Ripple said it fixed a critical XRP bug that could have allowed unauthorized issuance of XRP and threatened the fixed supply of the token. The flaw was patched before it could be exploited and had no actual impact on the network. With vulnerability discoveries accelerating, the engineering team at Ripple is expanding AI-assisted testing and mathematical verification to systematically uncover long-standing latent weaknesses and strengthen protocol security.

Bitcoin long-term holders moved 32,000 BTC to exchanges on October 7 and 8, the second-largest single-day inflow since February 5. US government wallets shifted 17,200 BTC to a custody platform for the US Marshals Service, leaving 14,800 BTC of potential sell pressure. Spent coins averaged 712 days old versus 651 on July 14, and whether new demand absorbs this supply will shape the next move.

Zip Co Ltd (ASX: ZIP) shares have been sold down recently, but UBS says the business fundamentals look sound.

The XRP Ledger Foundation confirmed that a patched vulnerability did not create new XRP, with supply fixed at 100 billion at launch and about 99.986 billion existing today. The flaw, fixed in version 3.4.1 roughly two weeks ago, needed hundreds of crafted operations to trigger, so normal payments never exposed it. The Foundation will add formal verification and AI driven adversarial testing.

U.S. President Trump said on Truth Social that Russia and Ukraine agreed to an energy ceasefire effective immediately. Russia has not confirmed the deal. Ukrainian President Zelensky initially said he had no knowledge of it, then supported it and said Ukrainian forces received orders. Ukraine reported Russian Shahed drones and a glide bomb strike on a Kharkiv heat and power plant after the announcement.

Whale Alert reports that 133,800,000 USDC, worth 133,843,217 USD, was transferred from Aave to an address identified as Unknown Whale 1.

Starknet's STRK token more than doubled in seven days as its developers weighed leaving Ethereum to build a standalone Layer 1 blockchain. CoinGlass data captured at 20:28 UTC on Oct. 11 showed STRK at $0.1190, up 17.7% over 24 hours and 116.7% over the week. On Oct. 8, Starknet said it was actively considering a move to L1, targeting 2027 for what it describes as the first fully quantum-resistant network. Such a shift would end its reliance on Ethereum's underlying security layer. StarkWare CEO Eli Ben-Sasson has cast the potential transition as a response to mounting concern that advances in quantum computing and artificial intelligence could erode existing blockchain cryptography. In a post on X, he argued the quantum threat could arrive sooner than expected and that increasingly capable AI adds urgency to preparations. The debate follows recent AI-assisted progress in mathematical research. His case rests on preparing for a cryptographically relevant quantum computer. It does not show that AI can already break signatures deployed on blockchains. Starknet's ZK-STARK proof system depends on hash-based cryptographic assumptions rather than the elliptic-curve mechanisms that a sufficiently powerful quantum computer could break. The network also supports programmable accounts, letting users adopt alternative signature schemes without a network-wide upgrade. In June, StarkWare published a three-phase roadmap covering vulnerable hashing mechanisms, legacy smart contracts and dependencies inherited from Ethereum. Starknet controls the first two phases. The third hinges on Ethereum's own migration. Starknet currently runs as an Ethereum Layer 2, processing transactions separately while relying on Ethereum for settlement and data availability. That leaves its bridge infrastructure and Ethereum-based data commitments exposed to cryptographic dependencies beyond Starknet's direct control. In September, the Ethereum Foundation's Protocol cluster set a December 2029 target for quantum resistance across Ethereum's execution, consensus and data layers. An independent Starknet would need its own security and settlement model to replace the protections Ethereum provides. The Oct. 8 announcement sets out a consideration and a quantum-resistance goal, not an approved migration timetable. The same Oct. 11 CoinGlass snapshot showed about $258.5 million in futures open interest and $3.5 billion in 24-hour futures volume, alongside roughly $14.8 million in total futures liquidations over 24 hours. CoinMarketCap data checked on Oct. 11 showed about $720 million in 24-hour trading volume against a market capitalization of roughly $892 million. The rally comes ahead of an Oct. 15 token unlock. Tokenomist lists the date, and Starknet's published vesting schedule allows up to 127 million STRK to unlock each month for early contributors and investors through March 2027. At the Oct. 11 CoinGlass price, that maximum tranche would be worth about $15.1 million, equal to 1.27% of Starknet's original 10 billion-token supply. An unlock makes previously restricted tokens transferable. It does not establish how many recipients will sell.

LBTC redemptions on the Liquid Network have been paused 35 days after an attacker used an Elements flaw to take nearly 4,000 BTC. About 3,400 BTC came back, leaving 598.5 BTC worth 49.69 million dollars. Blockstream rejected the 10 percent bounty demand, and Elements v23.3.4 is now under external audit. No restart date is set, and holders exiting via Sideswap and Sideshift face weeks of delays.

Moonshot executives are in talks with shareholder Recurrent AI to settle an equity compensation dispute before the company's planned IPO, according to people familiar with the matter. Recurrent AI held a 9.5% stake in Moonshot at its founding and is now seeking compensation equivalent to 10.5% of the original shares, a payout that could exceed $700 million based on the company's latest $30 billion valuation.
