Get Ready to Participate in Carbonable’s Premium Carbon Removal Projects

Announcement

We are excited to announce the imminent opening of the first Carbon Removal Project’s financing on the Carbonable platform on Starknet.

Please make sure you read the following prerequistes in order to participate in Carbonable’s funding opportunities.

1. Get a Starknet Wallet

What is Starknet?

Starknet is a permissionless L2 decentralized validity Rollup over Ethereum.
-Starknet allows any dApp to achieve unlimited scale for its computation, without compromising Ethereum’s composability and security, by using scalable cryptographic validity proofs — STARKs.
Starknet is developed in-house by StarkWare and powers all our production-grade applications.

Why the need for a Starknet Wallet when I have Metamask?

Metamask and Starknet wallets are both software wallets that allow users to store, send and receive cryptocurrency. However, they don’t operate with the same networks.

Metamask is a browser extension that can be used on any browser and interacts with the Ethereum EVM-compatible networks network. It has an interface that is designed for easy navigation. Metamask has a variety of features such as built-in token swap, ERC-20 token support, and the ability to connect to decentralized applications (dApps) on the Ethereum network. It also provides security for your tokens and private keys by using seed phrases and password protection, and has an additional feature that allows you to set a security pin.

Starknet wallets are browser extensions too, but interact with the the Starknet network which is not EVM-compatible. They provide a more advanced interface that is geared towards developers and experienced users. Thus some features are similar to the one of Metamask but can only operate on Starknet. StarkNet wallets also provide security for your tokens and private keys by using seed phrases and password protection.

In summary, both Metamask and Starknet wallets are software wallets that provide security for your tokens and private keys, but they are designed for different ecosystems yet share similar features through different user interfaces.
