This was a simple example using the escrow contract we developed, but it should show you what is possible. You are limited only by the wasm code you upload and the json messages you send. The next step is Hijack Escrow tutorial where you will edit a smart contract to put a backdoor that enables a thief to steal funds. If you want a guided tutorial to build a contract from start to finish, check out the name service tutorial.
There are a variety of curated video and tutorial resources, which you can check out here: Videos and Workshops
If you feel you understand enough (and have prior experience with rust), feel free to grab
cosmwasm-template and use that as a starting place to start hacking. Do not clone the repo, but rather follow the README on how to use
cargo-generate to generate your skeleton.
In either case, there is documentation in
cosmwasm that may be helpful. If you run into any issues (either bugs or just confusion), please submit them on
cosmwasm/issues if they deal with the smart contract, and
wasmd/issues if they have to do with the SDK integration.
