For compiling, building and deploying contracts to the network you will need cargo contract installed. Each network may be compatible with a different release of it.
To interact with current version of Aleph Zero Testnet, you will need cargo contract version 2.0.0-beta.1:
cargo install cargo-contract --version 2.0.0-beta.1
Latest releases of cargo contract are adding support for new arguments in Contracts::upload_code which has not been yet integrated into Aleph Zero chain.
Similarly, if you're using substrate-contracts-node, you need to be using version 0.22.1.
We've prepared a Docker image with required tooling to build contracts compatible with current Aleph Zero Testnet (contracts pallet at version 0.9.32). If you prefer to use it, take a look at https://github.com/Cardinal-Cryptography/docker-ink-dev.
