Engineering ⌐◫-◫

The most important theme of 2023 is going to be composability. The next generation of apps is going to leverage a multitude of composable crypto primitives to deliver experiences that were not possible before.

We live in a multi-polar world. We will never go back to a unipolar world. And that means that bridging is going to be extremely important. In addition to the LayerZero protocol, the LayerZero team is launching a cross-chain bridge called Stargate that is built on the LayerZero protocol. A simple mental model of Stargate is a cross-chain, stable swap DEX, similar to Curve or Saber. If a user wants to move USDC from Arbitrum to Optimism or from Polygon to Aurora (Near), now they can just use Stargate. While Stargate is the flagship app built on the LayerZero protocol, we expect the LayerZero protocol to power all kinds of new workflows. Because LayerZero is a generalized message-relaying service, it can be used for almost anything. Some examples:

1. Vote for governance proposals on Chain A using assets that are on Chain B without moving the assets back to Chain A

2. Use collateral on Chain A to take out a loan on Chain B

3. Use collateral on Chain A to collateralize a derivatives position on Chain B

4. Apply a mutation to an NFT on Chain A based on an on-chain action on Chain B

LayerZero is live today on most major EVM chains: Ethereum Layer 1, Optimism, Arbitrum, Polygon, Avalanche, Fantom, and BNB Chain. Additionally, LayerZero will be launching support for Celo, Aurora (Near), Solana, and Cosmos. In a perfect world, LZ will be adopted by TW.
