A full list of Major Upcoming Events, to be updated

Blast announced it will shut down its Ethereum L2. Running the chain now costs more than it earns, and the team sees no credible path to making it sustainable.

Users are asked to withdraw everything to Ethereum mainnet, including balances in the Blast PWA. The withdrawal delay drops to 24 hours, but withdrawals pause for about a week first while Blast pulls its assets out of Lido. The regular interface works until October 26. After that, funds stay withdrawable directly through the Blast bridge contracts on L1.

About $32M is still locked on Blast, per DefiLlama. The BLAST token trades near $0.00037, about 99% below its all-time high.

Volantis raised an $88M Series A led by Lachy Groom and Abstract, bringing its total funding to $97M. Sam Altman, Jeff Dean, Dylan Patel and John Doerr also backed the startup.

Volantis builds AI inference systems that use light instead of wires to connect chips to memory. It says this lifts both memory capacity and bandwidth by over 10x, so models with 10T+ parameters can run at up to 10,000 tokens per second per user. The first target is coding agents that finish a task in 30 seconds instead of 30 minutes.

The team previously shipped first-of-their-kind products at NVIDIA, AMD, Broadcom and Ayar Labs. Its next chip iteration is already taped out.

Blast says it will shut down its Layer 2 network, citing operating costs that exceed revenue and no credible path to economic sustainability. The team is asking users to withdraw assets to Ethereum mainnet, including funds held in the Blast PWA.

Blast plans to reduce the withdrawal delay to 24 hours. Withdrawals will first pause for about a week while the team withdraws the network’s Lido assets. After that process, withdrawals will resume with the shorter delay.

Users can withdraw through Blast’s interface until October 26, 2026. Assets will remain withdrawable after that date through direct interaction with the Blast bridge contracts on Ethereum L1; Blast says it will publish instructions before the deadline.

Aave V3’s Loop Safe Module was exploited, with losses of about 114.09 ETH across two Safe multisigs. The attacker reportedly repaid roughly 1,300 WETH in debt to unlock and withdraw collateral.

SlowMist says the attacker spoofed Safe authentication with a fake Safe that returned true when asked whether the module was enabled. The vulnerable adapter then made an unrestricted call using attacker-controlled router and calldata, allowing the attacker to execute transactions through the victim Safes and drain WETH and Aave collateral.

The reported attacker address is 0x42c2…F9353. The vulnerable contract is 0x16bb…283d8.

The Ethereum Foundation launched zkAPI on mainnet with the Open Anonymity Project. Users pay for AI APIs with zero-knowledge proofs, so no account is tied to their prompts.

Credits go into an Ethereum vault in a single deposit. After that, each session is paid with a ZK proof: the AI provider sees the prompts but not the payer, and the payment server sees the spend but not the prompts. Funds can be withdrawn onchain even if every zkAPI server goes offline.

The same setup can also cover RPC queries, VPNs and payments between AI agents. zkAPI does not hide IP addresses, so the team suggests Tor for stronger privacy.

Ostium unveiled Gateway, a whitelisted API and liquidity layer for venues, family offices and pro traders. It follows the $23.75M hack of its LP vault in July.

Pricing moves off-chain, and Ostium targets execution under 100ms, down from more than a second. Traders get one stablecoin margin account with cross-margin and sub-accounts. Access is whitelisted, and withdrawals pass an anomaly check instead of being instant. Ostium says RWAs now make up over 50% of perps volume on many venues, and its own open interest peaked above $370M.

Beta opens to design partners in Q4. Kaledora and Marco will run Ostium as co-CEOs, and the current app keeps working for existing users.

BNB Chain went live on Phantom on October 1. Users can trade on the network once they update to the latest version of the app.

BNB Chain joins Solana, Ethereum, Base, Polygon and Bitcoin in the wallet. The addition comes after Phantom dropped Monad support in August. Both teams teased the launch shortly before with a "hello" post in Chinese.

— NEAR Intents halts after a $3.8M exploit, pledges full compensation

— Phantom adds BNB Chain Support

— Google introduces Gemini 4 Argon

— OpenAI introduces Dots

— Drift Foundation recovery update

Robinhood Wallet has integrated Arcus’ API, adding it as one of several routing providers for spot swaps of more than 190 stock tokens. Eligible users in supported jurisdictions can access Arcus’ liquidity and execution infrastructure through the wallet.

Arcus uses a request-for-quote model, where professional market makers compete to price each swap. Users whose trades route through Arcus may be eligible for Arcus Points, and limit orders are also planned through Robinhood Wallet’s dapp browser.

Arcus, built by the team behind dYdX, launched on Robinhood Chain in July. It says it has processed more than $5 billion in cumulative volume and has over 15,000 traders, with total value locked above $28 million.
