Gyroscope is an all-weather stablecoin. It’s backed by a reserve portfolio that diversifies all DeFi risks - such as regulatory and governance risks - not just price risk. A Gyro Dollar can be minted for a price near $1 and can be redeemed for an amount near $1 in reserve assets, as determined through a new Automated Market Maker (AMM) design that balances risk in the system and concentrates liquidity around the $1 peg.

After a very successful testnet we are now looking forward to launching on mainnet.

We’re a team of around 6 and most of us are finishing or have completed PhDs in Computer Science and Mathematics. We are looking for a passionate smart-contract engineer to join us. You will be working closely with our other smart contract engineers to build and test Gyroscope’s smart contracts. We’re planning to release V1 in Q4 2021.
