EVM Chain Interactions

The evm.Client is the Go SDK's interface for interacting with EVM-compatible blockchains. It provides a simple, powerful, and type-safe way to read data from and write data to your onchain contracts through the underlying EVM Read & Write Capabilities.

How it works

The Go SDK uses auto-generated contract bindings created by the CRE CLI. These bindings provide:

• Type-safe Go structs for contract functions and events
• Automatic ABI encoding/decoding
• Promise-based async operations with .Await()
• Built-in helper methods for common operations

This approach gives you IDE autocompletion, compile-time type checking, and eliminates manual ABI handling.
