Circle recently announced an expansion of its USDC supply on the Solana network. Earlier this year, Binance's stablecoin reserves dropped from nearly $44 billion to $36 billion, coinciding with a decline in trading volume and liquidity on the BNB chain. In contrast, on March 18, USDT saw an inflow of $2.2 billion, marking the largest daily inflow since November 2025.
Since the end of 2024, Solana has maintained a leading position in decentralized trading activities. Platforms such as Raydium, Jupiter, PumpSwap, Orca, Meteora, and HumidiFi have driven stable trading volumes. Currently, USDC accounts for 52% of the $14.7 billion in circulating stablecoins on Solana.
Additionally, the on-chain performance of tokenized stocks on Solana has reached approximately $1 billion. Market data indicates that tokenized commodities and funds on the network are also on the rise. Meanwhile, Global Dollar has surpassed the $1 billion supply milestone this week.
In response to post-quantum pressures, Circle released a paper on the risks of quantum computing to blockchain cryptography. The company stated it is "actively planning" its response measures for its Arc Layer-1 network. Following the release of this report, Google updated its warning that "Quantum Day" (Q-Day) could arrive as early as 2029.
Arc aims to integrate quantum resistance from the outset through long-term validator enhancements. Circle emphasizes its plan to translate theoretical protections into practical deployments, ensuring coordination with various validators and infrastructure partners.
Moreover, the Bitcoin developer community has also advanced related preparations this year. On February 11, developers merged BIP-360 into the official codebase, outlining early preparatory steps for the Bitcoin protocol in the post-quantum era.
