A lof ot innovations:

Creative Idea Highlights

Track Idea Why it’s exciting
Wallet UX "Instant‑Upgrade Wallet" – Click once, your MetaMask EOA temporarily becomes a smart account with social‑recovery & 2FA for the next N txs. No new wallet install, onboarding in seconds.
Wallet UX Subscription Signer – Grant Spotify‑style dApp a weekly 5 USDC spending cap via 7702 session key. Fine‑grained allowances without a new contract wallet.
DeFi / Payments One‑shot Leverage – Bundle borrow → swap → LP add into a single 7702 tx, saving gas & slippage. Show tangible UX win vs multi‑sig clicks.
Payments Gasless Airdrops – Project sponsors the 7702 tx, users claim tokens with zero ETH balance. Perfect newbie on‑ramp.
Security Guardian Rescue – Lost phone? Guardians co‑sign a 7702 tx that rotates your root key. Familiar social‑recovery with no contract wallet lock‑in.
Gaming Burner Keys for Quests – Game mints a temp sub‑key valid only inside the game world. Protects main wallet assets.
NFT / Creator Sponsored Mint‑&‑List – Artists airdrop gas‑paid mint + OpenSea listing in one signed blob. Friction‑free launches.
Tools 7702 Dashboard, Revoke tool, Security Tool, etc.
