Options DEX · live on Base mainnet

Standardised options.
Fully on-chain.

Every option is issued on one shared, standardised grid of strikes and expiry dates, so liquidity pools together instead of scattering across thousands of one-off contracts. Create and trade fully on-chain options on any asset Chainlink prices — no approvals, nothing off-chain.

Built-in options DEX Every option has its own USDC swap pool, open until expiry
One shared grid Standard strikes and weekly expiries concentrate liquidity
Chainlink-priced Any listed feed can carry options, permissionlessly

How it works

01
Mint an option Deposit USDC as collateral and you get two options back: the buy option and the sell option. Deposit $100, get $100 of each.
02
Sell the side you don't want Keep the option that matches your view and sell the other one for USDC — or skip minting entirely and just buy the option you want from someone else. Each option has its own pool.
03
Collect at expiry On expiry day a Chainlink price decides how the collateral is divided between the two options. Claim your share whenever you like — nobody else has to act first.

Options can be created on any Chainlink price feed, by anyone, with no approval. Strikes and expiry dates come from one shared, standardised grid, so traders meet in the same markets instead of scattering across thousands of one-off contracts.

How it works in detail

Why trade here

Options are a $10+ trillion market in traditional finance, and on-chain they are still scarce, illiquid and permissioned. Stochastic Finance makes them issuable by anyone, on any Chainlink feed, with every position fully backed by the collateral behind it.

Leveraged exposure

An out-of-the-money option costs a fraction of collateral and pays a multiple of it if the move lands — leverage without a liquidation price

Hedge your risks

Cap downside on a position you already hold. Your maximum loss is the collateral you posted, known before you trade

On-chain assets

Positions are ERC-1155 tokens on a public ledger — transferable, composable, and tradeable anywhere that supports the standard

Fee distributions

Exercise fees are the protocol's revenue line, earmarked for STFIN holders once the token launches. Swap fees stay with liquidity providers

Options DEX

An options DEX with a pool for every option

Stochastic Finance is a decentralised exchange for options on Base. Every option leg trades in its own swap pool against USDC, so you can buy or sell a position at any moment before expiry, straight from your wallet. No order book to fill, no market maker to quote you, no account to open.

Swap any option for USDC

Each leg has its own constant-product pool, the same curve as Uniswap V2. Buy with USDC and sell back for USDC, any time until expiry.

A fee that tracks fair value

The router prices every option from the live Chainlink spot. Trades near fair value pay the 2% floor. Trades that push a pool far from fair value pay more, so stale prices can't be farmed.

Liquidity providers keep every fee

All swap fees stay in the pool, with no protocol cut. LP shares are transferable tokens, and anyone can open a pool for any option on the grid.

You set the worst case

Every swap carries a minimum-out guard and a cap on the USDC it may spend. If the price or fee moves past it before your transaction lands, the swap reverts and nothing moves.

Open Swaps How trading works Provide liquidity

Option legs are standard ERC-1155 tokens, so you can also send them to any wallet or trade them on any venue that supports the standard. Read how the dynamic swap fee is calculated.

STFIN airdrop

Early users get the first STFIN

STFIN is the protocol's native token, with a fixed supply of 10,000,000 and no further minting. 1% of that supply is set aside for the people who used the protocol first — not for buyers, and not for anyone who showed up after the snapshot.

Write options

Post USDC collateral and mint a position. Every option in existence started this way.

Trade an option

Buy or sell either side of an option on the AMM. Volume counts toward eligibility.

Provide liquidity

Seed a pool and keep it there. Depth held over time is weighted most heavily of the three.

Start qualifying

Eligibility is measured from on-chain activity on Base mainnet. The snapshot date and the full criteria will be published here and to the newsletter before the snapshot is taken.

The token is not live yet. No STFIN contract has been deployed and there is no sale, presale or allowlist. Any token, pool or form claiming otherwise is not ours — the airdrop will be announced from this site and our own channels only.
