# XP Wanchain’s XP is a non-transferable reputation system that tracks and measures user participation throughout the Wanchain ecosystem. XP is earned automatically whenever a user completes a cross-chain transaction using one of Wanchain’s cross-chain products, such as [WanBridge](/products/wanbridge.md) and [XFlows](/products/xflows.md). XP is earned with each cross-chain transactions, based on the following formula: * 100 XP per cross-chain transaction * 1 XP for every $1 value transferred * 100 XP for every $1 value of [bridge fees](/the-convert-n-burn-system/bridge-fees.md) paid XP cannot be sold or moved between wallets. XP can be used to claim [Bridge-to-Earn](/products/wanbridge/bridge-to-earn.md) tasks and earn rewards. Other use cases are in development. --- # 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.
