1/ Appchains are becoming the go-to strategy for scaled platforms in fintech, gaming, and social.
Here’s why the corporate appchain era is already here—and who might be next 🧵
2/ An appchain is a dedicated blockchain built for a single product or ecosystem.
Instead of competing with thousands of other apps, companies can launch their own execution layer—usually secured by Ethereum.
3/ Thanks to Ethereum L2 frameworks like @arbitrum Orbit and @Optimism's OP Stack, spinning up an appchain is nearly plug-and-play.
You get Ethereum security + faster, cheaper, purpose-built infra.
@arbitrum @Optimism 4/ Appchains are ideal for scaled platforms handling millions of daily transactions or billions in value:
— Brokerages
— Payment processors
— Games & social networks
These platforms don’t need to find users. They already have them.
5/ Why Appchains Work
They unlock powerful advantages:
• Scalability – Own your blockspace. No congestion.
• Predictable costs – Subsidize or customize fees.
• Custom UX – KYC, geo-blocking, wallets, etc.
• MEV capture – Keep sequencer revenue in-house.
• Roadmap control – Ship on your schedule.
@arbitrum @Optimism 6/ They also plug into Ethereum’s liquidity and infrastructure, so users can easily move assets across chains.
You get custom infrastructure without fragmentation.
@arbitrum @Optimism 7/ But appchains aren’t free of tradeoffs:
• Security assumptions – Users trust the chain operator during challenge periods.
• Liquidity fragmentation – Requires bridges or shared sequencers.
• Infra overhead – Running provers, sequencers = ops load.
@arbitrum @Optimism 8/ The good news: appchain infra is maturing fast.
Tooling has evolved from “build it yourself” → “abstracted, modular stacks.”
Let’s break it down ⬇️
9/ Appchain Deployment Tools
- @Calderaxyz: L2/L3 on OP Stack, Arbitrum, etc. Custom gas, DA, Metalayer for liquidity.
- @conduitxyz: OP/Arbitrum rollups w/ hosting & analytics.
- @alt_layer: Restaked rollups for ZK/optimistic stacks.
10/ Cross-Chain Tools
- @LayerZero_Core: Omnichain messaging for assets/liquidity.
- @SOCKETProtocol: Abstraction for swaps/bridging.
- @lifiprotocol: Cross-chain DEX/bridge aggregator.
- @AcrossProtocol: Intents-based bridge for rollups.
- @Optimism Superchain: Shared security/comms.
- @Agglayer: ZK liquidity for CDK.
- @axelar: PoS messaging.
- @hyperlane: Permissionless for rollups.
11/ Wallet UX & Account Abstraction
- @privy_io: Embedded wallets with email/social logins.
- @biconomy: Gasless, paymasters, AA.
- @Web3Auth: MPC social logins.
12/ Dev Tools
- @thirdweb: SDKs & contracts for rollups.
- @Alchemy: L2 RPC/nodes.
- @TenderlyApp: Observability/debugging.
All of this lets teams focus on product—not plumbing.
@arbitrum @Optimism @Calderaxyz @conduitxyz @alt_layer @LayerZero_Core @SOCKETProtocol @lifiprotocol @AcrossProtocol @privy_io @biconomy @Web3Auth @thirdweb @Alchemy @TenderlyApp 13/ Already Happening:
@Coinbase launched Base in 2023 with OP Stack. Top L2, 14M+ txns/day. Powers wallet, payments, DeFi. Captures fees/MEV in-house.
@arbitrum @Optimism @Calderaxyz @conduitxyz @alt_layer @LayerZero_Core @SOCKETProtocol @lifiprotocol @AcrossProtocol @privy_io @biconomy @Web3Auth @thirdweb @Alchemy @TenderlyApp @coinbase 14/ @RobinhoodApp followed in 2025.
• Deployed tokenized US equities on Arbitrum.
• Announced Robinhood Chain via Orbit.
• 20M+ users on day one.
• 24/7 trading + real-time settlement.
They didn’t bootstrap users. They brought them.
@arbitrum @Optimism @Calderaxyz @conduitxyz @alt_layer @LayerZero_Core @SOCKETProtocol @lifiprotocol @AcrossProtocol @privy_io @biconomy @Web3Auth @thirdweb @Alchemy @TenderlyApp @coinbase @RobinhoodApp 15/ Who’s Next?
Any platform that owns users + transactions is a candidate:
— Fintech: PayPal, Stripe, Revolut, Block
— Gaming: Epic, Roblox, Unity
— Social: X, Discord, Reddit, Twitch
They don’t need liquidity—they are the liquidity.
@arbitrum @Optimism @Calderaxyz @conduitxyz @alt_layer @LayerZero_Core @SOCKETProtocol @lifiprotocol @AcrossProtocol @privy_io @biconomy @Web3Auth @thirdweb @Alchemy @TenderlyApp @coinbase @RobinhoodApp 16/ Appchains let these platforms turn infra into a monetizable asset—not a cost center.
The model works. The stack is ready. The distribution problem is solved.
@arbitrum @Optimism @Calderaxyz @conduitxyz @alt_layer @LayerZero_Core @SOCKETProtocol @lifiprotocol @AcrossProtocol @privy_io @biconomy @Web3Auth @thirdweb @Alchemy @TenderlyApp @coinbase @RobinhoodApp 17/ The corporate appchain era is here.
The only question left is: Who’s next?
@arbitrum @Optimism @Calderaxyz @conduitxyz @alt_layer @LayerZero_Core @SOCKETProtocol @lifiprotocol @AcrossProtocol @privy_io @biconomy @Web3Auth @thirdweb @Alchemy @TenderlyApp @coinbase @RobinhoodApp 17/ Thanks for reading! Subscribe and see the whole article here:
