Buys & Renewals

Contract: TLDRegistrar.Commit

Creates a commitment to buy a second-level domain without disclosing the actual name. This is implemented according to our commit&reveal scheme.

Entrypoint: commit

Parameter Type

Description

bytes

SHA-512 hash of a packed tuple of label, owner, and a random nonce corresponding to the intended buy (see TLDRegistrar.Buy). The hashed tuple is of the Michelson typepair (pair bytes address) nat. Having a random nonce prevents susceptibility to dictionary attacks.

AMOUNT_NOT_ZERO

The transferred amount of tez is not zero.

COMMITMENT_EXISTS

The given commitment exists. A commitment with a new nonce has to be generated.

Contract: TLDRegistrar.Buy

Buys a second-level domain based on previous commitment (see TLDRegistrar.Commit).

Entrypoint: buy

Amount restriction: The amount sent with this call has to be equal to the price of the domain. The price in mutez is calculated as standard_price_per_day * duration / 1000000.

Parameter

Type

Description

label

bytes

The UTF-8 encoded label of the second-level domain to buy.

duration

nat

Ownership duration represented in days.

owner

address

The new owner of the given domain.

address

address option

The optional address the given domain resolves to.

data

(string, bytes) map

A map of any additional data clients wish to store with the given domain.

nonce

nat

The chosen commitment nonce.

Error

COMMITMENT_TOO_OLD

The commitment is too old (older than configured age). Try recreating it again.

COMMITMENT_TOO_RECENT

The transferred amount is higher than the actual price.

Contract: TLDRegistrar.Renew

Renews second-level domain for requested duration.

Entrypoint: renew

Amount restriction: The amount sent with this call has to be equal to the price of the domain. The price in mutez is calculated as standard_price_per_day * duration / 1000000.

Parameter

Type

Description
