Portals, one of the biggest improvements, allow users to swap assets from any blockchain on which Aave is deployed. Users can create “aTokens” – which represent deposits into Aave – on one chain and burn them on another. This feature opened up the possibilities of on-chain trading strategies, such as yield arbitrage, or taking advantage of the varying yields offered by the protocol on different blockchains.
