Narabi

Redemption-run sensing. Each day a sentinel reads the burns, mints and supply of one stablecoin population over a finalized window, steps an adaptive quantile tracker on the realized outcome, and publishes a hash-chained line anyone can replay. The gate's region for the class stays the committed static calibration until a pre-registered drift criterion fires.

Narabi attests: what it reads, how it works, what it hands on. The boxes are drawn in the style of the register status; the words come from this page’s data and the contract titles from the frozen schemas.

What is served today

The register’s served note for Narabi: a daily published timeline parsed by the site from the published files (its committed capture keeps each line's endpoint count only), and its attested flow carried into the served gate, both replayed by integration tests.

The served gate class stable-run-velocity-24h, keyed to the population narabi:persistence-v2@eip155:1/erc20:0x4c9edd5852cd905f086c759e8383e09bff1e68b3. The sentinel publishes at the UTC slots 00:30, 03:30, 06:30, 09:30. In the committed capture of the published files, the last window is the day 2026-09-23, and the tracker has stepped 6 times.

Contracts

The frozen contracts Narabi reads or writes, each with the keys it requires, read from the schema files. A contract with closed keys refuses an unknown key instead of ignoring it.
