Testnet only. No audit, not run on mainnet. The omens in the demo Kizashi are drill omens: nothing here means a production key has broken.

KAIGEN

When keys
break, adapt.

KAIGEN protects NEAR accounts from the day quantum computers break today's signatures. When a public omen key is broken, every opted-in vault locks itself into post-quantum-only mode.

One signed claim moves the era.

  1. Omens

    Omens are public keys that nobody holds.

  2. Prove

    Anyone can prove one broke with a signature.

  3. Trip

    Vaults delete classical keys when the era changes.

  4. AdminBackup required

    A post-quantum admin key stays in control.

  • Automatic

    No oracle, no admin and nobody online. The contracts trust only signatures.

  • Bounded

    A broken classical key can only spend its daily limit.

  • Daily

    Hinomi publishes the exposure. Every day.

  • Open

    Anyone can run a keeper, rebuild the index or trip a vault.

  • Verifiable

    Check the claims yourself. One command, against mainnet.

Claim, trip, kaigen. One signed claim.

Permissionless trip

Anyone, a keeper or the app can call trip on a vault. Nothing in between needs trust.

Signature-proven omens

An omen's death is proven by a signature that the chain verifies. There is no oracle and no admin, and the contracts are locked after deploy.

Bounded loss

A broken daily key can send only up to its limit, or queue a withdrawal the admin can cancel within the delay. That holds even if no omen ever breaks.

A bounty on real addresses

The omen keys also hold bounties at a NEAR implicit account, a Solana address and a Bitcoin Taproot address. Anyone can top up the bounty.

Self-custody

KAIGEN never holds your keys or your funds. The admin key is made in your browser, and you save an encrypted backup before the vault is created.

Honest limits

Validator keys stay classical until about the end of 2027, and an omen proves a curve can be broken, not who broke it. The limits are stated up front.

Omens

Two curves, two omens.

ed25519-omen covers NEAR account keys. secp256k1-omen covers Bitcoin and Ethereum. Each is a public key derived from a published seed, so nobody holds it.

Daily

Watch the exposureas it changes.

Hinomi publishes, every day, how much value on NEAR sits behind classical-only keys and how much is already post-quantum, with history. It is named for the Edo fire-lookout tower.

  • Classical-only value
  • Post-quantum value
  • Public history

Claims, trips and weekly fire tests are events on mainnet, with transaction hashes published, so you can check what happened instead of taking our word for it.

Bounded

Bounded loss.Calm days.

Mamori limits what a classical key can ever do, and a false alarm moves no funds, it only locks a vault into post-quantum-only mode. KAIGEN has no admin and no upgrade path after deploy.

  • Own your admin key
  • No account needed
  • No lock-in
  • Verify it yourself

Kizashi: the omen registry

Omens are public keys nobody holds, each derived from a published seed by hashing to a curve point. A valid signature from one proves that curve's keys can be broken. Kizashi checks it on-chain, marks the omen dead forever and raises the era.

ClaimKaigen

Mamori: the guard on every vault

A classical daily key can only send within a 24 hour limit or queue a withdrawal the admin can cancel. When the era reaches kaigen, anyone can call trip and the guard deletes the classical keys.

Hinomi: the daily exposure index

Each day it reads access keys and balances for the top NEAR accounts and every vault, and publishes how much value sits behind classical-only keys against post-quantum keys.

Kaigen: the lockdown

Classical keys are removed and only post-quantum keys remain. Weekly fire tests run the same path on drill omens and drill vaults, so the lockdown is rehearsed before it is ever needed.

Frequently asked questions

Is KAIGEN safe?

Only you hold the admin key, and a broken classical key can spend only its daily limit. KAIGEN has no admin and no upgrade path after deploy. It has not had an outside audit, but you can check the claims yourself against mainnet with one command.

What if I lose the admin key?

Daily keys can still queue withdrawals while the era is calm. After kaigen, funds are stuck, which is why an encrypted backup is required before the vault is created. See the backup step and the limits.

Which networks does KAIGEN cover?

KAIGEN targets NEAR mainnet and NEAR's ML-DSA-65 post-quantum keys, live since network upgrade 2.13 on 20 July 2026. Other chains appear only as bounty addresses.
