This repository contains the source code of Neutron Cosmwasm SDK for interacting with Neutron blockchain
The Neutron SDK is contained inside packages folder and consists of the following subpackages:
| Package | Reference | Description |
|---|---|---|
| Neutron Interchain Queries | https://github.com/neutron-org/neutron-sdk/tree/main/packages/neutron-sdk/src/interchain_queries | Queries, messages and helper methods for interacting with Neutron Interchain Queries Module |
| Neutron Interchain Transactions | https://github.com/neutron-org/neutron-sdk/tree/main/packages/neutron-sdk/src/interchain_txs | Queries, messages and helper methods for interacting with Neutron Interchain Transactions Module |
| Neutron Bindings | https://github.com/neutron-org/neutron-sdk/tree/main/packages/neutron-sdk/src/bindings | Structures and helper methods for interacting with Neutron blockchain |
| Neutron Sudo | https://github.com/neutron-org/neutron-sdk/tree/main/packages/neutron-sdk/src/sudo | Structures for Sudo Contract callbacks from Neutron blockchain |
| Neutron Errors | https://github.com/neutron-org/neutron-sdk/tree/main/packages/neutron-sdk/src/errors | Structures and helpers for Neutron specific error and result types |
| Neutron Stargate | https://github.com/neutron-org/neutron-sdk/tree/main/packages/neutron-sdk/src/stargate | Structures and helpers for interacting with Neutron via Stargate |
We provide sample contracts that either implement or consume these specifications to both provide examples, and provide a basis for code you can extend for more custom contacts, without worrying about reinventing the wheel each time:
| Contract | Reference | Description |
|---|---|---|
| Neutron Interchain Queries Example Contract | https://github.com/neutron-org/neutron-sdk/tree/main/contracts/neutron_interchain_queries | The contract shows how to properly work with Interchain Queries Module using Interchain Queries SDK package via CosmWasm smart-contract. |
| Neutron Interchain Transactions Example Contract | https://github.com/neutron-org/neutron-sdk/tree/main/contracts/neutron_interchain_txs | The contract shows how to properly work with Neutron Interchain Transactions Module using Interchain Transactions SDK package via CosmWasm smart-contract. |
| Neutron IBC Transfer Example Contract | https://github.com/neutron-org/neutron-sdk/tree/main/contracts/ibc_transfer | The contract shows how to properly work with Neutron Sudo Package to handle a callback from IBC transfer. |
- Rust v1.78.0+
wasm32-unknown-unknowntarget- Docker
-
Install
rustupvia https://rustup.rs/ -
Run the following:
rustup default stable
rustup target add wasm32-unknown-unknown- Make sure Docker is installed
Each contract contains Rust unit tests embedded within the contract source directories. You can run:
make testmake schemaNeutron proto files represented as generated Rust code is a part of the Neutron SDK. In case Neutron proto files have changed there's a command for Rust generated code rebuild. To rebuild the files, run the following command:
make build-protoFor production builds, run the following:
make buildThis performs several optimizations which can significantly reduce the final size of the contract binaries, which will be available inside the artifacts/ directory.
