+# Asset transfer secured agreement sample
+
+The asset transfer events sample demonstrates how to transfer a private asset between two organizations without publicly sharing data .
+
+## About the sample
+
+This sample includes smart contract and application code in multiple languages. This sample shows how Fabric features state based endorsement, private data, and access control to provide secured transactions.
+
+### Application
+
+Refer [Secured asset transfer in Fabric](https://hyperledger-fabric.readthedocs.io/en/latest/secured_asset_transfer/secured_private_asset_transfer_tutorial.html) for application details .
+
+### Smart Contract
+
+The smart contract (in folder `chaincode-go`) implements the following functions to support the application:
+
+- CreateAsset
+- ChangePublicDescription
+- AgreeToSell
+- AgreeToBuy
+- VerifyAssetProperties
+- TransferAsset
+- ReadAsset
+- GetAssetPrivateProperties
+- GetAssetSalesPrice
+- GetAssetBidPrice
+- QueryAssetSaleAgreements
+- QueryAssetBuyAgreements
+- QueryAssetHistory
+
+## Running the sample
+
+Like other samples, the Fabric test network is used to deploy and run this sample. Follow these steps in order:
+
+1. Create the test network and a channel (from the `test-network` folder).
+   ```
+   ./network.sh up createChannel -c mychannel -ca
+   ```
+
+1. Deploy the smart contract implementations.
+   ```
+   # To deploy the go chaincode implementation
+   ./network.sh deployCC -ccn secured -ccp ../asset-transfer-secured-agreement/chaincode-go/ -ccl go -ccep "OR('Org1MSP.peer','Org2MSP.peer')"
+   ```
+
+1. Run the application (from the `asset-transfer-secured-agreement` folder).
+   ```
+   # To run the Typescript sample application
+   cd application-gateway-typescript
+   npm install
+   npm start
+
+   # To run the Javascript sample application
+   cd application-gateway-javascript
+   node app.js
+   ```
+
+## Clean up
+
+When you are finished, you can bring down the test network (from the `test-network` folder). The command will remove all the nodes of the test network, and delete any ledger data that you created.
+
+```
+./network.sh down
+```
