Things to keep in mind, while using this library:
- There are implicit invariants these contracts expect to hold.
- You should exhaustively read each contract you plan to use, top to bottom.
- You can easily “shoot yourself in the foot” if you’re not careful with how you use the library.
The libraries have been developed under the following set of assumptions. Take a look at them here 🔗
Filecoin today lacks general programmability. As a result, it is not possible to deploy user-defined behaviour, or "smart contracts", to the blockchain. The goal of the FVM project is to add general programmability to the Filecoin blockchain. They predict this will unleash a proliferation of new services and tools that can be built and deployed to the Filecoin network, without requiring network upgrades, involvement from core implementation maintainers, changes in the embedded actors, or spec alterations.
It is a set of Solidity libraries that allow Solidity smart contracts to seamlessly call methods of Filecoin built-in actors. They do cross-platform calls to the real Filecoin built-in actors. A set of mock libraries are located too. They respond to specific scenarios based on the received parameters instead of doing real calls.
Querying an operating on the storage market, miner actors, verified registry for FIL+ automation, and more.

In order to use these APIs in your project, you will need to import them on your own contract. As they are embeddable libraries, they don't need to be present on the chain first. You can just import the library you desire and call its methods.
You will need to copy these files to a folder inside your project. Let's name it libs. In your smart contract, copy and paste these lines.
import { MarketAPI } from "./libs/MarketAPI.sol";
import { CommonTypes } from "./libs/types/CommonTypes.sol";
import { MarketTypes } from "./libs/types/MarketTypes.sol";
A better approach to import these libs is using the NPM package created for this. 🔗. Run on your project in order to add this package.
yarn add @zondax/filecoin-solidity
In your smart contract, copy and paste these lines.
import { MarketAPI } from "@zondax/filecoin-solidity/contracts/v0.8/MarketAPI.sol";
import { CommonTypes } from "@zondax/filecoin-solidity/contracts/v0.8/types/CommonTypes.sol";
import { MarketTypes } from "@zondax/filecoin-solidity/contracts/v0.8/types/MarketTypes.sol";
import { BigInt } from "@zondax/filecoin-solidity/contracts/v0.8/cbor/BigIntCbor.sol";
