Terms of Use
These terms govern the Circuswap testnet bridge, live Arc token swaps, and the separately labeled experimental Temporary Bridge for real mainnet USDC.
1. The interface
Circuswap is an independent, non-custodial web interface that helps users submit crosschain USDC transactions through Circle App Kit and CCTP. Circuswap does not hold your assets, operate your wallet, possess your private keys, or guarantee that a third-party protocol will complete a transfer.
2. Testnet and temporary mainnet execution
The standard product executes on Ethereum Sepolia and Arc Testnet, where tokens have no monetary value. The standard mainnet bridge screen remains an inactive preview. The separately labeled Temporary Bridge may submit real Base-to-Arc mainnet USDC transactions through Circle Gateway and a Circuswap-operated mint relayer. It is experimental, one-way, unaudited, and may be suspended or fail without notice. The separately labeled Arc token swap route may execute when its provider rollout controls are enabled.
3. Fees
Circuswap adds a service fee equal to 2% of the bridge amount. The fee is charged in addition to the amount being bridged. Circle App Kit routes 90% of that custom fee to the fee-recipient address displayed in the transaction preview and documentation, and retains 10% for Arc. The CCTP Fast Transfer fee is separate and deducted from the bridge amount; network gas is also separate. Your wallet displays the final transaction details before you sign.
The Temporary Bridge instead deducts a 3% Circuswap service fee, a fixed 0.25 USDC temporary forwarding fee, and Circle's live Gateway maximum fee from the user's stated total spend. The temporary forwarding fee supports operating reserve and relayer availability but does not guarantee performance. Founding 500 credit does not apply to this temporary route.
4. Your responsibility
- Verify the network, token, destination wallet, amount, fee, and contracts.
- Maintain sufficient gas and secure your wallet credentials.
- Comply with laws that apply to you and your location.
- Do not use Circuswap for fraud, sanctions evasion, or unlawful activity.
Blockchain transactions may be irreversible. Circuswap cannot cancel, reverse, or recover a transaction you authorize.
4A. Arc token swaps
The Arc Swap MVP uses public token-discovery data and third-party V2 or V3 liquidity. Ranking, volume, price, liquidity, token names, and symbols can be inaccurate or manipulated. Inclusion is not verification, sponsorship, or an endorsement by Circuswap. You must verify the token contract, route, minimum received, approvals, and execution router before signing.
Tokens may be fraudulent, non-transferable, upgradeable, illiquid, subject to transfer taxes, or capable of losing all value. Quotes can change before a transaction confirms. The slippage limit does not protect against every smart contract, market, approval, or token risk.
4B. Circuswap Points
An eligible confirmed Arc swap may earn one Circuswap Point per USDC of verified input volume, including fractional amounts. Circuswap verifies the transaction against supported routers and records each transaction hash once. Rankings use total verified volume and may exclude transactions that cannot be validated.
Points are wallet-bound, non-transferable product records. They are not money, USDC, property, or a promise of a financial reward, and cannot be purchased, withdrawn, or transferred. Circuswap may correct fraudulent, duplicated, or technically erroneous entries and may change or discontinue the program.
5. Founding 500 credit
The first 500 unique wallet addresses whose valid Circuswap testnet bridge is received and verified by the registry may receive a $5 promotional ledger credit. Slots are assigned in verified-submission order, one allocation per wallet and per qualifying burn transaction. A credit is tied to that wallet, is not USDC or cash, cannot be withdrawn or transferred, and has no value unless Circuswap enables eligible mainnet bridge execution.
The credit may offset only Circuswap's 2% service fee. It does not cover, reimburse, or reduce Circle/CCTP protocol or forwarding fees, relayer fees, or network gas. The wallet remains responsible for all such third-party and network costs. Detailed verification and allocation rules appear on the Founding 500 page.
6. Third-party services
The interface depends on independent services including wallet software, RPC providers, Circle App Kit, CCTP, RadarDex's public data feed, decentralized exchange contracts, block explorers, and the underlying networks. Those services have their own terms, availability, risks, and security practices. Circuswap is not Circle, Arc Network, or an affiliated or endorsed product of either organization.
7. Risks and no warranty
The interface is provided “as is” and “as available.” Test networks may reset, fail, change contracts, or behave unexpectedly. Software bugs, wallet errors, network congestion, RPC failures, and third-party outages may interrupt a transfer. To the fullest extent permitted by law, Circuswap disclaims warranties and liability for losses arising from use of the interface.
Temporary Bridge risks additionally include Circle Gateway indexing delays, expiring BurnIntents, private-access policy changes, relayer service failure, Arc RPC failure, insufficient Arc gas for self-mint, and funds remaining in a Gateway balance until the user completes or recovers the route. Circuswap does not control Circle or Arc. Its relayer is best-effort, balance-limited, and provides no guarantee that a mint will be submitted or confirmed.
8. Changes and access
Circuswap may update, suspend, or discontinue functionality and may revise these terms as the project develops. Material changes will be reflected by the date at the top of this page. Continuing to use the interface after an update means you accept the revised terms.
9. Support
Use the official Support page. Circuswap support will never request your seed phrase, private key, or a transfer to a “verification” address.
