Scroll, an EVM-equivalent ZK rollup, manually increased its fee scalars by up to 1,280x, leading to significant overcharging its users for transaction fees. According to L2BEAT, it resulted in over $50,000 in excess fees charged. The scalars control how much users pay for L1 data, but fees were far higher than the underlying costs. Engineers from Succinct reported paying over $20 per transaction on the L2 network. The inflated fees coincided with ether.fi migrating its credit card infrastructure from Scroll to OP Mainnet. Although Scroll later reduced the scalars by 160x, fees still remain about 8x above baseline without a clear reason and no response from the Scroll team.
World Liberty Financial, an Ethereum-based DeFi platform by Donald Trump, deposited 5 billion WLFI tokens from its treasury as collateral to borrow $75 million, comprising $65 million in USD1 and $10 million in USDC, via the Dolomite lending protocol on Ethereum mainnet. Notably, Dolomite co-founder Corey Caplan is an adviser to World Liberty Financial, raising conflict-of-interest concerns. The large collateral deposits have driven utilization rates on Dolomite to peak levels, leaving many stablecoin depositors unable to withdraw their assets. Utilization has exceeded 80% in the USD1 pool and 90% in the USDC pool. Since WLFI has thin liquidity, a potential liquidation could result in bad debt for Dolomite and losses for regular depositors. World Liberty Financial has already transferred $40 million to Coinbase Prime, likely for off-ramping.
Ethereum Foundation public goods researcher Devansh Mehta proposed an in-protocol mechanism to redirect a portion of Ethereum staking rewards toward funding developer teams that improve the operator experience. The aim is to trade slightly lower validator yields for a stronger ecosystem and higher long-term ETH value. The proposal would be introduced in a hard fork and coordinated through the Ethereum Validators Association. Validators would signal their gas capacity, the share of rewards they're willing to redirect, and their preferred funding recipients. If a majority supports a redirect, the same contribution would be applied across all validators.
Zerion, a leading portfolio tracker and wallet provider, is advising users to temporarily avoid its web app while it investigates suspicious activity. As a precaution, it has taken the web app offline and blocked access using Blockaid to mitigate risk. Zerion confirmed that user funds remain safe, with only the web app affected. The iOS and Android apps, as well as the browser extension, continue to operate securely. Zerion later stated the attack is contained.

Polygon Labs, Frax, Curve Finance, and DFB have launched onchain foreign exchange (FX) liquidity pools on the Polygon PoS network, enabling fast, low-cost currency swaps. The pools use the frxUSD dollar-pegged stablecoin as the base asset. Initial pairs include the BRZ (Brazilian real), IDRX (Indonesian rupiah), tGBP (British pound), AUDF (Australian dollar), and KRWQ (Korean won). Curve Finance provides the trading infrastructure through its FXSwap pools, designed for low slippage and tight spreads, while DFB handles liquidity and market-making for non-USD stablecoin pairs. Together, the system enables near-instant settlement, lower fees, and transparent pricing, bringing FX markets onchain.
Linea, the EVM-equivalent ZK rollup developed by Consensys, improved the speed and efficiency of its proving system. The improvement comes from a redesign of its core architecture, replacing 252-bit "large fields" with much smaller 31-bit fields, which dramatically lowers computation costs. Although the Ethereum Virtual Machine operates on 256-bit numbers, Linea splits them into smaller chunks and processes them in parallel, taking advantage of modern CPUs that are optimized for efficient 32-bit operations. Linea also introduced zkASM, a flexible constraint-writing system that works across different field sizes, avoiding the need for a full rewrite of existing logic. Together, the improvements make proofs faster, cheaper, and more efficient, enabling faster withdrawals and better liquidity, lowering hardware requirements for developers, and reducing transaction fees for users.
Etherscan released a revamped smart contract tab on its block explorer, making it easier to explore and interact with contracts. The update introduces a full IDE-style code browser, letting developers navigate using a file tree, jump between functions with a contract outline, open multiple files in tabs, and search across all contract files. It also features improved Read/Write tabs with a cleaner interface for understanding and interacting with contract functions.

Paradigm released Reth 2.0, the latest version of its Ethereum execution node written in Rust, delivering 1.7 Ggas/s throughput on large blocks and a major storage reduction to around 240 GB for mainnet nodes. The release introduces an upgraded snapshot system, allowing users to download only the data they need. Architecture improvements in the release include parallel state calculation, with the Sparse Trie Cache enabling in-memory persistence across blocks and eliminating the state root as a bottleneck. The parallel execution is enabled through Ethereum Block Access Lists (BALs).
Polygon activated the Giugliano upgrade on its PoS network, delivering faster transaction finality, more predictable and transparent fees, and improved overall performance. Confirmation times have dropped to around 5 seconds, down from roughly 7 seconds. Gas fee parameters are now embedded directly in block headers, making it easier to estimate transaction costs. The upgrade also introduces enhancements such as improved block propagation, restored snap sync, and stronger Heimdall failover support. Giugliano is part of a series of recent upgrades pushing Polygon closer to its Gigagas goal, as it continues evolving into a platform optimized for payments.
Coinbase launched the Coinbase Developer Platform (CDP) CLI, a unified command-line tool for accessing payments, trading, wallets, custody, and onchain workflows. The CLI also doubles as a Model Context Protocol (MCP) server and agent skill, enabling AI agents to call Coinbase APIs directly without custom code. Built from an OpenAPI spec, the tool automatically incorporates new features, keeping both the CLI and agents up to date. CDP CLI effectively turns Coinbase's full crypto infrastructure into a single, AI-ready interface. The CLI simplifies development, automation, and agent interactions with onchain systems.
DeFi lending protocol Morpho launched Morpho Agents in beta, an AI-optimized interface designed for onchain lending. The platform enables AI agents to seamlessly integrate with Morpho, with full read, simulation, and write capabilities across Ethereum and Base. It also introduces a Builder Agent, a protocol knowledge base that equips AI coding agents to generate and verify Morpho integrations. The solution is aimed at enterprises, institutions, and developers building lending infrastructure.
