Superseed, a DeFi-focused protocol built as an OP Stack Layer 2, has joined the Superchain. Superseed features a native collateralized debt position system called SuperCDP, which allows users to lock assets such as ETH, WBTC, and the Superseed token as collateral to mint and borrow the Superseed stablecoin. Superseed offers interest-free, self-repaying loans, funded by the protocol’s revenue streams such as sequencer profits. As part of the Superchain, Superseed will follow shared standards, shard upgrades, and contribute a portion of its sequencer revenue to the Optimism Collective. Superseed is currently live on testnet.

Securitize, the tokenization provider for BlackRock’s USD Institutional Digital Liquidity Fund (BUIDL), now supports USDC conversions for investments into the fund. The integration leverages Zero Hash to allow investors to maintain their entire investment process onchain. BlackRock's BUIDL Fund offers onchain access to U.S. Treasury bills, maintaining a stable $1 per token value and distributing monthly dividends. Since its launch in March 2024, BUIDL has facilitated over $550 million in issuance.

Offchain Labs released an update on the progress, vision, and future roadmap for Arbitrum Orbit, a tech stack designed for building customizable L2 and L3 chains. The team is focusing on expanding gas token options, bringing the Timeboost Transaction Ordering policy to mainnet, and implementing the Bounded Liquidity Delay Protocol (BoLD) to enhance decentralization and security. Additionally, Offchain Labs is developing Layer Leap, a feature that will allow users to transfer funds directly from Ethereum to L3 Orbit chains in a single transaction. Looking ahead, longer-term plans include native USDC support, fast withdrawals, chain mesh, and alternative client implementations. Most updates are expected to roll out gradually throughout 2025.

Towns launched its permissionless group chat app on Base, now available on both web and iOS. Positioned as an onchain alternative to Discord, Towns enables communities to create and control their own communication spaces. Key features include token-gated memberships, end-to-end encryption, and monetization options. The app is built on the River Protocol and uses Privy for embedded wallet onboarding.
