Sphincs Minus V2.
a post-quantum flavored mint token with a plain on-chain attestation gate.
loading mint progress...
Sphincs Minus is a meme coin experiment built around a fast EIP-712 mint path. A backend issues a short-lived attestation for your address and a unique pkHash; the contract verifies that signature and mints in the same transaction.
The point is not to pretend the chain verifies a full post-quantum proof. The point is to make the trade-off legible: off-chain key ceremony, on-chain supply limits, immutable mint rules, and public records.

why
The contract is intentionally small: no admin, no proxy, no pause, no OpenZeppelin dependency. The backend can issue or withhold attestations, but it cannot expand supply, change price, or redirect a valid claim to a different recipient.
how it works (30 seconds)
- press generate key. server generates your attestation.
- type your eth address. press sign + get attestation. backend signs an EIP-712 attestation.
- press mint now. your wallet sends one transaction (~60k gas). contract ecrecovers the attestation and mints 500 $SPHINCSV2 to you in the same block.
trust
- contract is immutable - no admin, no proxy, no pause.
- team allocation = 0. the 1,000,000 $SPHINCSV2 team reserve was sent to 0x...dEaD and is permanently unspendable.
- backend can delay your mint but cannot mint to a wrong address - your address is inside the signed message.
- backend cannot mint extra supply - the contract caps public mint at 10M.
- every (pkHash, attestation) tuple is retrievable at /records. anyone can re-verify.
- all source code (contracts, backend, frontend, whitepaper) is MIT-licensed at github.
