If the maker misses a security patch deadline, the device's current owner can collect. Sureplate is a security warranty that is its own escrow: the maker's bond is locked inside the device's NFT on NEAR, and it follows the device when it is resold.
Four rules, all enforced by one contract on NEAR. No insurer, no claims desk.
| Severity | Share of the unit's bond |
|---|---|
| Low | 10% |
| High | 25% |
| Critical | 50% |
The maker can dispute it once, for a fee equal to the reporter's stake. The clock pauses and the line's arbiter rules. In the demo that is a Sputnik DAO council vote. Upheld: the fee goes to the reporter and the clock restarts. Rejected: the reporter's stake goes to the maker.
The maker takes back what is left of the bond, after anything still owed to the owner is paid first. The passport stays with the owner as the unit's permanent record.
Stated plainly, so you know what you are looking at.
The contract, the bond escrow, the patch clock, the payout to the current NFT holder, resale, disputes through a DAO vote and the end-of-support release all run on NEAR testnet. Every state on this page is read from the chain.
Testnet NEAR, a made-up maker, and patch windows of seconds instead of days. No real manufacturer has bonded a product. The contract is not audited.
Advisory verification: check the public vulnerability record against the unit's SBOM inside an attested enclave, so a valid advisory needs no vote. Arbiter trust: a council of CERTs, auditors and insurers with their own stake, instead of three demo accounts. Then a stablecoin bond.
