A computederivatives market.

AI teams rent GPUs at floating hourly rates, with no instrument to lock them in. Tesselex lists cash-settled forwards, options and basis swaps on GPU-hour rates — priced against a multi-source rental index, cleared on-chain, custody never leaving your wallet.

Trading is invite-only during the guarded launch. Every number below is public and needs no invite.

Each tier mark is posted on-chain by a signer quorum (house-held today; independent signers are Phase 2), movement-capped, and published only above a minimum count of independent sources. A tier that loses quorum freezes: it never fabricates. The composite and the H200−H100 basis are derived from those tier marks, not polled directly. Per-tier index status and settlement grades.

Clearing & solvency.

The clearing pool must equal the sum of every account, to the wei, at every block. This page re-derives that identity in your browser from the published snapshot, reports whether it closes, and states the snapshot's age. Same endpoint, no key required.
