With the launch of Citrea, Bitcoin's first ZK rollup, it's now possible to run full smart contracts, access DeFi protocols, borrow against BTC collateral, and interact with a growing ecosystem of on-chain applications, all secured by Bitcoin's base layer.
For active DeFi users chasing yield across the EVM landscape, Citrea is the next chain worth positioning on. But a new opportunity on a new chain means the same old problem: your USDC and USDT are already fragmented across multiple networks, and consolidating them onto Citrea the traditional way means a separate bridge transaction per chain, a network switch every time, and gas fees on every source chain before you've made a single trade.
FastBridge makes it simple. Bridge USDC, USDT, and other stablecoins to Citrea from multiple source chains in a single transaction, in seconds.
FastBridge is the fastest way to get stablecoins onto Citrea.
How FastBridge Gets You to Citrea in Seconds
FastBridge is a unified stablecoin bridge powered by Avail Nexus, an intent-based execution coordination layer. Instead of routing through chain-specific bridge contracts one at a time, FastBridge reads your stablecoin balances across all connected chains and lets you move them to Citrea in a single transaction.
You don't bridge from Ethereum first, then Arbitrum, then Base. You tell FastBridge where you want to end up, and how much you want to arrive with. FastBridge aggregates your balances, calculates the optimal routing, and executes in one step.
What this looks like in practice
- FastBridge reads your USDC and USDT balances across Ethereum, Arbitrum, Base, Avalanche, and all other connected chains simultaneously.
- You select Citrea as your destination and enter the amount you want to arrive with.
- FastBridge identifies the optimal combination of your multichain balances to fill the request in one transaction.
- You can deselect individual source chains from the balance breakdown if you want to control which chains you draw from – FastBridge recalculates in real time.
- You sign once. FastBridge handles the routing, gas management, and execution across all source chains.
- Your stablecoins land on Citrea in seconds, ready to interact with ₿apps, lending markets, DEXs, and the rest of the ecosystem.
What would normally be 3–4 separate bridge transactions, network switches, and 15–20 minutes of waiting becomes a single action. For a chain that's building a real-time DeFi ecosystem, that speed and convenience matters.
How to Bridge to Citrea: Step-by-Step
Step 1: Open FastBridge
Go to fastbridge.availproject.org in your browser. Connect your wallet (MetaMask, Rainbow, Coinbase Wallet, or any WalletConnect-compatible wallet). No download required.
Step 2: Select Citrea as your destination
In the destination chain selector, choose Citrea. FastBridge immediately scans your wallet and displays your stablecoin balances across all connected source chains in a single unified view.

Step 3: Set your amount and review your sources
Enter the total USDC or USDT you want to arrive with on Citrea. FastBridge calculates the optimal draw from your multi-chain balances automatically. If you'd prefer not to pull from a specific chain, for example, to preserve your balance on Base, you can deselect it using the checkboxes in the balance breakdown. FastBridge recalculates the routing instantly.

Step 4: Review the summary and confirm
FastBridge shows you a clear breakdown: which source chains will be used, how much will be drawn from each, total fees, and estimated arrival time. No hidden costs. When you're ready, just sign one transaction.
Step 5: Arrive on Citrea, ready to use ₿apps
Your stablecoins land on Citrea in seconds. You're immediately ready to deposit into a lending protocol, provide liquidity on a DEX, interact with a prediction market, or explore any other ₿app in the Citrea ecosystem, without additional steps.
Why FastBridge Is the Right Bridge for Citrea
New users onboarding to Citrea tend to have capital spread across the EVM ecosystem, on Ethereum, on L2s, in various protocols, and need to move stablecoins to Citrea efficiently to participate in its lending markets, DEXs, and yield opportunities.
FastBridge is purpose-built for exactly this: consolidating fragmented multi-chain stablecoin positions into a single destination chain, quickly, without the friction of manual multi-step bridging.
Bridge to Citrea from any chain, in real time, and experience DeFi on Bitcoin.
