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.

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

duration
nat
Ownership duration represented in days.
owner
address
The new owner of the given domain.
address
address option
