# Best Smart Contracts Software - Page 2 *By [Brandon Summers-Miller](https://research.g2.com/insights/author/brandon-summers-miller)* Smart contracts are protocols used to facilitate, verify, and enforce contracts on a digital medium. These self-executing contracts can be safely executed and authenticated without third parties and cannot be reversed. Each transaction is documented on a blockchain or distributed ledger system, increasing traceability and transparency. Companies use smart contracts to improve the security of transactions. Smart contracts are heavily encrypted and provide superior protection over standard encryption technology. Their self-executing nature can speed up transactions and increase accuracy as well. Smart contracts also improve transparency since requirements are well-defined and transactions are documented and irreversible. Some [blockchain platforms](https://www.g2.com/categories/blockchain-platforms) and [blockchain payment](https://www.g2.com/categories/blockchain-payments) solutions offer smart contracts or allow users to create, manage, and execute transactions digitally. Additionally, [smart contract audit service providers](https://www.g2.com/categories/smart-contract-audit-services) help businesses assess the security and reliability of smart contracts. To qualify for inclusion in the Smart Contracts category, a product must: - Be built upon a blockchain-based platform or distributed ledger technology (DLT) system - Allow users to predefine contract terms and events - Create digital, self-executing contracts - Settle transactions without third parties ## How Many Smart Contracts Software Products Does G2 Track? **Total Products under this Category:** 41 ### Category Stats (May 2026) - **Average Rating**: 4.28/5 - **Buyer Segments**: Small-Business 100% - **Top Trending Product**: Venly (+0.002) *Last updated: May 20, 2026* ## How Does G2 Rank Smart Contracts Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 100+ Authentic Reviews - 41+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts.
