Crypto Bridges Comparison 2025: Stargate vs Squid Router vs DeBridge vs Across

The blockchain ecosystem has evolved into a multi-chain world where different blockchain networks operate as isolated islands. While this diversity brings innovation and specialization, it creates a significant challenge: how do you transfer assets between these different networks? Crypto bridges connect these networks, establishing a vital connection for interoperability. This connection is essential infrastructure, enabling communication and asset transfers across the vast blockchain landscape.

In this comprehensive comparison, we’ll examine four leading crypto bridge platforms: Stargate, Squid Router, DeBridge, and Across. We’ll analyze their security mechanisms, supported blockchain networks, and user experience to help you make an informed decision about which bridge best suits your cross chain activity requirements. These platforms enable communication between blockchains, allowing them to communicate and transfer assets securely.

Types of Bridges

There are several main types of bridges that facilitate cross chain transactions, each with its own approach to security and functionality. Centralized bridges, also known as trusted bridges, rely on a central authority or entity to manage and verify asset transfers between chains. While these bridges can offer fast and straightforward transfers, they introduce a single point of trust, which can be a security risk. Centralized bridges create single points of failure that can be exploited by attackers, leading to security breaches and loss of funds.

In contrast, trustless bridges use smart contracts and decentralized protocols to eliminate the need for a central authority. These bridges are considered more secure and transparent, as they rely on code and consensus mechanisms rather than human intermediaries. 

Trustless bridges are especially valued in the world of decentralized finance, where eliminating trust assumptions is essential for secure asset transfers. However, blockchain bridges, including trustless ones, are vulnerable to smart contract exploits that can result in significant asset loss.

Stargate revolutionizes cross chain bridging by enabling native asset transfers without the complexity of wrapped tokens. Built on LayerZero’s infrastructure, it uses a sophisticated Delta algorithm that optimizes liquidity distribution across different blockchain networks.

The platform’s unique approach eliminates the traditional lock-and-mint mechanism that most bridges rely on. Instead, Stargate maintains liquidity pools of native assets on each supported chain, allowing users to swap directly between native USDC, USDT, and ETH across networks. With Stargate, users can move digital dollars—such as USDC and USDT—across chains, making it convenient to access funds instantly in digital dollars or local currency for international transactions. For instance, a user might bridge digital dollars from Ethereum to Solana to participate in DeFi opportunities with lower fees and faster transaction speeds.

Stargate currently supports 13+ chains including Ethereum, BNB Chain, Avalanche, Polygon, Arbitrum, and Optimism. The platform focuses primarily on EVM-compatible networks, ensuring smooth integration with existing Ethereum-based applications and smart contracts.

DeBridge - Cross-Chain Infrastructure

DeBridge combines asset bridging with arbitrary data transfer capabilities through its validator network consensus mechanism. The platform emphasizes economic incentives for security, with validators required to stake tokens that can be slashed for malicious behavior.

The protocol supports both simple token transfers and complex smart contract interactions across chains. For example, a user can utilize DeBridge to transfer USDC from Ethereum to Polygon and automatically execute a smart contract to provide liquidity on a decentralized exchange upon arrival. Its auto-execution feature allows users to program actions that occur automatically after bridging, such as swapping tokens or providing liquidity on the target chain.

Across utilizes an optimistic verification system combined with a competitive relayer network to achieve fast transaction processing. This approach allows for near-instant transfers while maintaining security through dispute resolution mechanisms and economic guarantees.

The protocol integrates with UMA’s oracle system, which provides economic guarantees for transaction validity. If disputes arise, the system can resolve them through UMA’s proven dispute resolution process, ensuring that incorrect transactions can be challenged and corrected.

Across focuses on capital efficiency by allowing relayers to front transactions and get reimbursed later, reducing the need for large locked funds on each chain. This model enables competitive fees and faster transaction times, particularly for frequently used routes.

The platform supports 8+ chains with particular emphasis on Ethereum Layer 2 networks including Arbitrum, Optimism, and Polygon. This focused approach allows Across to optimize specifically for the growing L2 ecosystem while maintaining high performance.

Bridge Architecture

The architecture of a blockchain bridge is fundamental to its security and efficiency. At its core, a bridge typically involves a locking mechanism on the source chain, which securely locks the original asset before any transfer occurs. Once the asset is locked, the bridge’s minting mechanism creates a corresponding wrapped token on the target chain, representing the original asset in the new environment.

When users wish to move their assets back, the bridge employs a burning mechanism on the target chain to destroy the wrapped token, followed by an unlocking mechanism on the source chain that releases the original asset. This process ensures that the total supply of the asset remains consistent across chains, preventing double-spending and maintaining security.

Smart contracts and decentralized protocols play a crucial role in this architecture, automating the entire process and ensuring that cross chain transactions are transparent, secure, and resistant to censorship. By leveraging these technologies, bridges can facilitate the seamless transfer of assets between chains while minimizing risks and maintaining the integrity of the original asset.

Security Comparison: Protection and Trust Mechanisms

Multi-Signature and Validation Systems

Security represents the most critical factor when choosing crypto bridges, as these protocols often custody billions of dollars in crypto assets. Each platform in our comparison implements different security models with varying trade-offs between decentralization and operational efficiency.

Stargate inherits its security from LayerZero’s oracle and relayer validation system. This approach eliminates traditional validator sets by requiring independent verification from both oracle networks and relayers. The system’s security depends on the assumption that oracles and relayers won’t collude, creating multiple independent verification layers.

Squid Router maintains security through decentralized smart contracts and rigorous validation processes embedded within its routing protocol. By aggregating liquidity from multiple sources and routing transactions via trustless mechanisms, it minimizes risks associated with centralized points of failure.

DeBridge employs a validator consensus mechanism where validators must stake tokens that can be slashed for malicious behavior. This economic security model aligns validator incentives with network security, as validators lose money if they approve fraudulent transactions. The system requires a majority of validators to approve cross chain transactions.

Across uses UMA’s optimistic oracle system, which provides economic guarantees through its dispute resolution mechanism. This model assumes transactions are valid unless challenged, with economic penalties for submitting false claims. The system’s security relies on active monitoring by network participants who can challenge incorrect transactions.
