listen

Listen to new large transactions on Raydium V4

Swap using Pump.fun, Jupiter V6 API or directly with Raydium (crucial for new listings)

Monitor prices real-time, multiple subscription ways and providers (PubSub, webhooks..)

This tool has accidentally evolved to something of a sort of a Solana swiss-knife, has a bunch of stuff useful when trading shitcoins on Raydium and Pump.fun and some utilities like generating a custom wallet pubkey, mine is fuckTY... :D

There are some methods for sniping both platforms, 'sweeping' all of the bought tokens (selling hundreds of bought tokens), closing all of the associated token accounts (if you snipe ~500 tokens you can close those accounts later and retrieve like 1 sol), check out the functionalities in the outline below

$ listen
Usage: listen [OPTIONS] <COMMAND>

Commands:
  close-token-accounts
  pump-service
  grab-metadata
  sell-pump
  bump-pump
  sweep-pump
  snipe-pump
  buy-pump-token
  generate-custom-address
  ata
  spl-stream
  monitor-mempool
  seller-service
  checker-service
  checks
  blockhash
  listen-for-sol-pooled
  buyer-service
  track-position
  top-holders
  monitor-leaders
  monitor-slots
  price

  tx
  listen
  listen-for-burn
  listener-service
  snipe
  wallet
  parse-pool
  swap
  help                 Print this message or the help of the given subcommand(s)

Options:
  -u, --url <URL>                 [default: https://api.mainnet-beta.solana.com]
  -w, --ws-url <WS_URL>           [default: wss://api.mainnet-beta.solana.com]
  -k, --keypair-path <KEYPAIR_PATH>
      --tokio-console
  -h, --help                      Print help
  -V, --version                   Print version

Be careful as the default usage was on mainnet with small txs, be sure to set the URLs and signer keypair to testnet, read the code too so that you don't mess anything up

Requirements

  1. Install Rust
  2. Install protoc, build-essential, pkg-config, libssl-dev
  3. Copy over .env.example into .env, plug your RPCs (otherwise uses solana default public RPCs)
  4. Copy over auth.json - JITO authentication keypair and fund.json - the keypair with some SOL to fund the endeavour
  5. Enable Rust Nightly and cargo build --release
  6. Run the ./run-systemd-services.sh to run the microservices

Usage

Listening on new swaps

Requires env var of RPC_URL with some quota, set the size of buffer for new transactions and the worker count that process incoming transactions

Listening is over wss://api.mainnet-beta.solana.com/, fetching transactions uses the url set in RPC_URL

cargo run -- listen \
  --worker-count [COUNT] \
  --buffer-size [SIZE]

Should yield output as

Metrics server running on 3030

Connecting to logs for 675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8

Connecting to blocks through [RPC_URL]
Latest blockhash: BS8s86pQf45V9skwmzWz4GsYyZs6A8gsNWy4i9piV786
Signer: DmFqB5LdQspumdvtHRi4PHKTZENHMw2xRMmSXP6aSkfj

https://solana.fm/tx/3Gvmx...: 10.730849095 SOL
https://solana.fm/tx/4aGoJ...: 77.293938152 SOL
https://solana.fm/tx/j7TD...: 77.681362228 SOL

Automatically, it will send metrics to localhost:3030/metrics; to see the transactions received and processed in Prometheus, run

prometheus --config=prometheus.yml

This will start a server on localhost:3030/metrics that contains metrics (transactions_received and transactions_processed)

In Grafana it looks like this: image

Swapping

The account used to sign the transaction is by default the ~/.config/solana/id.json, but it is possible to specify the path using --keypair-path [PATH], the account has to be generated or imported using solana-keygen executable that ships with remaining the Solana SDK

Slippage can also be adjusted using --slippage [BPS], e.g. --slippage 50 for 0.5% slippage, default is 50, dynamic slippage and retries is in the prod roadmap

cargo run -- swap \
  --input-mint sol \
  --output-mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v \
  --amount 10000000

Amount is in lamports (or SPL-Token decimals), leave blank to automatically swap the entire balance of the input mint

There is an optional parameter -y or --yes which skips the confirmation on the user side

Swap profiling

There is a utility for profiling a single swap using DTrace and stackcollapse.pl (Repository), replace your home directory (mine is /Users/piotrostr) to point to the right id.json keypair

./hack/profile-swap.sh

The stackcollapse.pl can be installed through

gh repo clone brendangregg/FlameGraph && \
  sudo cp FlameGraph/stackcollapse.pl /usr/local/bin && \
  sudo cp FlameGraph/flamegraph.pl /usr/local/bin
