Bridge help without the guesswork.
Until support@circuswap.com is activated, the public Circuswap GitHub Issues page is the only official support channel.
Do not accept direct-message support, remote-access software, or a request to send tokens to “verify” your wallet.
Contact support
Open a public issue with the route direction, wallet type, failed step, and public transaction hash. Do not post personal information or wallet secrets.
Open a Circuswap support issue ↗Before opening an issue
- 1Do not restart after a successful burn
If the source burn succeeded, use Circuswap's “Resume failed transfer” action. Starting another bridge may create a second transfer.
- 2Check the correct source network
Use Ethereum Sepolia when bridging to Arc Testnet and Arc Testnet when bridging back to Sepolia.
- 3Keep gas available
Sepolia requires test ETH for gas. Arc Testnet uses USDC for gas, so Circuswap's MAX action keeps a small reserve.
Temporary Bridge recovery
Do not create another Base deposit merely because Circle finality is slow. Reopen the Temporary Bridge in the same browser tab/session, reconnect the same wallet, and refresh Circle finality. If Circle already returned a mint payload, retry the community relay or use self-mint only when that wallet has native Arc USDC for gas.
Save the Base fee transaction, Gateway deposit transaction, Circle transfer ID, and Arc mint transaction shown in the transfer record. Never post the EIP-712 signature or full attestation in a public support issue.
