In short: Arc provides the stablecoin-focused network, while RocketX provides a cross-chain access layer for users who need to move liquidity from other supported networks into Arc.
Introduction
Arc Mainnet is now live, introducing a new Layer-1 blockchain built for stablecoin-native finance, real-time money movement, financial markets, and emerging use cases such as agentic economic activity. Developed by Circle, Arc uses USDC as its native gas asset, is EVM-compatible, and is designed to deliver deterministic sub-second settlement finality.
But launching a new blockchain also raises an important question for existing crypto users: How do you move your assets from networks like Ethereum, Solana, Robinhood Chain, BNB Chain, Base, and others to Arc?
RocketX provides cross-chain access to Arc from 200+ supported networks, allowing users to start with assets they already hold and swap them into supported destination assets on Arc through aggregated cross-chain routes.
In this guide, we’ll cover what Arc Mainnet is, why USDC is central to the network, how RocketX supports Arc from day one, which assets you can move to Arc, how to complete a cross-chain swap to Arc, Arc Mainnet’s key network details, and the common mistakes to avoid when moving assets to the new network. We’ll also explain how RocketX differs from a traditional bridge and answer the most common questions about accessing Arc.
Whether you’re holding BTC, ETH, SOL, USDC, or other supported assets, this guide will show you how to access the Arc ecosystem from the networks you already use.
What Is Arc Mainnet?
Arc is an open Layer-1 blockchain developed by Circle and purpose-built for stablecoin finance and internet-native financial applications.
Unlike general-purpose blockchains that rely on a volatile native token for transaction fees, Arc uses USDC as its native gas asset. This gives applications and users a dollar-denominated way to pay network fees while keeping the network focused on financial use cases.
Circle has designed Arc around several financial infrastructure requirements, including predictable fees, fast settlement, foreign exchange, stablecoin payments, tokenized assets, and programmable financial applications. Arc is also EVM-compatible, allowing developers to use familiar Ethereum tooling and frameworks.

Why Move Crypto to Arc?
The launch of a new blockchain creates a familiar liquidity problem. A user may hold BTC on Bitcoin, ETH on Ethereum, SOL on Solana, or USDC on another network. But the asset they hold is not necessarily the asset they need on Arc.
Traditionally, moving funds can require several separate actions:
Swap → Find a compatible bridge → Bridge → Wait for settlement → Swap again
That process can introduce additional fees, transactions, interfaces, and opportunities for mistakes.
Arc is designed around stablecoin-based financial activity, so access to the network’s liquidity becomes particularly important as its ecosystem grows.
Instead of asking:
“Which bridge supports the asset I already own?”
A more useful question is:
“How can I move the asset I already have into the asset I need on Arc?”
That is where an aggregated cross-chain route can simplify the process.
How RocketX Connects Users to Arc
RocketX is a non-custodial cross-chain exchange aggregator that connects liquidity across multiple centralized and decentralized exchanges and blockchain networks.
With Arc support, users can select their source network and asset, choose Arc as the destination, and let RocketX determine an available route.
For example:
ETH on Ethereum → USDC on Arc
or
USDC on Base → USDC on Arc
The exact assets and routes available depend on current liquidity and supported networks.
RocketX does not require users to deposit funds into a custodial account. The user connects a wallet, reviews the available route, and confirms the transaction from the wallet.

The important distinction is that RocketX should not be thought of as another single-purpose bridge. It acts as a liquidity aggregation layer, finding available cross-chain routes across its supported ecosystem.
What Can You Move to Arc?
With RocketX supporting Arc Mainnet from day one, users can move assets from major blockchain ecosystems directly into Arc through supported cross-chain routes.
Whether you hold USDC, ETH, BTC, or SOL, RocketX lets you select the asset you own, choose Arc as the destination network, and complete the swap through a single non-custodial flow.
Here are some of the key routes available:
USDC to Arc
Move USDC from Ethereum and other supported networks to Arc Mainnet through RocketX.
This route is particularly relevant to the Arc ecosystem because USDC is Arc’s native gas asset, allowing users to arrive on the network with the asset they can use for both financial applications and transaction fees.
ETH to Arc
Users holding ETH on Ethereum and other supported networks can swap ETH to an asset on Arc through RocketX without having to manually complete a separate swap and bridge transaction.
RocketX handles the cross-chain routing, allowing users to move from the asset they already hold toward their desired destination asset on Arc.
BTC to Arc
Bitcoin holders can move BTC to Arc through RocketX, combining cross-chain asset movement and conversion within the same swap flow.
This gives BTC holders a direct way to access Arc without first needing to manually move their BTC through multiple platforms.
SOL to Arc
Users holding SOL on Solana can also move their assets to Arc through RocketX using the supported cross-chain route.
This makes Arc accessible not only to Ethereum users but also to liquidity originating from the Solana ecosystem.
More Than a Single Asset Route
These routes demonstrate an important part of RocketX’s Arc integration: users don’t need to start with USDC just because Arc uses USDC as its native gas asset. They can start with assets such as BTC, ETH, SOL, USDC, and other supported cryptocurrencies, and RocketX can route the swap into the required destination asset on Arc.
The exact amount received, fees, and execution time are determined by the live route and liquidity available when the swap is initiated.
How to Bridge Crypto to Arc With RocketX
Moving crypto to Arc through RocketX follows a straightforward wallet-based process.
Step 1: Connect Your Wallet
Open RocketX and connect a supported wallet. There is no requirement to create a traditional exchange account.
Step 2: Select Your Source Asset
Choose the blockchain and asset you currently hold.
For example:
Ethereum → ETH
or
Solana → SOL
Step 3: Select Arc as the Destination
Choose Arc Mainnet as your destination network. Then select the asset you want to receive on Arc, such as USDC, where the route is supported.
Step 4: Review Available Routes
RocketX can display available routing options based on current liquidity. Depending on the route, users may see options optimized around:
- Best rate
- Fastest execution
- Private routing
Review the expected amount, network fees, route details, and estimated completion time before continuing.
Step 5: Confirm the Transaction
Once you select a route, confirm the transaction directly from your connected wallet. RocketX does not take custody of your funds during the process. After the transaction completes, the destination asset should arrive on the selected Arc address.
Arc Network Details
Arc is EVM-compatible, making it compatible with familiar Ethereum-style development and wallet infrastructure. Circle’s published Arc materials identify USDC as the network’s native gas asset and describe deterministic sub-second settlement finality.
For the mainnet network parameters, Chain ID 5042 is currently documented across Arc ecosystem infrastructure. Because RPC and explorer endpoints can change during a mainnet launch, users should use the current network details published by Arc rather than copying an RPC endpoint from an unofficial source.

Important: Do not confuse Arc Mainnet with Arc Testnet. The testnet uses a different Chain ID, 5042002, and separate RPC infrastructure.
Why USDC Matters on Arc
USDC is more than just another supported token on Arc. It is the network’s native gas asset, meaning users pay transaction fees in USDC rather than requiring a separate network token such as ETH.
This design is particularly relevant to financial applications.
Imagine a payment application that needs to send stablecoins but also needs a separate volatile asset to pay transaction fees. That creates an additional operational requirement.
Arc’s model is different:
Stablecoin balance → Transaction → USDC-denominated network fee
This is one of the fundamental design choices that differentiates Arc from many general-purpose networks.
What Can You Do on Arc?
Arc is designed around financial applications rather than a single narrow use case.
Circle describes the network as infrastructure for:
- Stablecoin payments
- Foreign exchange
- Financial markets
- Tokenized assets
- Real-time money movement
- Programmable finance
- Agentic economic activity
Arc’s architecture also includes integrations with Circle’s broader platform and is designed to remain open and composable for developers.
As the ecosystem expands, users may interact with payment applications, DeFi protocols, tokenized assets, trading applications, and other financial infrastructure built on Arc.
Common Mistakes When Moving Crypto to Arc
1. Confusing Arc Mainnet With Arc Testnet
Arc Testnet and Arc Mainnet use different network configurations.
Always verify that you are interacting with Arc Mainnet when moving real assets.
2. Sending the Wrong Asset
Selecting Arc as the destination does not automatically mean every source asset can be delivered directly. Check the destination asset and route before confirming.
3. Ignoring the Route Details
The displayed amount is not the only thing to consider. Review the expected output, network fees, execution time, and routing path before signing.
4. Assuming Every Token Is Supported
Cross-chain support depends on available liquidity and integrations. If a particular token or route is unavailable, RocketX may not be able to execute that exact transaction.
5. Using an Unofficial RPC
When manually adding a newly launched network to a wallet, use network parameters from Arc’s official documentation or your wallet’s verified network list. Avoid copying RPC URLs from random posts, comments, or unknown websites.

Arc Mainnet brings a new approach to on-chain financial infrastructure, with USDC as its native gas asset, EVM compatibility, fast settlement, and a focus on stablecoin-powered financial applications.
But a new blockchain needs more than its own infrastructure. It also needs liquidity and accessible entry points from the wider crypto ecosystem.
That’s where RocketX connects the two.
With Arc support available from day one, RocketX enables users to move assets from Bitcoin, Ethereum, Solana, BNB Chain, Base, and 200+ other supported networks into the Arc ecosystem through cross-chain swap routes.
You don’t need to start with USDC, manually search for a compatible bridge, or move between multiple platforms.
Connect your wallet → Select the asset you hold → Choose Arc → Review the route → Swap.
As the Arc ecosystem develops, connecting its stablecoin-focused financial infrastructure with liquidity from across the broader crypto market will become increasingly important. RocketX provides that cross-chain access layer, making it easier for users to move from the networks and assets they already use into Arc.
