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.
Passkey & Cloud Recovery
Troubleshooting device-bound biometrics and cloud keychain escrow failures.
