A lof ot innovations:
| 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. |
