Function create_simple_did 

pub fn create_simple_did(
    ctx: &mut SpendContext,
    funding_coin: Coin,
    owner: Owner,
) -> DidResult<DidSpend>

create_did with the common defaults: no recovery list, a single required verification, and nil metadata. The usual entry point for a DID that does not need a recovery configuration.

The funding coin becomes the DID, in full

This delegates to create_did, so its funding-coin contract applies unchanged: the singleton’s amount is the coin’s ENTIRE amount, it MUST be odd, and any excess is locked in the DID forever. Pass a coin pre-split to exactly the intended amount.
