Deploy 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, you will deploy a token registry smart contract on the Ethereum Sepolia network which is a test network that does not require actual ethers for transactions.

Prerequisites​

Deploying via OpenAttestation CLI​

Retrieving the private key​

Run the command:

 open-attestation wallet decrypt wallet.json

In the response, find the private key which looks like:

 - private key 0xd8f30c982fc23245a2cc4ec8271edcb4637f539d490ce750cdb5085241ffb41c

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 it with your private key):

d8f30c982fc23245a2cc4ec8271edcb4637f539d490ce750cdb5085241ffb41c

Important: Do not share this file with anyone else.

Deploying the token registry​

Replace the <registry-name> and <registry-symbol> below with a suitable name and symbol (usually three characters) and run the command:

open-attestation deploy token-registry <registry-name> <registry-symbol> -n sepolia -f key.txt

The following shows an example, in which <registry-name>="My Token Registry" and <registry-symbol>=MTR.

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

This will deploy the token registry on the Sepolia network.

When the deployment is successful, the response looks like the following:

ℹ  info      Deploying token registry My Token Registry
…  awaiting  Sending transaction to pool
…  awaiting  Waiting for transaction 0x7e3eea01c42bb10b3160f19c9f55fe3de24ed05abb9d6f4363c80c0d0f1be355 to be mined
✔  success   Token registry deployed at 0x8431012Bc040942B59e3C5bf428221eab0b2f723
ℹ  info      Find more details at https://sepolia.etherscan.io/address/0x8431012Bc040942B59e3C5bf428221eab0b2f723

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

Important: Save your token registry address for future reference.
