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 Improves Prover Speed --------------------------- Linea, the EVM-equivalent ZK rollup developed by Consensys, [improved](https://linea.build/blog/small-fields-faster-proving-on-linea-toward-real-time-finality) 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 Redesigns Contract Interface -------------------------------------- Etherscan [released](https://x.com/etherscan/status/2042215592640565650) 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.
