-# Pyth EVM JS
-
-[Pyth](https://pyth.network/) provides real-time pricing data in a variety of asset classes, including cryptocurrency,
-equities, FX and commodities. This library allows you to use these real-time prices on EVM-based networks.
-
-## Installation
-
-### npm
-
-```
-$ npm install --save @pythnetwork/pyth-evm-js
-```
-
-### Yarn
-
-```
-$ yarn add @pythnetwork/pyth-evm-js
-```
-
-## Quickstart
-
-Pyth stores prices off-chain to minimize gas fees, which allows us to offer a wider selection of products and faster
-update times. See [On-Demand Updates](https://docs.pyth.network/documentation/pythnet-price-feeds/on-demand) for more
-information about this approach. In order to use Pyth prices on chain, they must be fetched from an off-chain Hermes
-instance. The `EvmPriceServiceConnection` class can be used to interact with these services, providing a way to fetch
-these prices directly in your code. The following example wraps an existing RPC provider and shows how to obtain Pyth
-prices and submit them to the network:
-
-```typescript
-const connection = new EvmPriceServiceConnection("https://hermes.pyth.network"); // See Hermes endpoints section below for other endpoints
-
-const priceIds = [
-  // You can find the ids of prices at https://pyth.network/developers/price-feed-ids#pyth-evm-stable
-  "0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43", // BTC/USD price id
-  "0xff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace", // ETH/USD price id
-];
-
-// In order to use Pyth prices in your protocol you need to submit the price update data to Pyth contract in your target
-// chain. `getPriceFeedsUpdateData` creates the update data which can be submitted to your contract. Then your contract should
-// call the Pyth Contract with this data.
-const priceUpdateData = await connection.getPriceFeedsUpdateData(priceIds);
-
-// If the user is paying the price update fee, you need to fetch it from the Pyth contract.
-// Please refer to https://docs.pyth.network/documentation/pythnet-price-feeds/on-demand#fees for more information.
-//
-// `pythContract` below is a web3.js contract; if you wish to use ethers, you need to change it accordingly.
-// You can find the Pyth interface ABI in @pythnetwork/pyth-sdk-solidity npm package.
-const updateFee = await pythContract.methods
-  .getUpdateFee(priceUpdateData)
-  .call();
-
-// Calling someContract method
-// `someContract` below is a web3.js contract; if you wish to use ethers, you need to change it accordingly.
-// Note: In Hedera you need to pass updateFee * 10^10 as value to the send method as there is an
-// inconsistency in the way the value is handled in Hedera RPC and the way it is handled on-chain.
-await someContract.methods
-  .doSomething(someArg, otherArg, priceUpdateData)
-  .send({ value: updateFee });
-```
-
-`SomeContract` looks like so:
-
-```solidity
-pragma solidity ^0.8.0;
-
-import "@pythnetwork/pyth-sdk-solidity/IPyth.sol";
-import "@pythnetwork/pyth-sdk-solidity/PythStructs.sol";
-
-contract SomeContract {
-  IPyth pyth;
-
-  constructor(address pythContract) {
-    pyth = IPyth(pythContract);
-  }
-
-  function doSomething(
-    uint someArg,
-    string memory otherArg,
-    bytes[] calldata priceUpdateData
-  ) public payable {
-    // Update the prices to be set to the latest values
-    uint fee = pyth.getUpdateFee(priceUpdateData);
-    pyth.updatePriceFeeds{ value: fee }(priceUpdateData);
-
-    // Doing other things that uses prices
-    bytes32 priceId = 0xf9c0172ba10dfa4d19088d94f5bf61d3b54d5bd7483a322a982e1373ee8ea31b;
-    // Get the price if it is not older than 10 seconds from the current time.
-    PythStructs.Price price = pyth.getPriceNoOlderThan(priceId, 10);
-  }
-}
-
-```
-
-We strongly recommend reading our guide which explains [how to work with Pyth price feeds](https://docs.pyth.network/documentation/pythnet-price-feeds/best-practices).
-
-### Off-chain prices
-
-Many applications additionally need to display Pyth prices off-chain, for example, in their frontend application.
-The `EvmPriceServiceConnection` provides two different ways to fetch the current Pyth price.
-The code blocks below assume that the `connection` and `priceIds` objects have been initialized as shown above.
-The first method is a single-shot query:
-
-```typescript
-// `getLatestPriceFeeds` returns a `PriceFeed` for each price id. It contains all information about a price and has
-// utility functions to get the current and exponentially-weighted moving average price, and other functionality.
-const priceFeeds = await connection.getLatestPriceFeeds(priceIds);
-// Get the price if it is not older than 60 seconds from the current time.
-console.log(priceFeeds[0].getPriceNoOlderThan(60)); // Price { conf: '1234', expo: -8, price: '12345678' }
-// Get the exponentially-weighted moving average price if it is not older than 60 seconds from the current time.
-console.log(priceFeeds[1].getEmaPriceNoOlderThan(60));
-```
-
-The object also supports a streaming websocket connection that allows you to subscribe to every new price update for a given feed.
-This method is useful if you want to show continuously updating real-time prices in your frontend:
-
-```typescript
-// Subscribe to the price feeds given by `priceId`. The callback will be invoked every time the requested feed
-// gets a price update.
-connection.subscribePriceFeedUpdates(priceIds, (priceFeed) => {
-  console.log(
-    `Received update for ${priceFeed.id}: ${priceFeed.getPriceNoOlderThan(60)}`
-  );
-});
-
-// When using the subscription, make sure to close the websocket upon termination to finish the process gracefully.
-setTimeout(() => {
-  connection.closeWebSocket();
-}, 60000);
-```
-
-### Examples
-
-There are two examples in [examples](./src/examples/).
-
-#### EvmPriceServiceClient
-
-[This example](./src/examples/EvmPriceServiceClient.ts) fetches `PriceFeed` updates using both a HTTP-request API and a streaming websocket API. You can run it with `npm run example-client`. A full command that prints BTC and ETH price feeds, in the testnet network, looks like so:
-
-```bash
-npm run example-client -- \
-  --endpoint https://hermes.pyth.network \
-  --price-ids \
-    0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43 \
-    0xff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace
-```
-
-#### EvmRelay
-
-[This example](./src/examples/EvmRelay.ts) shows how to update prices on an EVM network. It does the following:
-
-1. Gets update data to update given price feeds.
-2. Calls the pyth contract with the update data.
-3. Submits it to the network and prints the txhash if successful.
-
-You can run this example with `npm run example-relay`. A full command that updates BTC and ETH prices on the BNB Chain
-testnet network looks like so:
-
-```bash
-npm run example-relay -- \
-  --network "https://data-seed-prebsc-1-s1.binance.org:8545" \
-  --pyth-contract "0x5744Cbf430D99456a0A8771208b674F27f8EF0Fb"\
-  --mnemonic "my good mnemonic" \
-  --endpoint https://hermes.pyth.network \
-  --price-ids \
-    "0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43" \
-    "0xff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace"
-```
-
-## Hermes endpoints
-
-Pyth offers a free public endpoint at [https://hermes.pyth.network](https://hermes.pyth.network). However, it is
-recommended to obtain a private endpoint from one of the Hermes RPC providers for more reliability. You can find more
-information about Hermes RPC providers
-[here](https://docs.pyth.network/documentation/pythnet-price-feeds/hermes#public-endpoint).
