# Select by address
Keep only the transactions that touch a specific address and print them to standard output.
## Pipeline
```mermaid
flowchart LR
src[N2N source] --> f1[SplitBlock] --> f2[ParseCbor] --> f3[Select] --> sink[Stdout sink]
```
- **Source** — `N2N`: mainnet relay, starting from the `Point` in `[intersect]`.
- **Filters**
- `SplitBlock`: breaks each block into individual transactions.
- `ParseCbor`: decodes the raw transaction CBOR into structured records.
- `Select`: keeps only records matching the `predicate` address
(`skip_uncertain = true` drops records it cannot confidently evaluate).
- **Sink** — `Stdout`: prints the matching transactions.
See the [Select filter docs](../../docs/v2/filters/select.mdx).
