Module context 

Execution context accessors for contract runtime information.

This module provides functions to query the current execution context, including caller information, block data, and call parameters.

Available Context

• Caller: Who invoked this contract
• Owner: Who deployed/owns this contract
• Contract ID: This contract’s address
• Block data: Current height and timestamp
• Call value: Native tokens sent with the call
• Calldata: Function selector and arguments

Example

use truthlinked_sdk::context;

fn handle_execute() -> Result<()> {
    let caller = context::caller()?;
    let owner = context::owner()?;
     
    // Only owner can call this function
    if caller != owner {
        return Err(Error::new(ERR_UNAUTHORIZED));
    }
     
    let height = context::block_height()?;
    let value = context::call_value()?;
     
    // Process transaction...
    Ok(())
}
