Solana Became USDC’s Secret Weapon in 2025

The explosive growth of Solana was a decisive factor in USDC’s breakout year. More than 70% of all stablecoins circulating on Solana are USDC, making it the network’s default dollar. In early 2025 alone, Solana’s total stablecoin supply more than doubled, driven primarily by USDC inflows.

An unexpected catalyst amplified this trend: the launch of the TRUMP memecoin, whose main liquidity pools were paired with USDC rather than USDT. Traders rushing into Solana’s DeFi ecosystem first needed USDC, triggering a surge in usage that rippled across lending, swaps, and on-chain payments — all counted in transaction volume metrics.
