Once funds are in a ledger, accounts can transfer, swap, and earn yield while balances and activity stay off public block explorers. Only deposits and withdrawals touch Base — everything in between is private. See [Private Transactions](/get-started/private-transactions).

## What's exposed onchain

| Data      | Public? | Why                                       |
| --------- | ------- | ----------------------------------------- |
| Sender    | Hidden  | The transfer stays inside the ledger.     |
| Recipient | Hidden  | The transfer stays inside the ledger.     |
| Amount    | Hidden  | The transfer stays inside the ledger.     |
| Activity  | Hidden  | Nothing about the transfer lands on Base. |

The ledger stays agnostic to the offchain system behind it, so you run your own bookkeeping and custom transaction logic.
