Alt.fun vs Pump.fun Volume Bot: HyperEVM and Solana Compared

01The short answer

The right volume bot is decided by where your coin lives, not by which tool has the longest feature list. A coin launched on Alt.fun is an ERC-20 on HyperEVM whose price tracks a linked Hyperliquid perpetual futures contract, so it needs an engine that signs on HyperEVM, pays gas in HYPE and reads the perp before every fill. That is what the Alt.fun Volume Bot does. A coin launched on Pump.fun is a Solana token on a bonding curve, so it needs a Solana-native Pump.fun volume bot instead. For that side, we point operators to PumpWave.

The two launchpads look alike from a distance: both list new coins, both have a discovery feed, and both use a graduation step. Underneath, they differ in almost every mechanic that matters to a volume campaign - chain, price formula, gas, fee currency and what happens at graduation. The rest of this page walks through those differences so you can pick the right tool with confidence.

02How Alt.fun works

HyperEVM execution

Alt.fun is a token launchpad on HyperEVM, the EVM-compatible execution layer of the Hyperliquid Layer-1. Coins are standard ERC-20 contracts, wallets connect the way they would to any EVM chain (Chain ID 999), and gas is paid in HYPE. A volume engine for Alt.fun therefore behaves like any EVM tool: it signs transactions, pays HYPE gas and routes swaps through the Alt.fun router.

Perp-backed price

The unusual part is pricing. Every Alt.fun coin is linked to a Hyperliquid perpetual futures contract, typically a 3x or 5x leveraged version of an underlying such as HYPE, ETH, BTC or an index. The coin's price tracks that perp. As a result, swap volume on the spot pool does not move price the way it does on a bonding-curve launchpad; the peg holds it. Slippage is bounded by the perp peg rather than by depth alone, which is why this engine includes a perp-aware pause that waits out sharp perp moves before the next fill.

What volume does on Alt.fun

If volume cannot push price, its job is visibility. Continuous fills keep the trade tape under the chart active, qualify the coin for the Alt.fun Trending feed, advance the graduation progress bar and help third-party screeners that rank by 24-hour volume pick the coin up. Graduated coins keep the same perp-backed model, and the engine switches to the post-graduation router automatically, so a campaign does not have to change tools at graduation.

03How Pump.fun works

Solana bonding curve

Pump.fun launches tokens on Solana. A new token starts on a bonding curve: the launchpad's contract quotes every trade along a fixed formula, and each buy walks the price up the curve while each sell walks it down. There is no external pool depth on the curve; the formula itself is the counterparty. That makes buying and selling directly price-relevant in a way it is not on Alt.fun.

Graduation and migration

When enough demand completes the curve, the token graduates. The curve stops trading, the accumulated liquidity moves into an AMM pool, and the token gets a new pair address that aggregators begin to index. For a volume campaign this is a real change of venue: orders aimed at the curve have nowhere to go, and order sizes need to match pool depth instead of the curve formula. This is the biggest structural difference from Alt.fun, where graduation keeps the same pricing model.

What volume does on Pump.fun

On Pump.fun, volume shows up on the launchpad board, in the token's trade list and chart, and later on the aggregators that list the graduated pool. The board also has a social layer of comments and favorites, which is why Solana-side tools often pair trading flow with an engagement option. Visibility is the goal on both launchpads; the surfaces that reflect it are just different.

04Side-by-side comparison

The table below summarizes the launchpad mechanics and the volume tool we recommend for each. Figures for this site come from our own operator documentation; figures for PumpWave come from its published documentation.

05Fee, gas and tip models

On Alt.fun

Pricing here is one number: a flat 2% of the campaign volume you target, paid once in USDC on HyperEVM. That covers all HYPE gas for every fill, wallet generation, funding and rotation, RPC access, the wallet burn-down at the end and dashboard analytics. There are no subscriptions, tiers or per-wallet charges. The only gas your own wallet pays is the small amount of HYPE needed for the USDC payment transfer. The full breakdown sits in the pricing section of the docs.

On Pump.fun

Solana costs come in three parts: base transaction fees, priority fees that help a transaction land in a busy block, and Jito tips for bundles sent through a private relay. A Solana volume tool has to budget for all three across thousands of orders. According to PumpWave's published documentation, it folds those costs into one flat 1% of the configured target volume, which also covers sub-wallet funding and its comment and favorite layer, with a 100 SOL minimum target and the exact SOL amount shown before signing.

Why the headline percentages differ

The two fees are not directly comparable. One is denominated in USD and paid in USDC on HyperEVM; the other is a share of a SOL-denominated target paid on Solana. The networks have different cost structures, and the tools bundle different services. The useful comparison is the total quote for the campaign you actually plan to run on each chain, shown before you sign.

06Execution on each chain

Both tools aim for a tape that reads as many independent traders rather than one script, but they get there with chain-specific techniques.

On HyperEVM, this engine randomizes ticket sizes inside profile ranges, spaces fills with interval jitter and micro-pauses, rotates a fresh wallet pool every campaign and pauses when the linked perp dislocates beyond the configured threshold (default plus or minus 3%). Operators choose one of three profiles - Slow Build, Active Trending or Power Surge - and can override any setting in the dashboard.

On Solana, PumpWave's documentation describes orders submitted through Jito bundles over a private relay, with each buy and its paired sell landing together and bundle tips randomized. Sessions use new ephemeral wallets with randomized funding, a minimum block gap between related orders, regional RPC rotation and a fresh keypair per order. It runs in a browser console with no install, and the session can be paused, resumed or stopped at any time.

07Which tool per launchpad

Use this decision list before you fund anything:

1. Confirm the chain. Check the contract address on an explorer. A HyperEVM address belongs to Alt.fun; a Solana mint address belongs to Pump.fun.
2. Alt.fun coin on HyperEVM: use the Alt.fun Volume Bot. Pick a profile, set a volume target between $10,000 and $1,000,000, and pay once in USDC.
3. Pump.fun token still on the curve: use PumpWave, our recommended pick for Solana launches.
4. Pump.fun token close to graduation: choose a tool that follows the migration inside one session. PumpWave documents that its sessions re-point to the Raydium pool after graduation without a restart.
5. Coins on both launchpads: run two separate campaigns with two budgets. Do not try to bridge flow between chains.
6. Unsure about anything: ask before you pay. Our contact page covers the Alt.fun side.

If the Solana side is new to you, PumpWave's guide to choosing a pump fun volume bot covers session sizing, wallet counts and the graduation handoff in more depth than we do here. Our focus stays on Alt.fun and HyperEVM.

08Key takeaways

• Alt.fun coins are perp-backed ERC-20s on HyperEVM; Pump.fun tokens are Solana tokens on a bonding curve.
• Volume on Alt.fun builds visibility without pushing price; on Pump.fun, buying moves price along the curve and later the pool.
• Graduation keeps the same model on Alt.fun but changes the venue on Pump.fun, which is why migration handling matters on Solana.
• Compare total campaign quotes, not headline fee percentages, because the chains and fee currencies differ.
• Use the Alt.fun Volume Bot for Alt.fun and PumpWave for Pump.fun.

09Frequently asked questions

Can I use the Alt.fun Volume Bot on a Pump.fun token?

No. The Alt.fun Volume Bot runs natively on HyperEVM, signs every swap there, pays gas in HYPE and routes through the Alt.fun router. Pump.fun tokens live on Solana, which needs a Solana-native tool. For Pump.fun we recommend PumpWave.

Why does buying move price on Pump.fun but not on Alt.fun?

A Pump.fun token starts on a bonding curve, so each buy walks the price up the curve. An Alt.fun coin is linked to a Hyperliquid perpetual futures contract and its price tracks that perp, so spot swap volume fills the trade tape and drives discovery without pushing price on its own.

How do the fees compare?

This site charges a flat 2% of the campaign volume you target, paid once in USDC on HyperEVM, covering HYPE gas, wallet rotation, RPC access and wallet burn-down. According to PumpWave's published documentation, it charges one flat 1% of the configured target volume on Solana, covering base fees, priority fees, Jito tips and sub-wallet funding, with a 100 SOL minimum target. The two are denominated and structured differently, so compare the total quote for your own campaign rather than the headline percentage.

What happens to a volume campaign when the coin graduates?

On Alt.fun, graduated coins keep the same perp-backed model and the engine switches to the post-graduation router automatically. On Pump.fun, graduation moves liquidity off the bonding curve into a pool; PumpWave documents that its sessions follow that migration block by block and re-point to the Raydium pool inside the same session.

Does either tool guarantee a trending position?

No. Volume improves visibility on each launchpad's discovery surfaces, but trending placement depends on each platform's own ranking and on what other coins are doing at the same time. Neither tool promises a rank or a price.
