Rollup-as-a-Service Tangle Blueprints 🌐

Tangle Network Blueprints 🌐

A collection of blueprints for deploying and managing rollup chains as a service, enabling automated deployment and operation of Layer 2 and Layer 3 scaling solutions through the Tangle Network.

Available Blueprints

Arbitrum Orbit RaaS (Rollup-as-a-Service)

Deploy and manage Arbitrum Orbit chains through a standardized service interface. This blueprint provides comprehensive management of Orbit chain deployments with the following features:

Initial Deployment

• Automated Orbit chain deployment with customizable configurations
• Support for both ETH and ERC20 native tokens
• Configurable token bridge setup
• Custom fee token configuration
• Data availability committee settings

Chain Management Features

The blueprint provides several management jobs that can be triggered through the Tangle Network:

1. Validator Management

   • Add/remove chain validators
   • Enable/disable validator sets

2. Executor Management

   • Configure privileged executors
   • Manage executor permissions

3. Fee Management

   • Configure fee recipients
   • Set fee distribution weights

4. Fast Withdrawals

   • Configure withdrawal confirmers
   • Enable/disable fast withdrawal functionality

Prerequisites

• Rust
• Node.js (v16 or later)
• Foundry
• Tangle CLI

Environment Setup

Required environment variables:

PARENT_CHAIN_RPC=           # Parent chain RPC endpoint
UPGRADE_EXECUTOR_ADDRESS=   # Address of the upgrade executor
OWNER_ADDRESS=             # Owner address for management operations
OWNER_PRIVATE_KEY=         # Private key for signing transactions

Architecture

Smart Contracts

The blueprint includes smart contracts for:

• Service registration and management
• Configuration storage and validation
• Access control and permissions

Service Implementation

Built with Rust and the Tangle Network SDK, featuring:

• TypeScript scripts for chain interaction
• Job handlers for management operations
• Secure configuration management
• Event-driven architecture

Security Considerations

• One-time initialization for critical components
• Role-based access control for management operations
• Protected configuration updates
• Secure key management requirements
