ENSSubnameIssuer

Title: ENSSubnameIssuer

Authors: David Dada <daveproxy80@gmail.com> (https://github.com/dadadave80), Modified from ENS (https://github.com/ensdomains/ens-contracts), Integrates the ENS NameWrapper (https://docs.ens.domains/wrapper/overview)

Stateless Diamond facet letting a diamond that owns a parent ENS name mint subnames (e.g. treasury.myproto.eth) via the ENS NameWrapper.

All logic lives in ENSSubnameIssuerLib. Issuance is gated on ENS_SUBNAME_ISSUER_ROLE; the NameWrapper is supplied at init and rotated per chain via setNameWrapper.

Functions

issueSubname

Mints label.<parent> via the NameWrapper, owned by owner with resolver set.

Gated on ENS_SUBNAME_ISSUER_ROLE. The diamond must own/approve parentNode in the NameWrapper. To make the subname forward-resolve, the owner sets the addr record on resolver; the child sets its reverse record via a future ENS reverse-record module.

function issueSubname(
        bytes32 parentNode,
        string calldata label,
        address owner,
        address resolver,
        uint64 ttl,
        uint32 fuses,
        uint64 expiry
    ) external virtual returns (bytes32);

Parameters

Name	Type	Description
parentNode	`bytes32`	The parent name's node (wrapped + controlled by this diamond).
label	`string`	The subname label.
owner	`address`	The owner of the new subname.
resolver	`address`	The resolver to set for the new subname.
ttl	`uint64`	The TTL for the new subname.
fuses	`uint32`	The fuses to burn on the new subname.
expiry	`uint64`	The expiry timestamp for the new subname.

Returns

Name	Type	Description
<none>	`bytes32`	The newly created subname's node.

setNameWrapper

Sets or rotates the NameWrapper (per-chain configuration).

Gated on ENS_SUBNAME_ISSUER_ROLE. Reverts ENSSubnameIssuerZeroNameWrapper for zero.

function setNameWrapper(address nameWrapper_) external virtual;

Parameters

Name	Type	Description
nameWrapper_	`address`	The NameWrapper to use.

nameWrapper

Returns the configured NameWrapper.

function nameWrapper() external view virtual returns (address);

Returns

Name	Type	Description
<none>	`address`

exportSelectors

ERC-8153 selector export: this facet's cuttable selectors, tightly packed (4 bytes each).

Excludes exportSelectors() itself (0x0ef22643) - it is never cut into a diamond. Order matches forge inspect ENSSubnameIssuer methodIdentifiers (alphabetical by signature); kept in exact parity by ExportSelectorsParityTest. Chunks: issueSubname(bytes32,string,address,address,uint64,uint32,uint64) 0xf15cd0d2 nameWrapper() 0xa8e5fbc0 setNameWrapper(address) 0x371412f1

function exportSelectors() external pure virtual returns (bytes memory selectors);

Returns

Name	Type	Description
selectors	`bytes`
