What are xAccounts?

xAccounts are an implementation standard for setting up accounts on chain A that are controlled by an account on chain B. Built using the Wormhole messaging bridge, xAccounts form the 4th building block of Wormhole followed by xAssets, xApps, and xData.

xAccounts share many similarities with Cosmos's Interchain Accounts (ICA):

• Ability to establish account controls xChain.

• Account hierarchies can be defined.

• Generic messages and contract calls can be relayed

but also offer certain differences:

v1 xAccount operations are all assumed to be asynchronous and non-atomic. Future iterations could utilize Wormhole's batch VAAs to achieve atomic execution.
