Debt Tokens
- Stable debt tokens, representing a debt to the protocol with a stable interest rate
- Variable debt tokens, representing a debt to the protocol with a variable interest rate
Although debt tokens are modelled on the ERC20/EIP20 standard, they are non-transferrable. Therefore they do not implement any of the standard ERC20/EIP20 functions relating to
transfer() and allowance().balanceOf() will always return the most up to date accumulated debt of the user.totalSupply() will always return the most up to date total debt accrued by all protocol users for that specific type (stable vs variable) of debt token.function UNDERLYING_ASSET_ADDRESS()Returns the underlying asset of the debt token.
function POOL()function approveDelegation(address delegatee, uint256 amount)Sets the
amount of allowance for delegatee to borrow of a particular debt token.Parameter Name | Type | Description |
delegatee | address | the user receiving the allowance |
amount | uint256 | the allowance amounts given to user |
function borrowAllowance(address fromUser, address toUser)Returns the borrow allowance
toUser has been given by fromUser. Parameter Name | Type | Description |
fromUser | address | the user giving allowance |
toUser | address | the user receiving the allowance |
Returns the current allowance of
toUser for a particular debt token.function getSupplyData()Returns the supply / deposit data for the debt token.
Type | Description |
uint256 | principal supply |
uint256 | total supply |
uint256 | average borrow rate |
uint40 | timestamp for last supply update |
function getTotalSupplyAndAvgRate()Returns the total supply and average stable rate of the token.
Type | Description |
uint256 | total supply |
uint256 | average stable rate |
function principalBalanceOf(address user)Returns the principal debt balance of the
user.function getUserLastUpdated(address user)Returns the timestamp of the last action taken by
user as uint40.function getAverageStableRate()Returns the average stable rate across all the stable rate debt in the protocol as
uint256.function getUserStableRate(address user)Returns the stable rate of
user as uint256.function scaledBalanceOf(address user)Returns the principal debt balance of
user.function scaledTotalSupply()Returns the scaled total supply of the variable debt token.
This represents
.
function getScaledUserBalanceAndSupply(address user)Returns the principal balance of the
user and principal total supply.Type | Description |
uint256 | principal balance of user |
uint256 | principal total supply |
