Wakefield, Massachusetts — October 22, 2026 — The Blockchain Security Standards Council (BSSC) has released the Blockchain Transaction Lifecycle Security Standard, a specification establishing security requirements across the blockchain transaction process, from creation through signing and deployment. The framework addresses consumer-facing wallets and enterprise transaction-management systems, with the aim of ensuring that the transaction users intend to approve matches the transaction ultimately signed and executed.

What the Blockchain Transaction Lifecycle Security Standard Addresses
The Blockchain Security Standards Council announced the specification to establish security requirements for the different components involved in a blockchain transaction.
The standard focuses on a central security requirement: the intent captured when a transaction is created should match the transaction ultimately signed and deployed. Maintaining this consistency is intended to help users understand and verify what they are approving.
The specification addresses transaction security across:
- Consumer-facing wallets: Applications through which users prepare and approve blockchain transactions.
- Enterprise transaction workflows: Specialized tools organizations use to manage blockchain transactions.
- Transaction lifecycle components: The systems and components involved in preparing, signing, and deploying transactions.
- Security verification and transparency: Requirements intended to help ensure transaction data is verified, validated, and protected.
A Lifecycle-Based Approach to Blockchain Security
The BSSC standard addresses a longstanding challenge in blockchain security: protecting the integrity of a transaction as it moves through different stages and systems.
The announcement identifies the 2025 Bybit hack, valued at approximately $1.5 billion, alongside smaller but more frequent incidents that contribute to recurring losses, as examples of the broader security challenges facing the industry.
Rather than focusing only on the security ranking of individual wallets, the new specification establishes requirements for implementations across the transaction ecosystem.
Its approach covers both:
- All-in-one wallet applications, which bring transaction-related functionality together in a single application.
- Component-based transaction systems, which organizations may use to meet more sophisticated operational requirements.
The standard is designed to accommodate different use cases and system architectures while maintaining expectations for security and transparency.
What the Standard Means for Developers and Organizations
The specification is intended for stakeholders responsible for building, operating, deploying, or evaluating blockchain transaction infrastructure.
Its intended audiences include:
- Wallet and transaction-tool developers building applications and systems that process blockchain transactions.
- Organizations managing blockchain transactions that need to assess and strengthen the security of their workflows.
- Smart contract teams deploying contracts to blockchain networks.
- Technology procurement leaders evaluating transaction infrastructure and associated security requirements.
- Security leaders responsible for assessing the protections implemented across transaction systems.
By defining requirements across the transaction lifecycle, the standard provides a framework these stakeholders can use to evaluate their systems and implement recommended protections.
Max Courchesne-Mackie on Transaction Security Standards
Max Courchesne-Mackie, Director of Security Engineering at Figment and co-editor of the specification, described the standard as a framework for addressing security requirements across transaction systems.
“The Blockchain Transaction Lifecycle (BTL) Standard is a first-of-its-kind framework designed to establish security best practices for transaction systems that have historically received limited scrutiny,”
He added:
“By defining the transaction lifecycle broadly, the standard accommodates a wide range of use cases and system architectures while maintaining rigorous expectations for security and transparency.”
The comments emphasize the specification’s broad lifecycle coverage and its intention to support varied system architectures without lowering security and transparency expectations.
Strengthening Trust Across the Blockchain Ecosystem
The BSSC stated that wider adoption of the standard could improve security beyond individual organizations by encouraging more consistent protections across blockchain transaction tools.
The council identifies several intended benefits:
- Improved transaction-data protection: Consistent requirements for verifying, validating, and protecting transaction data.
- Stronger implementation practices: Security requirements that apply across transaction tools and their components.
- Reduced systemic risk: Broader adoption of consistent safeguards across the ecosystem.
- Fewer recurring losses: Better implementation of transaction security protections intended to reduce exposure to recurring transaction-related losses.
- Greater ecosystem trust: More consistent security and transparency across the systems used to prepare and execute transactions.
These are the objectives associated with adoption of the standard; the announcement does not claim that publication alone eliminates transaction risk or guarantees that losses will be prevented.
Review the Specification and Participate in Standards Development
BSSC encourages organizations that develop or use blockchain transaction tools to review the specification, evaluate their systems against its requirements, and implement the recommended protections.
Recommended next steps:
- Review the Blockchain Transaction Lifecycle Security Standard.
- Assess how existing transaction systems align with the specification’s requirements.
- Implement the recommended protections relevant to the systems being used or developed.
- Provide feedback to help refine and strengthen future versions of the standard.
- Visit blockchainssc.org for further information and opportunities to participate in BSSC standards development efforts.
The council is inviting industry participants to contribute feedback as the standard evolves.
