# Tokenlon MMSK
-Market maker server kit, for tokenlon's MM(Market Maker).
+Market Maker Service Kit.
-See [docs](https://docs.token.im/tokenlon-mmsk/)
-
-## Setup
-
-Require Node.JS v12 as runtime.
-
-Program setup,
-- Create a wallet as order signer, and save it as keystore or private key
-- Deploy market maker proxy contract on ethereum
- - with several permissions setting, such as token allowance, withdrawal account
- - deposit token asset to contract
-- Implement a market maker backend http server
- - see Quoter interface, mostly quote with (buy, sell, amount) returning a price number
-- Modify the options in `app/mmConfig.js`, including,
- - EXCHANGE_URL, point to tokenlon exchange server
- - PROVIDER_URL, point to ethereum node, like your infura endpoint
- - PERMIT_TYPE, approve tokens to `RFQv2` contract directly or approve tokens to `AllowanceTarget` contract.
- - WALLET_ADDRESS, as your signer wallet address
- - WALLET_PRIVATE_KEY, private key of above wallet, or use WALLET_KEYSTORE
- - WALLET_TYPE, a market maker's wallet smart contract.
- - types.WalletType.MMP_VERSION_4 (compatible with PMM protocol, see [example contract](https://gist.github.com/NIC619/a3db1a743175bf592f2db983f17680dd#file-mmpv4-sol-L1236))
- - types.WalletType.MMP_VERSION_5
- - types.WalletType.ERC1271
- - types.WalletType.EOA
- - SIGNING_URL, If you wanna sign orders in your own service instead of the mmsk,
- please set the SIGNING_URL to your service endpoint. the mmsk would post every unsigned PMM/RFQV1/RFQV2 orders to your service. Remember to set the WALLET_ADDRESS as well. Example PMMV5/RFQV1/RFQV2 requests are shown below:
-

+# Tokenlon Market Maker Service Kit
+
+## Introduction
+
+**Tokenlon-MMSK** is a tool to start nodejs http service for market making. The service is deployed on the market maker side. It is an intermediate proxy that connects the Tokenlon Server and the market maker service. MMSK stands for **Market Maker Service Kit**, which is used to reduce the cost of communication at both ends.

+# Installation
+Download the latest [release here](https://github.com/consenlabs/tokenlon-mmsk/releases).
+
+To be sure that the file **hasn’t** been tampered with, we suggest the market maker checks the downloaded zip file’s sha256 checksum, for example via: `shasum -a 256 /path/to/file`
+
+After the check and un-zip is completed, enter the tokenlon-mmsk root directory, and execute:
+
+`yarn` or `npm install`

+# Interfaces for Market-Makers
+
+The market maker needs to implement following 5 **Tokenlon-MMSK** interfaces:
+
+1. The pairs interface asks market maker for authorized trading currency pairs
+2. The indicativePrice interface asks market maker to provide a reference price for a specific trading currency pair
+3. The price interface asks the market maker quoting prices for a specific trading amount
+4. The deal interface: Once the quote confirmed by the users, the Tokenlon Server will push an order to the MMSK, and MMSK then notifies the market maker via the deal interface
+5. The exception interface: Once the order has some exception situation, the Tokenlon Server will push an exception order to the MMSK, and MMSK then notifies the market maker via the exception interface

+
+1. The market maker needs to prepare a wallet for signature, the **marketMakerSigner**
+2. Contact Tokenlon and provide the **signing EOA** wallet address and your existing market making wallet contract to Tokenlon. if you don't have one, Tokenlon will deploy a **MarketMakerProxyContract** for you.
+3. Contact Tokenlon for environment parameters such as `EXCHANGE_URL`
+4. Deposit tokens to your **market making contract wallet**
