Coinbase is rolling out prediction markets and tokenized stocks as part of its December product push, which will make event betting and fractional equity exposure available to a much larger retail audience.  This changes the risk surface for everyone in the Base and Farcaster ecosystem. size positions carefully, avoid leverage when markets are rumor driven, and treat new tokenized products as regulated derivatives until proven otherwise. Builders should design clear settlement trails and custody options so user funds and expectations do not diverge.

ERC-6551 is turning NFTs into autonomous, programmable accounts so a single NFT can hold tokens, other NFTs, and interact with contracts as if it were a mini wallet. Adoption across EVM chains is picking up and that means collectibles and game characters can start carrying their own balance and permissions onchain.  Think of token bound accounts as a product decision not a gimmick. keep user recovery and key rotation simple, avoid storing large sums inside a TBA by default, and expose clear UX so owners always know what assets move with a sold NFT.

NFT renting is becoming a real market move in 2025 as protocols and standards make temporary ownership practical for games, drops, and airdrop access. This trend lowers the barrier for people who want to use rare assets without full custody and creates new utility layers on top of collections.  If you plan to build or participate, treat rentals like product design not speculation. keep rental flows simple, add clear expiry and reclaim logic, and test escrow and delegation flows thoroughly so users get utility without unexpected custody risk.
