+# Cosmwasm contracts e2e tests
+
+## Guideline
+
+Run local node
+
+```bash
+bash scripts/run-node.sh
+```
+
+Download the cw20_base wasm file
+
+```bash
+bash scripts/wasm/get_contract.sh
+```
+
+Then test upload code
+
+```bash
+bash scripts/wasm/upload_code.sh
+```
+
+After upload, we can test instantiate the cw20_code
+
+```bash
+bash scripts/wasm/instantiate_cw20.sh
+```
