Pump.fun, a Solana-based meme coin launch platform, will introduce USDC trading pairs for new tokens starting May 21. This move will complement the existing SOL trading pair. All previously bonded-curve tokens will transition to the AMM PumpSwap, paired with SOL, and will be permanently burned. Since January 2024, approximately 5.07 million SOL, valued at over $430 million, have been locked and removed from circulation, according to DefiLlama. The shift to USDC trading pairs will allow Pump.fun to settle revenues primarily in stablecoins, eliminating the need to convert SOL fees into stablecoins. This change aims to streamline operations and enhance liquidity options for users on the platform.
