Marketplace V1.0.0

Introduction

The Marketplace ADO is a smart contract that allows you to sell your NFTs in a marketplace. The seller sends their NFT to the Marketplace ADO and attaches the sale options such as the price and funds used to purchase the NFT. Once the NFT is sent, the sale will start at the time specified by the seller.

Purchasing the NFT can be customized to work with one of the following options:

Native: By specifying the denom of the chain in the StartSale message.
CW20: By specifying the contract address of the CW20 token to be used in the StartSale. The CW20 tokens allowed to be set as the purchasing token can be restricted by specifying authorized_cw20_address at instantiation. If this is not specified, then any CW20 token can be set.

Each sale is assigned an Id which starts at 1 and increments for each new sale.

authorized_cw20_address

Option<AndrAddr>

Optional CW20 address to authorize to be used as the purchasing coin for the NFTs in the marketplace sale. If not specified, then any CW20 can be set as the purchasing coin.

Optional address to specify as the owner of the ADO being created. Defaults to the sender if not specified.

ExecuteMsg

ReceiveNft

Receives a token from a SendNft and starts an auction based on the given parameters in the StartSale struct.

This message is not called by the user on this ADO, but is the case that handles receiving NFTs from a CW721 ADO.

 pub enum ExecuteMsg {
  ReceiveNft(Cw721ReceiveMsg)
}

Cw721ReceiveMsg

pub struct Cw721ReceiveMsg {
    pub sender: String,
    pub token_id: String,
    pub msg: Binary,
}

The msg in the Cw721ReceiveMsg should be a base64 encoded binary of a Cw721HookMsg.

Start Sale

A CW721 hook message that starts a new sale with the given parameters.

pub enum Cw721HookMsg {
    StartSale {
     price: Uint128,
     coin_denom: String
     start_time: Option<MillisecondsExpiration>,
     duration: Option<MillisecondsDuration>,
     uses_cw20: bool,
     recipient: Option<Recipient>,
       }
   }

{
    "start_sale": {
          "price":"500000",
          "coin_denom": "uandr",
