Start with the tutorial for a complete guide to developing smart contracts for the Provenance Blockchain.
provwasm-std uses feature flags to allow you to include only the blockchain modules your contract needs. This significantly reduces compile times and binary sizes. By default, provwasm-std includes all Provenance modules and core Cosmos modules, but you can disable default features and enable only what you need.
For example, a minimal contract using only the name service:
[dependencies]
provwasm-std = { workspace = true, default-features = false, features = ["provenance-name"] }See FEATURES.md for a complete guide to available features, dependencies, usage examples, and optimization tips.
Once the tutorial has been completed and you are ready for a more advanced topic, checkout the IBC Overview to learn more about IBC Smart Contracts and a guided tour of a multi-contract IBC project.
In addition to the core CosmWasm functionality, the Provenance bindings include:
Since migrating to Stargate queries, only a subset of queries are responded to. The list is maintained in Provenance.
Provenance includes third-party protobuf definitions to maintain compatibility
