Ripple is scheduled to release 1 billion XRP from escrow on Sunday, November 1, 2026, part of its monthly token release program. The unlock may add to XRP's available market supply, though it does not mean all 1 billion tokens will be sold. Ripple has historically returned most of each release to escrow, retaining a portion for operations, liquidity and ecosystem activities. Onchain data shows two Ripple-controlled wallets still held 500 million XRP each as of October 29. Both received their tokens in the October 1 unlock and have not sent any out since. That leaves an unusual supply picture heading into November: Ripple could draw another 1 billion XRP while the previous allocation sits in its wallets. The upcoming release covers two escrow accounts of 500 million XRP each. Reaching the scheduled date does not move the tokens by itself. Ripple must submit an EscrowFinish transaction to complete the release, so the scheduled unlock should not be read as a confirmed transfer or sale. Ripple launched its escrow program in December 2017, locking 55 billion XRP, or 55% of the cryptocurrency's 100 billion maximum supply, into time-locked contracts. The design was meant to make XRP supply more predictable through monthly releases of up to 1 billion tokens, with unused amounts returned to new escrow contracts instead of entering circulation. Recent releases have largely followed that pattern. Onchain tracking shows Ripple relocked about 700 million XRP, or 70% of each monthly release, in the 12 months through October 2026, leaving roughly 300 million XRP outside escrow each month for operations, liquidity provision and ecosystem activities. The unlock lands in a difficult market for XRP. U.S. spot XRP exchange-traded funds recorded $3.61 million in outflows in the week to October 29, raising questions about institutional demand. Large holders kept accumulating: wallets holding at least 10 million XRP controlled 46.87 billion tokens collectively, about 68.5% of circulating supply, Finbold reported. XRP traded at $1.24 at press time, down about 0.9% over 24 hours and more than 2% on the week. At that price it sits below both its 50-day simple moving average of $1.39 and its 200-day SMA of $1.28, a bearish technical signal. The 50-day SMA remains above the 200-day, so a longer-term bearish crossover has not occurred. The 14-day Relative Strength Index stood at 37.46, showing weakening momentum but holding above the oversold threshold of 30. XRP remains vulnerable to further downside; a rebound in buying pressure could help it reclaim the $1.28 200-day SMA as a first technical hurdle.

zkLink lost about $783,000 after an attacker used residual validation values in transient storage to forge batch roots and complete 12 withdrawals, one ETH and eleven ERC20. The attacker wrote a legitimate value through a real crosschain message, reused it within the same transaction, and injected a forged root through relay and gateway contracts. The value was not cleared or bound to the call.

The Recall Foundation is winding down operations and will burn about 358.6 million RECALL tokens, roughly 35.86% of total supply. The foundation said further development is "not commercially viable." Holders will receive no buyback, redemption or distribution.
