#2	description: Buy and sell tokens on Pump.fun bonding curves and AMM pools
#3	---
#4
#5	# PumpFun Trading
#6
#7	Execute buy and sell trades on the Pump.fun protocol using the native Pump SDK. Supports both bonding curve trading (pre-graduation) and AMM pool trading (post-graduation).
#8
#9	## Prerequisites
#10
#11	- Funded Solana wallet via `nanosolana birth`
#12	- `HELIUS_RPC_URL` configured
#13	- Understanding of bonding curve mechanics
#14
#15	## Trading Flow
#16
#17	### 1. Check Token State
#18
#19	Before trading, always check if the token is on the bonding curve or has graduated:
#20
#21	```typescript
#22	const sdk = new OnlinePumpSdk(connection);
#23	const summary = await sdk.fetchBondingCurveSummary(mint);
#24
#25	if (summary.isGraduated) {
#26	// Use AMM trading instructions
#27	} else {
#28	// Use bonding curve trading instructions
#29	}
#30	```
#31
#32	### 2. Buy on Bonding Curve
#33
#34	```typescript
#35	import { OnlinePumpSdk, getBuyTokenAmountFromSolAmount } from "nanosolana";
#36	import BN from "bn.js";
#37
#38	const sdk = new OnlinePumpSdk(connection);
#39
#40	// Fetch state
#41	const [buyState, global, feeConfig] = await Promise.all([
#42	sdk.fetchBuyState(mint, user),
#43	sdk.fetchGlobal(),
#44	sdk.fetchFeeConfig(),
#45	]);
#46
#47	// Calculate expected tokens
#48	const solAmount = new BN(100_000_000); // 0.1 SOL
#49	const expectedTokens = getBuyTokenAmountFromSolAmount({
#50	global, feeConfig,
#51	mintSupply: buyState.bondingCurve.tokenTotalSupply,
#52	bondingCurve: buyState.bondingCurve,
#53	amount: solAmount,
#54	});
#55
#56	// Build instructions
#57	const buyIxs = await sdk.buyInstructions({
#58	...buyState, mint, user,
#59	amount: expectedTokens,
#60	solAmount,
#61	slippage: 0.05, // 5%
#62	});
#63	```
#64
#65	### 3. Sell on Bonding Curve
#66
#67	```typescript
#68	import { getSellSolAmountFromTokenAmount } from "nanosolana";
#69
#70	const [sellState, global, feeConfig] = await Promise.all([
#71	sdk.fetchSellState(mint, user),
#72	sdk.fetchGlobal(),
#73	sdk.fetchFeeConfig(),
#74	]);
#75
#76	const tokenAmount = new BN(1_000_000_000);
#77	const expectedSol = getSellSolAmountFromTokenAmount({
#78	global, feeConfig,
#79	mintSupply: sellState.bondingCurve.tokenTotalSupply,
#80	bondingCurve: sellState.bondingCurve,
#81	amount: tokenAmount,
#82	});
#83
#84	const sellIxs = await sdk.sellInstructions({
#85	...sellState, mint, user,
#86	amount: tokenAmount,
#87	solAmount: expectedSol,
#88	slippage: 0.05,
#89	});
#90	```
#91
#92	## Risk Management
#93
#94	\| Control \| Value \|
#95	\|---------\|-------\|
#96	\| Always use slippage \| 3-5% recommended \|
#97	\| Check `bondingCurve.complete` \| Before trading \|
#98	\| Use `BN` for all amounts \| Never use JS `number` \|
#99	\| Max position per trade \| Follow Kelly Criterion \|
#100	\| Circuit breaker \| -10% daily → pause 24h \|
#101
#102	## Integration with Swarm
#103
#104	Swarm agents with the `sniper`, `momentum`, and `graduation` roles use this skill automatically via the OODA trading loop.
