# What is MES Protocol?

MES Protocol is a cross-chain bridge for **FAST and CHEAP transactions across chains**.

**Why did we build MES?**

There are now over 1,000 blockchains, from Layer 1 to Layer 2 and even Layer 3 blockchains, which were non-existent during the earlier stages.

Each blockchain has its own consensus mechanism and data structure, to **navigate multiple blockchains can be complex**, even for crypto natives.\
\
In addition, dapps and liquidity **fragmentation is inevitable** with the state of the multichain.\
\
We aspire to build MES to **facilitate interchain interoperability and asset movements** between networks.
