses
Four-layer security methodology: audits during development, dual auditors from different firms at release, formal verification with Runtime Verification and Certora, and $1M+ bug bounties during phased rollouts
Phased production deployment strategy starting with foundation Safes as front runners for months before prompting user upgrades to new contract versions
Smart account migration pathways for post-quantum algorithms using passkey implementations (non-native curve support) as proof-of-concept for lattice-based signature schemes
Organizational structure separating Safe Labs' enterprise custody focus from Research team's permissionless protocol development to balance adoption velocity with decentralization roadmap
