• Euler introduces EulerSwap.

• Ithaca launches Porto developer preview.

• Katana unveils its ZK DeFi Rollup.

• ZKsync introduces Prividium.

Euler Labs introduced EulerSwap, an AMM-based DEX that integrates Euler’s lending vaults with Uniswap v4’s hook architecture. It aims to solve capital inefficiencies by depositing LP assets into lending vaults, enabling leverage and additional yield generation. Stable assets can be reused across multiple shared liquidity pools. EulerSwap also features Just-in-Time (JIT) Liquidity, where LPs can borrow output tokens using input tokens as collateral. LPs can implement delta-neutral strategies and hedge impermanent loss. Unlike traditional AMMs, each pool is individually created and controlled by a single LP, offering full customization over AMM curves and pricing.  Euler will host a $50,000 rEUL builder competition.

Ithaca launched a developer preview of Porto, a pre-release of its TypeScript library that simplifies the integration of passwordless authentication, crypto payments, and account recovery into web, mobile, and desktop apps. Porto is live on Base Sepolia and will soon be available across all EVM-compatible chains. Designed with modularity and modern standards in mind, Porto supports EIP-7702, includes an EIP-1193 compatible provider, and integrates seamlessly with tools like Wagmi and Privy. It replaces traditional wallets and extensions with WebAuthn Passkeys and OAuth, making onboarding and transactions seamless. A bug bounty is currently live on Base Mainnet.

Katana unveiled its DeFi-focused, ZK-powered Layer 2 rollup, built with cross-chain interoperability through the Agglayer. By integrating Succinct’s validity proofs, Katana enables fast finality, low-cost proving, and nearly instant secure withdrawals. Katana aims to address idle crypto assets by offering deep liquidity and sustainable high yield for liquidity providers. Katana leverages sequencer fees and protocol-generated revenue to fund liquidity and reward active participation. The network incorporates chain-owned liquidity (CoL), an integration with the Agglayer’s Vaultbridge and vbTokens, and a native AUSD stablecoin. Pre-deposits are currently live, with the public mainnet launch expected in late June.
