 ## Unreleased
 
+### Fixed
+
+- `@midnight-ntwrk/ledger-v8` is pinned to 8.1.0, the exact version `midnight-js-protocol` 4.1.1 requires, so an npm install of the package holds one ledger copy. With 8.1.2 a second copy was nested and every deploy failed with `expected instance of DustParameters`. yarn and pnpm users add the resolutions listed in the README's "Supported stack" section (#171)
+
 ### Added
 
 - Initial package. `Deployer` and `runDeploy` build and submit a Compact deploy transaction from a `compact.toml` profile, resolving the artifact, constructor args, initial private state, and contract signing key, then record the result in `<deployments_dir>/<network>.json` (#86)
 - Wallet support: seed-file / `MN_DEPLOYER_SEED` / keystore / prefunded-local seed resolution, a per-seed on-disk sync cache under `.states/`, and a `proof_server = "auto"` mode that boots a testkit-js proof-server container for the run (#86)
-- Supported deploy stack is `@midnight-ntwrk/compact-runtime` 0.16.0 and `@midnight-ntwrk/ledger-v8` 8.1.2; artifacts must be compiled with `compact compile +0.31.1`. See the README's "Supported stack" section (#86)

 - A packaged `proof-server.yml`, pinning `midnightntwrk/proof-server:8.0.3`, is what `proof_server = "auto"` boots. `auto` no longer depends on a compose file in the working directory, though one there still wins (#165)

+`ledger-v8` is pinned to 8.1.0 because `midnight-js-protocol` 4.1.1 requires exactly that version. A second copy of the ledger WASM in the tree fails a deploy with `expected instance of DustParameters`. npm dedupes to the single pinned copy on its own. yarn and pnpm resolve each range to the newest version, so a project using them adds the same pins as this repo's root `package.json`:

 Compile with the pinned compiler: `compact compile +0.31.1`. The current default compactc (0.34.x) emits code for compact-runtime 0.19.0, and the deploy then fails with a `Version mismatch` runtime error.
 
 - As of 2026-09, `OpenZeppelin/compact-contracts` `main` is on compact-runtime 0.19.0 / ledger-v9 1.0.0-rc.3, so contracts built there are not deployable with this tool today.
