M10-SDK

The M10 (SDK) gives you access to the M10 APIs allowing you to build custom clients and banking integrations with the M10 Platform. Whether you are a central bank implementing custom applications, or a new Fintech who wants to build atop an M10 CBDC, the SDK is your first stop.

The M10-SDK is documented primary using TypeDoc (use yarn run docs to generate them) and examples in the tests.

Installation & Requirements

Run yarn install for a node version >16.

Using the SDK

Create an instance of the SDK and pass it the URL of your ledger Directory, specifying TLS:

const sdk = require("m10-sdk");

const ledgerUrl = "develop.m10.net";
const ledgerClient = new sdk.client.LedgerClient(ledgerUrl, true);

Setup signer based on the key:

const bankAdmin = "MC4CAQAwBQYDK2VwBCIEIIrikV/M3erX0lqmQgVXDRU1yFLStge7RyyvXv+kDesK";
const bankAdminSigner = sdk.signer.CryptoSigner.getSignerFromPkcs8V1(bankAdmin);

Make a request:

• Query request example which shows how to list accounts with bankAdmin as an owner:

  const request = { owner: bankAdminSigner.getPublicKey() };
  const response = await ledgerClient.listAccounts(bankAdminSigner, request);

• Transaction request example of creating an account:

  const { m10 } = require("m10-sdk/protobufs");
  
  const account = new m10.sdk.model.Account({
      id: utils.getUint8ArrayFromAccountId(accountId),
      name: "Name",
      publicName: "Some Public Name",
      owner: bankAdminSigner.getPublicKey(),
  });
  const transactionData = sdk.collections.getCreateTransactionDataFromDocument(
      m10.sdk.model.Account.encode(account).finish(),
      sdk.collections.Collection.Account,
  );
  
  const request = ledgerClient.transactionRequest(transactionData);
  const response = await ledgerClient.createTransaction(signer, request);

We also have some helpers, but it's better not to rely on them and use them only as an example to create your own.

Protobufs

Protobufs are generated using yarn run proto script, for this to work you need to have dependencies installed (yarn install) and have necessary proto files in ../../protobuf folder.

Tests

Tests are split into two parts:

• tests/integration will give you some examples on how to implement certain functionality
• tests/* are used for testing all actions separate without context

All of them can be run using yarn run test, or yarn run test:cover which will generate coverage reports (with html one saved in coverage folder).
