GOVERNANCE_SLOT
Storage slot with the admin of the contract. Logic from "proxy.sol". This is the keccak-256 hash of "eip1967.proxy.admin" subtracted by 1, and is validated in the constructor.
bytes32 internal constant GOVERNANCE_SLOT = 0xb53127684a568b3173ae13b9f8a6016e243e63b6e8ee1178d6a717850b5d6103;
EXCHANGE_PRICES_PRECISION
uint256 internal constant EXCHANGE_PRICES_PRECISION = 1e12;
NATIVE_TOKEN_ADDRESS
address that is mapped to the chain native token
address internal constant NATIVE_TOKEN_ADDRESS = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE;
NATIVE_AMOUNT_EXCESS_LIMIT
limit for triggering a revert if sent along excess msg.value
is bigger than this amount
uint256 internal constant NATIVE_AMOUNT_EXCESS_LIMIT = 1e9;
SECONDS_PER_YEAR
Ignoring leap years
uint256 internal constant SECONDS_PER_YEAR = 365 days;
MAX_TOKEN_AMOUNT_CAP
limit any total amount to be half of type(uint128).max (~3.4e38) at type(int128).max (~1.7e38) as safety measure for any potential overflows / unexpected outcomes. This is checked for total borrow / supply.
