# ZEDX on Other Chains

Interoperability with other major blockchains is important for the growth of Zedx and the prospects of realizing its vision. One of the ways of securing it is through enabling the versions (wrappers) of ZEDX on other chains.

Unlinke ZEDX on Zedx, those wrappers are ZED20 tokens are created whenever someone locks a certain number of tokens on the Zedx and gets issued the exact same amount of wrapper tokens on the target blockchain. If a user withdraws the wrapper from the target blockchain, the tokens burned and the ZEDX tokens on Zedx are unlocked.

Currently, wrapped versions of ZEDX token exist on Ethereum (mainnet), Binance Smart Chain and the Arbitrum One layer-2 optimistic rollup chain for Ethereum. The latter is a wrapper of a wrapper powered by the Ethereum-Arbitrum bridge and its withdrawals from Arbitrum are subject to the optimistic rollup rules.
