Networks and wallets for COMP to ARB
Ethereum mainnet (ERC-20 COMP)
Confirm the wallet holds transferable COMP. Compound v2 receipt tokens such as cETH or cDAI represent supplied assets, and unclaimed COMP rewards may need a separate claim before sending.
Arbitrum One (ERC-20 ARB)
Check that the receiving service credits ARB on Arbitrum One specifically. If you plan to send it onward from self-custody, leave some ETH on Arbitrum One for fees.
Check COMP deposit and ARB payout availability separately. The live service needs to accept your source network and offer the destination network that your ARB wallet expects.
How to convert COMP to ARB
- Enter the COMP amount to see the estimated ARB payout.
- Enter a receiving address on Arbitrum One · ERC-20 ARB and a refund address on Ethereum mainnet · ERC-20 COMP. Check any destination tag your wallet requires.
- When the route accepts orders, review the exact amounts and follow the deposit instructions. Submit the COMP transaction ID and use your private order link to track the ARB payout.
How to compare COMP to ARB rates
For a rough pre-fee estimate, multiply the COMP amount by the rate expressed in ARB per COMP. Then compare the actual ARB payout for the same COMP amount and network. Check whether the withdrawal fee comes out of what you send or is charged separately.
Swap Crypto has a $100 minimum. Estimates use market prices before fees. The order page shows the exact send and receive amounts, and your wallet may charge a separate network fee for sending the deposit.
