listen started sa Solana Swiss-Knife toolkit for algorithmic trading, its mission has become the go-to framework for AI crosschain portfolio management agents

It powers the Listen App, check it out to see what listen framework is capable of

Features

• 🔍 Real-time transaction monitoring
• 💱 Multi-DEX swap execution (Pump.fun, Jupiter V6 API or Raydium)
• 🚀 Blazingly fast transactions thanks to Jito MEV bundles
• 📊 Price tracking and metrics
• 🧰 Token management utilities
• 📈 Performance monitoring with Prometheus integration

And more!

It works plug'n'play with $arc rig framework framework allowing AI Agents interact with the Solana blockchain, see example: src/agent.rs and the output image.

Some more docs on the agentic stuff: rig-onchain-kit

For complete rundown of features, check out the CLI output of cargo run or the documentation.

Quickstart

To play around with listen-rs, you can use the UI

Fill in the .env.example and ./dashboard/.env.example, copy over to .env and ./dashboard/.env.example, then

docker compose up

You can then access the dashboard over http://localhost:4173

[!WARNING]

listen-rs is undergoing rapid iterations, some things might not work and there could be breaking changes

Requirements

• System Dependencies

- Rust (with nightly toolchain) - protoc - build-essential - pkg-config - libssl-dev

• Configuration

- Copy .env.example to .env - Set up auth.json for JITO authentication (optional, gRPC HTTP/2.0 searcher client) - Populate fund.json

Both keypairs are in solana-keygen format, array of 64 bytes, 32 bytes private key and 32 bytes public key.

Quick Start

# Install dependencies
sudo apt install protoc build-essential pkg-config libssl-dev
Build
cargo build --release
Run services
./run-systemd-services.sh

Usage Examples

Transaction Monitoring

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

Token Swapping

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

[!WARNING]

Default configuration is set for mainnet with small transactions. Ensure proper configuration for testnet usage and carefully review code before execution.

Metrics and Monitoring

Listen includes built-in metrics exposed at localhost:3030/metrics. To visualize:

• Start Prometheus:

prometheus --config=prometheus.yml

• Access metrics at localhost:3030/metrics

Grafana should show something like this

Advanced Usage

Swap Profiling

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

Profile swap performance using DTrace to produce a flamegraph:

./hack/profile-swap.sh
