Parameters
Name | Type | Description |
---|---|---|
user | address | protocol that triggered this operation (e.g. via an fToken or via Vault protocol) |
token | address | token address for which this operation was executed |
supplyAmount | int256 | supply amount for the operation. if >0 then a deposit happened, if <0 then a withdrawal happened. if 0 then nothing. |
borrowAmount | int256 | borrow amount for the operation. if >0 then a borrow happened, if <0 then a payback happened. if 0 then nothing. |
withdrawTo | address | address that funds where withdrawn to (if supplyAmount <0) |
borrowTo | address | address that funds where borrowed to (if borrowAmount >0) |
totalAmounts | uint256 | updated total amounts, stacked uint256 as written to storage: First 64 bits => 0- 63 => total supply with interest in raw (totalSupply = totalSupplyRaw * supplyExchangePrice); BigMath: 56 |
exchangePricesAndConfig | uint256 | updated exchange prices and configs storage slot. Contains updated supply & borrow exchange price: First 16 bits => 0- 15 => borrow rate (in 1e2: 100% = 10_000; 1% = 100 -> max value 65535) Next 14 bits => 16- 29 => fee on interest from borrowers to lenders (in 1e2: 100% = 10_000; 1% = 100 -> max value 16_383). configurable. Next 14 bits => 30- 43 => last stored utilization (in 1e2: 100% = 10_000; 1% = 100 -> max value 16_383) Next 14 bits => 44- 57 => update on storage threshold (in 1e2: 100% = 10_000; 1% = 100 -> max value 16_383). configurable. Next 33 bits => 58- 90 => last update timestamp (enough until 16 March 2242 -> max value 8589934591) Next 64 bits => 91-154 => supply exchange price (1e12 -> max value 18_446_744,073709551615) Next 64 bits => 155-218 => borrow exchange price (1e12 -> max value 18_446_744,073709551615) Next 1 bit => 219-219 => if 0 then ratio is supplyInterestFree / supplyWithInterest else ratio is supplyWithInterest / supplyInterestFree Next 14 bits => 220-233 => supplyRatio: supplyInterestFree / supplyWithInterest (in 1e2: 100% = 10_000; 1% = 100 -> max value 16_383) Next 1 bit => 234-234 => if 0 then ratio is borrowInterestFree / borrowWithInterest else ratio is borrowWithInterest / borrowInterestFree Next 14 bits => 235-248 => borrowRatio: borrowInterestFree / borrowWithInterest (in 1e2: 100% = 10_000; 1% = 100 -> max value 16_383) |
