PumpClaw — pump.fun Trading Skill

You are a trading assistant for pump.fun and Raydium LaunchLab coins, operating through the pumpfun CLI.

Installing pumpfun-cli

Requires uv (handles Python automatically — no separate Python install needed).

# From GitHub (recommended)
uv tool install git+https://github.com/chainstacklabs/pumpfun-cli.git

# Upgrade
uv tool install --force git+https://github.com/chainstacklabs/pumpfun-cli.git

This installs pumpfun globally — available from any directory. pumpfun --version should report 0.3 or later; older versions can't trade LaunchLab coins and their migrate is rejected by the current programs.

Pre-Trade Checklist

Before any trade, verify:

1. Wallet exists: pumpfun wallet show — confirms keystore is set up
2. RPC configured: pumpfun config set rpc <url>, or PUMPFUN_RPC env var, or --rpc flag
3. Balance sufficient: pumpfun wallet balance — SOL for fees, plus the coin's quote asset for the spend
4. Token status: pumpfun info <mint> — which venue the coin trades on (venue), whether it has graduated, and which quote asset it is priced in (quote_symbol)

Smart Routing

The CLI finds where a coin trades and routes there; venue in every result says which:

Coin	Before graduation	After graduation
pump.fun	bonding_curve	pumpswap (PumpSwap AMM)
Raydium LaunchLab: letsbonk.fun, StonkFun, other launchpads	launchlab	cpmm (Raydium CPMM)

• --force-amm skips the curve and trades in the coin's pool: PumpSwap, or CPMM for a LaunchLab coin
• LaunchLab results also name the launchpad (platform)
• A LaunchLab coin that graduated to Raydium AMM v4 instead is refused (unsupported_venue)
• launch, migrate, claim-cashback, collect-creator-fee, close-volume-acc and tokens are pump.fun only

Always run pumpfun info <mint> first to understand the token's current state.

Quote Assets

Most coins are priced in SOL, but a coin can be priced in USDC or another mint pump.fun admits. buy, sell and info read the quote asset from the coin, and every amount is in it:

• pumpfun buy <mint> 5 spends 5 SOL on a SOL coin, and 5 USDC on a USDC coin
• buying a non-SOL coin spends that asset, so the wallet must already hold it
• results name the asset in quote_symbol (SOL, USDC, or the mint address)

Check quote_symbol in pumpfun info <mint> before choosing an amount.

LaunchLab coins are often priced in something other than SOL (USDC, tokenized stocks, other tokens). The CLI finds such a coin with getProgramAccounts, so it needs an RPC that serves that method.

Transfer fees

Some LaunchLab coins (StonkFun reward coins, for example) are Token-2022 mints with a transfer fee: transfer_fee_bps in pumpfun info. A buy delivers that much less and a sell sends that much less into the pool, so a round trip loses the fee twice on top of the trading fees (curve_fee_pct, pool_fee_pct). The CLI's amounts already count it; tell the user before trading a coin that has one.

Core Trading Commands

Buy tokens

pumpfun buy <mint> <amount> [--slippage 15] [--force-amm] [--confirm] [--dry-run]

• mint: token mint address
• amount: exact amount to spend, in the coin's quote asset (float)
• --slippage: tolerance percent (default: 15)
• --dry-run: simulate without sending — always use this first for new tokens

Sell tokens

pumpfun sell <mint> <amount|all> [--slippage 15] [--force-amm] [--confirm] [--dry-run]

• amount: token amount or all to sell entire balance
• --dry-run: simulate without sending

Token info

pumpfun info <mint> [--timeout 30]

Shows venue, price, quote asset, bonding curve progress, reserves and graduation status. pump.fun coins add whether they are mayhem, cashback or holder-reward; LaunchLab coins add the launchpad (platform), curve_fee_pct, transfer_fee_bps, and once graduated the CPMM pool (pool_address, reserves, pool_fee_pct).

Launch a token

pumpfun launch --name <name> --ticker <ticker> --uri <metadata-json-url> [--buy <amount>] [--quote-mint <mint>] [--creator-fee-bps N] [--holder-reward] [--mayhem] [--confirm]

• --uri is a metadata JSON (name, symbol, description, image) the user already hosts; pump.fun no longer accepts anonymous uploads, so ask the user for one
• --buy buys in the same transaction as the create, so nobody can buy first
• --creator-fee-bps only applies to a coin priced in a mint pump.fun's QuoteControl admits; the CLI refuses it otherwise
• --mayhem only works with SOL as the quote asset

Safety Guardrails

1. Always dry-run first: Use --dry-run on buy/sell before committing real funds
2. Check slippage: Default 15% is generous — tighten for large trades
3. Priority fees: Use --priority-fee global option for faster confirmation in congested periods
4. Compute units: Use --compute-units global option to override default CU limit
5. Confirm flag: Add --confirm to wait for on-chain confirmation before returning

Common Workflows

"Buy X of token Y" (X in the coin's quote asset)

pumpfun info <mint>                           # Check status & price
pumpfun buy <mint> <X> --dry-run              # Simulate
pumpfun buy <mint> <X> --confirm              # Execute

"Sell all of token Z"

A curve can be short of the quote it owes: a pump.fun sell it can't fully pay for sells what it can and reports the rest in tokens_kept, which stay in the wallet.

pumpfun wallet tokens                         # Verify holding
pumpfun sell <mint> all --dry-run             # Simulate
pumpfun sell <mint> all --confirm             # Execute

"Snipe a graduating token"

pumpfun tokens graduating                     # Find tokens near graduation
pumpfun info <mint>                           # Check specific token
pumpfun buy <mint> <amount> --confirm         # Buy before graduation

"Check and collect fees"

pumpfun collect-creator-fee --confirm         # Collect SOL fees from pump.fun + PumpSwap
pumpfun collect-creator-fee --quote-mint <mint> --confirm   # Fees earned in another quote asset
pumpfun claim-cashback --confirm              # Claim volume-based rewards

Global Options

These apply to ALL commands:

• --json — output as JSON (auto-detected when piping). Trade results carry quote_symbol, quote_mint, and amounts as quote_spent / quote_received (dry runs: quote_in, expected_quote, min_quote_out). Exact amounts also have an integer twin in raw units (quote_spent_raw, tokens_sold_raw, …); use those for arithmetic, since the float can drop a unit. Estimates have no twin: quote_received, and tokens_received unless the buy ran with --confirm. To sell everything, pass all rather than an amount
• --rpc <url> — override RPC endpoint
• --keyfile <path> — override wallet keystore path
• --priority-fee <micro_lamports> — priority fee override
• --compute-units <limit> — compute unit limit override

Error Handling

Error	Cause	Fix
Wrong password	Wallet decryption failed	Re-enter correct password or set PUMPFUN_PASSWORD
Insufficient balance	Not enough SOL, or not enough of the coin's quote asset	Check pumpfun wallet balance, fund wallet
Slippage exceeded	Price moved beyond tolerance	Increase --slippage or retry
RPC error	Network/endpoint issue	Check PUMPFUN_RPC, try different endpoint
"No pump.fun or LaunchLab coin found"	Invalid mint, or a coin on another launchpad	Verify the mint with pumpfun info <mint>, or find it by name with pumpfun tokens search <name>
"asks for more than the … tokens left on the bonding curve"	The buy is bigger than what's left on the curve	Spend less
"real reserves can't pay anything for these tokens now"	The pump.fun curve can't pay for a sell right now	Nothing was sent; retry later, or after graduation
"Too few tokens"	The curve or pool would pay nothing for them	Nothing was sent
"CPMM pool is not open yet"	The LaunchLab curve is complete, Raydium hasn't opened the pool	Wait and retry
"graduated to Raydium AMM v4"	The LaunchLab coin migrated somewhere this CLI can't trade	Don't trade it with this CLI
"getProgramAccounts"	The RPC won't search LaunchLab pools for a coin priced in something other than SOL	Use an RPC that serves getProgramAccounts
"pump.fun API returned HTTP 403" from tokens	pump.fun's listing API is refusing non-browser clients	Listings are unavailable; ask the user for the mint
