One method to achieve this is by enabling wrapped versions of ECROX tokens on other chains. Unlike ECROX tokens on Ecrox, these wrapped tokens, known as ECROX-20 tokens, are created when a user locks a specific quantity of tokens on Ecrox. In return, they receive an equal amount of wrapper tokens on the target blockchain. When a user withdraws these wrapper tokens from the target blockchain, the corresponding tokens are burned, and the locked ECROX Coins on Ecrox are unlocked. Currently, wrapped versions of ECROX tokens are available on Ethereum (mainnet), Binance Smart Chain, and Arbitrum One (a layer-2 optimistic rollup chain for Ethereum). The Arbitrum version is unique as it's a wrapper of a wrapper facilitated by the Ethereum-Arbitrum bridge, and withdrawals from Arbitrum are governed by optimistic rollup rules. This interoperability enhances Ecrox's accessibility and utility across different blockchain ecosystems, broadening its reach and potential use cases. --- # 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.ecroxscan.com/general/learn-about-the-fuse-platform/fuse-token/fuse-on-other-chains.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.
