Linea


tip

Available for Premium users only.

Linea API is available on Web3 API platform.

Linea is a network that scales the experience of Ethereum. Its out-of-the-box compatibility with the Ethereum Virtual Machine enables the deployment of already-existing applications, as well as the creation of new ones that would be too costly on Mainnet. It also enables the community to use those dapps, at a fraction of the cost, and at multiples the speed of Mainnet.

It does this by leveraging quantum-resistant lattice-based cryptography to create zero-knowledge proofs that include every transaction performed on the network, and rolling them up to Mainnet. This ensures that every transaction is recorded to the Ethereum ledger while dividing the cost of that security by magnitudes.

Monad


tip

Available for Freemium and Premium users.

Monad API is available on Web3 API platform.

Monad is an Ethereum-compatible Layer-1 blockchain with 10,000 tps of throughput, 500ms block frequency, and 1s finality.

Monad's implementation of the Ethereum Virtual Machine complies with the Cancun fork; simulation of historical Ethereum transactions with the Monad execution environment produces identical outcomes. Monad also offers full Ethereum RPC compatibility so that users can interact with Monad using familiar tools like Etherscan, Phantom, or MetaMask.

Monad accomplishes these performance improvements, while preserving backward compatibility, through the introduction of several major innovations:

Although Monad features parallel execution and pipelining, it's important to note that blocks in Monad are linear, and transactions are linearly ordered within each block.

Optimism


tip

Available for Freemium and Premium users.

Optimism API is available on Web3 API platform.

Optimism is a fast, stable, and scalable L2 blockchain built by Ethereum developers, for Ethereum developers. Built as a minimal extension to existing Ethereum software, Optimism’s EVM-equivalent architecture scales your Ethereum apps without surprises. If it works on Ethereum, it works on Optimism at a fraction of the cost.

With the OVM 2.0 upgrade, which happened on November 11th, 2021, the Optimism protocol went through its biggest upgrade to date. The primary focus of this upgrade was EVM Equivalence, a new design for Optimism that brought it close to 1:1 parity with Ethereum.
