VELA EXCHANGE

A complete breakdown of our exchange functionality and all contract addresses, functionality and more can be found in our Gitbook

Basic Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts. If you are not familiar with hardhat, you can refer it from the link below. https://hardhat.org/tutorial

Try running some of the following tasks:

npx hardhat node
npx hardhat clean
npx hardhat compile
npx hardhat test
npx hardhat coverage
npx hardhat run --network network_name scripts/perpetual/network_name/deployFinalScript.js (network name can be arbitrum or arbitrum goerli)
npx hardhat help

For formatting the code, you can run it

yarn solidity-prettier

A complete list of scripts can be found in the scripts folder:

/scripts/arbitrum for Arbitrum Mainnet

/scripts/arbitrum_goerli for Arbitrum Goerli Testnet

Deployed Contracts

All contracts deployed to Arbitrum Mainnet are detailed at in our Mainnet Contract Addresses

All contracts deployed to Arbitrum Goerli are detailed at in our Testnet Contract Addresses

Contract Folders

Access

The access contracts hold constants for configuration used throughout Vela Exchange as well as the Governable contract which sets up ownership and allows the ability to set admin roles and call admin functions. Detailed explanations and code can be found in the Access Section.

Core

The core contracts hold - you guessed it - the core functionality of Vela Exchange. Our vault contract gives traders the ability to deposit, withdraw, open and close positions, and more. Liquidity providers can call functions to stake and unstake stable tokens, thereby minting VLP. Various settings contracts control the settings and configurations for the vault, pricing feeds for assets, and contracts allowing for the opening and triggering of orders. To see code examples and more detail please visit the Core Section.

Oracle

Vela Exchange asset pricing is based on our own FastPriceFeed, which we operate internally. Asset prices are pulled from the latest data sources and published on chain in real time. You can view our Oracle Section for more information.

Staking

In addition to staking in our vault to provide liquidity, we provide various staking options for the VELA token, eVELA and more to earn more rewards and get reduced trading fees. You can see the details on our TokenFarm contract in the Staking Section.

Tokens

The Vela token ecosystem consists of the VELA token as well as our VLP token for liquidity providers, eVELA for vesting VELA tokens over time, and vUSD which is the collateral token for trading. You can see all of our contract info on the various tokens in our Tokens Section.

Vault

this is main contract for managing all stakes, unstakes, deposits, withdraws, positions, and orders,

setVaultSettings

OnlyOwner Function

this is intialize function for combining relative contracts to Vault This is called only one time.

vault.setVaultSettings(
        IPriceManager _priceManager,
        ISettingsManager _settingsManager,
        IPositionVault _positionVault
    )

Example Input

('0x2c4478Dd91341Cb50521F2Af7174FB3C73A7DbEC', '0xce12b20F44E8fD27E4cd67eBc5c4F871400f84e7', '0x1dd07152b883c1d0A8490A35121A2e559dFE0702')

Example Output


deposit

This is a function to deposit USDC for getting vUSD. Users can open and close positions with vUSD for getting profits via leverage. So users need to deposit USDC at first time.

vault.deposit (
        address _account,
        address _token,
        uint256 _amount
    ) 

Example Input for depositing 100 USDC(USDC decimals is 6),

('0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266', '0x93F2394ceA60fa9E2E9AC215cd8ba04c30ed103b', 
'100000000')

Example Output


withdraw

This is a function to withdraw USDC from vUSD. So after using this platform, if you want to withdraw your profits, then you can call this function.

vault.withdraw(
        address _token,
        address _account,
        uint256 _amount
    ) 

Example Input for withdawing 100 vUSD(vUSD decimals is 30),

('0x93F2394ceA60fa9E2E9AC215cd8ba04c30ed103b',  '0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266', 
'10000000000000000000000000000000')

Example Output


stake

This is a function to stake USDC for getting VLP. By staking USDC, you will receive VLP. Every time fees are generated, vlp price will be increased. VLP holders will receive rewards from our platform fees.

vault.stake(
        address _account,
        address _token,
        uint256 _amount
    )

Example Input for staking 100 USDC(USDC decimals is 6),

Example Output


unstake

This is a function to unstake VLP for getting rewards. According to vlp amount and USDC amount(include platform fees), vlp price will be changed. So, by unstaking VLP at higher price than staking price, user will get the reward. There is cooldownduration for unstaking VLP. So users need to wait for cooldownduration before unstaking

vault.unstake(
        address _tokenOut,
        uint256 _vlpAmount,
        address _receiver
    )

        bool _isLong,
        uint256 _posId,
        uint256 _collateralDelta,
        uint256 _sizeDelta
    )

Example Input If you wanna add collateral 10, position size 100, then

        bool _isLong,
        uint256 _posId,
        uint256[] memory _params
    )

    _params[0] -> the collateral amount what you are going to add trailing stop for
    _params[1] -> the position size what you are going to add trailing stop for
    _params[2] -> trailing step type, so trailing step type = 0 means 'by price', type = 1 means 'by percent'
    _params[3] -> step size

Example Input if you wanna add trailing stop by price change(so you want to take trail stop order when the last price exceeds 1$ change)
