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.
Features
- Multicomponent system
- Stablecoin
- Liquidity Pool Staking
Stacks:
- Solidity
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.
Features
- No values
Stacks:
- Solidity
Bitgear
By using the Ox protocol, Bitgear helps to find the best prices across exchanges and combines them into one trade.
Features
- 0x protocol integration
- all DEXs trading
- limit orders
- multiple wallets support
Stacks:
- React
- Web3
- 0x protocol
- Solidity
Minto
Mine Bitcoin by staking BTCMT tokens. We’ve made smart contracts and crosschain integration between blockchains that helps to make mining easier than getting a BTC wallet.
Features
- HECO blockchain integration
- staking
- mining tokenization
Stacks:
- React
- Web3
- Python
- Solidity
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.
Features
- Staking
- Auction
- H2T token swap
- Uniswap auto-buy
- Dashboard
Stacks:
- Solidity
