<Note>
  **Transaction types on Base:** Base supports Ethereum-standard types (`0x0` legacy, `0x1` EIP-2930, `0x2` EIP-1559) as well as Base deposit transactions (`0x7e`). Deposit transactions are injected by the sequencer at the start of each block. Fields like `maxFeePerGas`, `accessList`, and `chainId` are not present on `0x7e` transactions; instead they carry `sourceHash`, `mint`, `depositReceiptVersion`, and `yParity`.
