Stargate Finance is a cross-chain liquidity layer that solves the "Bridging Trilemma" (instant guaranteed finality, native assets, and unified liquidity). Unlike traditional bridges that mint synthetic ("wrapped") assets on the destination chain, Stargate allows users to swap native tokens (e.g., USDC on Ethereum for USDC on Avalanche) directly. It achieves this by pooling native liquidity across chains and using LayerZero for lightweight cross-chain messaging to coordinate the pools.

The protocol has evolved significantly with the rollout of V2 and deep integration with LayerZero's updated infrastructure:

Stargate V2 & Hydra: The protocol fully deployed Stargate V2, featuring "Hydra." This update allows third-party asset issuers and chains to deploy their own Stargate-compatible bridges without needing Stargate to bootstrap the liquidity. This "Bridging as a Service" model allows unlimited asset expansion beyond the core stablecoin pools.

Bus Mode (Cost Reduction): V2 introduced "Bus Mode," a mechanism that batches multiple small transfers into a single transaction on the destination chain. This design is intended to reduce gas costs for retail users by distributing the verification fee across multiple passengers in the "bus."

Solana & non-EVM Expansion: Following the LayerZero V2 integration in 2025, Stargate expanded native asset swaps to Solana and Aptos. This integration allows for direct settlement of native assets on non-EVM chains without complex intermediary hops.

The STG token utilizes a Vote-Escrow model to align long-term governance:

Governance (veSTG): Holders must lock STG for up to 24 months to receive veSTG. This grants voting power to direct protocol emissions and approve new chain deployments.

Fee Protocol: Stargate charges a transfer fee (typically roughly 6 basis points) on non-STG transfers. The DAO determines how these protocol revenues are allocated (e.g., to the treasury, liquidity providers, or buyback mechanisms).

Liquidity Mining: STG is used to incentivize liquidity providers (LPs) to deposit stablecoins and ETH into the unified pools, ensuring deep liquidity for bridge users.
