ens:create-subname

Create a subname under an ENS name you own.

⚗️ Experimental — available at next.evmcrispr.com.

Supports runtime fields inside smart blocks. Use explicit @helper! expressions or captured outputs; other fields are evaluated at build time.

Syntax

ens:create-subname <parent> <label> <owner>

Arguments

Name	Type	Evaluation	Description
parent	string	Build time	Parent ENS name (e.g. mydao.eth)
label	string	Build time	Subname label (e.g. vault for vault.mydao.eth)
owner	address	Runtime in smart blocks	Owner of the subname

Options

Name	Type	Evaluation	Description
--resolver	address	Runtime in smart blocks	Resolver for the subname (defaults to the parent's)
--fuses	number	Build time	Fuses to burn on the subname (wrapped parents only; use @ens:fuses)
--expiry	number	Runtime in smart blocks	Subname expiry timestamp (wrapped parents only)

Examples

load ens

# Give the treasury its own subname
ens:create-subname mydao.eth treasury 0x1234567890abcdef1234567890abcdef12345678

# Wrapped parent: burn fuses so the subname is out of the parent's control
ens:create-subname mydao.eth vault @me --fuses @ens:fuses("parent-cannot-control" "cannot-unwrap")

Notes

• The subname inherits the parent's resolver unless --resolver is passed.
• --fuses and --expiry require the parent to be wrapped in the NameWrapper.
