As a result, it’s difficult to build seamless and secure connectivity between zk rollups and the EVM ecosystem. * True advances in zero-knowledge technology now make it possible to build zero knowledge EVM chains that provide the same benefits of zk-rollups and are also compatible with the robust native Ethereum infrastructure that developers are already familiar with. * True The number of active chains interconnected over IBC has grown steadily to\_\_\_ active chains. * 56 Which chain \_\_\_\_ has a vibrant NFT ecosystem and community with several hundred collections calling it home? * Solana BTC accounts for 46.1% of the entire industry’s value * True Deploying on multiple chains or providing the infrastructure to onboard users from any chain will allow dApps to: * All of the above Multi-chain DeFi middleware solutions like [LI.FI](http://LI.FI) offers a product that abstracts away cross-chain infrastructure by providing a tech stack to cater to every need * True **ze码：** Ze Code: 37582359123751295852 --- *Originally published on [ack](https://paragraph.com/@ack-2/li-fi)*
