What is Monad?

The short version

Monad is fully compatible with the Ethereum Virtual Machine (EVM). Solidity contracts, wallets like MetaMask and tools like Foundry or Hardhat work without changes. What's different is underneath: Monad redesigns how transactions are ordered, executed and stored so the chain can target around 10,000 transactions per second with blocks around every 300 milliseconds and finality in about 600 milliseconds.

Why speed matters for money

Payments, trading and automated agents all need fast confirmation and predictable fees. On slower chains, a simple transfer can wait in a queue and cost more when the network is busy. Monad's goal is to make on-chain money feel as quick as tapping a card, while keeping it open and self-custodied.

The four big ideas

1. Parallel execution

Most EVM chains run transactions one after another. Monad runs many at once optimistically, then checks for conflicts and re-runs only the ones that touched the same data. The final result is identical to running them in order, so apps behave exactly as expected.

2. MonadBFT consensus

MonadBFT is a pipelined Byzantine fault tolerant protocol derived from the HotStuff family. Validators agree on block order in a small number of message rounds, which helps the network reach finality quickly even with many validators.

3. Asynchronous execution

Monad separates agreeing on transaction order from executing them. Consensus can move on to the next block while execution catches up, so neither step blocks the other and the whole time budget per block is used efficiently.

4. MonadDb

MonadDb is a custom database built to store Ethereum-style state on SSDs with asynchronous reads. Storage access is often the real bottleneck of a blockchain, and a purpose-built database removes much of that cost, which also keeps hardware requirements for node operators reasonable.

Monad vs Ethereum vs other L1s

• Ethereum: the most decentralized and battle-tested EVM chain, but lower throughput on Layer 1; scaling largely happens through rollups.
• Rollups (L2s): inherit Ethereum security but add bridging steps and fragment liquidity across many networks.
• Monad: a single high-throughput EVM Layer 1, so users get one shared state with Ethereum tooling and fast blocks.
• Non-EVM high-speed chains: often fast, but require new languages, wallets and tooling.

What people use Monad for

• Low-cost payments and transfers in MON and stablecoins
• Decentralized exchanges and order books that need fast blocks
• Liquid staking, lending and yield vaults
• On-chain AI agents that make many small transactions
• Games and consumer apps where waiting is not an option

Key terms

• MON: the native token used to pay gas and to stake.
• Validator: a node that proposes and votes on blocks.
• Finality: the point after which a transaction can't be reversed.
• Gas: the fee you pay for computation on the network.

Figures like throughput and block time are design targets published by the Monad team; real performance varies with network load.
