-# DID bnb typescript client
+# `did:bnb` Client
+
+A typescript client library for registering, manipulating, and resolving DIDs
+using the `did:bnb` method.
+
+## Features
+The `@identity.com/did-bnb-client` library provides the following features:
+
+1. A W3C [DID core spec (v1.0)](https://www.w3.org/TR/did-core/) compliant DID method and resolver operating on the Binance Smart Chain (BSC).
+2. TS Client for creating, manipulating, and resolving `did:bnb`.
+3. Generic Support for VerificationMethods of any Type and Key length.
+4. Native on-chain support for `EcdsaSecp256k1RecoveryMethod2020`.
+5. A web-service driver, compatible with [uniresolver.io](https://unresolver.io) and [uniregistrar.io](https://uniregistrar.io).
+6. Introduced `OWNERSHIP_PROOF` to indicate that a Verification Method Key signature was verified on-chain.
+7. Introduced `DID_DOC_HIDDEN` flag that enables hiding a Verification Method from the DID resolution.
+
+## Client library
+### Installation
+In the command line of the project folder, type the following and then press **Enter**:
+```shell
+yarn add @identity.com/did-bnb-client #
+```
+
+or
+
+```shell
+npm install @identity.com/did-bnb-client
+```
+
+### Contract Addresses
+The BNB DID Registry contract is deployed at the following address (via proxy):
+- Testnet: [0x88a05b4370BbB90c9F3EEa72A65c77131a7bc18d](https://testnet.bscscan.com/address/0x88a05b4370BbB90c9F3EEa72A65c77131a7bc18d)
+- Mainnet: TODO
+
+### Usage - Setup and Resolution
+Create a service for a `did:bnb` by using the following code snippet:
+
+#### Via Provider (read-only)
+```typescript
+const address = "0x88a05b4370BbB90c9F3EEa72A65c77131a7bc18d";
+const provider = getDefaultProvider(process.env.RPC_URL); // e.g. https://bsc-testnet.publicnode.com	
+const chainEnv: ChainEnviroment = 'tesnet';
+const didRegistry = new DidRegistry(provider, address, {chainEnvironment: 'localnet'});
+// ... use didRegistry client
+const randomDid = DidIdentifier.create(
+  Wallet.createRandom().address,
+  didRegistry.getDid().chainEnviroment
+);
+didRegistry.resolve(randomDid)
+    .then((didDocument) => {
+        console.log(didDocument);
+    })
+    .catch((error) => {
+        console.log(error);
+    });
+```
+
+#### Via Wallet
+```typescript
+    const address = "0x88a05b4370BbB90c9F3EEa72A65c77131a7bc18d";
+    const provider = getDefaultProvider(process.env.RPC_URL); // e.g. https://bsc-testnet.publicnode.com	
+    const randomWallet = Wallet.createRandom().connect(provider);
+    const chainEnv: ChainEnviroment = 'tesnet';
+    const didRegistry = new DidRegistry(randomWallet, address, {chainEnvironment: 'localnet'});
+    // ... use didRegistry client
+    // not passing a DID will resolve the DID of the wallet address
+    didRegistry.resolve()
+      .then((didDocument) => {
+        console.log(didDocument);
+      })
+      .catch((error) => {
+        console.log(error);
+      });
+```
+### DID resolution information
+`did:bnb` DIDs are resolved in the following way:
+1. `Generative` DIDs are DIDs that have no persisted DID account. (e.g. every valid EOA address is in this state).
+   This will return a generative DID document where only the public key of the Account is a valid Verification Method.
+2. `Persisted` DIDs are DIDs that have a persisted DID account. Here the DID document represents the state that is found
+   on-chain.
+
+### Check generative state (read-only)
+```typescript
+    // can optionally take a DIDIdentifier as a parameter 
+    const isGenerative: boolean = await didRegistry.isGenerativeDidState();
+```
+
+### Init a DID on-chain
+
+```typescript
+const tx: ContractTransaction = await didRegistry.initializeDidState();
+```
+
+### Add a VerificationMethod
+This operation adds a new Verification Method to the DID. The `keyData` can be a generically sized `UInt8Array`, but logically it must match the `methodType` specified.
+
+```typescript
+const verificationMethod = {
+   fragment: 'test',
+   flags: reduceVmFlagArray([
+      BitwiseVerificationMethodFlag.CapabilityInvocation,
+   ]),
+   methodType: VerificationMethodType.EcdsaSecp256k1RecoveryMethod2020,
+   keyData: utils.arrayify(Wallet.createRandom().address),
+};
+const tx: ContractTransaction = await didRegistry.addVerificationMethod(verificationMethod);
+```
+
+### Remove a VerificationMethod
+This code removes a Verification Method with the given `fragment` from the DID. It is important to keep at least one valid Verification Method with a Capability Invocation flag to prevent a lockout.
+
+```typescript
+const tx: ContractTransaction = await didRegistry.removeVerificationMethod('test');
+```
+
+### Add a Service
+This operation sets a new service on a DID. `serviceType` are strings, not enums, and can therefore be freely defined.
+
+```typescript
+   const service = {
+      fragment: 'test2',
+      service_type: 'testType',
+      service_endpoint: 'testEndpoint',
+   };
+   const tx: ContractTransaction = await didRegistry.addService(service);
+```
+
+### Remove a Service
+This operation removes a service with the given `fragment` name from the DID.
+
+```typescript
+  const tx: ContractTransaction = await didRegistry.removeService('test2');
+```
+
+### Set VerificationMethodFlags
+This sets/updates the flag on an existing VerificationMethod. **Important** if the flag contains `VerificationMethodFlags.OwnershipProof`
+this transaction MUST use the same authority as the Verification Method. (e.g. proving that the owner can sign with
+that specific VM).
+
+```typescript
+  const tx: ContractTransaction = await didRegistry
+        .setVerificationMethodFlags('test', [
+           BitwiseVerificationMethodFlag.Authentication,
+        ]);
+```
+
+### Add Native Controller (did:bnb - DID)
+```typescript
+   const randomWallet = Wallet.createRandom();
+   const nativeController = DidIdentifier.create(
+        randomWallet.address,
+        didRegistry.getDid().chainEnviroment
+   );
+   const tx: ContractTransaction = await didRegistry
+        .addNativeController(nativeController);
+```
+
+### Add External Controller (non-did:bnb DID)
+```typescript
+  const externalController = `did:ethr:${Wallet.createRandom().address}`;
+
+   const tx: ContractTransaction = await didRegistry
+           .addExternalController(externalController);
+```
 
 ## Local Integration Test Setup
-This repository uses `jest` to run integration test. These test will run against whatever `RPC_URL` is provided in the `.env` file.
+This repository uses `test:integration` to run integration test. These test will run against whatever `RPC_URL` is provided in the `.env` file.
 
-To run the integration test navigate to the `ts-client` directory and run `yarn jest`
+To run the integration test navigate to the `ts-client` directory and run `yarn run test:integration`.
 
 ### Testing with Foundry
 Foundry has a built in testnet node called `anvil`. You can first download foundry by following the [steps here](https://book.getfoundry.sh/getting-started/installation).
