# Options Library

As we are not currently running a frontend for Option Tokens or Options Liquidity Mining, the Options Library is intended to allow protocols to easily integrate these into their own frontends.

[GitHub](https://github.com/Bond-Protocol/options-library)

[NPM](https://www.npmjs.com/package/@bond-protocol/options-library)

The main benefits of this library are as follows:

* Helper functions for common frontend tasks such as calculating prices, APRs, requesting commonly used data on Option Tokens etc
* Getter functions for contract addresses/ABIs on a per chain basis (initially, these will all be identical, and ideally will stay that way. However, past experience with our Bond contracts shows that there is a possibility they may diverge later).

The library uses [Viem](https://viem.sh), and some helper functions require a Viem [`PublicClient`](https://viem.sh/docs/clients/public.html) or [`WalletClient`](https://viem.sh/docs/clients/wallet.html) (the Viem equivalent of [Ethers](https://ethers.org/)' [`Provider`](https://docs.ethers.org/v6/api/providers/) and [`Signer`](https://docs.ethers.org/v6/api/providers/#Signer)) to be passed in - this is easiest for frontends using [wagmi](https://wagmi.sh) v1+, but we have included an example UI using the legacy Ethers based version of wagmi in order to demonstrate manual setup of a `PublicClient` and `WalletClient`.
