Hardware-wallet status
These docs do not certify Ledger or any other consumer hardware wallet for Monolythium. Do not infer support from a device’s general algorithm roadmap, a host-side adapter, or historical product prose.
A valid integration would need device-side support for the exact released signing and key-derivation contract, trusted display of chain identity and transaction intent, independent test vectors, firmware provenance, wallet integration, recovery behavior, and security review. Host-side re-signing with a separate software key does not turn a classical hardware approval into hardware custody of the chain-valid key.
No consumer hardware-wallet flow, exchange appliance signer, or real-funds custody path is released by this page. Testnet 69420 is value-less and resettable.
