Nouns Vision Batch Transfer

Allows Nouns DAO to batch transfer Nouns Vision Glasses to pods, subdaos, etc. Deployed at 0x6ff4ff4fe59d7ec571f36e36961b032027e68cee on Mainnet.

How To Use

Nouns DAO

1. Once deployed, Nouns DAO must approve the NounsVisionBatchTransfer contract for all transfers

NounsVisionContract.setApprovalForAll( address(NounsVisionBatchTransfer), true)

2. Nouns DAO must add a batch transfer allowance for a Pod

NounsVisionBatchTransfer.addAllowance(POD_ADDRESS, 10);

Pod

Gift a Single Pair of Glasses

A Pod can choose to leave their Nouns Vision Glasses in the possesion of Nouns DAO and only transfer a pair when they have a designated recipient (e.g. after a giveaway). When that recipient address is known:

1. The Pod calls the getStartId() view function in Etherscan to get the startId paramater to use.

2. The Pod initiates the transfer using the startId and the recipient address

NounsVisionBatchTransfer.sendGlasses(startId, address)

Gift Many Pairs of Glasses

A Pod can choose to leave their Nouns Vision Glasses in the possesion of Nouns DAO and only transfer pairs when they have a designated recipients (e.g. after a giveaway). When the recipients' address is known:

1. The Pod calls the getStartId() view function in Etherscan to get the startId paramater to use.

2. The Pod initiates the transfer using the startId and an array recipient addresses ([0xabc..., 0xdef...])

NounsVisionBatchTransfer.sendGlasses(startId, addresses)

Claim an Amount of Glasses

Sends an amount of Glasses to the Pod's address

1. The Pod calls the getStartIdAndBatchAmount() view function in Etherscan with its own address to get the startId and amount parameters to use.

NounsVisionBatchTransfer.getStartIdAndBatchAmount(POD_ADDRESS)
=> startId, amount

2. The Pod initiates the batch transfer using the startId and any value up to the amount

3. The Pod can claimGlasses as many times as it has allowance to do so. For example, it can choose to transfer only half its allocation to save gas.

NOTE: NounsVisionBatchTransfer batches only continuous token Id transfers (i.e. 751-800). Due to transfers out of Nouns DAO and back in, there may not be a "continuous batch" of Nouns Vision Glasses to satisify a Pod's allocation. (ie. only tokenIds 777, 888, 900-1200 may be owned by Nouns DAO at any one time). It is possible that NounsVisionBatchTransfer.getStartIdAndBatchAmount(POD_ADDRESS) and NounsVisionBatchTransfer.claimGlasses(startId, amount) may need to be called several times to transfer the allowed amount of Nouns Vision Glasses.
