Let's compile the smart contract.
cargo +nightly contract build
Then, you can see something like this:
Once the compilation is completed, a
target folder is created. In this folder, under the
ink subdirectory, you will be able to see a
my_contract.wasm file and a
my_contract.wasm is your contract that has been compiled to web assembly and the
metadata.json is a JSON abstraction of your contract.
Any questions? Feel free to ask us.
