Cryptographic Diagnostics for the Modular Era
Professional-grade troubleshooting for Account Abstraction failures, AI agent configuration panics, and legacy hardware recovery.
Interactive Diagnostic Suites
Air-gapped cryptographic utilities running entirely in local WebCrypto & browser memory.
ERC-4337 UserOp Decoder
Decode EntryPoint v0.6/v0.7 UserOperations, audit 2D nonces, calculate worst-case prefund collateral, and catch AA21/AA23/AA33 revert hazards.
Launch Decoder →WebAuthn Passkey Debugger
Audit local Windows Hello, Apple TouchID, and FIDO2 secure enclaves. Verify clientDataJSON hashing and User Verification (UV) flags.
Launch Debugger →Derivation Path Inspector
Simulate BIP44, BIP49, and BIP84 derivation tree schemas. Convert xpub, ypub, and zpub formats to resolve vanishing token balances.
Launch Inspector →BIP-39 Checksum Solver
Solve 24th-word checksums and recover mistyped or missing seed words across the 2048-word BIP-39 dictionary using local SHA-256 slicing.
Launch Solver →Technical Silos
Interconnected diagnostic clusters for rapid resolution.

Research & Diagnostic Methodology
LayerZeroFault is an independent technical repository dedicated to resolving cryptographic failure modes across hardware self-custody, Account Abstraction infrastructure (ERC-4337), and browser security enclaves (WebAuthn).
100% Client-Side Sandboxes
All diagnostic tools execute locally via browser WebCrypto APIs. Private keys and seed phrases are never accepted or transmitted.
Physical Testbed Verification
Troubleshooting procedures are tested on live hardware (Ledger Stax, Trezor) and EVM testnets prior to documentation.
