# ERC-7412
ERC-7412 is the implementation of an Ethereum Improvement Proposal to provide a mechanism for loading data from a trusted provider on-chain, on-demand. Its a successor to the more constrained EIP-3668.
This repository contains a basic [reference implementation for a client library](./src/index.ts) enabling [ERC-7412](https://eips.ethereum.org/EIPS/eip-7412) support and a [test](./test/client.mjs) demonstrating its functionality.
Currently, there are 3 off-chain data providers officially supported. They are automatically loaded and processed by the library if observed:
- Pyth
- Chainlink
- Redstone
To learn more about using ERC-7412, see the [integration guide](./docs/integrate.md).
## Development Information
The library uses `pnpm`. The usual node.js project commands apply:
```
pnpm install
pnpm build
pnpm test
```
### Run the integration Test
A series of test scripts are included in the repository. For example, to run the Pyth test:
```
RPC_URL=... pnpm test:e2e:pyth
```
Other oracle provider may require credentials from the provider or other environment variables, depending on the provider.
