Building cross-chain apps sucks.

$U either rely on bridges (security risk), wrapped assets (trust issues), or deal with fragmented liquidity.

👇

What Union actually does :

No bridge. No multisig. No custodian.
Just pure cryptographic guarantees.

The core idea: Chain Abstraction
As a dev, $U build as if it’s one global execution layer.

Contracts don’t need to “know” they’re talking to a different chain.

The tech: ZK-powered settlement

This means :

☑️ No trusted relayers

☑️ Finality is cryptographic, not social

The experience for devs :

🔹Deploy contracts on supported chains

🔹Integrate Union’s SDK or messaging layer

🔹Send + verify messages across chains

🔹Build apps that scale beyond one L2

All while keeping the security of native chains.

Union’s infra is already running testnets between :

🔹Ethereum

🔹Polygon zkEVM

🔹Linea

and more coming🔜

Every modular or L2 project talks about interop ...

This is the missing layer for rollups, appchains, and L2s to work together.

So finally for devs it's :

🔹ZK messaging across chains

🔹No bridges or trusted parties

🔹Native finality + security

🔹Live testnets, working infra

🔹Abstraction = less cross-chain headache
