layer2

zklink core contract, EVM compatible.

A 100% opensource CLI that goes along with building blocks of smart contract. This toolbox can reduce L2 gas cost by encoding calldata for dApps development to use as little bytes of calldata as possible.

First and Based: Be the first person to mint a unique NFT in each new block on Base

ZK-rollups use ZKPs by combining a large number of Layer 2 transactions (off-chain) into one transaction that then gets mined on the Ethereum mainnet. Instead of mining 100s of transactions individually, they can be rolled up into a single transaction.

This is a smart contract that allow a user to borrow the WatchSignals Token ($WST) by depositing a watch owned (Watch NFT) as a collateral. The watch prices are retrieved via chainlink oracle.
