Hyperliquid

Switchboard supports HyperEVM with the same encoded-update flow used on other EVM chains. The current examples repo does not ship a dedicated Hyperliquid runner script, but you should reuse the evm/price-feeds contract and deployment flow with Hyperliquid-specific chain settings.

Network Information

Network	Chain ID	RPC URL	Switchboard Contract
Mainnet	999	https://rpc.hyperliquid.xyz/evm	0xcDb299Cb902D1E39F83F54c7725f54eDDa7F3347
Testnet	998	https://rpc.hyperliquid-testnet.xyz/evm	TBD

Quick Start

Clone the examples repo and build the shared price-consumer project:

git clone https://github.com/switchboard-xyz/sb-on-demand-examples.git
cd sb-on-demand-examples/evm/price-feeds
bun install
forge build

Deploy the consumer contract to HyperEVM with the packaged Foundry script:

SWITCHBOARD_ADDRESS=0xcDb299Cb902D1E39F83F54c7725f54eDDa7F3347 \
forge script deploy/DeploySwitchboardPriceConsumer.s.sol:DeploySwitchboardPriceConsumer \
  --rpc-url https://rpc.hyperliquid.xyz/evm \
  --private-key $PRIVATE_KEY \
  --broadcast \
  -vvvv

Integration Example

import { ethers } from "ethers";
import { CrossbarClient } from "@switchboard-xyz/common";

const provider = new ethers.JsonRpcProvider("https://rpc.hyperliquid.xyz/evm");
const signer = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);

const switchboard = new ethers.Contract(
  "0xcDb299Cb902D1E39F83F54c7725f54eDDa7F3347",
  ["function getFee(bytes[] calldata updates) external view returns (uint256)"],
  signer
);

const priceConsumer = new ethers.Contract(
  process.env.CONTRACT_ADDRESS!,
  ["function updatePrices(bytes[] calldata updates, bytes32[] calldata feedIds) external payable"],
  signer
);

const crossbar = new CrossbarClient("https://crossbar.switchboard.xyz");
const btcFeedHash = "0x4cd1cad962425681af07b9254b7d804de3ca3446fbfd1371bb258d2c75059812";

await crossbar.simulateFeed(btcFeedHash, false, undefined, "mainnet");

const response = await crossbar.fetchV2Update([btcFeedHash], {
  chain: "evm",
  network: "mainnet",
  use_timestamp: true,
});

if (!response.encoded) {
  throw new Error("Crossbar returned no encoded update payload");
}

const updates = [response.encoded];
const fee = await switchboard.getFee(updates);
const tx = await priceConsumer.updatePrices(updates, [btcFeedHash], { value: fee });
await tx.wait();

Notes

• The packaged evm/price-feeds/scripts/run.ts currently includes Monad presets, not Hyperliquid presets.

• For Hyperliquid, reuse the same contract and encoded-update flow shown above with chain ID 999.
