How it's built

You don’t need this page to use Numera. It’s here because the guarantees mean more when you can see how they’re held in place.

​

Four parts

Your device. Holds your passkey, creates your trading accounts, and approves every trade. It’s where the connection between you and your positions lives — and the only place it exists. The private pool. Where funds sit between deposits and trades. Money enters, and reaches your trading accounts privately. The blockchain contracts. The market itself: holding funds, calculating prices, recording positions, paying out. Permanent and unchangeable, including by Numera. Numera’s service. Reads the blockchain, serves the site, streams live prices, and covers network fees for you.

​

What holds each guarantee

The pattern is consistent: every promise is enforced by the blockchain or by your own device. Numera’s service makes the product fast and pleasant to use, and the guarantees stand on their own underneath it.

​

Built so the guarantees hold themselves

Funds live on the blockchain. Trades are approved on your device, and the system that submits them is restricted at the blockchain level to exactly five trader actions — buy, bet against, sell, close, claim. Market creation, settlement and administration sit outside it entirely. Privacy is structural. There’s no record joining people to positions. Not encrypted, not permissioned — simply never created, which is a stronger position than protecting one. Market terms are permanent. Question, deadline, outcomes and fee ceiling are written to the blockchain at creation with no mechanism to revise them. Exits always work. Claiming is a direct action against the contracts. Even an emergency pause affects only new trades, leaving exits and claims fully available.

​

Network fees, handled

Numera’s service takes trades you’ve approved and submits them, covering the blockchain cost. It’s deliberately narrow: one contract, five actions, and no ability to create a trade you didn’t approve. That keeps it a convenience layer with no access to your funds — the security of your position rests on the blockchain, not on this service. The reason it works this way is privacy as much as convenience.

​

Open by default

Every market, price, trade and payout is recorded publicly. Every number on the site can be checked against the blockchain directly.
