Top Flutter Web3, Crypto and Blockchain packages
Last updated: August 11, 2025
Blockchain is a distributed database that maintains a growing list of records, called blocks, which are secured using cryptography. Blockchain is used to store data such as transactions made on the Bitcoin network. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.
Web3 has become a catch-all term for the vision of a new, better internet. At its core, Web3 uses blockchains, cryptocurrencies, and NFTs to give power back to the users in the form of ownership. It is a decentralized application platform that runs on the blockchain and allows developers to create decentralized applications (dApps) that can be executed on the blockchain network.
Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control.
The complete list of Dart and Flutter packages that provide Web3, Cryptocurrency, DApps and Blockchain APIs is given below.
