Chain IDs

The following is a list of Zigzag Chain IDs. Note that there is no relation between this and Ethereum Chain IDs.

IDs < 1000 are mainnet contracts. IDs >= 1000 are testnet contracts.

Name	ID
zkSync Mainnet	1
zkSync Goerli	1002

Websocket vs REST

Our API is designed to be used as a Websocket API. The message structures and response methods are optimized for Websocket use. However, we understand in some cases a REST API is just more convenient, so a couple select methods in our API are available over HTTP POST.

The HTTP POST API uses the same endpoint as the websocket API. It is a single endpoint API where messages are passed in the exact same structure as the Websocket message. See Structure for how POST and Websocket messages should be structured.

The current list of operations available over HTTP POST are: submitorder3, requestquote, orderreceiptreq, refreshliquidity, dailyvolumereq and marketsreq.

Sending orders on zksync

The Zksync limit order system is pretty complicated, so we've simplified it down into an RFQ.

There's a requestquote operation you can use to get an all in price including gas fees charged for relaying. The smaller the amount, the further away from spot it's going to be because of the variable fee.

Using the price from the quote response, you can send a limit order with submitorder3. An order sent at the quote price will fill like a market order.

Structure

All messages the Zigzag Websocket API have the following structure

{ "op": "operation", "args": ["list", "of", "args"] }

Messages to the HTTP POST API have a similar structure. An example curl command is found below.

curl -X POST "https://zigzag-exchange.herokuapp.com/" --header "Content-Type: application/json" -d '{"op":"requestquote", "args": [1002, "ETH-USDT", "b", "0.232"]}'

Pings

The server sends a ping message every 30 seconds to assure the connection is alive. A pong response is expected in return.

Most websocket clients handle the ping message automatically, so no extra work should be required on your part.

Dead connections are auto closed.

Order Statuses

Shorthand	Status
c	canceled
o	open
e	expired
m	matched, but not committed to chain. price listed in args.
r	rejected. txhash and error listed in args
f	filled and committed. txhash listed in args.
b	broadcasted. txhash listed in args.
pf	partial fill. quantity and price listed in args.
pm	partial match.

Operations

Operation: login

Arguments: [chainId, userId]

Description: Associate userId with connection. Note that userId is a string, not an integer, even though zkSync represents account IDs as integers. This is to maintain compatibility with other chains that might use string fields (ETH addresses, ENS account names, etc) for account IDs.

{ "op": "login", "args": [1002, "27334"] }

---

Operation: submitorder3

Arguments: [chainId, market, zkOrder]

Description: Submit an order.

For zksync, zkOrder is the output of zksync.wallet.getOrder in the Javascript library.

An example of how to submit an order with Javascript in zksync can be found here in the submitorder function.

This operation is also available over HTTP POST and returns a userorderack message.
