Hypervolic

These docs describe Hypervolic's production exchange, not the prototype. The prototype at prototype.hypervolic.com is a paper-trading demonstration on separate code: it trades no real money, and it differs from what is described here in places. Its options, for one, are American-style rather than European.
Hypervolic is an exchange for options on prediction markets: calls and puts on the price of an outcome, which is a probability between 0 and 1. Options are European and cash-settled in USDC, with a multiplier of 100.
  • Fully secured. Every short holds its worst case in cash from the moment it opens. No credit, no margin calls, no liquidations.
  • Non-custodial. Your USDC sits in a settlement contract on Base that checks every fill itself, and that you can withdraw from without the exchange.
  • Signed orders. Every order is EIP-712 data signed by your wallet or a key you registered, and the contract verifies the signature again before it pays.
