+# ar-io sdk
+
+The ar.io SDK provides functionality for interacting with the ar.io ecosystem of services (e.g. gateways and observers) and protocols (e.g. ArNS). It is available for both NodeJS and Web environments.
+
+
+## Prerequisites
+
+- `node>=v18.0.0`
+- `npm` or `yarn`
+
+## Installation
+
+```shell
+npm install @ar-io/sdk
+```
+
+or
+
+```shell
+yarn add @ar-io/sdk
+```
+
+## Quick Start
+
+```typescript
+import { ArIO } from '@ar-io/sdk';
+
+const arIO = new ArIO();
+const gateways = arIO.getGateways();
+
+// outputs:
+
+// {
+//   "QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ": {
+//     "end": 0,

+```
+
+## Usage
+
+The SDK is provided in both CommonJS and ESM formats and is compatible with bundlers such as Webpack, Rollup, and ESbuild. Utilize the appropriately named exports provided by this SDK's [package.json] based on your project's configuration. Refer to the [examples] directory to see how to use the SDK in various environments.
+
+### Web
+
+#### Bundlers (Webpack, Rollup, ESbuild, etc.)
+
+```javascript
+import { ArIO } from '@ar-io/sdk';
+
+// set up client
+const arIO = new ArIO();
+// fetch gateways
+const gateways = arIO.getGateways();
+```
+
+#### Browser
+
+```html
+<script type="module">
+  import { ArIO } from 'https://unpkg.com/@ar-io/sdk';
+
+  // set up client
+  const arIO = new ArIO();
+  // fetch gateways
+  const gateways = await arIO.getGateways();
+</script>
+```
+
+#### Node
+
+##### ESM (NodeNext)
+
+```javascript
+import { ArIO } from '@ar-io/sdk/node';
+
+// set up client
+const arIO = new ArIO();
+// fetch gateways
+const gateways = await arIO.getGateways();
+```
+
+##### CJS
+
+```javascript
+import { ArIO } from '@ar-io/sdk';
+
+// set up client
+const arIO = new ArIO();
+// fetch gateways
+const gateways = await arIO.getGateways();
+```
+
+## Typescript
+
+The SDK provides TypeScript types. When you import the SDK in a TypeScript project types are exported from `./lib/types/[node/web]/index.d.ts` and should be automatically recognized by package managers, offering benefits such as type-checking and autocompletion.
+
+## ArIO Contract
+
+### APIs
+
+#### `connect(signer)`
+
+Connects an `ArweaveSigner` or `ArConnectSigner` instance to the client for performing `writeInteraction` calls.
+Supported only on clients configured with a `WarpContract` instance.
+
+NOTE: if you have a client configured with a `RemoteContract` instance, it will be overriden with a `WarpContract` instance using the existing configuration of the `RemoteContract` instance when `connect` is executed.
+
+```typescript
+const arIO = new ArIO();
+
+const browserSigner = new ArConnectSigner(window.arweaveWallet);
+arIO.connect(browserSigner);
+
+const nodeSigner = new ArweaveSigner(JWK);
+arIO.connect(nodeSigner);
+```
+
+#### `getBalance({ address, evaluationOptions })`
+
+Retrieves the balance of the specified wallet address.
+
+```typescript
+const arIO = new ArIO();
+const balance = arIO.getBalance({
+  address: 'INSERT_WALLET_ADDRESS',
+});
+
+// outputs: 0
+```
+
+#### `getBalances({ evaluationOptions })`
+
+Retrieves the balances of the ArIO contract.
+
+<!--
+// ALM - A part of me wonders whether streaming JSON might be beneficial in the future
+// and if providing streaming versions of these APIs will scale nicely longer term, e.g.
+// arIO.streamBalances({ sortingCriteria: BALANCE_DESC });
+ -->
+
+```typescript
+const arIO = new ArIO();
+const balances = arIO.getBalances();
+
+// outputs:
+
+// {
+//   "-4xgjroXENKYhTWqrBo57HQwvDL51mMvSxJy6Y2Z_sA": 5000,
+//   "-7vXsQZQDk8TMDlpiSLy3CnLi5PDPlAaN2DaynORpck": 5000,
+//   "-9JU3W8g9nOAB1OrJQ8FxkaWCpv5slBET2HppTItbmk": 5000,
+//   ...
+// }
+```
+
+#### `getGateway({ address, evaluationOptions })`
+
+Retrieves a gateway's info by its staking wallet address.
+
+```typescript
+const arIO = new ArIO();

+
+### Custom Contracts
+
+The ArIO contract client class exposes APIs relevant to the ar.io contract. It can be configured to use any contract ID that adheres to the spec of the ar.io contract. In the default case, it will automatically build and utilize a contract data provider interface that is configured to point the the known mainnet contract ID at construction time. You can provide custom contract data provider or, alternatively, a `contractTxId` to the ArIO constructor to use a different, ar.io-spec-compatible contract.
+
+```typescript
+// provide a custom contractTxId to the client and default to remote evaluation
+const remoteCustomArIO = new ArIO({
+  contractTxId: 'TESTNET_CONTRACT_TX_ID',
+});
+
+// provide a custom contract to the client, and specify local evaluation using warp
+const localCustomArIO = new ArIO({
+  contract: new WarpContract<ArIOState>({
+    contractTxId: 'TESTNET_CONTRACT_TX_ID',
+  }),
+});
+
+// provide a custom contract to the client, and specify local evaluation using remote cache
+const remoteCacheCustomArIO = new ArIO({
+  contract: new RemoteContract<ArIOState>({
+    contractTxId: 'TESTNET_CONTRACT_TX_ID',
+  }),
+});
+```
+
+## Arweave Name Tokens (ANT's)
+
+The ANT contract client class exposes APIs relevant to compliant Arweave Name Token contracts. It can be configured to use any contract ID that adheres to the ANT contract spec. You must provide either a custom contract data provider or a contractTxId to the ANT class constructor to use.
+
+### APIs
+
+#### `connect(signer)`
+
+Connects an `ArweaveSigner` or `ArConnectSigner` instance to the client for performing `writeInteraction` calls.
+Supported only on clients configured with a `WarpContract` instance.
+
+NOTE: if you have a client configured with a `RemoteContract` instance, it will be overriden with a `WarpContract` instance using the existing configuration of the `RemoteContract` instance when `connect` is executed.
+
+```typescript
+const ant = new ANT();
+
+const browserSigner = new ArConnectSigner(window.arweaveWallet);
+ant.connect(browserSigner);
+
+const nodeSigner = new ArweaveSigner(JWK);
+ant.connect(nodeSigner);
+```
+
+#### `getOwner({ evaluationOptions })`
+
+Returns the owner of the configured ANT contract.
+
+```typescript
+const contractTxId = 'bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM';
+const ant = new ANT({ contractTxId });
+const owner = await ant.getOwner();

+
+#### `getControllers({ evaluationOptions })`
+
+Returns the controllers of the configured ANT contract.
+
+```typescript
+const contractTxId = 'bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM';
+const ant = new ANT({ contractTxId });
+const controllers = await ant.getControllers();
+
+// output: ["bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM"]
+```
+
+#### `getRecords({ evaluationOptions })`
+
+Returns all records on the configured ANT contract, including the required `@` record that resolve connected ArNS names.
+
+```typescript
+const contractTxId = 'bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM';
+const ant = new ANT({ contractTxId });
+const records = await ANT.getRecords();
+
+// output
+// {
+//     "@": {
+//       "transactionId": "nOXJjj_vk0Dc1yCgdWD8kti_1iHruGzLQLNNBHVpN0Y",
+//       "ttlSeconds": 3600
+//     },
+//     "cn": {

+//       "ttlSeconds": 3300
+//     }
+//   }
+```
+
+### Configuration
+
+ANT clients can be configured to use custom contract evaluator. By default they will use the remote evaluator that leverages the [arns-service].
+
+```typescript
+// provide a contractTxId to the client and default to remote evaluation
+const remoteANT = new ANT({
+  contractTxId: 'ANT_CONTRACT_TX_ID',
+});
+
+// provide a custom contract to the client, and specify local evaluation using warp
+const warpEvaluatedANT = new ANT({
+  contract: new WarpContract<ANTState>({
+    contractTxId: 'ANT_CONTRACT_TX_ID',
+  }),
+});
+
+// provide a custom contract to the client, and specify local evaluation using remote cache
+const remoteANTContract = new ANT({
+  contract: new RemoteContract<ANTState>({
+    contractTxId: 'ANT_CONTRACT_TX_ID',
+    // the remote api that returns warp compliant contract evaluation
+    url: 'https://api.arns.app/v1/contract',
+  }),
+});
+```
