# Get Funds

> Fund an address on Base — withdraw from a Coinbase account, bridge from another chain, or use a testnet faucet.

You need a small amount of ETH on Base to pay for gas, plus whatever assets your app uses (USDC is the most common). How you fund depends on where your assets are.

## Mainnet

* **From a Coinbase account** — withdraw ETH or USDC and select **Base** as the network. Often the fastest path, no bridge required.
* **From another chain** — see [Bridge to Base](/base-chain/network-information/ecosystem-bridges) for routes from Ethereum, Solana, and Bitcoin.

## Testnet (Base Sepolia)

* Get free test ETH and USDC from the [Base faucets](/base-chain/network-information/network-faucets).
* Test USDC is also available from the [Circle faucet](https://faucet.circle.com) — select **Base Sepolia**.
