Stargate vs Across: Bridge Liquidity

Single pool per asset: Enables native asset bridging (e.g., USDC on Ethereum to native USDC on Arbitrum) with deep, shared liquidity. This matters for large-volume DEX traders and arbitrageurs who need predictable, low-slippage transfers across 15+ chains.

Speed via bonded relayers: Users are refunded instantly by relayers, with finality secured later via an optimistic fraud-proof window on Ethereum. This matters for end-users and DeFi protocols prioritizing sub-2-minute finality for time-sensitive operations like liquidations or arbitrage.

Cons: Relies on the security of the LayerZero Endpoint and its Oracle/Relayer set. A failure in this decentralized validator network could affect all connected chains. This is a consideration for CTOs with strict security thresholds for moving $1M+.

Cons: Security is ultimately anchored to the Ethereum L1 via a 2-hour fraud-proof window. While capital-efficient, this introduces a latency for full settlement and trust assumption in relayers' bonds. This matters for protocols that require instant, cryptographically guaranteed finality.

Single-sided liquidity model: Liquidity providers (LPs) deposit into a single asset pool (e.g., USDC) that services all supported chains. This creates deep, shared liquidity, reducing fragmentation. This matters for high-volume DEXs and yield aggregators like PancakeSwap and Pendle that require consistent, large-capacity bridging for stablecoin operations.

Capital efficiency via bonded relayers: Uses a system of bonded relayers who front funds instantly, with disputes settled optimistically on Ethereum. This decouples liquidity from security, enabling high throughput with lower locked capital. This matters for institutional arbitrage and high-frequency strategies where speed and cost on non-EVM chains (like Arbitrum) are critical.

Tightly coupled with LayerZero: Security and liveness are intrinsically tied to the LayerZero protocol and its Oracle/Relayer set. A failure or exploit in LayerZero would directly compromise Stargate. This matters for protocol architects who prioritize modularity and seek to minimize systemic risk from a single stack dependency.

LP returns are variable and indirect: Liquidity Providers earn from relayer fees and UMA dispute rewards, which are less predictable than direct swap fees. The optimistic security model also requires understanding bond disputes. This matters for passive liquidity providers accustomed to straightforward AMM fee models, as it adds operational and cognitive overhead.

Unified liquidity pools: A single pool on each chain (e.g., USDC) services all destination chains. This provides deep, predictable liquidity for major assets, enabling large transfers (often $1M+) with minimal slippage. Ideal for high-volume DEX aggregators and institutional arbitrage.

Competitive liquidity sourcing: Relayers bid from on-chain liquidity (e.g., Aave, Compound, Uniswap) to fulfill transfers, creating a capital-efficient system. No locked capital in bridge contracts. This results in consistently lower fees for users and is optimal for frequent, smaller transactions and gas-efficient messaging.

Deterministic finality: Uses LayerZero's ultra-light nodes for sub-2 minute confirmations. This speed enables native cross-chain composability—critical for protocols like PancakeSwap v3 and Radiant Capital that require atomic or near-atomic execution across chains.

Bonded relayers with fraud proofs: A 1-2 hour optimistic window allows for cryptographic fraud proofs, slashing malicious actors. Combined with UMA's oracle for price feeds, this creates a strong cryptoeconomic security model preferred by risk-averse DAOs and institutional custodians moving treasury assets.

Deep DeFi integration: As part of the LayerZero/Stargate ecosystem, it's the default bridge for major protocols like Trader Joe, Angle Protocol, and Radiant. This creates strong network effects and ease of integration for new projects building omnichain applications.

Broad, non-opinionated reach: Supports chains without requiring native liquidity deployment (e.g., zkSync Era, Base, Metis). The model is agnostic to the source of liquidity, making it faster to integrate new chains and assets, ideal for experimental L2s and niche asset bridges.
