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 GanacheEndpoint = "http://localhost:9545"

GanacheEndpoint specifies the Ganache test Ethereum node JSON RPC endpoint used in tests

const GethFilterUnknownBlock = "unknown block"

const MaxBlocksStoredInNonArchiveNode = 128

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

const ParityFilterUnknownBlock = "One of the blocks specified in filter (fromBlock, toBlock or blockHash) cannot be found"

const TestChainID = 1337

TestChainID is the test (Ganache) chainId used for testing

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

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

	GanacheAccount1: ganacheAccount1PrivateKey,
	GanacheAccount2: ganacheAccount2PrivateKey,

var TestMaxContentLength = 1024 * 512

TestMaxContentLength is the max Ethereum RPC Content-Length used in tests

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.
