}

Interface for an Axelar Executable app.

Required Methods

fn gateway(env: &Env) -> Address

Return the trusted gateway contract id.

fn execute( env: Env, source_chain: String, message_id: String, source_address: String, payload: Bytes, )

Execute a cross-chain contract call with the given payload. This function must validate that the contract call is received from the trusted gateway.

Provided Methods

fn validate( env: Env, source_chain: String, message_id: String, source_address: String, payload: Bytes, )

Validate if a gateway has approved a contract call. This should be called from an implementation of execute before executing custom app logic. This method doesn’t get exposed from the contract, as Soroban SDK’s contractimpl macro ignores default trait methods.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
