# Full Interoperability ### What is Full Interoperability? Escher.Finance enables users to liquid stake and redeem their tokens from anywhere, thanks to the interoperability capabilities of Union. This means seamless interaction between different blockchain networks without users needing to understand the underlying complexity—stake tokens from any supported chain, have them staked on any other chain, and receive liquid staking tokens (LSTs) wherever you prefer. The revolutionary aspect of Escher is the ability to **stake on one chain and redeem on another**. For example, you can stake ETH on Ethereum but redeem your liquid staking tokens on Base, or stake USDC on Arbitrum but unstake and receive your original assets on Optimism. ### Escher's Interoperability Architecture #### Cross-Chain Stake and Redeem Escher's architecture enables true cross-chain flexibility: * **Stake Anywhere**: Initiate staking from any supported chain * **Redeem Anywhere**: Unstake and receive tokens on any other supported chain * **Chain Independence**: Your staking position isn't tied to a specific chain * **Seamless Migration**: Move your liquidity between chains without losing staking rewards #### Union Chain as Router We have designed Escher's architecture to support a single version of the token as it moves through the Union chain, which acts as a central router: * **Centralized Token Management**: Single token version ensures consistency * **Efficient Routing**: Union chain optimizes cross-chain token flow * **IBC Mint-and-Burn Mechanism**: Utilizes proven Inter-Blockchain Communication protocol * **Liquidity Consolidation**: All liquidity flows through the Union router for maximum efficiency #### Universal LST Standard Escher LSTs (eTokens) work consistently across all supported chains: * Same functionality regardless of origin or destination chain * Composable with DeFi protocols on any chain * Standardized reward distribution mechanisms * Cross-chain transferability through Union's infrastructure --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
