 > A first stab at the konduit cli
 
+## Workspace 
+
+- [ ] cardano-tx-builder - Pure cardano transaction builder utils 
+- [ ] cardano-connect - Traits for cardano connector
+- [ ] cardano-connect-blockfrost - Impl for blockfrost
+- [ ] konduit-core - Pure konduit transaction builders.
+    Depends only on cardano-tx-builder.
+    - [ ] test round trip data
+    - [ ] compiles to wasm
+- [ ] konduit-cli - cli wrapping of core
+
 ## TODOs 
 
 - [x] serde for relevant data
