Summary
The stablecoin market contracted over the past month, with Circle's USD Coin (USDC) driving most of the decline. According to monthly DeFiLlama data as of October 25, USDC contributed around 80% of the net 30-day drop among the 13 largest stablecoins, losing USD 4.69 billion in the period. The 13 tokens collectively lost USD 5.82 billion in net value. USDC's market capitalization stood at USD 71.743 billion, down USD 878.72 million in the last week. The total stablecoin market declined to USD 300.36 billion, a USD 12.73 billion loss since May 22. Tether's USDT fell less over the month, with a market cap of USD 182.423 billion, down USD 1.29 billion over 30 days, and retained 60.74% of the market. The data shows the decline in capitalization but does not by itself establish whether redemptions, investor withdrawals or other factors drove it.
In tokenized finance, Aviva Investors, in collaboration with Ripple, launched a tokenized share class of its Sterling Liquidity Fund on the XRP Ledger with an initial investment of GBP 50 million. The offering is part of Aviva's GBP 22 billion sterling money-market portfolio. According to Ripple's October 26 announcement, it is Aviva Investors' second tokenized money-market fund on XRPL, following a first launch in July 2026, and brings combined holdings across the two share classes to more than GBP 86 million. The Ireland-domiciled Aviva Investors Sterling Liquidity Fund was established in 2002. The investment is in a tokenized fund share class, not a direct holding of XRP tokens or the XRP Ledger network.
A security flaw in the Electrum Bitcoin wallet allowed malicious servers to trick users into authorizing payments that ultimately sent funds to attackers. Developers confirmed at least one user lost money after attempting to speed up a pending transaction and released an urgent software update. Electrum relies on external servers to retrieve transaction history and broadcast payments, and before the fix it trusted those servers to report pending transactions without verifying their signatures. According to the disclosure, an attacker controlling a malicious server could intercept a Bitcoin payment before it reached the network and replace it with a fraudulent transaction in the wallet history.
Separately, BloomTrading said in an October 26 statement that it would fully compensate nine affected wallets by transferring replacement funds to new addresses designated by their owners. The move followed reports that nearly USD 1 million in Solana was drained from users of its cryptocurrency trading bot. Blockchain investigators estimated that 9,408 SOL, worth approximately USD 954,000, reached an address suspected of receiving stolen cryptocurrency from 49 victims, though the relationship between all reported losses remains unclear.
In DeFi activity, Uniswap v4 trading volume reached USD 707 million over the past 30 days on Robinhood, according to a post by @ponsdotfamily. The figure refers specifically to v4 trading conducted through Robinhood and is not a total across all Uniswap trading channels. The reported volume points to growing retail participation in decentralized trading.
