What Is LetsBonk? The Bonk-Backed Solana Launchpad Explained

For one wild stretch of summer 2025, the busiest memecoin factory on Solana wasn't Pump.fun — it was LetsBonk. On a single Sunday in July it minted nearly twice as many tokens as Pump.fun and grabbed the majority of new-launch market share. The dominance didn't last, but the platform did, and it sits on a clever twist: every trade quietly buys back and burns BONK. If you trade Solana memecoins, you'll route through LetsBonk graduates whether you mean to or not. Here's exactly what it is, how launches work, where the fees go, and what actually matters for traders in 2026.

What LetsBonk actually is

LetsBonk (the site is letsbonk.fun, also branded Bonk.fun) is a no-code Solana memecoin launchpad. You connect a wallet, type in a token name, ticker, image, description and socials, and deploy a tradable token on a bonding curve in under a minute — the same launch-in-one-click pattern that Pump.fun popularized. It launched on April 25, 2025, roughly a week after Raydium unveiled its LaunchLab product, and it was built by the BONK community as the ecosystem's flagship product.

The defining twist — the thing that separates LetsBonk from every other launchpad — is where the money goes. Platform fees feed directly back into the BONK token through buyback-and-burn. Every swap on the platform quietly funds purchases of BONK on the open market, which are then burned. That's the "flywheel" BONK holders talk about, and it's the reason the launchpad exists at all. For the wider field of launchpads it competes with, see Solana launchpads compared.

The Raydium and LaunchLab connection

LetsBonk isn't a standalone stack built from scratch. It's built on Raydium's LaunchLab framework — multiple sources describe it as a third-party launch platform developed by the BONK team on top of LaunchLab, leaning on Raydium's liquidity infrastructure. Reportedly Raydium de-emphasized promoting LaunchLab under its own brand and backed the BONK team behind the scenes instead.

That arrangement made Raydium one of the biggest beneficiaries. LaunchLab's own 1% issuance fee directs a slice to RAY buybacks (Odaily cites roughly 25% to RAY repurchases for the underlying framework), and at one point LaunchLab launch fees became Raydium's single largest revenue source. By some estimates LetsBonk accounted for the overwhelming majority of LaunchLab volume in Q3 2025 — reportedly around 96% ($12.3M of $12.8M), though that's a single secondary figure, so treat the precise split as unconfirmed. The practical point stands: LetsBonk and Raydium are deeply intertwined, and graduated LetsBonk tokens end up in Raydium pools.

How a launch works, step by step

The mechanics will feel familiar if you've read how bonding curves and graduation work on other launchpads:

1. Create. Fill in the token details, deploy. The token starts life on a bonding curve — a formula where the price rises automatically as people buy and falls as they sell. No pre-seeded liquidity pool, no listing application.
2. Trade on the curve. Early buyers transact directly against the curve. This is the highest-risk phase: thin, fast, and the stage where most tokens live and die.
3. Graduate. When the curve fills — enough SOL is raised — the token "graduates" and migrates to a Raydium AMM liquidity pool for open DEX trading. At migration, liquidity is reported to be permanently locked or burned, which is a meaningful (but not total) reduction in rug risk.

The graduation threshold is reported inconsistently across sources and appears to have shifted over time. It's commonly cited at roughly a $69K–$70K market cap; one November 2025 figure put it around 411 SOL (~$58,300); and the underlying LaunchLab framework has been cited at 85 SOL of raised liquidity. Because the curve is denominated in SOL, the dollar figure drifts with SOL's price anyway — treat the exact number as a moving target, not a constant.

One number that's consistent across the board: graduation is rare. Only about 0.9%–1.2% of launched tokens ever fill their curve and reach Raydium. The vast majority never make it — the same brutal funnel you see on every launchpad.

The 1% fee and the BONK burn

LetsBonk charges a flat 1% trading/swap fee, plus a small cut of ongoing volume after migration rather than a flat listing fee. The interesting part is where that 1% is split. The most consistently reported breakdown is:

• ~40% to platform development.
• ~30% to BONKsol validator support.
• ~30% to BONK buyback-and-burn.

Be aware the buyback share is the figure sources disagree on most — some secondary outlets phrase it as 50%, and DeFiLlama frames it as "58% to holders and protocol." Those conflict, so treat the exact percentage as unconfirmed; 30% is simply the most commonly cited. Either way, the mechanism is the same: a portion of every fee buys BONK on the open market and permanently burns it, creating deflationary pressure for holders. That's the "BONK-backed" part of the pitch — the launchpad's volume directly reduces the BONK supply.

A 1% swap fee is the platform's cut. It sits on top of Solana network fees, priority fees, the DEX/AMM fee, and any trading-bot fee you're paying. If you want the full stack broken down, read what Solana trading bot fees actually cost so the headline number doesn't surprise you at settlement.

The July 2025 rise — when it flipped Pump.fun

LetsBonk's breakout was real and well-documented. On Sunday, July 6, 2025, it flipped Pump.fun in daily tokens created — ~19,620 vs Pump.fun's ~9,249, taking roughly 58.5% market share of new launches and pushing Pump.fun into the minority for the day. That wasn't a one-day fluke: it peaked in July at well over 78% of Solana launchpad share, with some trackers citing 80–84%.

Other peak figures reported around that window — a roughly $539M single-day volume on July 7 and over $1M in peak daily fees — came from secondary outlets rather than an on-chain dashboard verified here, so anchor on the directional story rather than the exact dollars. On July 18, 2025 it reportedly set a record of about 26,600 tokens launched in a single day. For a few weeks, LetsBonk genuinely was the center of gravity for Solana memecoin launches.

…and the fall back to Pump.fun

The dominance was short-lived. By mid-August 2025 activity collapsed and Pump.fun retook the lead — reported at around 73.6% share the week of August 11–17, with some trackers showing LetsBonk falling to roughly 3% by August 18. Pump.fun's recovery is widely attributed to its aggressive PUMP-token buybacks and trading incentives. By September 2025, Pump.fun was reported back around 81% share.

The lesson for traders isn't "LetsBonk died" — it didn't. It's that launchpad leadership on Solana is volatile and incentive-driven. Share swings on token buybacks, fee rebates, and where the creators-and-snipers crowd smells the next wave. Don't treat any single launchpad's dominance as permanent.

Where LetsBonk stands in 2026

The most concrete recent data point: KuCoin reported a ~600%+ revenue surge in the first week of January 2026, with single-day fees peaking at $352,793 and "millions" in BONK buybacks over that stretch. So the platform was very much alive and generating real fees going into 2026.

A clean, current (May–June 2026) market-share split between LetsBonk and Pump.fun wasn't cleanly reported in the sources available, so treat any precise "X% vs Y%" claim for right now with skepticism. The durable takeaway is that the two trade leadership in a back-and-forth, with Pump.fun generally holding the larger lifetime revenue base (reported at $800M+). LetsBonk is best understood as the strong, BONK-backed challenger that periodically surges rather than a permanent number one or a has-been.

What LetsBonk means for how you trade

• You'll find LetsBonk tokens everywhere. Use letsbonk.fun directly (it has new and about-to-graduate filters), or spot them through the usual Solana aggregators and scanners — DexScreener, GMGN, Photon and the early-discovery tools. Graduated tokens live in Raydium pools and route through Jupiter, so any decent bot reaches them automatically.
• "Locked liquidity" reduces, not eliminates, rug risk. Liquidity being burned at graduation removes the classic pull-the-liquidity rug, but it doesn't stop honeypots, malicious mint or freeze authority, or a dev dumping their pre-bought bag. Run the due-diligence checklist regardless of which launchpad a token came from, and know the anatomy of a rug pull.
• Pre-graduation is the danger zone. Tokens still on the bonding curve carry the highest risk — thinnest liquidity, no locked pool yet, and roughly 99% of them never graduate. One point-in-time Dune analysis suggested a higher share of LetsBonk launches looked "legitimate" (~70%) versus Pump.fun (~22%) around the flip, but that's a single dashboard snapshot, not a standing guarantee — don't let it lower your guard.
• The risk profile is still extreme memecoin risk. The vast majority never graduate, most go to zero, and rugs and honeypots remain common. A working exit strategy and strict position sizing matter more than picking the "right" launchpad.

How MoonHydra handles LetsBonk tokens

MoonHydra routes buys and sells through Jupiter, so LetsBonk graduates sitting in Raydium pools are part of the routing automatically — you paste a contract address and the bot finds the liquidity without you choosing a venue. The flat 1% per trade is the only fee MoonHydra adds on top of network and DEX fees; there's no separate listing or migration step on our side. Optional RugCheck screens a token's mint/freeze authority and LP before a buy, which is exactly the kind of guardrail you want on a freshly graduated launchpad token. You can snipe the graduation moment, set TP/SL or limit orders on a position, and run separate Hydra Head wallets for sniping versus holding — all from Telegram, all non-custodial, with exportable AES-256-GCM-encrypted keys.

Bottom line

LetsBonk (Bonk.fun) is the BONK community's no-code Solana launchpad, built on Raydium's LaunchLab and launched in April 2025. Its signature feature is the 1% fee that — by the most commonly cited split — sends roughly 30% into buying and burning BONK, turning launchpad volume into deflationary pressure for the token. It genuinely flipped Pump.fun in July 2025 before Pump.fun's buyback war pulled leadership back, and the two have traded the lead in a volatile back-and-forth ever since. For a trader, the launchpad a token came from matters far less than the fundamentals: graduation is rare (~1%), locked liquidity cuts but doesn't kill rug risk, and the pre-graduation curve is where most money goes to die. Treat every exact figure here as a moving target, and do your own due diligence before you buy.
