Tangle AVS: Cross-Chain Quickstart Guide

The following is a guide outlining the steps to set up and utilize Tangle AVS (Actively Validated Services), allowing you to run a Tangle Validator on EigenLayer's network. If you do not have a Tangle node set up yet, please review the How to run a Tangle node setup guide here.

This guide will help you get started with deploying the AVS and enabling cross-chain functionalities across multiple blockchain protocols, specifically EigenLayer.

Here is how our final configuration will look at the end of this guide:

• Tangle AVS operates as an EigenLayer-compatible validator and supports cross-chain slashing.
• EigenLayer integration allows validators to re-stake and enhance security while also participating in Tangle’s validator ecosystem.
• Symbiotic will be integrated in the future, allowing cross-chain collaboration.
• Message dispatching between networks using bridges, Hyperlane, or Sygma.
• Optional AVS and Blueprint Development tools in Rust for developers who want to create their own AVSs or Blueprints to interact with the Tangle and/or EigenLayer network(s).

Docker usage

---- INCLUDES PLACEHOLDER TEXT ----

The quickest way to set up the Tangle AVS with cross-chain functionalities is to use our provided scripts.

Prerequisites

Before starting, ensure that the following is configured:

• Access to a running EigenLayer node and correct port exposure for cross-network communication.
• Set up necessary configurations for bridges, Hyperlane, or Sygma for message dispatching across networks.

Usage

To start the Tangle AVS, run:

cd avs-setup
./placeholder_setup_script.sh

Cross-Chain Functionality Configuration

The Tangle AVS requires the registration of an Operator through both EigenLayer and Tangle - you must have the configurations for both Operators accessible. For more information on cross-chain functionalities you can see our Cross-Chain Orchestration section.

EigenLayer Integration

Ensure that the Tangle Validator is registered within the EigenLayer AVS and that the node is actively listening for cross-chain messages. Set up cross-chain slashing to be enforced across both Tangle and EigenLayer by dispatching slashing messages via Hyperlane or another communication protocol.

Symbiotic Integration (Future)

[Placeholder] Symbiotic integration is under development. Once available, you will be able to configure cross-chain slashing and collaborative consensus mechanisms across both Tangle and Symbiotic.

Other Network Configurations

For non-Tangle networks, configure Hyperlane or Sygma to handle cross-chain message dispatching and validator state updates across networks.

Monitoring and Alerts

To monitor your Tangle AVS and its interactions across networks like EigenLayer, set up Prometheus and Grafana for real-time tracking of your validator’s performance and cross-chain activities.

cd monitoring
docker compose up -d

Navigate to http://localhost:3000 (opens in a new tab) to view real-time metrics such as:

Validator performance across EigenLayer and other networks. Cross-chain message dispatch status. Slashing events and validator health.

Next Steps

You’ve successfully set up and configured your Tangle AVS with cross-chain functionalities! You can now participate in EigenLayer’s re-staking mechanism while benefiting from Tangle’s cross-chain validator management.
