Blast L2 Kit

npm

In an effort to bring more standardization and clarity to deploying on Blast L2, we've created this kit to help developers. Import directly into your project to use the Blast interfaces, or reference as a model for your own library. Includes interface for talking to Blast contracts and to configure points operator.

Installation

To install with Hardhat:

npm install blast-l2-kit

Contracts

The Solidity interfaces are located in the src directory.

src
├─ IBlast — "Interface for Blast yield contract"
├─ IBlastPoints — "Interface for Blast points operator"
├─ IERC20Rebasing — "Interface to change claim yield for ERC20 tokens (WETH & USDB)"
├─ IWETHRebasing — "Interface for converting WETH <-> ETH"
└─ examples/
   ├─ StandardAutomaticYield — "Setup for a contract with automatic yield"
   ├─ StandardClaimableYield — "Setup for a contract with claimable yield"
   ├─ UpgradeableAutomaticYield - "Setup for an upgradeable contract with automatic yield"
   ├─ ChangeYieldWethAndUsdb - "Example function for changing claim yield on WETH and USDB"
   └─ WETHRebasing - "Example on how to convert WETH <-> ETH"

Points Scripts

Within this repo is also a collection of scripts to check and distribute Blast Points. Reference the README there for more details.
