Cryptography Protects Wallets from Rogue Providers with Trust-Minimized Simulation Approach

Transaction simulation is critical for wallet security, but current approaches require trusting RPC providers for state data. We propose a trust-minimized approach using Merkle Patricia Trie proofs and multi-node consensus to cryptographically verify prestate before execution. This eliminates reliance on single RPC providers while remaining practical for production wallets and increasing user safety.
