High-performance trading bot powered by analytics.

Prerequisities

• A processor & some electricity
• Preferably Linux distro
• PostgreSQL
• Faith.
• & an RPC provider

Features

• Check current consensus leader's location to make decisions
• A Postgre database hooked into Pump.fun and Pump.fun AMM
• Integrated SWQoS Services:

• Durable nonce when using SWQoS
• Choose between gRPC or Websocket
• Plug-n-play trading strategies:

• Configurable trading filters (see .env)

Setup

Download the repository

$ git clone https://github.com/FLOCK4H/Mew-X
$ cd Mew-X

Create databases

$ psql -U yourpostgreuser
$ > CREATE DATABASE vacation;
$ > CREATE DATABASE goldmine;

If you can't psql -U yourpostgreuser you can follow the example below:

$ sudo nano /etc/postgresql/16/main/pg_hba.conf
Modify like this, change peer to trust:
local   all             postgres                                trust
TYPE  DATABASE        USER            ADDRESS                 METHOD
"local" is for Unix domain socket connections only
local   all             all                                     trust
IPv4 local connections:
host    all             all             127.0.0.1/32            trust
IPv6 local connections:
host    all             all             ::1/128                 scram-sha-256
Allow replication connections from localhost, by a user with the
replication privilege.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            scram-sha-256
host    replication     all             ::1/128                 scram-sha-256

Set path to your database in the .env file:

DB_URL = "postgres://<user>:<password>@<host>:<port>" # need a valid postgre path
example
DB_URL = "postgres://postgres@127.0.0.1:5432" # need a valid postgre path

Tables will be created on launch.

Configure the .env file

All variables should be self-explanatory, if something isn't clear or you're stuck and need help, please visit Telegram or Discord groups.

Build & run the project

$ cargo run

First, Mew will fetch locations of nodes participating in the cluster. Indexing of (at the time of writing) 6000+ validators takes around 1.5 hour, we do that to speed up the location checks when trading.

Indexing HrLAr7y9k8qYd14uF5KdTz5z9p9BvZuf1o6cKY255wtD @ 80.240.31.38 -> ("Frankfurt", "Germany")
Indexing B7PbdWDgqc5h5rbTyi5Yyz2e1DJZEMoM3uXoqobk35n9 @ 202.8.11.203 -> ("Singapore", "Singapore")
Indexing Apt9PHrFBt1sji788VzwBYpYensM43eA6qLVybqZrKak @ 65.21.90.166 -> ("Helsinki", "Finland")

(Optional) Development

There are lots of tests in sol.rs of sol_hook, to save you some trouble here is the command:

$ cargo test mew::solhook::sol::tests::testpump_buy -- --exact --no-capture
