🟒 The simple version

Plain English β€” no jargon. Start here.

One sentence

Polynomial Finance is a structured options vault protocol on Optimism using Synthetix as the options backend β€” similar to Ribbon Finance's Theta Vaults but native to the OP/Synthetix ecosystem β€” automatically selling weekly options to earn theta (time decay) yield.

Options vaults on Optimism

Deposit ETH β†’ Polynomial's covered call vault automatically writes weekly ETH calls on Synthetix β†’ collects option premiums. If ETH stays below strike: vault keeps all premiums. If ETH rallies above strike: options exercised, vault delivers ETH at lower strike price (caps upside). Similar to Ribbon's Theta Vaults but Synthetix-powered. ~100M POLY governance. Is POLY legal in India? Yes. 30% tax, 1% TDS apply.
