With the crypto world ever expanding, it’s natural to wonder where the future of crypto is. Well, here it goes—LI.FI, a multi-chain aggregator.

As we all know, currently many EVM chains are competing with each other, each having different features. In order to access the unique DeFi protocols only deployed on several chains, people need to transfer their assets from one chain to another frequently. 

It was based on this fact that Vitalik Buterlin said in the year 2016 that the future would be multi-chain. (Check his full argument here: https://twitter.com/VitalikButerin/status/1479501366192132099)

He believed that the future of crypto would be driven by the chain interoperability. According to him, we can go far beyond the approach most common in centralized systems of simply having an API from one chain to another, and in some cases even go so far as to have smart contract code on one chain to verify the consensus finality of events on other chains directly, requiring no trust in intermediaries at all (https://www.r3.com/wp-content/uploads/2017/06/chain_interoperability_r3.pdf).

That vision has become a reality today. A multi-chain aggregator called @lifiprotocol has cooperated with @etherspot, a multi-chain SDK provider. They simplified the process of cross-chain swaps. In the past, users had to change RPC frequently to match the network they wanted to interact with; but now, they can swap their assets between chains without changing RPC credit to Etherspot’s SDK.

This breakthrough creates massive value for users. I used to spend hours transferring assets from Gnosis chain to another chain in order to interact with dApps, which was unbearably boring and mistakes were common. However, the update of LI.FI handles this problem beautifully. For instance, @KlimaDAO is a protocol native to @0xPolygon, and users need to buy $KLIMA token to stake it in the vault to join the green revolution. What’s exciting now is that, what used to take users 9 interactions now becomes just 4, thanks to the updated version of LI.FI. Suffice it to say, the cross-chain swap makes a greener world.

In fact, the tech works in 4 steps.

1.Etherspot creates a smart contract wallet for the user on Polygon

2.The User sends their funds to this smart contract wallet

3.The User signs a message to swap to USDC and bridge using LI.FI

4.After bridging, the user again signs a message which swaps to Klima and stakes in a single batched transaction.

Moreover, with LI.FI and Etherspot’s joint SDK, we can donate for Ukraine more easily. The whole cross-chain swap notion makes users feel like we are using a single blockchain. The protocol will swap the token on other chains to ETH on the Ethereum chain to donate for Ukraine government. And this technology can be expanded to any-to-any cross chain swaps. The swap and bridge processes are arranged automatically.

The benefits of interop between chains are obvious. As Vitalik shows in his thesis, Interoperable chains open up a world where it is easy to move assets from one platform to another, to conduct payment-versus-payment and payment-versus-delivery schemes, and to access information from one chain inside another. These can even be implemented by third parties without any additional effort from the operators of the base blockchain protocols. We can imagine that the cooperation between LI.FI and Etherspot will bring the interop future to us. Here are some of its uses:

1.Yield aggregators can build cross-chain strategies

2.NFT Marketplaces can go cross-chain

3.Any protocol with pools/vaults can attract liquidity from any chain seamlessly.

In conclusion, I believe that LI.FI is a professional multi-chain swap&bridge aggregator which has incredible interoperability. LI.FI will play an important role in the multi-chain future to come.
