Case Studies
Pion


A stablecoin with a token price of $1 by changing the total supply of tokens through a smart contract by rebase at a random time.
A second token convertible with the stablecoin at rate of 1:1, allows to fix the number of tokens pending the next rebase at a more favorable rate.
Stablecoin can generate income from yield farming by staking the LP2 Uniswap token.

Inflationary Staking


A project based on complex smart contracts that give users the ability to exchange, purchase and stake the token.
Receiving tokens is implemented in several ways:
• Exchange tokens at the rate of 1:1
• Free issuance of tokens from a snapshot with a Merkle tree check at a rate of 1:1
• Instant Token Buyback Auction with Uniswap to Maintain the Token Price
• Staking and receiving dividends due to token inflation.

Axion Dashboard


The dashboard visualizes financial statistics of the context of individual user wallets and time periods.
To implement instant access to all information on the project, a centralized database was developed that stores all information about events occurring on the contract, received in real time from the Ethereum network.
