Supported networks
The Bancoli Web 3 Wallet supports USDC transfers on the following EVM-compatible blockchain networks:
Network | Chain ID | Block explorer | Gas sponsored by |
|---|---|---|---|
Base | 8453 | Coinbase Developer Platform | |
Optimism | 10 | Alchemy | |
Ethereum | 1 | Alchemy | |
Arbitrum | 42161 | Alchemy | |

Network | Reason |
|---|---|
Avalanche | Gas sponsorship is not yet available through our infrastructure provider. This may be added in a future release. |
Estimated settlement times
Settlement times represent how long it takes for a transaction to be fully confirmed (finalized) on-chain:
Network | Estimated time |
|---|---|
Base | ~12–15 minutes |
Optimism | ~12–15 minutes |
Ethereum | ~12–15 minutes |
Arbitrum | ~12–15 minutes |
Polygon | ~5 seconds |
Polygon is significantly faster because it uses a different consensus mechanism with near-instant finality.
Supported browser wallets
When depositing USDC into your Bancoli wallet from a browser extension, the following wallets are supported:
Browser wallet | Supported |
|---|---|
Rabby Wallet | ✅ |
Trust Wallet | ✅ |
Coinbase Wallet | ✅ |
MetaMask | ✅ |
To deposit via a browser wallet:
Open your Web 3 Wallet in Bancoli and click Deposit
Select your browser wallet from the list
Connect and confirm the transfer
If your browser wallet is not in the list above, you can still send USDC to your Bancoli wallet address manually from any wallet that supports EVM networks — just copy your wallet address or scan the QR code.
Gas fees
All gas fees are sponsored by Bancoli. You pay $0 to send or receive USDC through the Web 3 Wallet. Only outgoing transactions are gas-sponsored — incoming transactions do not require gas sponsorship on the recipient's side.
