Stablecoins dominated crypto trading in Q1 as investors sought safety, while rising bot usage and declining retail flows pointed to shifting market dynamics, according to CEX.io. Stablecoins were a rare bright spot in an otherwise subdued crypto market in the first quarter, with supply growth and transaction activity pointing to sustained demand even as broader market conditions weakened. Total stablecoin supply increased by roughly $8 billion to a record $315 billion in Q1, according to data from CEX.IO. Although this marked the slowest pace of expansion since Q4 of 2023, it still represented growth during a period when the wider crypto market contracted.

Stablecoins accounted for 75% of total crypto trading volume during the quarter — the highest level on record. Read more

Drift said a durable nonce attack helped drive its Solana exploit, as critics questioned why stolen USDC moved for hours without a freeze.

The attack began on Wednesday, with the theft involving multiple assets, including Circle’s USDC (USDC) and various altcoins. Onchain data later showed that the exploiter swapped the majority of assets into USDC, with the funds later bridged to Ethereum. Read more
