Token Tails

Final Deliverable: Catnip Heist + multiple extras across existing Token Tails ecosystem

• ShelterSplit on Arbitrum Sepolia. A registry in the contract holds each shelter's wallet, name and share in basis points. disburse(amount, memo) pulls Circle USDC and pays every active shelter its share in one transaction; donate(memo) does the same for ETH. Low fees on Arbitrum make small, frequent gifts worth sending.

• DonateRouter on Arbitrum Sepolia: a giver signs one EIP-3009 USDC authorization and the router forwards it into ShelterSplit in the same transaction, after checking the split pays only registered shelters. No approval step, nothing parked in the router.

• Catnip Heist (https://tokentails.com/heist): after a win the player taps "Send Pink Paw a rescue treat" and Token Tails pays a small treat from a capped daily budget (signed in, verified email, once a day). The player picks the network the treat lands on, Arbitrum included, and gets a receipt page and a share card.

• The payouts page (https://tokentails.com/shelter-payouts) reads every payout from chain events, with explorer and receipt links. No backend is trusted for the numbers.

• ShelterSplit Rail: an open MIT SDK and a one-tag donate widget, so any app or AI agent can pay the same shelters. Players never need a wallet: purchases stay card or in-app. Givers who have one can give from it.
