Base Launches Universal Web3 Sign-In and Payment Solutions

Base has introduced fixed rate loans to its blockchain platform. This development builds on the network's existing bitcoin-backed lending infrastructure, which previously reached $100m in collateral. The new fixed rate product offers borrowers predictable repayment terms, marking an expansion of Base's DeFi lending capabilities.

WalletConnect and Base have announced a partnership to implement **Native Account Abstraction (EIP-8130)** across all EVM-compatible chains. **What This Means:** - EIP-8130 brings account abstraction natively to Ethereum and EVM chains - The partnership aims to make this functionality available in every wallet - This could simplify user experiences across the entire EVM ecosystem Account abstraction allows for more flexible account management, including features like social recovery, gasless transactions, and batch operations without requiring users to manage complex wallet setups. The collaboration between WalletConnect, a widely-used wallet connection protocol, and Base, Coinbase's Layer 2 network, signals broader industry adoption of this Ethereum improvement proposal.

Cobalt launches in September with three key features: **Sponsorship** - Apps can cover your transaction fees, eliminating gas costs for users. **Batch calls** - Combine multiple transactions into a single action, reducing the number of wallet confirmations needed. **Session keys** - Grant apps permission to sign specific transactions automatically, streamlining the approval process. These features aim to simplify the user experience by reducing friction points like gas fees, multiple clicks, and repeated approvals.

**Tuyo**, a new money app built on Base, has introduced a payment card with an unusual twist: **every purchase you make might cost you nothing**. The concept is simple but intriguing - when you swipe the card, there's a chance your transaction will be free. The app markets this as "buy now, pay maybe," turning everyday purchases into a potential lottery. **Key features:** - Built on Base blockchain infrastructure - Payment card with randomized free transactions - Gamifies everyday spending The app represents another step in bringing crypto-native financial products into daily use, though questions remain about the economic model and how the "free" purchases are subsidized. No details have been released about the odds of receiving a free transaction or the mechanics behind the system.
