Streamline Flow Blockchain Development with Cadence to Go

When building applications on the Flow Blockchain, interacting with smart contracts from a Go backend requires precise type mapping and script execution logic. Our Cadence to Go tool automates the generation of Go structures and boilerplate code from your Cadence snippets. Bridge the gap between your on-chain logic and your Go services in seconds.

Key Features for Flow Developers

  • Type Mapping: Automatically converts Cadence types (Address, String, UFix64, etc.) into their Go equivalents or Flow-SDK compatible types.

  • Struct Generation: Transforms Cadence structs and resources into Go structs for easy JSON marshalling and data handling.

  • Binding Boilerplate: Generates the necessary Go code to call functions, send transactions, and query scripts using the Flow Go SDK.

  • Secure & Fast: Your smart contract code is processed locally, ensuring your proprietary logic remains private.

How to Use the Cadence to Go Tool

  1. Paste Cadence Code: Input your Cadence contract, transaction, or script into the editor.

  2. Define Package Name: Specify the Go package name for the generated output.

  3. Generate: The tool parses the Cadence logic and maps the signatures to Go functions.

  4. Integrate: Copy the generated Go code into your project and start interacting with the Flow network.

Why Automate Cadence to Go Conversion?

Manual translation of Cadence types to Go is not only time-consuming but also a primary source of runtime errors in blockchain applications.

1. Accuracy in Type Handling

Cadence has unique types like UFix64 and Address that require specific handling in Go. Our tool ensures that these types are correctly mapped to prevent precision loss or decoding failures during transaction execution.

2. Rapid Prototyping

Instead of manually writing wrapper functions for every smart contract update, you can simply re-run your code through the converter. This allows for a much faster development cycle when iterating on Flow transactions and scripts.

3. Reduced Boilerplate

Interacting with the Flow Go SDK involves significant setup for arguments and responders. Our tool generates the "glue code" automatically, allowing you to focus on your application logic rather than integration details.

Frequently Asked Questions

Which Cadence versions are supported?

The tool is kept up-to-date with the latest Cadence 1.0 syntax and stable releases, ensuring compatibility with the current Flow Mainnet environment.

Does it handle Cadence Resources?

While Go cannot replicate Cadence's resource-oriented paradigm, the tool generates Go structures that represent the data held within resources, making them easy to query and display in your app.

Can I use the output with the official Flow Go SDK?

Yes. The generated code is designed to be used directly with the github.com/onflow/flow-go-sdk, utilizing standard patterns for arguments and transaction signing.

Pro Tips for Flow Integration

  • Consistent Naming: Use clear variable names in your Cadence code; our tool preserves these names in Go to maintain code readability across your stack.

  • Error Handling: Always check the returned errors in the generated Go functions, as blockchain interactions can fail due to network issues or gas limits.

  • Argument Sorting: Remember that Flow transaction arguments must be passed in the exact order defined in the Cadence source; our tool automates this ordering for you.
