| ## Configuration | ||
|
|
||
| Require Node.JS v12 or above 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 [interfaces](interfaces.md), 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 | ||
| - HTTP_SERVER_ENDPOINT, your backend http quoting server. See [interfaces](interfaces.md) | ||
| - CHAIN_ID, 1 for mainnet, 5 for testnet(Goerli) | ||
| - PERMIT_TYPE, approve tokens to `RFQv2` protocol contract directly or approve tokens to `AllowanceTarget` contract for PMMV5/RFQV1 protocols. | ||
| - WALLET_ADDRESS, as your signer wallet address | ||
| - WALLET_PRIVATE_KEY, private key of above wallet, or use WALLET_KEYSTORE | ||
| - WALLET_TYPE, a type of market making wallet contract. | ||
| - types.WalletType.MMP_VERSION_4 (see [example contract](https://gist.github.com/NIC619/a3db1a743175bf592f2db983f17680dd#file-mmpv4-sol-L1236)) | ||
| - types.WalletType.ERC1271_EIP712: your market making contract could verify standard EIP712 signatures. | ||
| - types.WalletType.ERC1271_EIP712_EIP191: your market making contract could verify signatures correspond to the digest of EIP712 struct hash with a EIP191 prefix. | ||
| - 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 PMMV5/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` |
