research: key management design for Starknet & Aztec shielded asset i…#8221
Conversation
…ntegration Deep research on how BitGo's 2-of-3 key management would work for Starknet and Aztec (shielded transactions), with Midnight as reference. Key findings: - Starknet: on-chain contract multisig via Argent (secp256k1 compatible, no HSM firmware changes needed) - Aztec: custom multisig account contract with signing keys externalized via AuthWitnessProvider (signing key NOT in ZK circuit) - Both chains decouple spending authorization from ZK proof generation, unlike Midnight where spend key must be in the ZK circuit - Viewing keys can be single-sig in BitGo PXE, fee keys separate - TACEO collaborative SNARKs emerging as future option for deeper privacy https://claude.ai/code/session_01FrnL5et6RD2P8vpD46epsy
