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
| 2 | 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
