 USDC on Base is a fully-backed digital dollar that settles in seconds and costs pennies in gas.  Base Pay lets you accept those dollars with a single click—no cards, no FX fees, no chargebacks.

-## Solidity's Builtin `transfer` function
-
-The `transfer` function is a built-in member of the `address` type in Solidity that can be used to send ETH to an address. Base Account wallets cannot receive ETH using this function.
-This function has long been considered deprecated in favor of `call` by the Solidity community, but some older contracts still use it.
-
-The reason for this is that `transfer` only forwards 2300 gas to the `transfer` call, a protective mechanism that was designed to prevent reentrancy attacks by limiting the amount of
-gas available to a smart contract that might reenter the caller.
-In the modern world of smart contract wallets (including for Base Account), this is often not enough gas for the smart contract's `receive` or `fallback` functions to complete their work,
-causing the transaction to revert.

 ### Known affected contracts
 
 - The [WETH9 contract](https://basescan.org/token/0x4200000000000000000000000000000000000006) uses `transfer` to send ETH to the user's wallet and therefore Base Accounts cannot directly unwrap ETH from it.
