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 This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.escher.finance/key-features/full-interoperability.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
