What Is Stargate V2?
Stargate is a cross-chain bridge and liquidity pool platform that facilitates seamless asset transfers between different blockchain networks ensuring IGF (Instant Guarantee of Finality). It was launched in March 2022 on LayerZero. Stargate V2 is a significant upgrade to the Stargate Protocol aiming to redefine the landscape of interoperability by offering enhanced features, improved security, and greater efficiency.
The Evolution of Cross-Chain Technology
The emergence of multiple blockchain networks has led to a growing need for interoperability. The TVL in DeFi is currently at $84 billion (as of August 2024), of which $48 billion is in Ethereum. Despite this concentration, a lot of funds are spread across a multitude of networks and chains. Cross-chain bridges have played a crucial role in connecting these disparate ecosystems, enabling users to transfer assets and interact with applications across different chains. Stargate V2 is a major step towards this cross-chain future, building upon the successes of its predecessor and addressing its limitations.
How Stargate V2 Works
Stargate V1 used to work on the Delta Algorithm, however was inefficient. Stargate V2 has introduced a concept called Planner that operates on a credit-based system ensuring efficient and secure cross-chain transfers. The core mechanism can be summarized in the following steps:
- Credit Allocation: Stargate maintains a pool of credits, which are essentially promises of future value. These credits are distributed across different chains based on factors like liquidity and demand.
- Asset Transfer: When a user wants to transfer assets from one chain to another, they deposit the assets on the source chain. The protocol then locks these assets and mints corresponding tokens on the destination chain.
- Credit Utilization: The transfer process consumes credits, which are deducted from the source chain’s credit balance.
- Credit Rebalancing: To maintain liquidity across chains, Stargate uses an AI Planning Module (AIPM) to dynamically adjust credit allocations. This helps ensure that there is sufficient liquidity on all chains to facilitate transfers.
Key Features of Stargate V2
Stargate V2 offers several key features that set it apart from other cross-chain bridges:
Cross-Chain Asset Transfer
Stargate V2 is a versatile cross-chain bridge that allows users to seamlessly transfer assets between various blockchain networks. One of its core features is the ability to facilitate cross-chain asset transfers. This means that users can easily move their assets from one blockchain to another, opening up new opportunities for trading, investing, and participating in decentralized applications (DApps) across different ecosystems.
Hydra, a key component of Stargate V2, plays a crucial role in enabling cross-chain transfers. Hydra is a bridging-as-a-service (BaaS) solution that allows new chains to integrate with Stargate more easily. This means that users can transfer assets to and from Hydra-enabled chains, expanding the reach and utility of Stargate.
Unified Liquidity Pools
Stargate maintains unified liquidity pools across multiple chains. This means that there is a single pool of liquidity that can be used for transactions on any of the supported chains. This helps to ensure that there is always sufficient liquidity available for users to transfer their assets, even if the liquidity on a particular chain is low.
Stargate Bus
Stargate Bus is a transaction batching mechanism that helps to reduce gas costs for users. By grouping multiple transactions together into a single batch, Stargate Bus can significantly lower the fees associated with cross-chain transfers. This makes it more cost-effective for users to transfer assets between different chains.
Credit-Based System
Stargate operates on a credit-based system. This means that users can transfer assets between different chains by using credits, which are essentially promises of future value. The protocol maintains a pool of credits that are distributed across different chains based on factors like liquidity and demand.
Dynamic Credit Allocation is a key feature of Stargate’s credit-based system. This allows the protocol to adjust the allocation of credits between different chains in real-time, ensuring that there is sufficient liquidity available for transactions on all chains. This helps to prevent bottlenecks and ensure that users can transfer assets efficiently and reliably.
AI Planning Module (AIPM)
The AI Planning Module (AIPM) is a sophisticated artificial intelligence system that helps to optimize the allocation of credits within Stargate. Credits are used to facilitate cross-chain transfers, and the AIPM ensures that they are distributed efficiently across different chains. This helps to prevent bottlenecks and ensure that there is always sufficient liquidity available for transactions.
Technical Innovations Behind Stargate V2
Stargate V2 is built on a solid technical foundation that incorporates several innovative elements:
Hydra: A Bridging-as-a-Service (BaaS) Solution
Hydra is a feature introduced in Stargate V2 that allows new chains to integrate with the protocol more easily. By leveraging the Omnichain Fungible Token (OFT) standard, Hydra enables chains to connect to Stargate without the need for extensive technical integrations.
Stargate Bus: Transaction Batching for Cost Reduction
The Stargate Bus is a transaction batching mechanism that reduces gas costs by 91% for users. By grouping multiple transactions together into a single “bus,” Stargate Bus can lower the overall cost of cross-chain transfers.
Planner: Credit Allocation
Unlike the on-chain credit allocation mechanism in Stargate v1, Stargate v2 introduces the concept of Planner. The Planner is responsible for dynamically allocating credits between different chains, ensuring optimal liquidity and competitive pricing. By offloading this task off-chain, Stargate v2 significantly reduces its capital requirements, making it more cost-effective than its predecessor. Further, the AI Planning Module (AIPM) ensures dynamic allocation of credits across different chains, ensuring that there is sufficient liquidity available for transactions. Importantly, the Planner is restricted to its role of allocating credits and cannot access or manipulate user funds, preserving the security of the bridge.
Stargate V1 vs V2: What’s the Difference?
Stargate V2 represents a significant upgrade over its predecessor, Stargate V1. The most notable differences between the two versions lie in their approaches to credit management, protocol visibility, adaptability, gas efficiency, capital efficiency, liquidity optimization, protocol fee management, operations and updates.

| Credit Oversight | Fully on-chain | On-chain with off-chain AI management |
| Flexibility | Limited route-based allocation | Active management across routes |
| Energy Efficiency | High gas consumption | Improved gas efficiency |
| Resource Optimization | Potential for underutilized credits | Optimized credit allocation for maximum usage |
| Liquidity Balancing | Limited ability to address imbalances | Enhanced liquidity management for optimal distribution |
| Fee Structure | Fixed fees regardless of usage | Dynamic fees are adjusted based on demand and value |
| Operational Efficiency | Manual, rule-based processes | Automated, data-driven operations |
