Token-pair launches.
Holder rewards, explained.
Launch coins with supported token pairs and follow their markets on sender. Learn how liquidity shapes trading, where fees go, and what can be verified about holder rewards.
How It Works
sender lets you launch a coin against a supported quote asset and follow its trading market. Choose the coin's identity and pair, then authorize creation with your wallet. Pump.fun's on-chain programs handle token creation and reserve-based trading. Pairing defines the asset used to trade the coin; it does not guarantee its value or give holders a right to redeem it for the quote asset.
Launch your coin
- Connect your wallet. Select a compatible Solana mainnet account. Connecting alone does not create a token or authorize a purchase.
- Choose the identity and pair. Enter a name, ticker and image. Verify the full mint address of the quote asset.
- Set an optional initial buy. Use the selected quote asset, or enter 0 to create without purchasing.
- Review, sign and confirm. Inspect the wallet request. sender lists the launch only after verifying successful confirmed execution.
Choose what the token trades against
A pair identifies the coin and the asset used to price and trade it. In TOKEN / USDC, TOKEN is the base token and USDC is the quote asset. Choose SOL, USDC, a listed stock or ETF-related token, or CUSTOM in the launch studio. sender checks the selected quote's compatibility before preparing the launch.
A market quoted in SOL
Pair your coin with SOL and use native SOL for an optional initial purchase. Keep enough SOL for transaction fees and account deposits. The studio displays the wrapped-SOL mint as the quote identifier.

Enter the full quote mint address. sender reads its available identity, decimals and token program, then checks whether the launch engine supports it. Compatibility is checked again during preparation, so a successful preview is not a guarantee that a later launch will succeed.
Pump.fun quote-asset referenceIdentity and metadata
Your coin's name, ticker, image and optional description form its public identity. sender uploads the image and metadata to IPFS and includes the metadata URI in the creation request. These details help people recognize a coin, but can be copied. Use the mint address to verify which token you are viewing.
| Field | Current requirement |
|---|---|
| Name | Required, up to 32 characters. |
| Ticker | Required, up to 10 characters; the studio uppercases typed input. |
| Image | Required: PNG, JPEG or WebP, up to 4 MB. |
| Description | Optional, up to 1,000 characters. |
| Website, X, Telegram | Optional HTTPS links, up to 300 characters each. |
Creation and the initial purchase
sender creates Token-2022 base mints through Pump.fun's create_v2 flow. If you select an initial purchase, it is included in the creation transaction. Creation and the purchase succeed together or revert together if execution fails. A failed transaction can still incur network fees.
Keep SOL for transaction fees and required account deposits even when buying with another quote asset. The current token-quoted initial-buy path uses a versioned transaction and a 1% slippage cap.
Pump.fun creation instructionsReview the wallet request
Check the creator account, token mint, quote asset and purchase amount. sender checks the signed message against the prepared launch before submission. Approval, submission and successful execution are separate events.
If confirmation takes longer
Keep the current browser session and use Check launch. sender saves the pending signed transaction in that session so you can check its outcome. Inspect the saved signature before launching again. Clearing session storage can remove the recovery record.
Solana transaction referenceHow the bonding curve prices trades
Trading changes the reserves that determine the curve's price. A buy adds quote assets and removes base tokens; a sell adds base tokens and removes quote assets. Virtual reserves are pricing inputs, while real reserves limit what the market can exchange. Fees and rounding also affect the amount received.
Bonding progress compares the curve's remaining real token reserve with its initial reserve, verified from the creation event. Selling can replenish reserves and reduce progress before completion. A completed curve reports 100%; otherwise, progress is unavailable when the required reserves cannot be verified. This percentage measures reserve depletion, not investment returns.
Input is 10% of the starting virtual quote reserve. Both reserves start at 100 illustrative units; the starting price is indexed to 1.
This normalized model has no graduation target. The live token must meet its quote-specific completion conditions and migrate. Moving this slider never changes a token’s actual bonding percentage.
Conceptual reserve quantities illustrate supply available to this model, not a token’s total minted supply. No amounts are denominated in SOL, USDC or another asset. Fees, rounding, actual reserve limits and migration are excluded.
Explore the mathematics
With starting base reserve x₀ and quote reserve y₀, the idealized model keeps x × y constant. The marginal price is y / x. A buy input r = Δy / y₀ gives p₁ / p₀ = (1 + r)². A sell input r = Δx / x₀ gives p₁ / p₀ = 1 / (1 + r)².
Average execution-price impact is |average price / starting price − 1|. This is distinct from the ending spot-price movement. Executable Pump.fun quotes require current state and the SDK’s actual integer calculations.
Completion and graduation are different states
Completion ends the curve phase, but migration may still be pending. sender labels a coin as graduated when both the curve's completion state and the SDK migration check confirm it. Completion conditions depend on the selected quote; the interface does not promise a universal market-cap threshold or time to graduation.
Liquidity and market data
Available reserves determine how much a market can exchange and how strongly a trade can move its price. Market cap and FDV describe valuation, not funds available for withdrawal. Liquidity can change, and market data may be delayed or unavailable. Graduation alone does not establish a liquidity lock or guarantee that you can sell.
Find a token and inspect its market
The market directory shows confirmed launches. Search by name, ticker or mint, filter by quote asset, and open a coin to review its pair, curve status and available market data. Verify the full mint when coins share a name or ticker.
Buy and sell through the paired market
Open the Pump.fun trading link on a sender token page to buy or sell. A buy exchanges the quote asset for the coin; a sell exchanges the coin for the quote asset. Review the destination market, fees and wallet request before approval. sender's embedded GeckoTerminal chart displays market activity and does not submit orders.
Price impact and slippage
Price impact is the change caused by your trade relative to available reserves. Slippage reflects the difference between expected and execution-time terms. Review both before trading: a displayed price or chart does not guarantee the amount your transaction will receive.
Fees
The launch transaction adds no separate fixed sender launch fee. Your costs can include an optional initial purchase, protocol trading fees, SOL network fees and account deposits. The trading fee allocation below belongs to Pump.fun; it is not a sender holder-reward allocation.
Protocol fee allocation
- Creator
- 0.30%
- Protocol
- 0.95%
- Liquidity provider
- 0%
Percentage of trade amount. Published Pump.fun schedule checked 9 November 2026. This example applies to SOL/USDC bonding curves, not every quote or graduated pool.
PumpSwap canonical pools use market-cap tiers for SOL/USDC; other quote assets follow different schedules. Fees are collected in the pool's quote asset, with routing-specific treatment for multi-pool trades. Rates can change.
Current Pump.fun fee schedule and collection rules| Cost | What to expect |
|---|---|
| Initial purchase | Optional; funded in the selected quote asset. |
| Network & accounts | SOL fees and required account deposits. Review the prepared transaction. |
| Fee collection | The sender interface has no fee-collection action. Check creator-fee entitlements and collection options through the relevant protocol tools. |
A processed transaction can incur network fees even when execution fails. No fixed all-in launch cost is promised.
Solana network feesHolder Rewards
Holder rewards require a configured distribution mechanism and verifiable payments. The current sender launch flow does not configure a holder-reward allocation, eligibility rules or payout schedule. Holding a coin launched through sender does not, by itself, establish a reward entitlement.
| Information | Current availability |
|---|---|
| Reward totals | Token pages show a holder-rewards panel, but the current token data does not supply payout totals or confirm an active reward program. |
| Distribution history | The panel has columns for cycle, amount and transaction. No distribution records or payment signatures are currently supplied. |
| Claiming rewards | The current interface has no holder-reward claim or distribution action. It cannot confirm a payout amount, asset or date for a holder. |
Creator fees and holder rewards are separate entitlements. The fee split above does not show that creator fees are redistributed to holders. Cashback is disabled in sender's launch builders, and the interface has no automated buyback or burn flow. No holder-reward percentage, payout frequency or yield is established by this implementation.
Tickers
Choose a ticker people can recognize, then use the full mint address to identify the coin. sender does not reserve symbols or grant exclusive rights to a ticker.
| Rule | Behavior |
|---|---|
| Required input | A non-empty symbol is required, up to 10 characters after trimming. |
| Letter case | The studio converts typed input to uppercase. |
| Duplicate symbols | There is no unique-ticker constraint or reservation check. Different mints can share a symbol. |
| Ticker charges | No separate ticker reservation, duplicate-symbol or premium-name fee is implemented. |
Do not infer authenticity from a familiar name, ticker or image. Compare the full mint in the launch result, wallet activity, explorer and intended trading market.
Risks
Launching or trading a coin can result in partial or total loss. A supported token pair does not guarantee demand, liquidity, rewards or future value. Confirmation means the launch transaction executed successfully; it is not an assessment of the coin's quality.
- Trading and liquidity
- Prices can move sharply. Thin reserves increase price impact, and displayed valuations do not guarantee an executable exit. Graduation does not guarantee lasting liquidity.
- Tokenized assets and issuers
- A stock-related quote is a separate token. Its backing, custody, redemption, transfer limits and eligibility depend on its issuer. It may lose its relationship to the referenced asset. Pairing a new token with it does not give the new token a claim on shares.
- Programs and infrastructure
- Smart-contract defects, authority changes, network disruption, RPC failures and third-party service outages can affect execution or access. Check the actual on-chain configuration.
- Identity and information
- Metadata can be copied. Market data, charts and images can be incomplete or stale. Verify base and quote mints independently.
Verify before signing
Inspect the requested accounts, assets and amounts in your wallet. Check the transaction's execution result on an explorer. Never enter a seed phrase into a token page or a support message.
Common questions
01Does connecting my wallet launch a token?
No. A launch requires a separate transaction approval and successful on-chain execution. Review the request before signing.
02Can I launch without an initial buy?
Yes. Enter 0 for the initial purchase. You still need SOL for transaction fees and required account deposits.
03Does choosing a stock quote make my new token a stock?
No. The quote is a separate blockchain asset used by the market. Verify its issuer and terms. A trading pair does not establish ownership of underlying shares.
04Does holding a sender-launched coin earn rewards?
Holding alone does not establish a reward entitlement. The current launch flow does not configure holder distributions, and the token page receives no reward totals or payment records. Verify any reported rewards against the token's rules and actual payment transactions.
05Can another token use the same ticker?
sender does not reserve tickers or enforce a unique symbol. Use the full mint address to identify a token.
06What should I do if a launch remains pending?
Keep the current browser session and use Check launch. Inspect the saved signature before attempting another launch. A returned signature alone does not prove successful execution.
