Flare periphery package for smart contract development

This package contains a collection of smart contracts deployed on the Flare, Coston2 (test network for Flare), Songbird and Coston (test network for Songbird) networks.

The intention of this package is to provide a set of interfaces for easier integration and development of smart contracts on Flare based networks.
Interfaces in the most recent version of this package are the same as the ones deployed on the networks. This package exposes all public and most of the internal interfaces but does not expose any of the implementations. If you want to access the implementations, you can use the official Flare smart contracts repo.

The package functions similar to openzeppelin library packages and can easily be imported in nodejs based projects as well as directly in remix IDE.

Basic familiarity with the Flare network and EVM is assumed for use. For more information, please refer to the Flare Developer Hub. If you want a guided tutorial on EVM development and Flare focused smart contract development with this package, see the guide on Getting Started with Flare.

Package structure

Each of the networks has its own folder and subfolders for interfaces of specific flare based technologies. The folder structure is as follows:

Example usages

$3

You should use IFtsoRegistry (or IIFtsoRegistry) for simple price queries or
IFtso (or IIFtso) for more advanced queries.
The IFtsoRegistry interface is available in
contracts/userInterfaces/IFtsoRegistry.sol and the
IFtso interface is available in contracts/userInterfaces/IFtso.sol.

To use the interfaces deployed on Flare network, just import them in your contract source:

`solidity
import { IPriceSubmitter } from "@flarenetwork/flare-periphery-contracts/flare/ftso/userInterfaces/IPriceSubmitter.sol";
import { IFtsoRegistry } from "@flarenetwork/flare-periphery-contracts/flare/ftso/userInterfaces/IFtsoRegistry.sol";
`

If you are using Foundry, you can install the interfaces with Forge and import them in your contract source:

`solidity
import { IPriceSubmitter } from "flare-periphery-contracts/flare/ftso/userInterfaces/IPriceSubmitter.sol";
import { IFtsoRegistry } from "flare-periphery-contracts/flare/ftso/userInterfaces/IFtsoRegistry.sol";
`

Very simple contract that can consume the FTSO prices is shown in examples/networkName/SimpleFtsoExample.sol.

An example usage of the FTSO system to dynamically price token in a contract is showcased in
examples/network/DynamicToken.sol` with a more detailed explanation in the blogpost.
