OP Enterprise is positioning itself as full-service infrastructure for teams running their own chain, covering the operating environment across 30+ dependencies — from security, data, and RPCs to compliance, oracles, bridges, and explorers. The approach means operators select from a partner ecosystem rather than build and run every piece of infrastructure themselves, with the broader partner catalogue highlighted alongside the announcement.

Whitechain is officially evolving from a standalone proof-of-authority L1 into an Ethereum L2 powered by the OP Stack, with its Whitechain Sepolia Testnet now live. The upgrade is another chain choosing the OP Stack.

Privacy Boost, which started as the first privacy SDK built for the OP Stack, now has a consumer-facing app. The Privacy Boost App lets users connect their wallet, shield their assets, and send privately without breaking compliance, extending the enterprise SDK to everyday users.

Native USDC and CCTP are now live on X Layer by OKX, enabling direct redemption through Circle with no bridging required. The launch gives PSPs, fintechs, AI agents, and DeFi apps on X Layer access to the world's largest regulated dollar stablecoin for collateral, payments, and other use cases, laying a foundation for institutional adoption.

The credit backend behind 70K+ ether.fi Cash cardholders is moving to a dedicated Aave V4 instance on OP Mainnet. Cardholders can now borrow against PAXG from Paxos, SPYx from XStocksFi, WBTC, ETH, and ETHFI without selling, with more collateral types expected as the integration expands.

The update coincides with the next generation of the ether.fi crypto neobank app, adding tokenized stocks and metals trading plus an integrated Aave market on Optimism that allows borrowing against a full portfolio.

MetaMask's Agent Wallet launched with OP Mainnet support, giving AI agents a wallet to transact on the network. With a median transaction fee of $0.00001, execution costs stay low even when agent strategies require dozens of transactions on OP Mainnet.

Ink is building a series of chain and asset-level upgrades across security and compliance to support global, 24/7 onchain capital markets, developed with Hypernative Labs, Chainlink, Aave, Forta, RedStone, Optimism, and other industry leaders. More detail is expected in the coming weeks.

World Chain will be the first production L2 streaming EIP-7928 block access lists inside every flashblock. The feature is live on Sepolia now, with mainnet arriving August 17, covering protocol design, execution model, benchmarks, and why streamed access lists matter for scaling.

DB Securities is partnering with Optimism to bring tokenized securities assets onchain, an uncommon move given Korea's tokenized securities market is built on permissioned distributed ledgers. The OP Stack lets the firm connect public and private infrastructure while still meeting Korea's distributed ledger requirements.

Bitpanda is building Vision Chain, a 24/7 programmable financial infrastructure chain, on the OP Stack through OP Enterprise in Europe. The move is part of a broader push for always-on financial infrastructure, with Real-World Asset tokenization noted at over $36B onchain, driven by Treasuries, MMFs, and other heavy financial instruments.
