# Depositing Funds

## Deposit USDC 

Users need to deposit USDC into the protocol to use as collateral for trading or provide liquidity to the COMB Pool. 

Click "Deposit" on the top right corner to deposit USDC.

Users only need to make a transaction while depositing USDC, and no other transactions are needed while using Filament. This makes a better user experience, where they don't need to approve multiple transactions on each action on the protocol. <br>

**Note:** You might need to enter the token contract address manually for MetaMask to detect USDC.

**USDC Token Address:** 0x3894085Ef7Ff0f0aeDf52E2A2704928d1Ec074F1 \
\
**Note:** You will need some $SEI in your wallet to pay for gas fees when depositing funds, all other functions are gasless.&#x20;

Users can get some gas by using the faucet on the top navbar on the app.&#x20;
