Domain Operations

Contract: NameRegistry.CheckAddress

Checks that there is a valid domain record with the specified name and the address.

Entrypoint: check_address

Parameter	Type	Description
name	bytes	The UTF-8 encoded name to check.
address	address	The expected address.

CameLIGO

type check_address_param = [@layout:comb] {
    name: bytes;
    address: address
}

(* Checks that a name corresponds to an address. *)

Error	Description
AMOUNT_NOT_ZERO	The transferred amount of tez is not zero.
NAME_ADDRESS_MISMATCH	There is no valid domain record with the specified name or it resolves to an address different from the expected one.

Contract: NameRegistry.ClaimReverseRecord

Claims a reverse record corresponding to a domain (a forward record). The claimed reverse record will map the sender's address to the specified domain name.

Entrypoint: claim_reverse_record

Parameter	Type	Description
name	bytes	The UTF-8 encoded name to claim.
owner	address	The owner of the record allowed to make changes.

CameLIGO

type claim_reverse_record_param = [@layout:comb] {
    name: bytes option;
    owner: address;
}

| Claim_reverse_record of claim_reverse_record_param

Error	Description
AMOUNT_NOT_ZERO	The transferred amount of tez is not zero.
NAME_ADDRESS_MISMATCH	There is no domain record with the specified name or it resolves to an address different from the sender's address.

Contract: NameRegistry.SetChildRecord

Creates or overwrites an existing domain record. The current sender must be the owner of the parent record.

If there was an existing corresponding reverse record referencing this domain and the address of this domain changed, the reverse record's name will be updated to None to preserve consistency.

Entrypoint: set_child_record

Parameter	Type	Description
label	bytes	The UTF-8 encoded label.
parent	bytes	The UTF-8 encoded parent domain.
address	address option	The optional address the record resolves to.
owner	address	The owner of the record allowed to make changes.
data	(string, bytes) map	A map of any additional data clients wish to store with the domain.
expiry	timestamp option	The expiry of this record. Only applicable to second-level domains as all higher-level domains share the expiry of their ancestor 2LD.

CameLIGO

type set_child_record_param = [@layout:comb] {
    label: bytes;
    parent: bytes;
    address: address option;
    owner: address;
    data: (string, bytes) map;
    expiry: timestamp option;
}

| Set_child_record of set_child_record_param

Error	Description
AMOUNT_NOT_ZERO	The transferred amount of tez is not zero.
PARENT_NOT_FOUND	There is no record for the specified parent domain.
NOT_AUTHORIZED	The current sender is not the current record owner.
INVALID_LABEL	The given label is not valid. See Label Validation.
LABEL_EMPTY	The given label is empty.
LABEL_TOO_LONG	The label is too long.
NAME_TOO_LONG	The name (label + parent) is too long.

Contract: NameRegistry.UpdateRecord

Updates an existing domain record. The current sender must be its owner.

If there was an existing corresponding reverse record referencing this domain and the address of this domain changed, the reverse record's name will be updated to None to preserve consistency.

Entrypoint: update_record

Parameter	Type	Description
name	bytes	The UTF-8 encoded name of the domain to update.
address	address option	The optional new address the record resolves to.
owner	address	The new owner of the record allowed to make changes.
data	(string, bytes) map	The new map of any additional data that clients wish to store with the domain.

CameLIGO

type update_record_param = [@layout:comb] {
    name: bytes;
    address: address option;
    owner: address;
    data: (string, bytes) map;
}

| Update_record of update_record_param

Error	Description
AMOUNT_NOT_ZERO	The transferred amount of tez is not zero.
RECORD_NOT_FOUND	There is no domain record for the specified name.
NOT_AUTHORIZED	The current sender is not the current record owner.

Contract: NameRegistry.UpdateReverseRecord

Updates an existing reverse record. The current sender must be its owner. There must be a corresponding domain record.

Entrypoint: claim_reverse_record

Parameter	Type	Description
address	address	The address of the reverse record to update.
name	bytes option	The new UTF-8 encoded name the record resolves to.
owner	address	The owner of the record allowed to make changes.

}

| Update_reverse_record of update_reverse_record_param

Error	Description
AMOUNT_NOT_ZERO	The transferred amount of tez is not zero.
RECORD_NOT_FOUND	There is no reverse record with the specified address.
NOT_AUTHORIZED	The current sender is not the current record owner.
NAME_ADDRESS_MISMATCH	There is no domain record with the specified name or it resolves to a different address. This can occur only if the name is specified.
