Extreme volatility
Memecoins are speculative assets with no intrinsic value. Prices can drop 90%+ within hours of launch. Never invest more than you can afford to lose entirely.
SunPump
SunPump is TRON’s premier fair-launch platform for memecoins, utilizing an automated bonding curve to eliminate pre-sales and team allocations. Part of the Sun.io ecosystem, it ensures permanent liquidity and prevents common rug-pull vectors, providing a transparent launchpad for all community-driven tokens.

Core Concepts
Section titled “Core Concepts”The Bonding Curve
Section titled “The Bonding Curve”SunPump uses a bonding curve — a mathematical pricing formula embedded in a smart contract — to determine token prices in real time. Unlike a traditional DEX where liquidity must be seeded by the creator, the bonding curve itself acts as the market maker from the moment of creation.
- Price increases as more tokens are purchased (supply is consumed along the curve)
- Price decreases as tokens are sold back into the curve
- There is no order book — every buy and sell executes against the smart contract at the algorithmically determined price
- The curve is deterministic and transparent — anyone can calculate the price at any point on the curve
Fair Launch Mechanics
Section titled “Fair Launch Mechanics”Every SunPump launch enforces the same rules:
| Rule | Enforcement |
|---|---|
| No pre-sale | The bonding curve opens simultaneously for all participants |
| No team allocation | 100% of the token supply enters the bonding curve |
| Immutable supply | Total supply is fixed at creation — no minting function |
| Equal access | The creator has no privileged access — they buy on the same curve as everyone else |
This does not eliminate speculation or loss — it eliminates specific rug-pull mechanics (hidden mints, pre-sale dumps, creator-controlled liquidity).
How a Token Launch Works
Section titled “How a Token Launch Works”- Token Creation. A creator sets the token name, ticker, description, and image. They pay a small creation fee (~20 TRX). The smart contract deploys with a fixed supply and opens the bonding curve immediately.
- Bonding Curve Trading. Users buy and sell the token directly through the bonding curve contract on sunpump.meme. A 1% trading fee is charged on each transaction during this phase. The price rises as more TRX flows in and falls as tokens are sold back.
- Bonding Curve Completion. When the bonding curve reaches 100% of its capacity (approximately 100,000 TRX accumulated), the seeding process begins automatically. This is an irreversible smart contract action — no human intervention is required.
- Liquidity Seeding. The smart contract deposits ~100,000 TRX alongside the remaining 200 million tokens into a SunSwap V2 liquidity pool. A liquidity addition fee of approximately 3,000 TRX is deducted from the accumulated funds. The LP tokens created by this deposit are burned — making the liquidity permanent and irremovable.
- Open Market Trading. After seeding, the token trades on SunSwap like any other TRC-20 token. The bonding curve contract is no longer active — all trading occurs through the SunSwap AMM pool.
Buyback and Burn
Section titled “Buyback and Burn”In September 2024, the SunPump team transitioned from burning LP tokens to a 100% on-chain buyback and burn mechanism for the SUN token:
- Platform revenue (trading fees collected during the bonding curve phase) is used to buy SUN on the open market
- Purchased SUN tokens are permanently burned (sent to a dead address)
- All buyback-and-burn transactions are verifiable on-chain via TRONSCAN
This creates a deflationary pressure on the SUN token supply, directly linking SunPump’s trading volume to the broader Sun ecosystem’s tokenomics.
Key Parameters
Section titled “Key Parameters”| Parameter | Value |
|---|---|
| Token creation fee | ~20 TRX |
| Bonding curve trading fee | 1% per transaction |
| Bonding curve completion | ~100,000 TRX accumulated (100% of curve) |
| Liquidity seeding | ~100,000 TRX + 200M remaining tokens → SunSwap V2 |
| Liquidity addition fee | ~3,000 TRX (deducted from bonding curve funds) |
| LP token handling | Burned (permanently locked liquidity) |
| Revenue model | 100% buyback and burn of SUN token |
Risk Considerations
Section titled “Risk Considerations”Most tokens never complete the curve
The vast majority of SunPump tokens never reach 100% of the bonding curve. If a token fails to complete, your purchased tokens may become effectively worthless as trading activity dries up.
Sniper bots and front-running
Automated bots monitor SunPump for new launches and buy within the first seconds, securing tokens at the lowest bonding curve prices. By the time most users see a new token, bots may already hold significant positions and will sell into your buy pressure.
Social manipulation
Memecoin communities frequently use coordinated social media campaigns to drive buying pressure. The creators of these campaigns often sell their positions at the peak. DYOR — do not buy based on hype alone.
