Similar to “Sign In With Ethereum,” but designed for agents, it aims to solve two major security risks: leaked API keys and insecure wallets embedded in agent runtimes. Built on ERC-8004 and ERC-8128, SIWA enables agents to create a wallet, register an onchain ERC-8004 identity, and authenticate requests using cryptographic signatures instead of shared secrets. Private keys never reside inside the agent. All signing operations are handled through a separate keyring proxy, allowing the agent to request signatures without ever accessing the private key.Coinbase Introduces Agentic WalletsCoinbase Developer Platform introduced Agentic Wallets, the first wallet infrastructure purpose-built for autonomous AI agents. The wallets allow agents to independently send, receive, trade, and manage funds onchain without constant human intervention. Agentic Wallets include programmable spending controls, non-custodial identity, and gasless transactions on Base. They’re powered by the x402 protocol and built on Coinbase’s CDP Wallet infrastructure, with private keys secured in Trusted Execution Environments (TEEs). Developers can launch Agentic Wallets in minutes via a simple CLI, equipping agents with financial capabilities and financial autonomy.UniswapX To Support BUIDLUniswap Labs partnered with tokenization platform Securitize to enable trading of BlackRock’s USD Institutional Digital Liquidity Fund (BUIDL) on UniswapX. Through the integration, eligible whitelisted investors can swap BUIDL shares for USDC using UniswapX’s RFQ (request-for-quote) system. UniswapX is a permissionless, auction-based liquidity aggregation protocol that sources both onchain and offchain liquidity to deliver competitive pricing. The integration expands liquidity options for BUIDL holders. BUIDL remains restricted to qualified institutional investors and high-net-worth qualified purchasers.Ondo Brings Tokenized Stocks To DeFiOndo Finance partnered with Chainlink to provide oracle pricing for its tokenized U.S. stocks and ETFs on Ethereum via Ondo Global Markets. The integration enables tokenized equities to be used as collateral in DeFi lending markets, with Euler now supporting borrowing of stablecoins against the real world assets. The collaboration unlocks liquidity and yield for equities.Other NewsTeku v26.2.0 releaseCharon v1.8.2 releaseTheDAO funds SEAL 911Xatu execution trace dataRequirements for zkVMZK-based API usage protocolHoudini launches randomizerOctant announces Octant LabsPrivacy ecosystem mapOP yield opportunitiesAave expands to MantleUniFI AVS awarded EIGEN grantStatus FIRM stablecoinAztec proceeds with TGEBase releases leaderboardsDisclaimer: Content is for informational purposes only, not endorsement or investment advice.
