ERC-7412

A standard for using oracle data on Ethereum

Build protocols that use data from oracles

Write and deploy smart contracts that call oracle contracts to reference off-chain data.

Example Code

function ethPrice() public view returns (uint256) {
  IPythERC7412Wrapper pyth = IPythERC7412Wrapper("0xEb38e347F24ea04ffA945a475BdD949E0c383A0F");
  bytes32 priceId = "0xff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace";
  uint stalenessTolerance = 60; // in seconds
  return pyth.getLatestPrice(priceId, stalenessTolerance); // also see getBenchmarkPrice()
}

Build apps with protocols that connect to oracles

The client library automatically adds oracle data to transactions when necessary.

View on GitHub View on npm

// Under Development

import { withRequiredOracleData, PythAdapter } from "erc7412";

// Call View Functions
// This automatically resolves `OracleDataRequired` and `FeeRequired` errors.
// TODO

// Prepare Transactions for Signing
// This returns an array that includes `fulfillOracleQuery()` calls when necessary.
const transactionsWithOracleData = await withRequiredOracleData(
  transactions,
  [new PythAdapter('https://hermes.pyth.network')]
);
return await client.sendTransactions({ transactions: transactionsWithOracleData });

See the full example using permissionless.js.

// Under Development

import { withRequiredOracleData, PythAdapter } from "erc7412";

// Call View Functions
// This automatically resolves `OracleDataRequired` and `FeeRequired` errors.
// TODO

// Prepare Transactions for Signing
// This returns a call to the trusted multicall forwarder.

See the full example using viem v2.

// Call View Functions

Compatible Account Abstraction Solutions

Protocols that integrate with the trusted multicall forwarder are also compatible with EOAs.
