OpenAttestation (CLI)

This command line interface tool in the OpenAttestation CLI repository turns .json documents into OpenAttestation verifiable documents. It applies the OpenAttestation algorithm to produce a hash of the .json document, and then creates a file with the data and proof of integrity.

Installation

There are two ways to install the CLI, including binary and NPM. Additionally, you can use NPX to execute the code in the package directly.

Binary

To install the binary on your operating system, download the corresponding file from the CLI release page.

Note: There is an existing issue that the size of the binaries must be reduced, which is tracked in GitHub. If you want to contribute your feedback to resolve it, see this issue here.

NPM

If you are a Linux or MacOS user with npm installed on your machine, you can also install the CLI using the following command:

npm install -g @govtechsg/open-attestation-cli

The above command will install the open-attestation CLI to your machine. Be sure to have node.js installed, so that you can run the command.

NPX

If you only want to execute a few commands, you can also opt to use npx:

npx -p @govtechsg/open-attestation-cli open-attestation <arguments>

Upon installation, a configuration folder will be created at ~/.config/open-attestation/.

Important: The CLI is referred to as open-attestation when you run a command. The assumption is the CLI is available in your execution path. If not, you must change open-attestation to reflect the full path to the executable.

Adjusting preset gas price

To adjust transaction gas price, use the priority variable to scale against the market price.

Calculation: Priority * Previous block priority fee = Priority fee to use

The table below shows some examples:

Priority	Previous block priority fee	Priority fee to use
1	1	1 * 1 = 1
1.2	1	1.2 * 1 = 1.2
2	1	2 * 1 = 2
1	10	1 * 10 = 10
1.2	10	1.2 * 10 = 12
2	10	2 * 10 = 20

Fee information

To display an estimated price of a transaction, use the --dry-run option in your command.

The following shows a command example:

open-attestation deploy document-store "My Name" --network sepolia --dry-run

The response looks like:

Wrapping documents

The wrap command processes all documents in the input directory. It will add the issuance proofs to the individual documents. Additionally, you'll get the Batch Document Root (merkleRoot) value. Thereafter, you can issue all the documents in a single batch with the merkleRoot later.

The following shows a command example:

open-attestation wrap ./examples/raw-documents/example.0.json

The response looks like:

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

Specifying the output file while wrapping documents

The wrap command will display the result in the console. If you need to save the file, use the --output-file option in your command.

The following shows a command example with the --output-file option:

open-attestation wrap ./examples/raw-documents/example.0.json --output-file ./examples/wrapped-documents/example.0.json

The response looks like:

✔  success   Batch Document Root: 0x5d318c8083aac18f8075ca2a2eac74b06f2cc37d6ccad680c7c80c9bb36f7be1

Specifying the output directory while wrapping documents

If you need to wrap a folder, use the --output-dir option to specify in which folder all the documents will be wrapped.

The following shows a command example with the --output-dir option:

open-attestation wrap ./examples/raw-documents --output-dir ./examples/wrapped-documents

The response looks like:

✔  success   Batch Document Root: 0x5d318c8083aac18f8075ca2a2eac74b06f2cc37d6ccad680c7c80c9bb36f7be1

Providing an optional JSON schema while wrapping documents

You can also provide an optional JSON schema document using the --schema option to perform an extra check on the documents.

The following shows a command example with the --schema option:

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ --schema ./examples/schema.json

The response looks like:

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

Short form of the `--schema` option

Alternatively, you can use -s in the command, which is the short form of --schema.

open-attestation wrap ./examples/raw-documents/ ./examples/wrapped-documents/ -s ./examples/schema.json

The response looks like:

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

HTTP endpoint in the `--schema` option

The schema parameter also accepts a remote JSON schema.

The following shows a command example containing an HTTP endpoint:

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ --schema https://gist.githubusercontent.com/Nebulis/dd8198ab76443489e14121dad225d351/raw/693b50a1694942fb3cc6a8dcf5187cc7c75adb58/schema.json

HTTP endpoint in the short form `-s`

Similarly, you can also use the short form -s to replace the --schema option in the command:

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ -s https://gist.githubusercontent.com/Nebulis/dd8198ab76443489e14121dad225d351/raw/693b50a1694942fb3cc6a8dcf5187cc7c75adb58/schema.json

The response looks like:

✔  success  Batch Document Root: 0xf51030c5751a646284c898cff0f9d833c64a50d6f307b61f2c96c3c838b13bfc

Editing a wrapped document

You can also re-wrap a document through editing the wrapped document content and using the --unwrap option.

Run the command below to wrap a raw document:

open-attestation wrap ./examples/raw-documents/example.0.json --output-file ./examples/wrapped-documents/example.0.json

After the first round of wrapping, edit the content in the wrapped document. For example, change your name to another name in example.0.json.

To re-wrap the document after editing, run the command below with the --unwrap option:

open-attestation wrap ./examples/wrapped-documents/example.0.json --of ./examples/wrapped-documents/example.1.json --unwrap

Wrapping documents individually

You can disable the --batched option to wrap multiple documents individually. Consequently, these documents will not have the same merkle root.

The following shows a command example with the --batched option disabled:

open-attestation wrap ./examples/raw-documents/ --output-dir ./examples/wrapped-documents/ --batched false

The response looks like:

✔  success   All documents have been individually wrapped

Changing the OpenAttestation CLI version

By default, the CLI will use OpenAttestation schema V2, but you can opt in for OpenAttestation schema V3 using the --open-attestation-v3 option:

open-attestation wrap ./examples/raw-documents/ ./examples/wrapped-documents/ --open-attestation-v3

Alternatively, you can use the short form --oav3 to replace --open-attestation-v3 in the command:

open-attestation wrap ./examples/raw-documents/ ./examples/wrapped-documents/ --oav3

Note: Transferable Records must be wrapped individually as each of them will be minted to a unique title escrow that represents the document's beneficiary and holder entities. For more information about title escrow, see here.

Unwrapping documents

The unwrap command processes a wrapped document in the input directory. It will unwrap it to its raw document form, and display it in the console.

Wallet

You can create, encrypt, decrypt, or provide a wallet using the commands below.

Creating a wallet

The wallet create command creates a new wallet.

The following is a command example:

open-attestation wallet create --of ./tmp

The response looks like:

ℹ  info      Creating a new wallet
? Wallet password [hidden]
…  awaiting  Encrypting Wallet [====================] [100/100%]
ℹ  info      Wallet with public address 0x6348a96D96D56665C2E9619f81355918779f3d9E successfully created. Find more details:
✔  success   Wallet successfully saved into /path/to/tmp

Encrypting a wallet

Using the wallet encrypt command, you can encrypt a wallet.

Note: If you want to provide the wallet private key, see the "Providing the wallet" section.

The following is a command example:

open-attestation wallet encrypt --of ./tmp

The response looks like:

ℹ  info      Encrypting a wallet
? Wallet password [hidden]
…  awaiting  Encrypting Wallet [====================] [100/100%]
ℹ  info      Wallet with public address 0xB26B4941941C51a4885E5B7D3A1B861E54405f90 successfully created. Find more details:
✔  success   Wallet successfully saved into /path/to/tmp

Decrypting a wallet

The wallet decrypt command decrypts a wallet to get its information.

Important: Some information revealed by this command can be sensitive, e.g. the wallet private key.

The following is a command example:

open-attestation wallet decrypt wallet.json

The response looks like:

⚠  warning   You are about to reveal the private key of your wallet. Please type "yes" (without quotes) into the terminal to prove that you understand the risks
? ack: yes
ℹ  info      User consented to risks
? Wallet password [hidden]
…  awaiting  Decrypting Wallet [====================] [100/100%]
ℹ  info      Wallet successfully decrypted
✔  success   Wallet information:
- address: 0x19bf1b00f78f521999d9A4246818F362fcaA1A96
- public key: 0x04e1a6facd0fee89e44ae51c1352e32224e79caaa3ccf5afa9d77f10f92f7c4c584ccdf6cfb9a71584c18408a1a0e12341556757268117afebda00d6d6e71133bf
- private key ....

Providing the wallet

When interacting with blockchain, you need to provide a way to access your wallet. All functions that require this provide multiple ways for you to enter your wallet information:

It is recommended to use the --encrypted-wallet-path option where you provide a path to an encrypted wallet.
Use the OA_PRIVATE_KEY environment variable to hold the private key.
Use the --key-file option where you provide a path to a file containing the private key.
Use the --key option where you provide the private key directly to the command.

Important: When you use the --key option, the private key may be stored in the machine's bash history.

The following is a code example using the --encrypted-wallet-path option:

open-attestation deploy document-store "My Name" --network sepolia --encrypted-wallet-path /path/to/wallet.json

The response looks like:

# Then you will be prompted to type your password to decrypt the wallet
? Wallet password [input is hidden]

# Using environment variable
export OA_PRIVATE_KEY=0000000000000000000000000000000000000000000000000000000000000001
open-attestation deploy document-store "My Name" --network sepolia
unset OA_PRIVATE_KEY

# Using private key stored in file
echo -n 0000000000000000000000000000000000000000000000000000000000000002 >> ./examples/sample-key
open-attestation deploy document-store "My Name" --network sepolia --key-file ./examples/sample-key
rm ./examples/sample-key

# Providing the key to the command
open-attestation deploy document-store "My Name" --network sepolia --key 0000000000000000000000000000000000000000000000000000000000000003

Creating the configuration file

The config create command generates a configuration file named config.json with sandbox DNS, document store, and token registry.

Note: You need a wallet.json file with sufficient funds in the specified network for this command to work. Currently, OpenAttestation does not provide any faucet to dispense funds into wallet.json. You can search online for some faucets.

You can use the following options in this command:

--output-dir option specifies in which folder the configuration file will be created.
--encrypted-wallet-path option indicates a path to an encrypted wallet.
--config-template-url option provides a path to reference a configuration template file hosted on a public URL.
--config-template-path option provides a path to reference a config template file locally.

There are two ways of using this command to generate a configuration file. Both ways will return a new configuration file with the sandbox DNS, updated document store, and updated token registry.

Method 1: Using the `config-template-url` option (recommended)

These are the reference config templates:

Step 1. Make sure the wallet.json file has sufficient funds.

open-attestation wallet create --output-file wallet.json

Step 2. Generate the configuration file by providing the wallet.json file and a URL to the configuration file template.

open-attestation config create --output-dir ./example-configs --encrypted-wallet-path </path/to>/wallet.json

You need to provide certain information in the response:

// Please fill in the necessary information when prompted.
ℹ  info      Creating a new config file
? Wallet password [hidden]
? Using a config template URL? Yes
? Please enter the config template URL https://raw.githubusercontent.com/TradeTrust/tradetrust-config/master/build/reference/config-v2.json
? Select Network sepolia

Method 2: Using the `config-template-path` option

Step 1. Make sure the wallet.json file has sufficient funds.

open-attestation wallet create --output-file wallet.json

Step 2. Generate the configuration file by providing the wallet.json file and an existing configuration file.

open-attestation config create --output-dir ./example-configs --encrypted-wallet-path </path/to>/wallet.json

You need to provide certain information in the response:

// Please fill in the necessary information when prompted.
ℹ  info      Creating a new config file
? Wallet password [hidden]
? Using a config template URL? No
? Please enter the config template path </path/to>/config.json
? Select Network sepolia

Canceling a pending transaction

The transaction cancel command cancels a pending transaction.

Important: This action is irreversible.

You need to use the following options:

--nonce option specifies which transaction is to be canceled.
--gas-price option specifies the gas price, which is required to be higher than the pending transaction.
--transaction-hash option can be used as an alternative to the --nonce and --gas-price options. It will automatically increase the transaction gas price by 100%.
To learn more about the options for providing the wallet, see this GitHub readme.

The following is the command syntax:

open-attestation transaction cancel --nonce <pending transaction nonce> --gas-price <gas price> [option]

The following shows a command example with the --nonce option:

open-attestation transaction cancel --nonce 1 --gas-price 300 --network sepolia --encrypted-wallet-path /path/to/wallet

The following shows another example with the --transaction-hash option:

open-attestation transaction cancel --transaction-hash 0x000 --network sepolia --encrypted-wallet-path /path/to/wallet

Title escrow
