Moving assets between blockchains is straightforward. Preventing that movement from exposing more financial data than necessary is harder.
Most bridges execute transactions publicly. Anyone following the transfer may be able to see the source wallet, destination wallet, amount, timing and wider transaction history connected to both addresses.
Houdini Swap supports Arc from day one, giving users access to cross-chain routes through one interface. Depending on the selected assets and networks, users can choose between Private Swap, No Wallet Connect and Onchain DEX.

What is Arc?
Arc is an open, EVM-compatible Layer 1 blockchain developed by Circle for stablecoin payments and financial applications.
Arc uses USDC as its native gas token. Users pay network fees in USDC rather than a separate asset such as ETH.
According to the Arc mainnet announcement, the network provides predictable stablecoin fees, deterministic sub-second settlement finality and interoperability with more than 20 blockchains through Circle CCTP and Gateway.
The privacy problem with most cross-chain bridges
A public bridge moves assets between networks, but it does not hide the transaction trail.
If assets leave one wallet and arrive at another through a traceable route, blockchain analytics can potentially connect the two addresses. That link may expose balances, previous transfers, counterparties and future activity.
The bridge completed its job. The user also created a permanent public record connecting both sides of the transaction.
This matters for individuals protecting their financial data, businesses paying suppliers and teams managing treasury wallets. Public blockchains make settlement verifiable, but not every financial relationship needs to be visible to everyone.
Three ways to bridge to Arc with Houdini Swap
Houdini Swap provides different routing options based on how the user wants to complete the transaction.
Private Swap
Private Swap is designed for users who want to reduce the direct on-chain connection between their sending and receiving wallets.
Rather than creating an obvious wallet-to-wallet trail, the transaction is routed through Houdini Swap’s integrated exchange infrastructure. Private Swaps are screened for compliance while limiting the financial data exposed publicly.
Private does not mean invisible or outside compliance requirements. It means reducing the direct public link between the wallets used on each side of the swap.
Private Swap availability depends on the selected assets and networks. Check the live quote to confirm whether a private route to or from Arc is available for the chosen pair.
No Wallet Connect
No Wallet Connect allows users to swap without connecting their wallet to the Houdini Swap interface.
The user enters a receiving address and sends the source asset from their preferred wallet or platform. This removes the need to grant a website permission to interact with the wallet.
No Wallet Connect and Private Swap solve different problems. No Wallet Connect reduces wallet connection and approval exposure. It does not automatically make a transaction private or remove its public on-chain trail.
Route availability depends on the selected source asset, destination asset and network.
Onchain DEX
Houdini Swap’s Onchain DEX queries more than 20 decentralized exchanges, bridges and liquidity sources.
Users connect a wallet, select the source asset and choose Arc as the destination. Houdini Swap then presents an available route based on current protocol support and liquidity.
Onchain DEX routes are non-custodial but public. Wallet addresses and asset movements remain visible on-chain.
How to bridge crypto to Arc with Houdini Swap
1. Open Houdini Swap
Go to the Houdini Swap app.
2. Choose how you want to swap
Select the product that matches your requirements:
- Use Private Swap when reducing the public link between wallets is the priority.
- Use No Wallet Connect when you do not want to connect a wallet to the interface.
- Use Onchain DEX to search public, wallet-connected routes across supported protocols.
3. Select the source asset and network
Choose the asset you currently hold and the blockchain it is on.
Make sure the selected source network matches the network from which the funds will be sent.
4. Select Arc as the destination
Choose Arc as the destination network and select the asset you want to receive.
Available routes depend on the source network, asset pair, liquidity and current protocol support.
5. Enter the receiving address
Confirm the Arc wallet address that should receive the assets.
Check the address carefully. Blockchain transactions cannot normally be reversed after they are submitted.
6. Review the route
Before proceeding, check:
- The source and destination networks
- The input and output assets
- Expected output
- Network and protocol fees
- Slippage or price impact
- Estimated completion time
- Whether the route is public or private
The live quote is the source of truth for that transaction. Routes and expected output can change with liquidity, network activity and market prices.
7. Complete the swap
Follow the instructions shown for the selected route.
For an Onchain DEX route, connect a wallet and sign the required approvals and transactions.
For No Wallet Connect, send the required asset and amount to the address provided for the swap.
For a Private Swap, follow the deposit and receiving instructions presented by Houdini Swap.
Keep the swap ID or transaction hash until the transfer is complete.
Private Swap compared with Arc’s planned privacy
Houdini Swap’s Private Swap and Arc’s planned privacy system address privacy at different layers.
Private Swap focuses on the transaction route. It is designed to reduce the direct public link between the sending and receiving wallets.
Arc Privacy Sector is a planned network-level system for applications and smart contracts operating on Arc. Arc’s privacy documentation states that these features are on the roadmap and not yet available.
Until network-level privacy is available, standard Arc transactions remain publicly visible. A normal bridge or No Wallet Connect route should therefore be treated as public unless Houdini Swap explicitly identifies it as a Private Swap.

How much does it cost to bridge to Arc?
There is no fixed fee for bridging to Arc.
The total cost can include:
- Source-network gas
- Bridge or exchange fees
- Token approval gas
- Slippage
- Price impact
- Private routing fees, where applicable
A lower advertised fee does not always produce the highest final output. Compare the amount being sent with the amount expected on Arc.
What token is used for gas on Arc?
Arc uses USDC as its native gas token.
Users need USDC in their Arc wallet to submit transactions, interact with applications or move assets back out of the network.
More information is available in Arc’s documentation on its stablecoin-native model.
Bridge to Arc without exposing more than necessary
A bridge should move assets between networks. It does not need to expose every financial connection or require unnecessary wallet permissions.
Houdini Swap gives users one interface for finding routes to and from Arc, with Private Swap, No Wallet Connect and Onchain DEX available for supported asset and network combinations.

FAQs
Can I bridge to Arc privately?
Houdini Swap offers Private Swap for supported assets and networks. Check the live quote to confirm whether a private Arc route is available for the selected pair.
Can I bridge to Arc without connecting my wallet?
No Wallet Connect allows users to complete supported swaps without connecting a wallet to the Houdini Swap interface. The user enters a receiving address and sends the required asset from a wallet or platform of their choice.
Does No Wallet Connect make the transaction private?
Not by itself. No Wallet Connect removes the need to connect a wallet to the interface, but the transaction may still be publicly visible on-chain. Use Private Swap when reducing the direct wallet-to-wallet link is the priority.
Are standard Arc bridge transactions private?
No. Standard bridge and Onchain DEX transactions are publicly recorded. Wallet addresses, amounts and asset movements may be visible through block explorers and blockchain analytics tools.
How does Houdini Swap make a swap more private?
Private Swap is designed to reduce the direct on-chain link between the sending and receiving wallets. This limits the transaction data publicly connecting both sides of the swap.
Is Houdini Swap a crypto mixer?
No. Houdini Swap is a non-custodial, privacy-focused swap platform. Private Swaps are routed through integrated exchange infrastructure and screened for compliance.
Is Houdini Swap an Arc bridge?
Houdini Swap is a cross-chain aggregator rather than a single bridge. It searches supported exchanges, bridges and liquidity sources for available routes to and from Arc.
Does Arc use USDC for gas?
Yes. Arc uses USDC as its native gas token, so users need USDC to pay network fees.
Can I bridge assets out of Arc?
Yes, when a supported outbound route is available. Select Arc as the source network, choose the destination chain and review the available routing options.
