Citrea is building toward a future where Bitcoin is more than a store of value; it’s a programmable layer for a new generation of applications. As Citrea goes live, it is unlocking a new class of Bitcoin applications from private transfers, payments, to trust-minimized yield and more.
The question for app builders isn’t what can be built, but how to launch these products with users and liquidity from day one. Avail empowers that.
Through this partnership, Avail enables Bitcoin applications launching on Citrea to be scalable, liquid, and multi-chain from day one.
Citrea is Defining the Next Gen of Apps on Bitcoin
Citrea is a Bitcoin ZK rollup purpose-built to extend Bitcoin from a passive settlement layer into an active foundation for a variety of financial and non-financial applications.
At its core, Citrea allows developers to build Bapps (Bitcoin applications) that execute with high performance while anchoring their security back to Bitcoin. Instead of overloading Bitcoin’s base layer, Citrea introduces a modular design where execution, data availability, and settlement are cleanly separated. This gives builders the freedom to scale throughput, optimize costs, and design richer applications, without breaking alignment with Bitcoin’s trust model.
Avail integration allows Citrea Bapps to scale and access global liquidity.
The Fastest Way To Onboard Liquidity & Users To New Citrea Bapps
Avail has integrated Nexus support for the Citrea mainnet, enabling Citrea Bapps to plug directly into liquidity from 14+ chains, including Ethereum, Base, Arbitrum, Hyperliquid, Kaia, and more.
For Bapp builders, this means:
You don’t need to wait for liquidity to migrate.You don’t need to design a bridge-first UX.You don’t need to rebuild distribution from scratch.
Simply unlock the NEXUS EFFECT. Tap into stablecoins, BTC liquidity, altcoins, and other assets and users that already live on Ethereum, and EVM rollups, while settling and executing on Citrea.
Builders can:
- Access liquidity across popular EVM chains while executing on Citrea.
- Enable cross-chain asset flows behind a single, app-native user experience
- Launch multichain-ready applications from day one, not months later.
Several Bapps, including Satsuma DEX, Zentra, KalqiX, and Crest, are already integrating the Nexus SDK to launch with a multichain user base from day one.
How to Onboard Liquidity & Users with Avail Nexus
Avail provides two core primitives that make this possible.
Embed Nexus SDK
Several Bapps launching alongside Citrea mainnet, including Crest and others, are already integrating the Nexus SDK into their Bapp. If you need any developer support, just get in touch.
Additionally, developers may customize ready-made React plug-and-play components for their cross-chain requirements using Avail Nexus Elements. Enabling deposits into your application from multiple cross-chain networks in one go opens up a plethora of opportunities!
Citrea Fast Bridge, powered by Avail Nexus.
Avail’s Citrea Fast Bridge allows users on Citrea to:
- Bridge aggregated balances to Citrea from 14+ ecosystems
- Experience a simple one-click transfer that only takes seconds to complete.
- Support for key assets, including USDC, USDT, and cBTC

With Citrea Fast Bridge and native support for cBTC and ctUSD, Bapps gain immediate access to capital flows to interact across the web3 ecosystem.
Avail DA for Citrea Bapps
Data availability shouldn’t be the bottleneck that limits your application’s growth. Citrea builders can choose Avail DA to access:
- Posting data efficiently with predictable costs and scalable throughput.
- 250 m/s preconfirmations provides instant response times for end users for a seamless app UX with Turbo DA.
- Infinity Devnet with 2 GB blocks and access to advanced configurations with an aggressive scaling roadmap (10GB blocks).
If you’re planning to deploy an L3 or Bapp using Avail for data availability, that path is ready today.
