A: Because 0x is not an application; it is a smart contract protocol and a set of developer libraries. You integrate it into your own application.
The method for downloading 0x v8.9.1 depends entirely on which component you need. There is no single “0x.exe” file; instead, you interact with the protocol via npm packages, Docker images, or direct GitHub releases. For air-gapped environments, you can download the source
If you are looking to integrate 0x v8.9.1 into your dApp:
If you need the raw Solidity smart contracts (for local compilation or auditing): Hash Verification (SHA-256): Always verify the integrity of
git clone https://github.com/0xProject/protocol.git
cd protocol
git checkout tags/v8.9.1
This will give you the exact state of the protocol repository as of the v8.9.1 release. You will find the smart contracts in contracts/ and the migration scripts in contracts/zero-ex/.
