Pump.fun said it will add USDC trading pairs for newly issued tokens starting on May 21. Under the change, once a meme coin completes its bonding curve and graduates, its creator will be able to choose SOL or USDC as the quote asset for the liquidity pool. Existing graduated tokens that already trade against SOL will not be affected.
The update is being treated as one of the platform’s biggest structural changes since launch. Test tokens using USDC pairs, including one called “UpSide Down Cat,” have already appeared on the platform ahead of the rollout. For Solana’s meme coin market, that means the default path of locking fresh post-graduation liquidity into SOL now has an alternative.
Community Focus Turns to Future SOL Lockups
Pump.fun has long been seen as a major engine for Solana’s on-chain TVL. The report cited rough community estimates saying the platform’s bonding curve model has locked more than 5 million SOL into liquidity pools. That is why the addition of USDC pairs quickly led to questions about how much future demand for SOL could shift away.
Crypto analyst Schoen wrote on X that the change could weaken the stream of SOL being locked by newly graduated tokens. He linked the move to recent comments from Solana Foundation chair Lily Liu that meme coins do not define Solana, then argued that if a large share of new launches move to USDC pairs, “this is a huge loss” for future SOL TVL.
Traders See a More Stable Quote Asset
Not everyone views the move negatively. Crypto KOL Nate backed the decision on X, saying USDC pairs offer clear benefits for traders and token deployers, especially during periods of market volatility. In his view, using a stablecoin quote asset reduces direct dependence on SOL price swings and may also cut related selling pressure. He called it “a very good step.”
Nate also said that given Pump.fun’s trading scale, a strategic partnership with Circle cannot be ruled out. He added that USDC’s censorship resistance and freezing mechanics may also be part of the platform’s thinking. He described the rollout as an opening move rather than the final one, suggesting that more asset pairings could come later.
By bringing stablecoins into the post-graduation pairing process, Pump.fun is changing more than a single market setting. The move reaches into the way capital is parked inside Solana’s meme coin economy: one side sees pressure on future SOL lockups, the other sees a steadier pricing base for issuance and trading. That split is now out in the open, and on-chain activity after May 21 will be watched closely.
