Mango Markets Market Maker

Setup

To run the market maker you will need:

A Solana account with some SOL deposited to cover transaction fees
A Mango Account with some collateral deposited and a name (tip: use the UI)
Your wallet keypair saved as a JSON file
node and yarn

mkdir blockworks-foundation
cd blockworks-foundation
git clone https://github.com/blockworks-foundation/market-maker-ts.git
cd market-maker-ts
yarn install

## Open .env file and set env vars like this example ##
export KEYPAIR=~/.config/solana/id.json
export ENDPOINT_URL="https://mango.rpcpool.com/946ef7337da3f5b8d3e4a34e7f88"
export PARAMS=default.json

## Set mangoAccountName in params file to reflect the name of your MangoAccount

Run via terminal

. run.sh

Run via systemd

If you're running the market maker on a server, you might want to run it via systemd to have auto restarts

chmod 755 run.sh
cd /etc/systemd/system
sudo nano mm.service

## Set the systemd service file like this and replace the *** lines with your own
***ExecStart=/home/dd/blockworks-foundation/market-maker-ts/run.sh
***WorkingDirectory=/home/dd/blockworks-foundation/market-maker-ts/
Restart=always
RuntimeMaxSec=1800
RestartSec=5s
LimitNOFILE=4096
IgnoreSIGPIPE=false
KillMode=control-group
***User=dd

sudo systemctl daemon-reload
sudo systemctl start mm.service

You can watch the log output with:

journalctl -f -u mm.service

And stop the mm:

sudo systemctl stop mm.service
