Wallet Spring Cleaning for Solana Mobile — Reclaim SOL from empty token accounts
Every token account on Solana costs ~0.002 SOL in rent. If you've airdropped, swapped, or experimented with tokens, your wallet likely has dozens of empty accounts holding your SOL hostage.
RentQuest scans your wallet, identifies reclaimable accounts, and batch-closes them — returning your SOL with satisfying animations and achievement unlocks.
Token Account A: 0 USDC → 0.00203928 SOL locked
Token Account B: 0 BONK → 0.00203928 SOL locked
Token Account C: 0 JUP → 0.00203928 SOL locked
... × 50 accounts = 0.10+ SOL lost!
RentQuest makes wallet cleanup:
- Safe — Only closes zero-balance accounts you own
- Fast — Batches up to 8 closures per transaction
- Fun — Gamified with achievements and animations

# Clone the repository
git clone https://github.com/your-org/RentQuest.git
cd RentQuest
# Build debug APK
./gradlew assembleDebug
# Install on connected device
./gradlew installDebug
# Run tests
./gradlew test- Open app → Settings → Switch to Devnet
- Get Devnet SOL from a faucet
- Create test token accounts
- Scan and close!
The app uses strict safety checks before closing any account:
fun isClosable(account: TokenAccount): Boolean {
// ✅ Amount must be exactly zero
if (account.amount != 0L) return false
// ✅ User must be the owner
if (account.owner != connectedWallet) return false
// ✅ No close authority restrictions
if (account.closeAuthority != null &&
account.closeAuthority != account.owner) return false
return true
}- All transactions signed locally via Mobile Wallet Adapter
- No private keys ever leave the wallet app
- Each transaction is individually confirmed on-chain
