[Pump.fun to Enable USDC Trading Pairs for Newly Issued Tokens, Existing SOL Trading Pairs Unchanged] According to SolanaFloor, Solana meme token issuance platform Pump.fun will enable USDC trading pairs for newly issued tokens starting May 21, while existing SOL trading pairs will remain unchanged. Previously, all tokens that completed bonding curves were migrated to the AMM PumpSwap, paired with SOL, and permanently burned. According to DefiLlama estimates, approximately 5.07 million SOL, valued at over $430 million, have been locked and removed from circulation since January 2024. With the shift to USDC, Pump.fun's revenue will primarily be settled in stablecoins, reducing the process of converting SOL-based fees into stablecoins.
