Noether

Noether moves perpetual futures fully onto Stellar, with orders, matching, liquidation and funding payments all executed by Soroban smart contracts rather than matched off-chain and reported back.

A purpose-built Noeracle price chain supplies a mark price per market and caps price staleness at 60 seconds, rejecting fills beyond that so stale quotes cannot be exploited. Contracts support up to 10x leverage, with maker and taker fees of 0.020% and 0.050% that step down by volume tier, a 10 USDC minimum collateral per position and a $100,000 notional cap. On the developer side a REST and WebSocket gateway ships with TypeScript and Python SDKs; the gateway only assembles transactions, signing stays in the user's wallet and keys never reach the server. The gateway exposes both market-data subscriptions and order entry, covering depth and funding rates across 14 open markets for programs that compare prices between venues.
