Interface

dToken contract is fully compatible with ERC20 standard, other interfaces are descripted here.

Send Transactions

• mint(address _dst, uint _pie)

  mint certain amount of underlying to dst address

  • _dst: account who will get dToken.

  • _pie: underlying token amount.

• redeem(address _src, uint _wad)

  redeem certain amount of dToken from dst address

  • _src: account whose dToken will burn from.

  • _wad: dToken amount to burn.

• redeemUnderlying(address _src, uint _pie)

  redeem certain amount of underlying from dst address

  • _src: account whose dToken will burn from.

  • _pie: underlying token amount to withdraw.
