Canonical Zoo Historical Context for Bridge / Token / Omnichain Papers

Source: Original Oct 2021 + Jan 2022 $ZOO Deck PDFs

Zoo Bridge Origins (Oct 2021 Q4 Roadmap)

• Zoo Bridge was in the original Oct 2021 Q4 roadmap: "Bridge between ETH and Binance"
• BSC bridge was the first one planned

Zoo Bridge Launch (Jan 2022 Roadmap)

• January 2022 roadmap confirmed: February 2022 = "ZOO Bridge" launch
• Original Jan 2022 deck description: "Our bridge allows each users to play ZOO on any chain. Creates a secure platform to exchange $ZOO for other assets"
• Listed asset icons: NEM, NEO, Dash, Litecoin, BitcoinCash, Zcash, Steem, Decred, Ethereum, XRP, EOS, Monero, Bitcoin, TRON, Dogecoin, Tether

Zoo NFT Origins

• Zoo NFTs started as ERC-721 on BSC (PancakeSwap integration for $ZOO and egg purchases)
• "Contains 1 of 16 Generation one Base Animals" — original collection was 16 generation-one base animals, expanded to 20 in later materials

Yield-Transferability via NFT Ownership (Original Innovation)

• Yield transferable via NFT ownership — token-bound-account predecessor pattern
• "NFT yield and collateral is transferable to new owners until the Animal is freed from ZOO"
• Freeing = burn = realize
• ZRC-721 spec should preserve this yield-transferability-until-burn pattern from the 2022 deck

Historical Significance

• The Zoo Bridge (2022) predates most cross-chain bridges and was one of the earliest "play on any chain" NFT bridges
• The Zoo Jan 2022 "ZOO Bridge" and Oct 2021 "ETH-Binance Bridge" are the historical foundation for today's Zoo-Lux bridge protocol and omnichain teleport integration
