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. |
