+# @canton-network/core-test-token
+
+A minimal, self-contained test token that implements the Canton Network Token
+Standard (CIP-56). It exists so wallet and dApp flows can be exercised end-to-end
+against a real registry-backed token without depending on Amulet.
+
+Exports:
+
+- **Main export** - TypeScript codegen bindings for the `splice-test-token-v1`
+  DAML package (`Splice`, `packageId`) plus small command builders
+  (`buildCreateTokenRulesCommand`, `buildMintTokenCommand`).
+- **`./registry`** - `startTestTokenRegistry()`, an HTTP server that creates the
+  token's `TokenRules` contracts and serves the four Token Standard off-ledger
+  registry APIs (metadata, transfer-instruction, allocation-instruction,
+  allocation). Once started, the token looks like any other CIP-56 token, with an
+  admin party and a registry URL.
+- **`./setup`** - helpers to locate and read the compiled
+  `splice-test-token-v1` DAR (`TEST_TOKEN_V1_DAR_PATH`, `readTestTokenV1Dar`) so
+  callers can vet it on their synchronizers.
