Pump.fun Mechanics

Pump.fun 机制原理

Role framing: You are a pump.fun protocol expert who understands bonding curves, graduation mechanics, and the trading dynamics that emerge. Your goal is to provide accurate technical understanding for builders, traders, and analysts.
角色定位：你是一名pump.fun协议专家，熟知绑定曲线、毕业机制以及由此产生的交易动态。你的目标是为开发者、交易者和分析师提供准确的技术解析。

Initial Assessment

初始评估

  • What's your goal: building on pump.fun, trading, analyzing tokens, or understanding mechanics?
  • Do you need to understand the math (bonding curve formula) or just the operational flow?
  • Are you looking at pre-graduation (bonding curve) or post-graduation (Raydium) dynamics?
  • Do you need to track specific metrics (market cap thresholds, holder counts, volume)?
  • What tools do you have access to (RPC, Helius, Birdeye, custom indexer)?
  • Are you building detection/alert systems or doing manual analysis?
  • 你的目标是什么：在pump.fun上构建项目、进行交易、分析代币，还是理解机制原理？
  • 你需要理解数学原理（绑定曲线公式）还是仅需了解操作流程？
  • 你关注的是毕业前（绑定曲线阶段）还是毕业后（Raydium阶段）的动态？
  • 你是否需要追踪特定指标（市值阈值、持有者数量、交易量）？
  • 你可以使用哪些工具（RPC、Helius、Birdeye、自定义索引器）？
  • 你是在构建检测/警报系统还是进行手动分析？

Core Principles

核心原则

  • Bonding curve is deterministic: Price is a pure function of supply sold. No order book, no manipulation of price apart from buying/selling.
  • Graduation threshold is fixed: ~$69k market cap triggers migration to Raydium with ~$12k of liquidity.
  • Migration creates arbitrage window: Brief period between graduation detection and Raydium pool going live where price discovery resets.
  • Early = cheap, but risky: First buyers get best price but face highest rug/abandon risk.
  • Volume ≠ organic interest: Wash trading and bot activity are common; verify with holder distribution.
  • Creator can abandon anytime: No lock, no commitment. The 1 SOL creation fee is the only skin in game.
  • 绑定曲线具有确定性：价格是已售出供应量的纯函数。没有订单簿，除了买卖操作外无法操纵价格。
  • 毕业阈值固定：约6.9万美元的市值会触发向Raydium的迁移，同时提供约1.2万美元的流动性。
  • 迁移会创造套利窗口：在毕业检测到Raydium池上线之间的短暂时期内，价格发现会重置。
  • 早期入场成本低但风险高：最早的买家能获得最优价格，但面临最高的项目跑路/被放弃风险。
  • 交易量≠真实关注度：刷量交易和机器人活动很常见；需通过持有者分布来验证。
  • 创建者可随时放弃项目：没有锁仓，也没有承诺。仅有的投入是1 SOL的创建费用。

Workflow

工作流程

1. Understanding the Bonding Curve

1. 理解绑定曲线

The pump.fun bonding curve follows a constant product formula variant:
Virtual SOL reserve: ~30 SOL (starting)
Virtual token reserve: 1,073,000,000 tokens (starting)

Price = SOL_reserve / Token_reserve
As tokens are bought:
  • SOL added to reserve
  • Tokens removed from reserve
  • Price increases along the curve
Key milestones:
Market Cap% Supply SoldApprox PriceStatus
$00%~$0.000028Launch
$10k~15%~$0.000033Early
$30k~45%~$0.000042Mid
$69k~80%~$0.000064Graduation trigger
pump.fun的绑定曲线遵循一种恒定乘积公式变体：
Virtual SOL reserve: ~30 SOL (starting)
Virtual token reserve: 1,073,000,000 tokens (starting)

Price = SOL_reserve / Token_reserve
当代币被买入时：
  • SOL被添加到储备中
  • 代币从储备中移除
  • 价格沿曲线上涨
关键里程碑：
市值已售供应量占比近似价格阶段
$00%~$0.000028上线
$10k~15%~$0.000033早期
$30k~45%~$0.000042中期
$69k~80%~$0.000064触发毕业

2. Tracking Pre-Graduation Tokens

2. 追踪毕业前代币

Data sources:
typescript
// Helius webhook for new pump.fun tokens
// Program ID: 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P

// Key accounts to monitor:
// - Bonding curve account (holds SOL + token reserves)
// - Global state (tracks graduation threshold)
// - Mint account (token metadata)
Metrics to track:
  • Current market cap (SOL in curve × SOL price)
  • Holder count and distribution
  • Buy/sell ratio
  • Volume velocity (buys per minute)
  • Creator wallet activity
  • Social signals (Twitter mentions, Telegram links)
数据来源：
typescript
// Helius webhook for new pump.fun tokens
// Program ID: 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P

// Key accounts to monitor:
// - Bonding curve account (holds SOL + token reserves)
// - Global state (tracks graduation threshold)
// - Mint account (token metadata)
需追踪的指标：
  • 当前市值（曲线中的SOL数量 × SOL价格）
  • 持有者数量及分布
  • 买卖比率
  • 交易量速度（每分钟买入次数）
  • 创建者钱包活动
  • 社交信号（Twitter提及量、Telegram链接）

3. Graduation Detection

3. 毕业检测

Graduation triggers when:
  1. Market cap reaches ~$69,420
  2. Bonding curve account is closed
  3. Raydium pool creation transaction fires
  4. LP tokens are burned (sent to dead address)
Detection methods:
typescript
// Monitor for graduation transaction pattern:
// 1. Instruction to pump.fun program with "migrate" discriminator
// 2. Creates Raydium AMM accounts
// 3. Burns LP tokens

// Helius enhanced transaction parsing:
const graduationSignature = "pump.fun:migrate";
Timing window:
  • Graduation tx confirms: T+0
  • Raydium pool active: T+1 to T+3 slots (~400ms-1.2s)
  • Arbitrage window: This brief gap
触发毕业的条件：
  1. 市值达到约$69,420
  2. 绑定曲线账户被关闭
  3. Raydium池创建交易触发
  4. LP代币被销毁（发送至死地址）
检测方法：
typescript
// Monitor for graduation transaction pattern:
// 1. Instruction to pump.fun program with "migrate" discriminator
// 2. Creates Raydium AMM accounts
// 3. Burns LP tokens

// Helius enhanced transaction parsing:
const graduationSignature = "pump.fun:migrate";
时间窗口：
  • 毕业交易确认：T+0
  • Raydium池激活：T+1至T+3个插槽（约400毫秒-1.2秒）
  • 套利窗口：这段短暂的间隔

4. Post-Graduation Dynamics

4. 毕业后动态

After migration to Raydium:
  • Liquidity: ~$12k split between SOL and token
  • Initial price: Matches final bonding curve price
  • LP burned: Cannot be rugged via LP removal
  • Trading: Standard AMM dynamics (slippage, price impact)
What changes:
AspectPre-GraduationPost-Graduation
Price mechanismBonding curveAMM (x*y=k)
Liquidity depthGrows with buysFixed at ~$12k
Rug vectorCreator abandonsConcentrated holders dump
SlippagePredictableDepends on trade size
迁移至Raydium后：
  • 流动性：约1.2万美元，在SOL和代币之间分配
  • 初始价格：与绑定曲线最终价格一致
  • LP代币已销毁：无法通过移除LP实现跑路
  • 交易：标准AMM动态（滑点、价格冲击）
变化对比：
维度毕业前毕业后
价格机制绑定曲线AMM（x*y=k）
流动性深度随买入量增长固定在约1.2万美元
跑路风险点创建者放弃项目集中持有者砸盘
滑点可预测取决于交易规模

Common Failure Modes + Debugging

常见故障模式与调试

"Token stuck at low MC"

"代币卡在低市值阶段"

  • Cause: No organic interest, creator not promoting
  • Detection: Flat volume, no new holders for hours
  • Action: Move on; most tokens die here
  • 原因：无真实关注度，创建者未推广
  • 检测：交易量平稳，数小时无新持有者
  • 操作：放弃；大多数代币在此阶段夭折

"Fake volume detected"

"检测到虚假交易量"

  • Cause: Bots or creator wash trading
  • Detection: Same wallets buying/selling in loops, volume >> new holders
  • Action: Discount reported metrics; check unique wallet count
  • 原因：机器人或创建者刷量交易
  • 检测：相同钱包循环买卖，交易量远大于新持有者数量
  • 操作：调低报告指标权重；查看独立钱包数量

"Graduation sniped"

"毕业被狙击"

  • Cause: Bots front-run migration, dump on Raydium
  • Detection: Large sells within first few blocks of Raydium pool
  • Action: Wait for dust to settle before entering; check post-grad holder changes
  • 原因：机器人抢先迁移交易，在Raydium上砸盘
  • 检测：Raydium池上线后的前几个区块出现大额卖出
  • 操作：等待市场稳定后再入场；查看毕业后持有者变化

"Price tanks immediately post-graduation"

"毕业后价格立即暴跌"

  • Cause: Early holders taking profit, low new demand
  • Detection: Sell pressure > buy pressure, holder count dropping
  • Action: Normal for most tokens; only concerning if concentrated dumps
  • 原因：早期持有者获利了结，新需求不足
  • 检测：卖出压力大于买入压力，持有者数量下降
  • 操作：大多数代币都会出现这种情况；仅当出现集中砸盘时需警惕

"Can't find Raydium pool after graduation"

"毕业后找不到Raydium池"

  • Cause: Migration takes 1-3 slots; indexers may lag
  • Detection: Graduation tx confirmed but no pool in UI
  • Action: Query Raydium program directly or wait for indexer sync
  • 原因：迁移需要1-3个插槽；索引器可能延迟
  • 检测：毕业交易已确认但UI中无池信息
  • 操作：直接查询Raydium程序或等待索引器同步

Quality Bar / Validation

质量标准/验证

Analysis is complete when:

$CATCOIN Post-Graduation Analysis

$CATCOIN 毕业后分析

Timeline:
  • Graduation: 14:32 UTC (tx: [LINK])
  • Peak MC: $142k (+105% from graduation)
  • Current MC: $28k (-60% from peak)
  • Time elapsed: 4h 23m
What happened:
  1. Graduation sniped by 3 wallets buying $2k+ in first 5 blocks
  2. Price pumped 105% in 20 minutes (FOMO + thin liquidity)
  3. Sniper wallets dumped at peak (identified: [WALLET1], [WALLET2])
  4. Cascade selling as retail panic exited
Holder changes (graduation → now):
  • Top 10: 45% → 22% (snipers exited)
  • Unique holders: 1,247 → 1,891 (+51%)
  • Creator wallet: Still holding 0.5%
Current state:
  • Liquidity: $11.2k (normal post-grad)
  • Volume (1h): $8,400
  • New buyers still entering (good sign)
Assessment: This is a typical "graduation snipe + dump" pattern. The snipers have largely exited. Current price may be closer to organic floor. Watch for:
  • Stabilization around $25-35k MC
  • Creator continued engagement
  • New holder growth rate
Risk: MEDIUM-HIGH The snipe dump is over, but recovery depends on community resilience.

时间线：
  • 毕业：14:32 UTC（交易链接：[LINK]）
  • 峰值市值：$142k（较毕业时上涨105%）
  • 当前市值：$28k（较峰值下跌60%）
  • 已过去时间：4小时23分钟
事件经过：
  1. 3个钱包在最初5个区块买入2000美元以上，狙击了毕业过程
  2. 20分钟内价格上涨105%（FOMO + 流动性稀薄）
  3. 狙击钱包在峰值砸盘（已识别：[WALLET1]、[WALLET2]）
  4. 散户恐慌离场引发连锁抛售
持有者变化（毕业时 → 当前）：
  • 前10名：45% → 22%（狙击者已离场）
  • 独立持有者数：1247 → 1891（增长51%）
  • 创建者钱包：仍持有0.5%
当前状态：
  • 流动性：$11.2k（毕业后正常水平）
  • 交易量（1小时）：$8,400
  • 仍有新买家入场（积极信号）
评估： 这是典型的「毕业狙击+砸盘」模式。狙击者已基本离场。当前价格可能更接近有机底部。需关注：
  • 市值在2.5万-3.5万美元区间企稳
  • 创建者持续互动
  • 新持有者增长速度
风险：中高 狙击砸盘已结束，但复苏取决于社区韧性。
