Cross-chain applications hit integration bottlenecks while integrating different chain types. The learning curve to integrate different wallet SDKs is very steep and littered with blockers. 

There are many different packages that are developed by each ecosystem and they have different interfaces.

Each cross-chain dapp would need to implement these interfaces again and again.

It's very crucial to support as many chains as possible in today's world. And Tangled helps reduce this overhead.

For a multi-chain dapp, the integration time for all 8+ chain types would be around 2 months. With Tangled, it comes down to just 2 days.
