LayerZero's flagship bridge app — unified liquidity pools with native asset transfers across chains.

Updated: February 16, 2026AI Model: claude-4-opusVersion 1

Overview

Stargate Finance is a cross-chain liquidity transport protocol and the flagship application built on LayerZero's messaging infrastructure. Launched in March 2022 by the LayerZero Labs team, Stargate solved a fundamental problem in cross-chain bridging: the fragmentation of liquidity across separate pools for each chain pair. Its unified liquidity pool model allows assets on any chain to draw from a shared pool, dramatically improving capital efficiency.

Stargate enables native asset transfers — users bridge real USDC, USDT, or ETH rather than wrapped synthetic versions. This eliminates the problem of fragmented wrapped token liquidity and provides a seamless user experience. The protocol guarantees instant finality: when a user initiates a transfer, they receive confirmation on the destination chain without risk of transaction reversion.

As LayerZero's most prominent application, Stargate serves as both a standalone bridge product and a composable liquidity layer that other DeFi protocols can integrate for cross-chain functionality. Its V2 upgrade (launched in 2024) introduced a new architecture with improved capital efficiency through a credit-based system and support for additional asset types.

Security

Bridge Architecture

Stargate inherits its cross-chain messaging security from LayerZero. Messages are verified by LayerZero's Decentralized Verifier Networks (DVNs), with Stargate using a security configuration that includes the LayerZero DVN plus additional verifiers. The protocol-level security includes pool rebalancing algorithms that prevent liquidity depletion on any single chain, and credit systems in V2 that manage cross-chain accounting. Smart contracts on each chain manage liquidity pools and handle deposit/withdrawal logic.

Audit History

Stargate contracts have been audited by Zellic, Quantstamp, and Code4rena. The underlying LayerZero protocol has its own audit history. Stargate V2 underwent fresh audits before launch. The protocol maintains bug bounty programs through both its own channels and Immunefi. Combined audit count across versions exceeds 8.

Exploit Track Record

Stargate has not suffered a direct protocol exploit, though it has faced incidents affecting its ecosystem. In 2023, a vulnerability in a peripheral contract was discovered and patched before exploitation. However, Stargate's security is coupled to LayerZero's DVN integrity — a compromise of LayerZero's verification layer would directly impact Stargate. The protocol's reliance on LayerZero means its security floor is set by LayerZero's weakest DVN configuration, not independently controlled.

Technology

Verification Method

Stargate V2 uses a credit-based system for cross-chain liquidity management. Rather than locking and minting tokens, the protocol maintains credit accounts across chains that track available liquidity. When a user bridges assets, Stargate burns credits on the source chain and mints them on the destination, with the actual asset transfer handled through the unified liquidity pools. Cross-chain message verification is delegated entirely to LayerZero's DVN architecture.

Supported Chains

Stargate supports 20+ chains including Ethereum, Arbitrum, Optimism, Base, Polygon, Avalanche, BNB Chain, Fantom, Metis, Linea, Scroll, Mantle, and Kava. Coverage spans major EVM L1s and L2s with deep liquidity on primary routes. V2 expanded chain support while maintaining liquidity depth through the credit system's more efficient capital allocation.

Speed & Cost

Transfer times range from 30 seconds to 5 minutes depending on the route and LayerZero message delivery. Stargate guarantees instant finality on the user-facing side — once the destination transaction is confirmed, it will not revert. Fees include a swap fee (typically 0.01-0.06%), a protocol fee, and destination gas costs. The unified liquidity model generally offers competitive pricing, especially for stablecoin transfers.

Decentralization

Validator Set

Stargate does not operate its own validator set — cross-chain verification is fully delegated to LayerZero's DVN infrastructure. The protocol team controls smart contract upgrades, pool parameters, and fee configurations. Pool rebalancing is algorithmic, but parameter adjustments and contract upgrades are managed by the core team with governance input.

Governance

The STG token provides governance over protocol parameters including fee structures, supported chains, pool configurations, and treasury spending. Governance uses a veSTG (vote-escrowed) model where users lock STG tokens for voting power, with longer lock periods granting more influence. In practice, large token holders (including the team and early investors) maintain significant governance influence.

Trust Assumptions

Users trust: (1) LayerZero's DVN configuration correctly verifies cross-chain messages for Stargate, (2) the Stargate smart contracts correctly manage liquidity pools and credit accounting, (3) the protocol team manages upgrades and parameters honestly, and (4) the unified liquidity pool has sufficient depth to honor withdrawals. The trust stack is layered — Stargate's security depends on both its own contracts and LayerZero's infrastructure.

Adoption

Volume

Stargate consistently processes $500M-$1B+ in monthly bridge volume, making it one of the top 3 bridges by transaction value. Cumulative lifetime volume exceeds $30B. USDC and USDT transfers dominate volume, followed by ETH and other native assets. The protocol serves as the backend for many bridge aggregator routes.

Market Share

Stargate holds approximately 15-20% of the cross-chain bridge market by volume, competing directly with Across, Wormhole, and native canonical bridges. It is the dominant bridge for stablecoin cross-chain transfers and the most-used application in the LayerZero ecosystem. Aggregator integrations (Socket, LI.FI) consistently route significant volume through Stargate.

Integrations

Stargate is integrated into major DeFi protocols and aggregators including Sushi (cross-chain swaps), Radiant Capital, Socket/Bungee, LI.FI, and numerous wallet providers. Its composable design allows other protocols to embed cross-chain liquidity transport directly into their smart contracts, making it a building block for multichain DeFi.

Tokenomics

Token Overview

The STG token has a total supply of 1 billion tokens. Distribution allocated 17.5% to an initial auction, 15.95% to the core team, 17.5% to investors, 15% to the protocol launch, 2.11% to early community participation, and the remainder to the Stargate treasury and future emissions. The veSTG model encourages long-term token locking, with approximately 35-40% of circulating supply locked in governance at peak.

Fee Model

Stargate generates revenue through bridge fees charged on each transfer — a combination of swap fees (paid to LPs) and protocol fees (accruing to the treasury). Fee rates vary by pool and route, typically 0.01-0.06% of the transfer amount. Liquidity providers earn swap fees proportional to their pool share. The fee structure in V2 was redesigned for better capital efficiency with dynamic fee adjustments based on pool balance.

Value Capture

STG captures value through the veSTG governance model — locked STG earns a share of protocol fees and directs emission rewards to specific liquidity pools. This creates demand from both governance participants and liquidity providers seeking to optimize their yields. However, ongoing emissions dilute non-staking holders, and fee revenue must be evaluated relative to token market cap for fundamental value assessment.

Risk Factors

  • LayerZero dependency: Stargate's security is entirely dependent on LayerZero's DVN infrastructure. A compromise of LayerZero's verification layer would directly enable attacks on Stargate's liquidity pools. Stargate cannot independently upgrade its cross-chain security.
  • Unified liquidity pool concentration: While capital-efficient, unified pools concentrate risk — an exploit could drain liquidity across all connected chains simultaneously rather than being isolated to a single chain pair.
  • Smart contract complexity: The V2 credit system introduces complex cross-chain accounting logic. Bugs in credit management could lead to imbalances that allow attackers to extract excess value from pools.
  • LP impermanent loss and depegging risk: Liquidity providers face risk if bridged assets depeg or if pool imbalances persist. During high-volatility events, pool rebalancing may not keep pace with demand asymmetry.
  • Governance concentration: Despite the veSTG model, large early holders maintain outsized governance influence. Protocol parameter changes affecting fee distribution or emissions could favor large stakeholders.
  • Competitive pressure: The bridge market is intensely competitive, with new entrants (intent-based bridges, ZK bridges) potentially offering superior economics. Margin compression could reduce fee revenue.

Conclusion

Stargate Finance established the unified liquidity pool model that has become the gold standard for cross-chain bridge design. Its native asset transfers, guaranteed finality, and composable architecture have earned it a position as one of the most-used bridges in crypto. The V2 upgrade's credit-based system further improved capital efficiency and expanded the protocol's capabilities.

However, Stargate's complete dependency on LayerZero's messaging infrastructure creates a layered risk profile — users are exposed to both Stargate's smart contract risk and LayerZero's DVN integrity risk. This is a fundamental architectural trade-off: Stargate benefits from LayerZero's broad chain support and messaging capabilities, but cannot independently control its cross-chain security guarantees.

For users, Stargate offers a mature, liquid, and well-integrated bridge experience, particularly for stablecoin transfers. The veSTG tokenomics model provides meaningful value capture for committed participants. But as with all bridges, the protocol sits at one of crypto's most critical and most targeted attack surfaces, and its layered dependency on LayerZero adds complexity to risk assessment.
