Function create_did 

pub fn create_did(
    ctx: &mut SpendContext,
    funding_coin: Coin,
    owner: Owner,
    recovery_list_hash: Option<Bytes32>,
    num_verifications_required: u64,
    metadata: HashedPtr,
) -> DidResult<DidSpend>

Mints a brand-new DID, fully settled and wallet-parseable, from a funding coin.

Spends funding_coin (owned by owner) to create the launcher, launches the eve DID with the given recovery configuration and metadata, then performs the owner-update (“settle”) spend that confirms the DID for wallets. Returns a DidSpend whose child is the fully-created, spendable Did.

Signature

Two AGG_SIG_ME signatures are required, both under whichever key/spend owner names (SPEC §3): one over the funding-coin spend (which creates the launcher) and one over the settle spend (which confirms the DID for wallets). Both are coin-bound AGG_SIG_ME, never AGG_SIG_UNSAFE.

Errors

Propagates any chia-wallet-sdk driver failure (currying, spend construction) as crate::DidError::Driver.

Owner::Custom

When using Owner::Custom(spend), the ONE caller-supplied inner spend is used for BOTH the funding-coin spend and the settle spend. The caller is responsible for ensuring the custom spend emits all conditions needed to satisfy both steps; conditions are not added by dig-did for a custom spend. A custom create-spend that omits required conditions will fail closed with a parse error, never a custody leak.
