@ens:owner

Owner of an ENS name (the real owner when the name is wrapped).

On-chain (@ens:owner!): Mainnet only, since an assertion reads the chain it runs on, and an unowned name reads as the zero address rather than an error.

Returns: address

Syntax

@ens:owner(name)

Arguments

Name	Type	Description
name	string	ENS name (e.g. vitalik.eth)

Examples

# Get the owner of a name
set $owner @ens:owner("vitalik.eth")
print $owner

On-chain face (@ens:owner!)

Mainnet only. An assertion is judged on the chain it runs on, and there is no way to reach the ENS registry from another chain, so the on-chain face refuses at composition time rather than staticcalling an address with no code and reverting opaquely later.

Sepolia is refused too, deliberately. The plain face resolves against mainnet through a dedicated client, so a sepolia registry would answer about a DIFFERENT namespace: @ens:owner and @ens:owner! would return two unrelated answers and both would look right. Off mainnet, use the plain face — it resolves at composition time and is not restricted by the executing chain.

Notes

• Reads the registry word, so a name nobody owns is the zero address rather than an error. The plain face throws instead.
