Tap the pig to drop a coin

Works on Solana with SOL USDC USDT Swap between them right in the piggy bank

Three steps to your first goal

Setup takes a couple of minutes. After that the piggy bank tells you how much to put aside.

  1. 1

    Create your piggy bank

    Pick a password and write down your 12-word recovery phrase. Already have a Solana wallet? Import it with the phrase or a private key.

  2. 2

    Top it up

    Send SOL, USDC or USDT to your piggy bank address or QR code, from an exchange or another wallet. You’ll get a notification when it arrives.

  3. 3

    Save toward goals

    A trip, a 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.

Swaps right in the piggy bank

Swap SOL, USDC and USDT in a couple of taps at the best rate Jupiter can find. No need to move money to an exchange and back.

  • The best rateJupiter searches every exchange on Solana for it.
  • A 0.7% fee — lower than Phantom’sPhantom charges 0.85%. You see the fee, the rate and the minimum you’ll get before you confirm.
  • Checked before signingThe piggy bank simulates the swap first and signs only if exactly the amount shown leaves.
  • Goals stay putOnly free money is swapped; what’s set aside stays where it is.

With a month or less to go, the piggy bank switches to a daily amount — easier to keep up.

Two levels of protection from impulse spending

Choose for each goal how tightly the money is locked.

Locked until reached

Lock until reached

Until the goal is reached, its money can’t be taken out, and the goal can’t be deleted or unlocked — no word or button gets around it. The lock comes off by itself once you reach the amount.

The money goes into a Jupiter Lock smart contract until the date you choose. There’s no way to take it out early — not here, not with another wallet, not through support.

  • The piggy bank locks itself after inactivity: after 5 minutes, 15 minutes, an hour or 4 hours — your choice.
  • Before every transfer it checks the address and the recipient’s token account and shows the network fee.
  • The extension talks only to Solana network nodes, a SOL price service and, for swaps, Jupiter.

Questions and answers

Is it free?

Yes: goals, top-ups, transfers and locks come with no PiggyBank fees. The Solana network usually charges less than a cent per transfer. Only token swaps cost something: 0.7% of the amount (Phantom charges 0.85%), shown before you confirm.

Do I need Phantom or another wallet?

No, PiggyBank is a wallet on its own. If you already have a Solana wallet, you can import it with its recovery phrase or private key.

Where is my money kept?

On the Solana blockchain, at your address. Goals are markers inside the piggy bank: money in a regular goal stays in your wallet, and money in a smart-contract goal sits in a Jupiter Lock contract until the date.

Can I take money out early?

From a regular goal, any time. From a protected one, not until it’s reached — on purpose, so the savings don’t go on an impulse buy. From a smart contract, not either: the money unlocks on the date you chose. The money still stays in your own wallet — the recovery phrase opens it in any Solana wallet.

What if I forget my password?

The password can’t be recovered, but the wallet can: remove it from the extension and import your recovery phrase again. The money is safe; you’ll need to set up your goals again.

How much does a smart-contract lock cost?

There’s no protocol fee. The network holds a storage deposit of about 0.005 SOL plus a small transaction fee. The deposit comes back when you take the money out.

Which coins are supported?

SOL, USDC and USDT on Solana. Goals are counted in dollars: USDC and USDT one to one, SOL at the current price.

Is PiggyBank open source?

Yes. The extension’s full code is on GitHub under the MIT license. Anyone can read how keys are encrypted, which addresses the extension talks to and how swaps are checked before signing.
