###### **Verifiable Options:**

- `--verifiable` — Produce a SEP-58 verifiable (reproducible) build.

Snapshots the working tree into a byte-reproducible source archive, builds it in a digest-pinned container image, and records provenance meta (bldimg, source_uri, source_sha256, bldopt) into the wasm so a third party can reproduce the exact bytes. Implies `--locked`. Requires a clean git tree. When `--image` is omitted, a `docker.io/stellar/stellar-cli:<cli>-rust<rustc>` image is derived and pinned to its digest.

- `--source-sha256 <SOURCE_SHA256>` — Pin the SEP-58 source_sha256 of the generated archive (64-char lower-case hex). The build fails if the archive hashes to a different value
- `--source-uri <SOURCE_URI>` — Record a SEP-58 source_uri where the source archive can be fetched (a URI with a scheme, e.g. https://example.com/src.tar.gz)

## `stellar contract archive`

Generate the reproducible source archive used by verifiable builds

**Usage:** `stellar contract archive [OPTIONS]`

###### **Options:**

- `-o`, `--out-file <OUT_FILE>` — Where to write the gzipped tarball. Required unless `--dry-run` is used
- `--dry-run` — List the entries that would be archived and the computed source_sha256, without writing any file

## `stellar contract extend`

Extend the time to live ledger of a contract-data ledger entry.
