What kind of asynchronous DeFi projects can I create on the IC?

The Internet Computer blockchain expands the world of possibilities of decentralized finance in a multi-chain world. DeFi on the Internet Computer integrates with dapps and offers a seamless user experience with low fees.

The functions of different canister smart contracts run on a single call stack. This makes them very insecure, due to re-entrancy, which has been one of the biggest sources of hacks on blockchain to date. Another problem is that transactions must run in sequence, which creates a firm upper bound on transaction throughput. On the Internet Computer blockchain, smart contract calls run in parallel, because smart contracts are "software actors." This removes a key security vulnerability and provides for the unbounded, efficient scaling of blockchain computation.

You could create a 100% on-chain and scalable auction house for NFTs, or a decentralized exchange for tokens. Or a software library that helps others with the new way of coding DeFi. Or code that interacts with other blockchains.
