Welcome to the Superchain Monthly Recap, a snapshot of the key updates and network-level progress across the Superchain over the past month.
April was a busy month across the Superchain, with new asset classes, regulated products, and mainstream consumer apps all finding their way onto OP Stack infrastructure. A lot of what landed this month would have looked unlikely a year ago.
Ronin Network is coming home to Ethereum on May 12th and using the OP Stack, after four years and millions of players onchain. It's one of the biggest gaming ecosystems in crypto choosing the OP Stack for its next chapter. Over on Celo, MiniPay is putting up $1M in CELO for Mini App builders, with payouts based on actual transaction activity rather than pitch decks. It's a clear signal about who the ecosystem wants to back: builders who are shipping and pulling in real users.
A full breakdown of Superchain activity is available at stats.optimism.io.
ether.fi, the largest non-custodial crypto card by spend volume, finished migrating to OP Mainnet in three days. No downtime, no user complaints, cards working the entire time. The move brought $220M in TVL, 70,000 active cards, and 300,000 accounts with it, making it the largest single TVL event in OP Mainnet history. The Optimism Foundation worked alongside the ether.fi team on bridge engineering, oracle support, and asset metadata to make it happen.
The product is what makes this matter. ether.fi Cash gives you tap-to-pay anywhere Visa runs, instant settlement, and yield on every dollar sitting in the account, which is something no traditional card can offer. For a payment product settling real money every day, the bar for infrastructure is high: median fees at $0.00001, sub-250ms finality via Flashblocks, 99.99% uptime, and throughput scaling toward 100Mgas/sec. OP Mainnet hit every one of those marks, which is why ether.fi picked it.
Six years after launching on Earth Day, Celo has become the most widely adopted blockchain for stablecoins in the world, with 1.27B+ lifetime transactions, 25 native stablecoins, and a consistent spot at the top of the L2 leaderboard by daily active users, peaking at 840K. For perspective, that's more people using the network in a single day than the entire population of San Francisco. The birthday came a week after the community unanimously approved CELOccelerate, the tokenomics upgrade that's already pushed network revenue up 66.6% with transaction costs still sub-cent.
MiniPay has been a huge part of that growth. The self-custodial stablecoin wallet built by Opera now has 14M+ users across 66 countries and has processed 400M+ stablecoin transactions on Celo alone. To mark the anniversary, MiniPay rolled out 16% cashback rewards for users buying CELO in the wallet, and Opera put up to $1M in CELO behind Mini App builders across the 50+ apps already integrated. Celo Core Co. and Opera also kicked off a MiniPay Roadshow in Ho Chi Minh City and Manila, with more stops coming across Southeast Asia and Latin America.
Sunnyside Labs, an Optimism core developer, launched Privacy Boost, a confidential computing module built natively on the OP Stack. It uses a ZK and TEE hybrid setup: ZK for cryptographic correctness and confidentiality, TEE for speed and integration simplicity, delivering sub-500ms proof generation at high throughput. The contracts are audited by OpenZeppelin. Compliance teams get selective disclosure through viewing keys, TRM Labs is integrated for sanctions screening, and the full audit view was designed with MiCA and BSA requirements in mind. For regulated companies that had ruled out public blockchains because of data exposure, that objection now has a real answer.
Privacy Boost is already moving across the Superchain. After launching on OP Mainnet, it deployed on Soneium and is now integrating directly into the Startale App as the chain's official privacy partner. The Startale App handles real balances, real payments, and card spending on Soneium, and Privacy Boost brings private balances, private transfers, and private card spending to that experience at consumer scale. It's one of the first real onchain privacy integrations in a mainstream consumer app, and a good preview of what's possible when core contributors ship real tools on the OP Stack.
Mitsui Launches Japan's First Commodity-Backed Cryptoasset on OP Mainnet
Mitsui, one of Japan's oldest and largest trading houses, launched Zipangcoin on OP Mainnet through Mitsui and Co. Digital Commodities. The product brings three tokens to the Superchain: ZPG for gold, ZPGAG for silver, and ZPGPT for platinum, each representing physical precious metals in a yield-bearing regulated instrument issued under Japan's crypto-forward regulatory regime. It's Zipangcoin's first time on a public blockchain, and it adds a new asset class to one of the most diverse ecosystems in crypto.
The reason OP Mainnet keeps getting picked is the same one playing out across the Superchain. The OP Stack powers 50+ chains in production, settled over $17 trillion in stablecoin volume in 2025, and handled 6 billion transactions that year alone. What's changing now is the mix of what's arriving: DeFi liquidity, consumer payments, and now a commodity-backed financial product from one of Japan's most established institutions. Different products, same infrastructure decision.
World ID 4.0 Goes Enterprise
World launched World ID 4.0, and proof of human is suddenly showing up everywhere. Tinder is using World ID in the US to give verified users a real-human badge. Docusign is using it so signers can prove they are human. Zoom is pairing it with video calls to verify that the person on screen isn't a deepfake. What was a crypto-native idea a year ago is now infrastructure that mainstream platforms are actively building into their core products.
The agentic web is pulling it in further. Vercel is using World ID for human-in-the-loop verification in AI workflows, and Okta is building a new Human Principal product with World ID at the center. This builds on AgentKit, which World and Coinbase launched in March to let verified humans delegate their World ID to AI agents. The pattern across all of it is the same: as agents become real economic actors online, the identity layer that tells humans and machines apart is becoming just as important as the payment layer underneath.
April showed the Superchain stretching into places it hasn't been before. A Japanese trading house bringing commodities onchain. A regulated crypto card migrating $220M without skipping a beat. Privacy infrastructure that finally answers compliance teams' biggest concern. Celo hitting six with usage numbers most chains can't touch. What's interesting isn't any one of these on its own, it's how different they are from each other and how naturally they all ended up on the same stack.
