@union_build builds with IBC.
Yes , the  Inter-Blockchain Communication Protocol.

Here's Why 👇

Firstly what is IBC ?
 IBC is a system that allows different blockchains to communicate securely and reliably. it's built straight into Cosmos.
So any blockchain using the Cosmos Software Development Kit (aka the Cosmos SDK) can easily use IBC.

But IBC is not limited to Cosmos, it can also communicate with other ecosystems (Avalanche, Polkadot, Ethereum, etc).

With liquidity and users scattered across different networks, a universal standard protocol is essential.

Hence, the need for Union to bring them all together under one standard.

Union is where everyone from any chain meets
