Some folks in the Hummingbot community are discussing how to apply bots to NFTs on the Commonwealth forum.
Also, the Block recently published an article about GSR exploring NFT algo trading.
As described in the DappRadar article about DeFi Kingdoms:
The DeFi Kingdoms platform is, by this stage, building out a dapp with a real utility on Harmony. Users could jump in, and DeFi Kingdoms offered token swaps, an in-game NFT marketplace, yield farming, and staking. All wrapped up in a user-friendly UX.
This could be an interesting research area for ONE Liquidity DAO to explore, since the Hummingbot connector should enable any automated strategy facing any Harmony project.
