Sell V2

The sell_v2 instruction sells base tokens into a bonding curve using the curve's quote mint. Like buy_v2, it uses a single unified account interface for both SOL-paired and non-SOL-paired coins.

Accounts

#	Account	Seeds / derivation	init_if_needed / SOL cost
1	global	Pump PDA: seeds [b"global"].	-
2	base_mint	Base token mint for the coin being sold.	-
3	quote_mint	Quote mint for the coin. For SOL-paired coins, pass wrapped SOL: So11111111111111111111111111111111111111112.	-
4	base_token_program	Token program for base_mint. For create_v2 coins this is Token-2022: TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb.	-
5	quote_token_program	Token program for quote_mint. This is not necessarily the same as base_token_program.	-
6	associated_token_program	Associated Token Program: ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL.	-
7	fee_recipient	Fee recipient selected from the global config.	-
8	associated_quote_fee_recipient	Associated token account for quote_mint, owned by fee_recipient, using quote_token_program.	ATA rent if missing
9	buyback_fee_recipient	Buyback fee recipient checked against the global config.	-
10	associated_quote_buyback_fee_recipient	Associated token account for quote_mint, owned by buyback_fee_recipient, using quote_token_program.	-
11	bonding_curve	Pump PDA: seeds [b"bonding-curve", base_mint]. For SOL-paired coins, bonding_curve.quote_mint is Pubkey::default() and quote_mint should be wrapped SOL.	Rent top-up to make the account data length 115 bytes if it is smaller
12	associated_base_bonding_curve	Associated token account for base_mint, owned by bonding_curve, using base_token_program.	-
13	associated_quote_bonding_curve	Associated token account for quote_mint, owned by bonding_curve, using quote_token_program.	-
14	user	Transaction signer and seller.	-
15	associated_base_user	User's associated token account for base_mint, using base_token_program.	-
16	associated_quote_user	User's associated token account for quote_mint, using quote_token_program. For SOL-paired coins, this is seed constrained but native SOL is used for the transfer.	-
17	creator_vault	Pump PDA: seeds [b"creator-vault", bonding_curve.creator].	Rent-exempt top-up if needed
18	associated_creator_vault	Associated token account for quote_mint, owned by creator_vault, using quote_token_program.	ATA rent if missing
19	sharing_config	Pump Fees PDA: seeds [b"sharing-config", base_mint].	-
20	user_volume_accumulator	Pump PDA: seeds [b"user_volume_accumulator", user]. Initialized if needed, paid by user.	Rent for 137-byte account if missing: 0.0018444 SOL
21	associated_user_volume_accumulator	Associated token account for quote_mint, owned by user_volume_accumulator, using quote_token_program.	ATA rent if missing
22	fee_config	Pump Fees PDA: seeds [b"fee_config", pump_program_id].	-
23	fee_program	Pump Fees Program.	-
24	system_program	System Program: 11111111111111111111111111111111.	-
25	event_authority	Pump PDA: seeds [b"__event_authority"].	-
26	program	Pump program account.	-

Instruction Data

The sell_v2 instruction takes the following instruction data arguments.

#	Argument	Type	Description / validation	Optional?
1	amount	u64	Amount of base tokens to sell, in base token units. Must be greater than 0 and cannot exceed the user's base token balance.	No
2	min_sol_output	u64	Minimum quote amount the seller is willing to receive after protocol and creator fees.	No

Fee Recipients

All sell_v2 calls need a feeRecipient and a buybackFeeRecipient.

• For non-mayhem coins, choose one of the 8 normal fee recipients as feeRecipient.
• For mayhem mode coins, choose one of the 8 reserved fee recipients as feeRecipient.
• For all coins, choose one of the 8 buyback fee recipients as buybackFeeRecipient.

See Fee Recipients for the full address lists.

TS SDK

Sell SOL-Paired Coin

For SOL-paired coins, use wrapped SOL as the quoteMint.

import { PUMP_SDK } from "@pump-fun/pump-sdk";

const amount = new BN(100_000 * 10 ** 6);
const quoteAmount = new BN(0);
const quoteMint = NATIVE_MINT;
const quoteTokenProgram = TOKEN_PROGRAM_ID;

const sellInstruction = await PUMP_SDK.getSellV2InstructionRaw({
  user,
  mint,
  creator,
  amount,
  quoteAmount,
  tokenProgram: TOKEN_2022_PROGRAM_ID,
  quoteMint,
  quoteTokenProgram,
  feeRecipient,
  buybackFeeRecipient,
});

Sell Legacy SOL-Paired Coin

For legacy coins where the base mint uses the legacy SPL Token Program, pass TOKEN_PROGRAM_ID as both the base tokenProgram and quoteTokenProgram.

import { PUMP_SDK } from "@pump-fun/pump-sdk";

const amount = new BN(100_000 * 10 ** 6);
const quoteAmount = new BN(0);
const quoteMint = NATIVE_MINT;
const quoteTokenProgram = TOKEN_PROGRAM_ID;

const sellInstruction = await PUMP_SDK.getSellV2InstructionRaw({
  user,
  mint,
  creator,
  amount,
  quoteAmount,
  tokenProgram: TOKEN_PROGRAM_ID,
  quoteMint,
  quoteTokenProgram,
  feeRecipient,
  buybackFeeRecipient,
});

Sell USDC-Paired Coin

For USDC-paired coins, pass the USDC mint as quoteMint and the quote mint's token program as quoteTokenProgram.

import { PUMP_SDK } from "@pump-fun/pump-sdk";

const amount = new BN(100_000 * 10 ** 6);
const quoteAmount = new BN(0);
const quoteMint = new PublicKey("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v");
const quoteTokenProgram = TOKEN_PROGRAM_ID;

const sellInstruction = await PUMP_SDK.getSellV2InstructionRaw({
  user,
  mint,
  creator,
  amount,
  quoteAmount,
  tokenProgram: TOKEN_2022_PROGRAM_ID,
  quoteMint,
  quoteTokenProgram,
  feeRecipient,
  buybackFeeRecipient,
});

Rust SDK

The Rust client exposes sell_v2_instructions, which prepends the user's base/quote ATA creates and emits the sell_v2 instruction. The fetched BondingCurve carries the coin's quote_mint, so the same builder works for SOL-paired and non-native quote coins; only quote_token_program needs to match the quote mint's token program.

use pump_rust_client::{constants, PumpSdk};

let sdk = PumpSdk::new();
let global = client.fetch_global().await.expect("fetch_global");
let bonding_curve = client
    .fetch_bonding_curve(&mint)
    .await
    .expect("fetch_bonding_curve");

let mut ixs = vec![ComputeBudgetInstruction::set_compute_unit_limit(400_000)];
ixs.extend(
    sdk.sell_v2_instructions(
        &global,
        &bonding_curve,
        mint,
        constants::SPL_TOKEN_PROGRAM_ID, // quote_token_program
        user.pubkey(),
        300_000_000,                     // amount (base token units, 6 decimals)
        1,                               // min_sol_output (slippage floor, quote base units)
    )
    .expect("sell_v2_instructions"),
);
