Deploying Transferable Record Registry

The token registry is a smart contract on the Ethereum network that records the ownership information of a transferable record. It is compliant to the ERC721 standards.

In this guide, we will deploy a token registry smart contract on the Ethereum ropsten network which is a test network that does not require actual ethers for transactions.


Deploying via OpenAttestation CLI#

Creating the key file#

Create a file key.txt with the private key of your Ethereum wallet and save it in your working directory. If you are using Metamask, you may retrieve this key from the extension in this guide.

Sample key.txt file content (replace with your private key):


Do not share this file with anyone else!

Deploying the token registry#

Simply run the following command. You may replace the <registry-name> and <registry-symbol> with a suitable name and symbol (usually 3 characters).

open-attestation deploy token-registry "My Token Registry" MTR -n ropsten -f key.txt

This will deploy the token registry on the ropsten network. You should see a similar output when the deployment is successful:

ℹ info Deploying token registry My Token Registry

In this case, our contract has been successfully deployed on ropsten at the address 0x8431012Bc040942B59e3C5bf428221eab0b2f723.
