### [Firma.dev](https://www.g2.com/products/firma-dev/reviews)

Firma.dev is a pay-as-you-go e-signature API built for developers at startups and SaaS companies. At $0.049 per envelope with no monthly minimums, it costs a fraction of legacy platforms while delivering enterprise-grade signing capabilities. The API handles the complete e-signature workflow: document uploads, template creation, signer management, embedded signing experiences, audit trails, and webhooks. Developers can integrate Firma.dev in hours using SDKs for popular languages and comprehensive documentation. Embedded editors let you build template creation and signing flows directly into your product without redirecting users to third-party interfaces. For SaaS companies, Customer Workspaces provide private, partitioned environments for each of your customers. Templates, signers, and envelope usage stay isolated with no cross-customer data exposure. This makes Firma.dev ideal for platforms that need white-label document signing without the complexity of managing multiple accounts. Firma.dev is designed to support major e-signature legal frameworks including the U.S. ESIGN Act, UETA, and eIDAS (SES and AdES levels) in the EU. The platform helps organizations align with data protection requirements under GDPR and privacy frameworks like HIPAA. Infrastructure runs exclusively in the EU on SOC 2-certified cloud services, with security practices designed around ISO/IEC 27001 principles. Every envelope generates a tamper-evident audit trail with timestamps, IP addresses, and signer authentication records. Real-time webhooks and per-customer analytics give you visibility into signing activity across your entire platform. Getting started takes minutes. Sign up, grab your API key, and send your first envelope. Pay-as-you-go at €0.049 per envelope, no upfront cost, no monthly minimums. No sales calls, no annual contracts, no credit card required.

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
