Pump Developer Updates

Hello everyone, On Thursday, May 21, 2026, we will be enabling USDC mint as a quote mint for creating and trading pump coins. * Please note that USDC-paired coins can only be traded using the new V2 instructions announced earlier. * SOL paired coins will continue to be traded in native SOL even though the quote mint needs to be passed as the wrapped SOL mint. * All legacy instructions will continue to work for SOL paired coins. Official docs: https://github.com/pump-fun/pump-public-docs New documentation has also been added for creator fee-related V2 instructions: • Collect Creator Fee https://github.com/pump-fun/pump-public-docs/blob/main/docs/instructions/COLLECT_CREATOR_FEE.md • Creator Fee Sharing https://github.com/pump-fun/pump-public-docs/blob/main/docs/instructions/CREATOR_FEE_SHARING.md

Hello everyone. We just upgraded the Bonding curve contract for a new non breaking feature. Happy to announce support of USDC as a quote mint for creating and trading Pump meme coins. As part of this upgrade, we have rolled out 3 new instructions, buy_v2, sell_v2 and buy_exact_quote_in_v2. These new instructions are meant to unify the trading interface so the same instruction can be used to trade USDC and SOL paired coins with no optional accounts depending on the coin mint. quote_mint needs to be passed as the wrapped SOL mint to trade coins paired with SOL. The trading and transfer will continue to happen identical to legacy buy, sell and buy_exact_quote_in using native SOL. Please note: We are only announcing the rollout of the new instructions today. USDC paired coins cannot be created until next week. There will be a 72 hours notice before its enabled. For more technical details of the new instructions, please refer to this doc: https://github.com/pump-fun/pump-public-docs New rust sdk: https://crates.io/crates/pump-rust-client

━━━━━━━━━━ PROGRAM UPGRADE ━━━━━━━━━━ Hi. We will be doing a breaking program upgrade on April 28th, 16:00 UTC, to both the pump bonding curve program and the pump swap amm program.

## One-Time Creator Reward Distribution Policy This update only affects fee-sharing configuration. Trading instructions are unchanged and do not require an upgrade. TLDR: After the first configuration, reward distribution is locked and cannot be changed. What changed: - Reward distribution can be configured only once. - You can configure it using either updateFeeShares or updateSharingConfigWithSocialRecipients. - After it is configured, it is locked and cannot be changed again. What did not change: - Buy and sell instructions are unchanged. Migration/compatibility notes: - Reward distributions created before this policy are treated as final (locked). - RevokeFeeSharingAuthority and TransferFeeSharingAuthority are no longer supported. - If you are unsure whether a reward distribution is still editable, call isSharingConfigEditable from the sdk. Sdk: https://www.npmjs.com/package/@pump-fun/pump-sdk/v/1.32.0 Docs: https://github.com/pump-fun/pump-public-docs?tab=readme-ov-file#one-time-creator-reward-distribution-policy

Hi devs — we've shipped Tokenized Agents. Tokenized Agents allow agents to collect revenue and use a portion of it for buybacks. This does not alter the trade flow — both buy and sell behavior remain the same. This is an entirely new smart contract that works on top of our Pump bonding curve and Pump AMM smart contracts. To create a tokenized agent, please use the NPM package: @pump-fun/agent-payments-sdk. After creating the bonding_curve on the Pump bonding curve program, you can send a transaction with the instruction to create a Tokenized Agent. To initialize it, use the following ix: """ import { PumpAgentOffline } from "@pump-fun/agent-payments-sdk"; ... const agentInitializeIx = await PumpAgentOffline.load(mint).create({ authority: creator, mint, agentAuthority: creator, buybackBps: buybackBps, }); """ The buybackBps parameter represents how much of the agent's revenue is reserved for buybacks, which happen automatically over time. Agents can also use functions to verify whether an invoice has been paid and to generate a transaction that a user can send to pay an invoice via the skill here: https://github.com/pump-fun/pump-fun-skills/blob/main/tokenized-agents/SKILL.md

Hi devs — we’ve shipped Creator Fee V2 integration guidance (docs + SDK helpers). This is not an on-chain update, but you may need to adjust your integration to correctly support all creator-fee configurations. - SDK update: @pump-fun/pump-sdk@1.30.0 (new helper functions) https://www.npmjs.com/package/@pump-fun/pump-sdk/v/1.30.0 - Docs / requirements: GitHub recipient + social fee PDA requirements https://github.com/pump-fun/pump-public-docs?tab=readme-ov-file#github-recipient-and-social-fee-pda-requirements Why you should care (quick checklist): - Support multiple creators on a coin - Correctly add a GitHub account as a creator *(many top apps still do this wrong)* - Detect when a coin has multiple creators + their addresses - Detect when a creator is a GitHub handle - Revoke authority to change creators If you display creator fees or attribute creators anywhere, please review + validate your integration against the updated docs.

Cashback Rewards allows token creators to create coins with "cashback" enabled which redirects the creator fee to the users. Each user would get the creator fee on their swap volume as cashback rather than paying that fee to the coin creator. This is a backwards compatible change, so if you do not update to the latest IDsL/SDKs it will work but cashback will not be enabled. ## Integration You can also use our Typescript SDKs for easier integration: - [Pump SDK](https://www.npmjs.com/package/@pump-fun/pump-sdk) - Latest version is 1.28.0 - [PumpSwap SDK](https://www.npmjs.com/package/@pump-fun/pump-swap-sdk) - Latest version is 1.14.0 - IDLS: https://github.com/pump-fun/pump-public-docs/tree/main/idl - Docs: https://github.com/pump-fun/pump-public-docs/blob/main/docs/PUMP_CASHBACK_README.md ## Changes to Instructions Cashback is only given to the user if the buy/sell instruction appends the proper remaining accounts. If the coin traded is a cashback coin but the cashback remaining accounts are now added, then the creator fee will go to the creator as it normally would. ### Bonding Curve Buy Instructions No change. Cashback is handled automatically if the coin has cashback enabled. ### Bonding Curve Sell Instruction Expects the UserVolumeAccumulator PDA for the Pump program at the 0th index in the remaining accounts with isWritable: true ### Pump Swap Buy Instruction Expects the WSOL associated token account of the UserVolumeAccumulator for the Pump AMM program (this is different than same account for the Pump program) at the 0th index of the remaining accounts. ### Pump Swap Sell Instruction Expects the WSOL associated token account of the UserVolumeAccumulator for the Pump AMM program (this is different than same account for the Pump program) at the 0th index of the remaining accounts. Expects the UserVolumeAccumulator for the Pump AMM Program (used to derive the WSOL ATA above) at the 1st index of the remaining accounts. ### Create V2 New parameter expected for create_v2 instruction which is an OptionBool to define whether the coin has cashback enabled or not. In typescript this is a tuple, so it would look like [true]. ### Bonding Curve Claim Cashback New claim_cashback instruction for the Pump program. No parameters needed. It transfers native lamports from the UserVolumeAccumulator to the user. ### Pump Swap Claim Cashback New claim_cashback instruction for the Pump AMM program. No parameters needed. It transfers WSOL from the WSOL ATA of the UserVolumeAccumulator to the user's WSOL ATA. The user's WSOL ATA is expected to exist before hand, so use "create idempotent associated token account" instruction before the claim instruction if need be. ## Account Changes ### Bonding Curve New is_cashback_coin: bool field on the BondingCurve account. ## Reading Unclaimed Cashback It is important to note that there is an UserVolumeAccumulator account for both the Pump (bonding curve) program and Pump Swap (AMM) program. They share a seed "user_volume_accumulator" with the program ID being the only difference in its seeds.

# Creator Rewards Sharing - Developer Update ## Overview Creator Rewards Sharing allows token creators to split their creator fees with multiple recipients. Instead of all fees going to a single wallet, creators can configure a list of shareholders with custom percentage splits. ## Dynamic creator_vault Address This update will make some coins' creator_vault point to new addresses. To ensure buy and sell instructions work seamlessly, always fetch the latest creator on-chain. Do not use cached addresses for bonding_curve.creator or pool.coin_creator. The derivation logic remains the same, so no code changes are needed if you're already fetching fresh data. ### Pre-Graduation Coins (Bonding Curve) const bondingCurve = await pumpProgram.account.bondingCurve.fetch(bondingCurvePda); const creatorVault = PublicKey.findProgramAddressSync( [Buffer.from("creator-vault"), bondingCurve.creator.toBuffer()], PUMP_PROGRAM_ID )[0]; ### Graduated Coins (AMM Pool) const pool = await pumpAmmProgram.account.pool.fetch(poolPda); const coinCreatorVaultAuthority = PublicKey.findProgramAddressSync( [Buffer.from("creator_vault"), pool.coinCreator.toBuffer()], PUMP_AMM_PROGRAM_ID )[0]; ## How Fee Distribution Works 1. Fees accumulate in the creator_vault during buy/sell transactions as before 2. Creator enables sharing by calling create_fee_sharing_config - this changes the coin_creator field to the sharing_config PDA 3. Creator configures shareholders via update_fee_shares with addresses and basis points (must total 10,000 bps = 100%) 4. Fees are distributed by calling distribute_creator_fees on the pump program, which splits the vault balance to shareholders based on their share percentages ## Testing Here are some examples coins with creator rewards sharing enabled: - Cmzo3D5XwdzC2jzAbb4x8kJinyHAbHBM9s58kd8Tpump (pump) - 5x9nfwrY4DywKNANjorjLFEJkXjut1iPSYXDgbTS1PG9Bqa4rKbnZPkJj55UqiHLWLLBn1XGHJZmtd6rAxycwyB7 (pump-amm)

## Dynamic creator_vault Address Hi, we will be pushing an update to our programs on Fri Jan 9, afternoon UTC. This update will make some coins' creator_vault point to new addresses. To ensure buy and sell instructions work seamlessly, always fetch the latest creator on-chain. Do not use cached addresses for bonding_curve.creator or pool.coin_creator. The derivation logic remains the same, so no code changes are needed if you're already fetching fresh data. ### Pre-Graduation Coins (Bonding Curve)

const bondingCurve = await pumpProgram.account.bondingCurve.fetch(bondingCurvePda);
const creatorVault = PublicKey.findProgramAddressSync(
  [Buffer.from("creator-vault"), bondingCurve.creator.toBuffer()],
  PUMP_PROGRAM_ID
)[0];

### Graduated Coins (AMM Pool)const pool = await pumpAmmProgram.account.pool.fetch(poolPda);
const coinCreatorVaultAuthority = PublicKey.findProgramAddressSync(
  [Buffer.from("creator_vault"), pool.coinCreator.toBuffer()],
  PUMP_AMM_PROGRAM_ID
)[0];

If you already fetch the latest bonding_curve.creator and pool.coin_creator from the chain before building your buy and sell instructions, no code changes are needed.

Hi all, We have pushed a non breaking program upgrade on the bonding curve and pump swap program. Changes as part of this upgrade: 1. The global_volume_accumulator account on the buy instruction of bonding curve and pump swap do not need to be mutable anymore. 2. New fee recipients for mayhem mode: We have introduced 7 new fee recipients that can be used for the buy and sell instruction that can be used when bonding_curve.is_mayhem_mode = true and pool.is_mayhem_mode = true. They can be found in the global and global_config accounts in bonding curve and pump swap respectively. Any of the following 8 fee recipients can now be used:

[ 'GesfTA3X2arioaHp8bbKdjG9vJtskViWACZoYvxp4twS', '4budycTjhs9fD6xw62VBducVTNgMgJJ5BgtKq7mAZwn6', '8SBKzEQU4nLSzcwF4a74F2iaUDQyTfjGndn6qUWBnrpR', '4UQeTP1T39KZ9Sfxzo3WR5skgsaP6NZa87BAkuazLEKH', '8sNeir4QsLsJdYpc9RZacohhK1Y5FLU3nC5LXgYB4aa6', 'Fh9HmeLNUMVCvejxCtCL2DbYaRyBFVJ5xrWkLnMH6fdk', '463MEnMeGyJekNZFQSTUABBEbLnvMTALbT6ZmsxAbAdq', '6AUH3WEHucYZyC61hqpqYUWVto5qA5hjHuNQ32GNnNxA' ]

Updated IDLs can be found here: https://github.com/pump-fun/pump-public-docs

Hi all, Mayhem mode and create v2 will now be enabled on 12th November 12:00 UTC instead of 11th November.

Hi all, On 11th November at 12:00 UTC, we will enable 2 new breaking features. 1. New token creation standard with token2022 called create_v2 2. Mayhem Mode Please refer here for the updated IDLs and IDL types: https://github.com/pump-fun/pump-public-docs Please note: 1. Any coin created with the usual create instruction and owned by the legacy token program can be traded the same way as before. This is not a breaking change for trading or creating such coins, you can continue to use the same accounts and instruction data. 2. Any new coin created after 11th November at 12:00 UTC with create_v2 will be owned by the Token2022 program. Creating and trading such accounts will need changes as described here: https://github.com/pump-fun/pump-public-docs/blob/main/README.md Program is updated on devnet for testing with both features enabled.

The pump bonding curve contract and the pump swap contract were upgraded earlier today at: November 5, 5:02pm UTC. The bonding curve upgrade was a routing upgrade with no breaking changes but Pump swap has breaking changes as mentioned earlier.

Hi all, we will be doing a breaking program upgrade on pump swap on Tuesday, 4th November, 14:00 UTC. As part of the change, we require you to mark the pool account at account index 1 in pump swap buys and sells as mutable ( as opposed to readonly ). Please make the changes as soon as possible, your integration will not break if you make it mutable before we do the program upgrade. IDL change for reference: https://github.com/pump-fun/pump-public-docs/commit/ff9cbf8238b4e459864fed415465cc8163113d1c

The pump bonding curve contract and the pump swap contract were upgraded earlier today at: October 17, 2025 16:47:00 UTC. It was a routine upgrade with no breaking changes.

Hello. The new fee schedule from here has been deployed on Devnet already and can be tested there

Hi all, today at 20:00 UTC we will deploy a change that makes the two additional accounts for the new fee structure mandatory — these accounts are currently optional. Shortly after verifying that this works we will deploy the fee schedule change outlined above. There will be 1 hour of notice before the fee schedule changes go live.

Hello. We already pushed on Devnet the update which makes the 2 new fee accounts on buy / sell required. This will be pushed to Mainnet on Monday too.
