Aave Labs introduced Stable Vaults, fixed-rate stablecoin yield vaults built for easy integration into consumer applications. The product converts variable onchain lending rates into a fixed rate that applications commit to their users. Aave's infrastructure handles the rebalancing, cross-chain operations, and rate management as an all-in-one solution. It's designed for any business that wants to embed fixed-rate stablecoin yield into its product. Aave Labs uses Stable Vaults to power yield in the Aave mobile app. Operators choose which stablecoins to accept and which yield strategies to plug in, including Aave markets, Savings GHO, Veda vaults, or any ERC-4626 vault.

The EF Devcon Team opened speaker applications for Devcon 8, set to take place in Mumbai, India, from November 3–6, 2026. Applications are open to anyone building, researching, or teaching in the Ethereum ecosystem. Speakers can apply across four formats, including Lightning Talk, Talk, Mixed Format, or Workshop, and choose from nine tracks spanning Core Protocol, Privacy & Consent, Security, Applied Cryptography, and Permissionless Networks. Devcon expects the event to engage more than 10,000 attendees, though this year's program will accept fewer talks than Devcon 7,. Speaker applications close on August 6, 2026 at 23:59 UTC.

Relay Protocol, a cross-chain liquidity provider, confirmed reports of scam tokens vanishing from wallets after purchase on Robinhood Chain, describing a wave of tokens deliberately designed to remove themselves post-purchase. The mechanism is a type of honeypot scam, where the token's smart contract contains hidden logic that silently burns the buyer's balance to zero, or reroutes it to the deployer, once triggered by a subsequent block or a set transaction count since launch, so the balance appears briefly before disappearing entirely. Relay said funds spent on these tokens are not recoverable, but stressed the exploit is isolated to the scam token purchase itself, with private keys and other wallet balances unaffected.
