• Basenames is launching via Dutch auction.

• Dune Analytics enables NFT mints for Dune charts.

• Hardhat releases a development update.

• Optimism Retro Funding 5 goes live this week.

Base revealed that access for its Base.eth subnames will open on Tuesday, August 20th. The domain names will be available through a Dutch auction sale with a gradually decreasing premium fee over the first 36 hours. The premium fee will start at 100 ETH, decreasing to 0.39 ETH over the first 12 hours. Once the Dutch auction ends, no premium fee will be applied. Base initially introduced Basenames to a limited group of users during Base Camp in July. Basenames are third-level domains based on the Base.eth second-level ENS domain. Users can currently search for Base.eth subname availability at base.org/names.

Dune Analytics, a platform for querying blockchain data using SQL, introduced "Mint Moment," a feature that allows users to mint and collect Dune charts as NFTs on Base. The feature is facilitated by an integration with Zora, enabling protocol rewards for users and Dune builders. Users can capture significant moments in time as NFTs, such as TVL, volume, and transaction milestones. The initiative creates a new revenue stream for Dune creators, who earn a 0.000333 ETH fee for each mint originating from their dashboards. Dune wizards need to connect their wallets to their accounts to enable minting.

Ethereum tooling provider Hardhat released an update on the Ethereum Development Runtime (EDR), a Rust-based runtime implementation. EDR allows features like Solidity stack traces and transaction details to be accessed across multiple languages via WASM. The team is working on stabilizing EDR and ensuring compatibility with existing plugins. The team is also preparing for Hardhat 3, the next major release, which will introduce OP Stack simulation support and Solidity testing capabilities. Hardhat is a development environment and task runner for Ethereum smart contracts. It simplifies the process of writing, testing, and debugging contracts written in EVM-compatible languages.

Applications for Optimism’s fifth retroactive funding round will open this Thursday, August 22nd. This round will distribute 8 million OP tokens to contributors to the OP Stack. Eligible projects include Ethereum core contributions, such as clients, OP Stack research and development, and OP Stack tooling. Applications will close on September 5th.

Gm frens,

In 2022, I started ETH Daily to keep the world updated on Ethereum, consistently covering innovations like The Merge and ZK-EVM races. Since then, the podcast has now hit 530 episodes, 300,000 downloads, and 3,600 hours listened.

In June, I took ETH Daily onchain with Pods Media.

OP Labs proposed the Granite Network Upgrade to address security vulnerabilities discovered in the network’s Fault Proof System. The bugs were identified during audits by Spearbit, Cantina, and Code4rena. The upgrade includes L1 smart contract changes and an L2 hardfork to resolve the issues. While user assets are not at risk, OP Labs activated the permissioned fallback mechanism as a precaution. The fallback restricts output proposals to be temporarily handled by the Optimism Foundation. Pending governance approval, the upgrade will go live on September 10th, after which the permissionless system will be restored.

Voting is now open on a proposal to deploy Aave V3 on zkSync Era. If approved, users will be able to deposit USDC, USDT, WETH, wstETH, and ZK as collateral to take out loans. Borrowing and flash loan functionalities will also be enabled for the assets. The loan-to-value (LTV) ratios will range from 71% to 75%, with liquidation thresholds set between 45% and 78%. The ZK token will have an initial supply cap of 18 million, a measure intended to manage risk by limiting the protocol’s exposure to highly volatile assets. Aave also plans to support liquidity mining for ZK, offering depositors a variable APR. Voting on the proposal closes on Tuesday, August 20th.

Chainlink Data Streams and Verifiable Random Functions (VRFs) are now live on Base, providing developers with access to real-time, low-latency market data and secure random number generation. The tools enhance the scalability and speed of applications. Chainlink VRF, already widely used by Ethereum applications like PoolTogether, ensures verifiable random outcomes. Base now supports Chainlink’s full product suite, including CCIP, Functions, Automation, and Proof of Reserve.

Base launched acceptusdc.com, a resource kit designed to help small businesses start accepting USDC for payments. Small businesses can request a "We accept USDC" sticker pack and submit their business to be included in a directory featuring all merchants that already support USDC in their business. The initiative highlights that using USDC reduces fraud and chargeback events.
