Vitalik: Fragmentation does not destroy Defi's composability

On October 10th, Ethereum founder Vitalik forwarded an article with a theme of Cross-shard Defi composability and commented that "Sharding does not destroy Defi's composability." He pointed out that there have been recent concerns about whether Ethereum's "combinability" attribute (basically the ability to easily talk between different applications) will remain in the ETH 2.0 cross-sliced ​​background. He believes that the answer is yes, and to a large extent will be like this.
