As a CTO working full-time in crypto since 2016, I’ve seen nearly every type of token launch: VCs, ICOs, IDOs/IEOs, airdrops, auctions, and more. But the bonding curve model, used by our platform to launch recently on #BelieveApp, is the closest we’ve come to pure, transparent, and fair distribution.
Here’s why — plus a curated list of the top bonding curve contracts actively used for launches on Solana. Whether you’re a builder or investor, this list gives you an essential edge in today’s market.
👇
What’s a bonding curve?
It’s a smart contract that defines price = f(supply). As more tokens are minted, the price increases algorithmically. No centralized control. No arbitrary valuation. This creates built-in price discovery — early buyers pay less, late buyers pay more. It’s fair, transparent, and immutable.
Compare that to a VC raise:
• VCs get 30% at $0.005
• Retail enters at $0.05
• VCs x10 before launch — before a single retail user touches the token
With bonding curves, everyone pays the same curve, based solely on when they enter — not who they know. This is market-driven capital formation without backroom deals.
Graduation and Liquidity
Tokens graduate once they hit a set threshold (e.g. $100K market cap). At that point, they exit the bonding curve and are paired into a real liquidity pool on a platform like @MeteoraAG.
How it works:
• Buyers mint via bonding curve
• Funds accumulate in the contract
• When the cap is hit → token “graduates”
• Contract auto-creates a LP: 50% SOL / 50% token
• LP is locked (usually permanently)
This means:
✅ Token now trades on a DEX with real liquidity
✅ LP can’t be rugged — it’s locked
✅ Early buyers have exit liquidity
✅ Open market sets the price from here
Graduation turns tokens into tradable markets — trustless, decentralized, no team needed.
Now let’s break down the top smart contracts and platforms that are bringing bonding curves and fair launch mechanics to life on Solana 👇
Dynamic Bonding Curve from Meteora
Meteora’s Dynamic Bonding Curve (DBC) is a fully on-chain, customizable bonding curve mechanism designed to help teams launch tokens with flexible, programmable liquidity.
Unlike fixed bonding curves, DBC allows projects to configure:
• Starting price
• Curve shape (linear, exponential, etc.)
• Max supply and price caps
• Slippage and fee parameters
Once deployed, the DBC contract manages token minting and pricing based on the defined curve. When a project hits its target, liquidity is migrated into a standard Meteora pool, handled automatically via DBC Migrator and Keeper contracts.
This ensures:
✅ Smooth handoff from bonding curve to DEX trading
✅ Custom price discovery aligned with project goals
✅ No manual LP creation or risk of mispricing
✅ Fully transparent on-chain configuration
This Dynamic Bonding Curve implementation is open source and available at: https://github.com/MeteoraAg/dynamic-bonding-curve
LaunchLab by Raydium
Raydium LaunchLab is a community-powered launch platform that combines simple bonding curves with Raydium’s AMM infrastructure — enabling anyone to launch a token, bootstrap liquidity, and go live on-chain in minutes.
It supports two modes:
• JustSendit — quick launch with default bonding curve settings
• LaunchLab — full customization of curve, supply, vesting, and fee structure
How it works:
• Buyers mint via bonding curve
• Once a SOL threshold is reached (default value is 85 SOL), the token graduates
• Liquidity is auto-migrated to a Raydium AMM pool
• LP tokens are burned or locked, ensuring long-term security
• Creators can optionally earn 10% of trading fees via a Fee Key NFT
LaunchLab also supports:
✅ Vesting for token supply
✅ Platform-branded launches
✅ Referral rewards for traders
✅ Permissionless deployment with no-code UI or full SDK access
It’s a fast, composable launch framework that turns memecoins, experiments, and serious projects into live markets — without CEXs or private rounds.

Gavel
Gavel.xyz is a powerful token distribution & liquidity bootstrapping protocol built for teams launching on Solana. Unlike raw bonding curves, Gavel’s system fights snipers and sandwich attacks while offering structured, capital-efficient token launches.
How it works:
• Teams launch via on-chain public sale (e.g. Dutch auction or fixed FCFS)
• Tokens are distributed proportionally to SOL contributed
• After the sale, Gavel auto-deploys sandwich-resistant liquidity
• LP is transient — it’s gradually withdrawn, swapped for tokens, and burned
This eliminates:
❌ Snipers draining early supply
❌ Sandwich bots exploiting DEX trades
❌ Locked LP waste or rugs
The result is fair, efficient price discovery + capital formation — no CEX, no MEV traps. Gavel is currently closed-access; teams can reach out via X @gavelxyz for onboarding.
Final Thoughts
Bonding curves unlock a new standard for token launches:
fair, transparent, and on-chain.
No VCs, no gatekeepers — just market-driven price discovery and liquidity.
If you’re building or investing in this cycle, understanding these mechanics isn’t optional — it’s alpha.
