Overview
MintPad is an interface to public Solana programs. It reads Pump and PumpSwap activity straight from the chain, lets you inspect any token, and builds buy, sell and create transactions with Pump’s official TypeScript SDKs. Your wallet signs every transaction; MintPad never holds keys or funds.
Where the data comes from
- Scanner: recent signatures of the Pump program (
6EF8rrec…) and PumpSwap (pAMMBay6…), decoded into create, trade and graduation events. The window grows while the server runs; each list shows how many events and how much time it covers. - Token pages: live reads of the mint, its bonding-curve account and, after graduation, its PumpSwap pool. Price and chart come from recent trade events for that token.
- Holders: the largest token accounts from RPC. A total holder count needs an indexer (Helius DAS when
HELIUS_API_KEYis set).
When something isn’t available on chain, MintPad shows “—”. It never estimates missing values.
Metric definitions
- Price — quote per whole token from virtual reserves (curve) or pool reserves (PumpSwap).
- Market cap — price × total supply, in the quote currency (SOL or USDC).
- Reserves — real quote reserves held by the curve or pool.
- Volume (window) — sum of observed trades; the tooltip shows trade count and time span. 24h volume only appears when a provider has full 24h coverage.
- Bonding curve — share of the curve’s sellable supply already bought; 100% means graduated to PumpSwap.
- Trending — ranked by observed trade count and volume in the scan window.
Trading
Active curves trade through Pump’s bonding-curve instructions (SOL curves: buy/sell; token-quoted curves: buy_v2/sell_v2). Graduated coins trade on their canonical PumpSwap pool. MintPad simulates the transaction first, shows the fee and your slippage limit, then rebuilds it from fresh chain state when you confirm.
The slippage limit is encoded into the instruction and enforced by the program, not by the browser.
Launching
Launching uploads your image and a metadata JSON to the configured storage, then calls Pump’s create_v2, which creates a Token-2022 mint with Pump’s own metadata extensions. You can add an initial buy in the same transaction. A fresh mint keypair is generated in your browser, signs once, and is discarded.
Security
- MintPad never asks for a seed phrase or private key. Anyone who does is attempting theft.
- Every transaction requires explicit approval in your wallet. Check the network and amounts there.
- Token names, images and links come from untrusted metadata. Verify mint addresses before trading.
Risks
New tokens are extremely volatile and many go to zero. Prices can move between review and confirmation. Only trade what you can afford to lose. Nothing on MintPad is financial advice.
