Overview

The SDK wraps the TrustVault GraphQL interface and gives you easy access to core functionalities within the API.

The API can be configured against sandbox (ETH ropsten, BTC testnet3) or production environments.

If you use the SDK with an external instruction key the SDK provides callbacks for you to sign the correct data.

The SDK includes helper methods to ensure you data integrity including validating policy template, publicKey provenance, HMAC webhook payload and digests. It also includes an AWS KMS wrapper class for data signing.

The SDK requires an API key, please contact Trustology to get one.

See TrustVault Node.js SDK in github

Sign callback

The function that will be called with the data that needs to be signed.

AWS KMS wrapper class (AwsKmsKeyStore)

AwsKmsKeyStore class ensures that the correct key from the correct curve is used for signing. It has a method sign which is an implementation of the signCallback.

You will need to ensure that your code has the relevant AWS permissions to access your KMS key.

Get list of subWallets

Retrieve the list of subWallets associated with the API key. Use this method to get the subWalletId of the wallet you wish to create transactions from or get the walletId where the subWallets belongs to.

1

const subWallets = await trustVault.getSubWallets();

Send a bitcoin transaction to TrustVault

1

const requestId = await trustVault.sendBitcoin(fromSubWalletId, toAddress, amount, speed, signCallback);

Send an Ethereum Transaction

Send an ethereum transaction to TrustVault

1

const requestId = await trustVault.sendEthereum(fromAddress, toAddress, amount, asset, speed, currency, signCallback)

Changing the external instruction key of a wallet

Change the external public instruction key of a wallet

1

const requestId = await trustVault.replacePublicKeyInDefaultSchedule(walletId, publicKey, signCallback);

TrustVault.validateWebhookSignature(req.body, "<YOUR_WEBHOOK_SECRET>", req.headers["X-Sha2-Signature"]);
const webhookMessage = JSON.parse(req.body);
const requestId = await trustVault.signAndSubmitSignature(webhookMessage, signCallback);

NOTE: validateWebhookSignature is a static method

Create a new Bitcoin Address
