Change fees

There are two settable fees in the Materia protocol:

• Swap fee is the fee that a trader pays per hop (a swap can only make one or two hops), and the default value is 30 basis points (0.3%)
• Materia fee is the part of swap fee that goes to the Materia DFO (the receiver is feeTo), the default value is 1/6.

Code example

This example changes the swap fee and the Materia fee for the pair WUSD-DAI.

function callOneTime(address) public {
  IMVDProxy dfoProxy = IMVDProxy(msg.sender);
  address daiToken = <daiAddress>;
  uint materiaFee = <materiaFee>;
  uint swapFee = <swapFee>;

  materiaOrchestrator.setFees(
    tokenDai,
    materiaFee,
    swapFee,
  ); 
}
Copy

Change default fees

It’s also possible to set the default swap fee and Materia fee i.e. the fees that are automatically set when the Materia Factory deploys a new pair.

Code example

function callOneTime(address) public {
  IMVDProxy dfoProxy = IMVDProxy(msg.sender);

  materiaOrchestrator.setDefaultFees(
    5, //Materia fee
    3, //Swap fee
  ); 
}
