Optimism launched the Superchain Developer Console, a new resource portal designed for developers building on the Superchain. The console includes resources for all seven Superchain members, including access to testnet funds, funded paymasters, Safe smart wallet integrations, quick start guides, and personalized UX feedback. The console features dedicated support channels for developers, up to $200 in contract deployment rebates, and marketing support opportunities. Alchemy, Gelato, Quicknode, and Thirdweb are also offering promotional credits for Superchain builders. The initiative aims to ignite growth and reduce the operational costs for developers.

Securitize formally announced its partnership with BlackRock to launch the BlackRock USD Institutional Digital Liquidity Fund, a tokenized fund on Ethereum that offers accredited investors with access to USD yield. Coined as BUIDL, the fund offers a stable asset that is pegged to the US dollar and backed by U.S. Treasuries. BUILD is rebasing and accrued yield is distributed to investors as new tokens onchain. Securitize says it enables for onchain ownership and trading of fund shares, providing instant settlement and transparency to investors. Initial fund partners include Coinbase, BitGo, Anchorage, and Fireblocks. Mountain Protocol is also tapping into the fund as a seed client.

EigenLayer released an article outlining the risks involved with Liquid Restaking Tokens (LRTs), which are created by independent protocols that use native restaking on EigenLayer to provide a liquid solution. The article notes that while LRTs introduce innovation, they also add complexity and risk to the restaking ecosystem. The article notes that LRT projects could be under risk-taking pressure to compete with each other. EigenLayer highlights risks related to looping and leveraged strategies that could amplify losses, as well as the issues arising from liquidity challenges and unclear unstaking processes, resulting in losses when users are forced to sell their assets in markets with low liquidity.

Token streaming platform Sablier raised a $4.5 million seed funding round. The company intends to use the funds to grow its team, enhance its existing product suite, and launch a new payment platform dubbed Sablier V3. Sablier enables users to create token streams featuring various locking mechanisms, such as linear, cliff, timelock, and exponential. Sablier also supports voting power from streaming governance tokens. Data from DeFiLlama indicates that Sablier's TVL in its V1 and V2 releases is $5.3 million.

Ethereum core developers agreed to include Increase Max Effective Balance EIP-7251 in the Electra upgrade. Also called Max EB, the update allows validators to hold an effective balance between 32 and 2,048 ETH. Currently, any validator balance above 32 ETH is not actively staked and does not earn attestation and validation rewards. With the increase, validators will now earn consensus layer rewards for balances over 32 ETH. Any balance above 32 ETH will be subject to slashing. The update also reduces the operational overhead for large stakers by minimizing the number of validators required. Core developers also considered Inclusion Lists EIP-7547 for inclusion in the Pectra upgrade.

Ethereum core developers disclosed a security vulnerability that existed on Ethereum mainnet from the Merge until the recent Dencun hard fork. The bug could have been exploited to execute a denial-of-service attack. It emerged due to differing message size limits for RPC communications that were established after the Merge. The vulnerability allowed the creation of blocks exceeding RPC size limits for some clients while remaining valid for others, disrupting consensus. It could cause a chain split leading to potential reward losses for block proposers. Developers addressed the bug by standardizing and increasing the RPC message size limitations for all clients.

Frax Finance founder Sam Kazemian introduced a proposal under the Frax Singularity Roadmap that unveils a new tokenomics model, focusing on activating a protocol fee switch to enhance value distribution to veFXS holders. The model entails enabling the fee switch, which directs 50% of the generated yield back to veFXS holders—the token granted for locking the native FXS token. The remaining 50% will be allocated to purchase Frax assets for pairing in the FXS Liquidity Engine (FLE). The proposal comes after the protocol achieved a 100% Collateral Ratio (CR). The roadmap also includes the Flox Blockspace Incentives, designed to incentivize user and developer engagement with the Fraxtal Layer 2 network.

Espresso Systems, a shared sequencing infrastructure provider, raised a $28 million Series B funding round led by a16z Crypto. Espresso Systems targets the issue of liquidity fragmentation within the multi-rollup ecosystem. The Espresso Sequencer is designed to facilitate atomic transactions across rollups. Espresso Systems plans to allocate the new funds towards expanding its team and launching the Espresso Sequencer to mainnet.

Rollup Improvement Proposal (RIP) 7212 has been successfully implemented on Polygon PoS mainnet as part of the Napoli Hardfork. Polygon is the first network to implement the standard. RIP-7212 introduces a new standard for secure and cost-effective signature verifications using the secp256r1 elliptic curve. The standard aims to improve account abstraction by significantly lowering the costs associated with signature verification, leveraging common technologies like WebAuthn. Polygon has further plans to incorporate more RIPs in future network upgrades. zkSync, Optimism, and Kakarot ZKEVM have also pledged to adopt RIP-7212.

Coinbase's Layer 2 rollup, Base, has postponed planned maintenance for testing the pausability features on its native bridge. The maintenance requires a temporary pause in withdrawals from the native bridge for about an hour. The update was pushed to March 27th at 11AM PST. The delay comes amid a surge in activty on the network. Base has seen over 1 million daily transactions over the past week. The influx in activity has caused the median gas fee on Base to increase from a few cents to upwards of a dollar. The network’s TVL has nearly doubled in the past month, making Base the fifth largest Layer 2 by TVL with $1.6 billion in locked assets.

DeFi Saver introduced a new feature that enables automatic debt repayment for loans on the CurveUSD lending protocol. The feature allows users to set a health ratio threshold and a crvUSD repayment amount to automatically trigger the loan repayment. The feature aims to avoid the risk of hard liquidations. This automated repayment will execute even if the funds available are below the configured amount. It will not execute if the required payback amount surpasses 50% of the transaction's gas costs. DeFi Saver also offers an automated leverage management tool for CurveUSD positions. DeFi Saver is a DeFi dashboard aggregator.

Nethermind released a post-mortem for its consensus bug on January 21st, which caused validators to incorrectly mark valid blocks as invalid. The bug led to validators going offline, missing out on block validations and attestations. The root of the issue was traced to a smart contract transaction containing a revert opcode that caused transactions to fail by using up all its gas, creating a discrepancy in the block hash and breaking network consensus. Nethermind says it plans to enforce stricter requirements for changes affecting EVM and consensus mechanisms.
