FAQs
What is Monad?
Monad is a high-performance, EVM-compatible Layer-1 blockchain designed to bring much higher throughput and lower fees to the Ethereum ecosystem without sacrificing decentralization. It uses parallel transaction execution, an optimized consensus design, and a custom state/database architecture to achieve fast finality (around one second) and very high transaction capacity, while still allowing developers to deploy existing Ethereum smart contracts without modification.
Is Monad safe?
Monad is built with standard Layer-1 security principles, decentralized validators, audited code, and EVM compatibility, but like any new blockchain, it hasn’t been tested in the wild as long as older networks like Ethereum, so its real-world security will depend on adoption, validator diversity, and time. In other words, it’s designed to be secure, but it’s still early, so caution and good wallet practices still matter.
Does Monad provide tax documents?
Monad doesn’t provide tax documentation for users. If you need to calculate taxes on your activity, the easiest approach is to use a crypto tax calculator like Koinly. By adding your Monad wallet's public address, Koinly can import your transactions, track gains, losses, and earnings, and produce the reports you’ll need when filing.
