How It Works

Auctions

1. 24-hour auctions - New auction starts immediately after previous settles
2. Reserve price - First bid must meet reserve (~0.0008 ETH)
3. Bid increments - Each bid must be 10% higher than previous
4. Time extension - Bids in last 15 minutes extend auction by 10 minutes
5. Refunds - Previous bidder automatically refunded when outbid

Governance

1. 1 NFT = 1 vote - Each BASED DAO NFT gives you one vote
2. Proposal threshold - Need 4 NFTs to create proposals
3. Voting delay - 1 day after proposal creation before voting starts
4. Voting period - 4 days to cast votes
5. Delegation - Must delegate your NFTs to vote (usually to yourself)
