Airdrop RCS

The following steps were followed to conduct the January 7th airdrop using our Random Collector Selector (RCS) smart contract via Chainlink.

  1. Snapshot: A CryptoCitizen token holder snapshot was taken at January 5th 12 PM PT.

  2. Snapshot Data: Token holder snapshot can be independently verified and has been uploaded to IPFS at this hash: QmQVcTWQTGGsqnRzkzzwFToSWMDJocXSJQ2WsS9DbZiTdV

  3. Generate Random Number: This smart contract was used to generate 1000 random numbers using Chainlink VFR (Verifiable Random Function). The output of this on-chain transaction can be verified on Etherscan here:

  4. Lookup Winners: Each generated number in step 3 was mapped to index number for each CryptoCitizen tokenID in the snapshot data found on IPFS in step 1. The first 333 matches are the winning TokenIDs.
