PiggyBank

A piggy bank wallet on Solana: save toward goals in SOL, USDC and USDT, swap between them and lock savings away from impulse buys.

PiggyBank is a piggy bank wallet on Solana. Set goals, save in SOL, USDC and USDT, and watch the jars fill up. Your keys stay with you. SAVE TOWARD GOALS • A trip, a new phone, a rainy-day fund: every goal gets its own jar. It fills with each top-up, and the piggy bank counts what’s left. • Goals are counted in dollars: USDC and USDT one to one, SOL at the current price. • Progress bars, confetti at 25, 50, 75 and 100%, and optional daily or weekly saving reminders. KEEP SAVINGS AWAY FROM IMPULSE BUYS • Lock until reached: the goal’s money can’t be taken out until you reach the amount. Then the lock comes off by itself. • Smart-contract lock: the money goes into a Jupiter Lock contract until the date you choose. There’s no protocol fee, and the storage deposit of about 0.005 SOL comes back when you take the money out. TOP-UPS, TRANSFERS AND SWAPS • A notification when money arrives, even with the piggy bank closed. Put it toward a goal right away. • Tiny spam transfers stay quiet and are marked in the history. • Swap SOL, USDC and USDT at the best rate Jupiter finds. The swap is simulated before signing, and only free money is swapped: what’s set aside stays put. • “Paste” understands Solana Pay links: the address, amount and token fill in by themselves. YOUR KEYS STAY YOURS • Non-custodial: your recovery phrase and private key are encrypted right in the browser (PBKDF2-SHA256 with 600,000 iterations, then AES-256-GCM) and never leave your device. • The piggy bank locks itself after 5 minutes, 15 minutes, an hour or 4 hours of inactivity — your choice. • Look-alike address guard: if a recipient only resembles an address you’ve used before, PiggyBank shows the difference and asks you to confirm. • No sign-up, no analytics, no trackers. A standard 12-word phrase, so the wallet opens in Phantom too. • Open source: the full code of the extension is public on GitHub under the MIT license, so anyone can check it: github.com/SolPiggyBank/piggybank FAIR FEES • Goals, top-ups, transfers and locks come with no PiggyBank fees. The Solana network usually charges less than a cent per transfer. • Swaps cost 0.7% of the amount (Phantom charges 0.85%), shown before you confirm. Works with free public Solana nodes right after you install it and picks the fastest one; you can add your own node in Settings. Available in English, Русский, Español, Français, Deutsch, Português, 简体中文 and 日本語, with light and dark themes.
