const (
	// MaxOrderSizeInBytes is the maximum number of bytes allowed for encoded
	// orders. It allows for MultiAssetProxy orders with roughly 45 total ERC20
	// assets or roughly 36 total ERC721 assets (combined between both maker and
	// taker; depends on the other fields of the order).
	MaxOrderSizeInBytes = 16000

	// MaxMessageSizeInBytes is the maximum size for messages sent through
	// GossipSub. It is the max order size plus some overhead for the message
	// format.
	MaxMessageSizeInBytes = MaxOrderSizeInBytes + messageOverhead
)

const MaxBlocksStoredInNonArchiveNode = 128

MaxBlocksStoredInNonArchiveNode is the max number of historical blocks for which a regular Klaytn node stores archive-level state. One cannot make `klay_call` requests specifying blocks earlier than 128 blocks ago on non-archive nodes.

Variables

var (
	// ErrMaxMessageSize is returned or emitted when a GossipSub message exceeds
	// the max size.
	ErrMaxMessageSize = fmt.Errorf("message exceeds maximum size of %d bytes", MaxMessageSizeInBytes)
	// ErrMaxOrderSize is returned or emitted when a signed order encoded as JSON
	// exceeds the max size.
	ErrMaxOrderSize = fmt.Errorf("order exceeds maximum size of %d bytes", MaxOrderSizeInBytes)

var ErrInternal = errors.New("internal error")

ErrInternal is used whenever we don't wish to expose internal errors to a client

var NullAddress = common.HexToAddress("0x0000000000000000000000000000000000000000")

NullAddress is an Klaytn address with all zeroes.

var NullBytes = common.FromHex("0x")

NullBytes is an empty byte array

var UnlimitedExpirationTime *big.Int

UnlimitedExpirationTime is the maximum value for uint256 (2^256-1), which means there is effectively no limit on the maximum expiration time for orders.
