Smart Contracts

All smart contracts will be displayed here.

Cygnus is being deployed first on Polygon PoS, followed by ZKEVM and other EVMs, and finally Starknet. Every single contract we deploy is open source and can be found on our Github. Furthermore all contracts are verified on block explorers and we do not make use of proxies.

Schema

Protocol Overview

1. Core Contracts (Lending Pools) are deployed by the Hangar18 contract - Factory.

2. Users interact with the lending pools through a Periphery Router - Though users could create their own to interact with the protocol too.

3. When users lend or borrow, the core contracts pass the information to the Pillars Of Creation contract - CYG Rewarder.

4. Since each lending pool consists of USDC and LP Deposits, each side has its own strategy (USDC strategy and LP strategy). These strategies earn rewards from the DEX and from the USDC strategy.

5. Most of the harvest is reinvested in their respective pool, and the other part is sent to the X1 vault (CYG Staking).

6. The contracts mint reserves in the form of CygUSD, according to the reserve rate (default 10%). 100% of the reserves are then redeemed for USDC and sent to the vault.

7. Users can stake CYG in the vault to claim back reserves and to earn rewards from all pools in Cygnus.

The whole protocol has no fees and users are free to deposit/borrow/withdraw whenever they want, without paying anything but the network gas.

The DAO and protocol however does earn profits, but only via liquidations! Each pool has a unique liquidation fee (named liquidationFee in the collateral contracts) and when liquidations occur the protocol seizes this liquidation fee from the borrower, receiving all profits in the form of LPs. The default set is 1% and is an upgradable parameter within 0%-10%.

CygnusDAO earns profits ONLY through liquidations, in the form of liquidity tokens (BPT's, LP's, etc.). This means 100% of the protocol reserves are in the form of liquidity tokens and are constantly earning from trading fees/liquidity mining rewards.
