DEX

The DEX component of Nautilus is built as a fork of UniswapV2. The fee structure and distribution mechanism will be fully implemented upon mainnet launch.

DEX Aggregator

The Nautilus Aggregator

We have implemented a fork of the Yak Aggregator (YakSwap) to serve as our aggregation layer. The integration is currently pending on testnet.

This onchain aggregator is designed to tap into liquidity pools across multiple DEXes in the Sonic ecosystem, helping drive trading volume and enhance overall market efficiency. (DEX Aggregators also play a crucial role in driving demand and liquidity fees to previously underutilized pools.)

Interfaces

Core View Functions

function getPrice(address _tokenAddress) public view returns (uint256);

function getPoolInfo(address _tokenAddress) external view override
  returns (
    bool _activated,
    uint256 _volume,
    address _creator,
    address _baseTokenAddress,
    uint256 _baseTokenReserves,
    uint256 _tokenReserves
  );

Trade Estimation

function estimateBuy(
    address _tokenAddress,
    uint256 _baseAmount
  ) public view returns (
    uint256 _tokenAmount,
    uint256 _fee,
    uint256 _usedBaseAmount
  );

function estimateSell(
    address _tokenAddress,
    uint256 _tokenAmount
  ) public view returns (uint256 _baseAmount, uint256 _fee);

Trade Methods

function buy(
    address _tokenAddress,
    uint256 _baseTokenAmount,
    uint256 _minTokenAmount
  ) external;
function buyWithETH(address _tokenAddress, uint256 _minTokenAmount) external payable;

function sell(
    address _tokenAddress,
    uint256 _tokenAmount,
    uint256 _minBaseTokenAmount,
    bool _isOutputETH
  ) external returns (uint256 _baseTokenAfterFee);

Flashloan

The protocol implements a flashloan mechanism that utilizes memecoin liquidity pools as its foundation. This feature is designed to promote a circular economy within our ecosystem, creating additional utility for accumulated liquidity.

Token Contract for Memecoins

• The protocol's token implementation follows a fixed total supply of 1 billion tokens (standard for common memecoins).

• Initially, ownership will be held by the core contract to mint and burn tokens during bonding curve transactions. After migration, ownership will be permanently renounced (renounceOwnership()) by transferring control to the zero address (0x0000...), ensuring protocol safety.
