Smart Contract

Monetary Policy

The core contract related to rebase policy. This is where rebase operations are triggered, and SATO expansion and contraction decisions take place. The logic is decentralized and purely algorithmic based.
The SATO policy follows a step function mechanism to introduce uncorrelated price movements. A majority of the Stablecoins in the crypto market are correlated with Bitcoin’s price movement but SATO takes a distinctive new approach to solve this countercyclical price pressure. With step functions, the supply elasticity is kept in balance.

Monetary Policy Step function


The core contract related to the price oracle. This contract receives price updates from Oracle(s), and regularly works with the monetary policy to trigger rebases.
The oracle smart contract relies on the concept of Harmonic series as a tool for managing upcoming requests, and calculating median value. This is because all requests are made in a decentralized pattern. Mathematical Representation of a Harmonic Series:
n=11n=1+12+13+14+15+.{\displaystyle \sum _{n=1}^{\infty }{\frac {1}{n}}=1+{\frac {1}{2}}+{\frac {1}{3}}+{\frac {1}{4}}+{\frac {1}{5}}+\cdots .}


The core contract related to the SATO token. SATO is a modified version of the ERC20 token standard.
