# Powered by Universal Accounts

UniversalX is built on top of Particle Network's Universal Accounts. These give users access to:

* A unified spendable balance across EVM chains and Solana.
* The ability to use any token from any chain on any dApp to pay for gas. By default, the system pre-selects the cheapest available route.
* Cross-chain, bridgeless transactions.
* Seamless onboarding for users, either connecting an existing wallet or a Web 2.0 social account.

### How do Universal Accounts work?

Universal Accounts’ unified balances and Universal Gas are made possible by a unique system called Universal Liquidity. In simple terms, Universal Liquidity routes users’ assets across chains on a per-transaction basis. \
\
This system relies on a system of liquidity pools deployed across multiple chains, which receives assets on their source chains, deducts a small fee, and then releases the equivalent amount of the necessary assets at the destination chain. \
\
This is showcased in detail below:
