SeedForge
A local toolkit for structured BIP39 candidate research, public cryptographic puzzles and authorized wallet-recovery experiments.
Public releaseSeedForge v0.2.x is being prepared for a clean public package.Developer on GitHubNo cloud processing. Seed material stays on the computer running the tool.
GPU-oriented
Designed for large, explicitly defined candidate spaces where GPU acceleration can materially reduce research time.
Reproducible runs
State files, explicit patterns and deterministic candidate sets make long research sessions easier to pause, audit and resume.
BIP39-aware
Workflows are built around BIP39 word lists, checksum-valid phrases and standard derivation paths.
Public puzzles
Useful for legal, public cryptographic challenges where candidate constraints are known and the target is intentionally published.
Authorized recovery
Also suitable for research on wallets you own or are explicitly authorized to recover.
Responsible use
SeedForge is intended for public puzzles, education, benchmarking and recovery of wallets you own or have explicit permission to work on. It is not presented as a tool for accessing third-party wallets.
What will be published
The public package will include installation instructions, supported GPU requirements, command reference, examples using synthetic/test data, checksums and release notes. Publishing will happen only after the current research build is cleaned of puzzle-specific state and private working files.
Structured search rather than blind guessing
SeedForge is intended for situations where some facts are already known: fixed mnemonic positions, constrained word pools, checksum rules, derivation paths or an intentionally published target. Those facts can be expressed as reproducible candidate spaces instead of manually trying phrases.
Reproducibility for long runs
Large searches may run for hours or days. State files and explicit modes make it easier to document what was tested, pause work and avoid repeating the same candidate set. Public examples use synthetic or deliberately published puzzle data.
Local security model
The website does not provide a seed-upload service. Sensitive recovery material should remain on a computer you control, ideally offline or otherwise isolated when real wallet data is involved.
