  • address toToken - output token

  • uint256 amount - exchange amount

  • string targetName - connector name

  • bytes data - calldata for the exchange

Commission calculation

  • For each position opening, the commission is calculated based on the leveraged transaction amount and the commission set on the contract, the commission can only be changed by the configurator contract.

Router

  • Position opening and creation of proxy accounts for users

  • Accounts are created by cloning a proxy contract when a position is opened and the user has no account

  • It stores the data of all user accounts and positions.
