State Variables ​

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.

solidity
bytes32 internal constant GOVERNANCE_SLOT = 0xb53127684a568b3173ae13b9f8a6016e243e63b6e8ee1178d6a717850b5d6103;

EXCHANGE_PRICES_PRECISION ​

solidity
uint256 internal constant EXCHANGE_PRICES_PRECISION = 1e12;

NATIVE_TOKEN_ADDRESS ​

address that is mapped to the chain native token

solidity
address internal constant NATIVE_TOKEN_ADDRESS = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE;

NATIVE_TOKEN_DECIMALS ​

decimals for native token

solidity
uint8 internal constant NATIVE_TOKEN_DECIMALS = 18;

MIN_TOKEN_DECIMALS ​

Minimum token decimals for any token that can be listed at Liquidity (inclusive)

solidity
uint8 internal constant MIN_TOKEN_DECIMALS = 6;

MAX_TOKEN_DECIMALS ​

Maximum token decimals for any token that can be listed at Liquidity (inclusive)

solidity
uint8 internal constant MAX_TOKEN_DECIMALS = 18;

SECONDS_PER_YEAR ​

Ignoring leap years

solidity
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.

solidity
uint256 internal constant MAX_TOKEN_AMOUNT_CAP = uint256(uint128(type(int128).max));

MAX_INPUT_AMOUNT_EXCESS ​

limit for triggering a revert if sent along excess input amount diff is bigger than this percentage (in 1e2)

solidity
uint256 internal constant MAX_INPUT_AMOUNT_EXCESS = 100;

SKIP_TRANSFERS ​

if this bytes32 is set in the calldata, then token transfers are skipped as long as Liquidity layer is on the winning side.

solidity
bytes32 internal constant SKIP_TRANSFERS = keccak256(bytes("SKIP_TRANSFERS"));

FORCE_STORAGE_WRITE_AFTER_TIME ​

time after which a write to storage of exchangePricesAndConfig will happen always.

solidity
uint256 internal constant FORCE_STORAGE_WRITE_AFTER_TIME = 1 days;

SMALL_COEFFICIENT_SIZE ​

constants used for BigMath conversion from and to storage

solidity
uint256 internal constant SMALL_COEFFICIENT_SIZE = 10;

DEFAULT_COEFFICIENT_SIZE ​

solidity
uint256 internal constant DEFAULT_COEFFICIENT_SIZE = 56;

DEFAULT_EXPONENT_SIZE ​

solidity
uint256 internal constant DEFAULT_EXPONENT_SIZE = 8;

DEFAULT_EXPONENT_MASK ​

solidity
uint256 internal constant DEFAULT_EXPONENT_MASK = 0xFF;

FOUR_DECIMALS ​

constants to increase readability for using bit masks

solidity
uint256 internal constant FOUR_DECIMALS = 1e4;

TWELVE_DECIMALS ​

solidity
uint256 internal constant TWELVE_DECIMALS = 1e12;

X8 ​

solidity
uint256 internal constant X8 = 0xff;

X14 ​

solidity
uint256 internal constant X14 = 0x3fff;

X15 ​

solidity
uint256 internal constant X15 = 0x7fff;

X16 ​

solidity
uint256 internal constant X16 = 0xffff;

X18 ​

solidity
uint256 internal constant X18 = 0x3ffff;

X24 ​

solidity
uint256 internal constant X24 = 0xffffff;

X33 ​

solidity
uint256 internal constant X33 = 0x1ffffffff;

X64 ​

solidity
uint256 internal constant X64 = 0xffffffffffffffff;
