📡 Small Data Stream update

We added postBalances to all events. It shows the SOL balances of accounts involved in the transaction.

Included:
• the txSigner
• all tradersInvolved
• for SOL transfers — both the sender and the receiver

⚠️ For token transfers, only the sender's SOL balance is included. The SOL balance of the account that received the tokens is not shown.

📡 Data stream update

All events now include a priorityFee field.

This is useful for gauging how important a transaction is to the trader who sent it — the higher the priorityFee, the more the trader cared about landing it.

P.S. We also updated the migration docs (https://pumpapi.io/migrate-pump-fun/) — migrating tokens from pump.fun and buying them immediately is now even easier with Jito Bundles.

🎞 Historical Replay Is Live! 🎞

Starting from April 18, we save every single event from our Data Stream — every hour.

Perfect for backtesting strategies, research, replay simulations, or anything else you can think of.

⚡️ Fast by design
• ~400 MB per hour (zst-compressed, 2 GB decompressed)
• ~1 second to decompress 1 file
• Same format as the live stream


🧩 Dead simple to use
Just copy the replay snippet from the docs and run it. You can also browse every saved file like folders — for example, replay.pumpapi.io/2026/04/ shows every hour we saved for April.

💸 Price? FREE!
just download and replay.

Jito Bundles in lightning mode now also return bundle UUIDs (..."bundleUUIDs": ["bundle_uuid"]), so you can track why your transaction didn’t land on explorer.jito.wtf.

Jito Bundles include an internal preflight simulation, so if a transaction fails (for example, due to low slippage), you’ll see that the transaction doesn’t exist. With regular transactions, you would see the failure reason and still be charged a priority fee, whereas Jito doesn’t charge anything if the transaction fails.

We also fixed “migrate.” If you previously tried token migrations and it didn’t work — it works now.

🚀 BEAST MODE! 🚀

• Data Stream — 100 ms faster
• Trade API — 200 ms faster
• Landing rate — 100%🔥

🌍We moved our servers to Frankfurt
Why? 68% of all Solana validators are located in Europe

If your server is in the US — SWITCH TO FRANKFURT. Otherwise you won't unlock the full potential of PumpApi

🛠 Trade API & Data Stream update

1. Trade API — full execution control

We've added new parameters:
- maxQuoteAmountIn, minBaseAmountOut — for buys
- maxBaseAmountIn, minQuoteAmountOut — for sells

Slippage alone doesn't give you full control — the price can shift several times within milliseconds. By passing these parameters you fully control your transaction's execution and will never buy at a price you didn't expect.

2. Data Stream — quoteMint everywhere

Soon pump.fun is rolling out support for creating and trading tokens with quoteMint = USDC. To prepare you for this, we now include the quoteMint field for WSOL pools too (previously we only sent it for pools where the quote token wasn't SOL).

📍 Reminder: our servers moved to Frankfurt to sit next to the validators. Move your servers to Frankfurt for a significant speed boost.

Breaking changes — June 10 ‼️‼️

pump.fun added USDC as a quote token. We're renaming a few fields so you don't have to handle SOL and USDC separately in your code:

solAmount → quoteAmount
solInPool → quoteInPool
vSolInBondingCurve → vQuoteInBondingCurve
marketCapSol → marketCapQuote
txType → action (one tx can produce multiple events, so "tx type" was misleading)

Until June 10 both old and new names are sent in every message. After that, only the new names remain. Switch your code now.

Creating USDC-quoted tokens

You can now create pump.fun tokens with a custom quote. To launch a USDC-quoted token, pass:

'quoteMint': 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v'

Trading USDC-quoted tokens

You must pass the same quoteMint on every buy/sell. Without it, quoteMint defaults to WSOL — you'll either get an error, or — worse — hit a scam pool with the same base mint.

When you trade, we pick the best pool for the mint + quoteMint pair. Wrong quoteMint = wrong pool.

🚀 2 huge updates!

1. postBalances now include final token balances for tokens involved in the event (signer + tradersInvolved in trades, sender + receiver in transfers) — not just SOL.

2. Every trade event now includes: name, symbol, uri, supply.

You asked us for this a lot — and we finally shipped it. Super useful for everyone building their own dashboards. 📊

Trade API update ⚡️

1. Smarter pool selection 🎯
By default we now pick the best pool across all pools available for the token — not just the mint-quoteMint pair.

For example, if the best pool uses USDC, you'll spend/receive USDC. Want to limit selection to a specific pair? Just pass quoteMint like before. Now you can sell every token in a wallet without checking which pools they trade in — the quote token is resolved automatically.

2. New "trades" array in every response 📊
Each buy/sell via the Lightning API now returns:

'trades': [{'poolId': '...', 'mint': '...', 'quoteMint': '...', 'pool': 'amm-name'}]

✔️So you can see exactly which pool was used and which quoteMint was spent/received.

📲Data stream update📲

We added two new fields to every event we send:

• programsUsed — addresses of programs that triggered the event, such as Jupiter, Axiom, and others.
• addressLookupTables — a list of ALTs used to include more accounts in the transaction.

Reminder: Pump AMM will release an update on June 20 that changes how prices are calculated. You don’t need to change anything.
If you currently calculate prices yourself, please switch to using the price field included in every event.
