SignChain pricing is not publicly listed. No published plan prices were found on SignChain’s public pricing-related pages. Public information is ambiguous: Amygdalab Ltd maintains a SignChain blockchain platform page, while signchain.ai describes SignChain as a blockchain-powered product of Advantev. Buyers should confirm the vendor entity during evaluation. Contract length is not publicly documented; ask whether monthly, annual, pilot, or enterprise terms are available.
SignChain is a blockchain-based eSignature platform that records signed documents on a distributed ledger, providing cryptographically verified, immutable audit trails. The platform targets organizations that require high-assurance document integrity: legal practices managing sensitive contracts, financial services firms with regulatory audit requirements, and businesses operating in jurisdictions where blockchain-backed records carry legal weight. Likely pricing questions to ask include document volume, blockchain fees, API usage, identity verification requirements, and support and SLA terms.
The pricing structure raises practical questions for buyers. What drives the cost in a contact-based model? How should teams evaluate SignChain against alternatives with transparent pricing? When does blockchain-anchored signing provide genuine compliance value over PKI-based alternatives? This guide covers SignChain’s pricing model, the questions to ask during a sales conversation, and how SignChain compares to DocuSign, Adobe Sign, Dropbox Sign, and developer-first alternatives with published pricing.
Key Takeaways
- No published plan prices were found on SignChain’s public pricing-related pages. All pricing is negotiated through direct sales contact.
- SignChain does not publicly document a free tier or developer sandbox in the official sources reviewed; confirm free-tier and sandbox availability directly with the vendor.
- Public information is ambiguous on the vendor: Amygdalab Ltd maintains a SignChain blockchain platform page, while signchain.ai describes SignChain as a product of Advantev. Confirm the vendor entity before entering procurement.
- Contract length is not publicly documented; ask whether monthly, annual, pilot, or enterprise subscription terms are available.
- Likely pricing questions to ask include: document volume, blockchain transaction fees, API usage scope, identity verification requirements, and support and SLA tier.
- Alternatives with transparent published pricing include: Verdocs (free tier, 25 envelopes/month, no credit card required), DocuSign (Personal $10/month; Standard $25/user/month; Business Pro $40/user/month, billed annually), and Dropbox Sign (Essentials $15/month; Standard $25/user/month).
- For development teams building embedded signing into their own applications, Verdocs provides a self-serve free tier with full API access, 25 envelopes per month, 60+ native web components, and no credit card required.
Why Teams Research SignChain Pricing
Three buyer scenarios account for most SignChain pricing searches.
- No self-serve pricing to evaluate. Unlike most eSignature platforms, SignChain requires direct sales contact before any cost estimate is available. For teams that need a budget number before committing to a sales process, this creates friction that shifts evaluation priority toward alternatives with publicly listed pricing first.
- Blockchain infrastructure complexity before commitment. Blockchain infrastructure integrations carry meaningful technical complexity. Most technical buyers need to validate the API and integration before signing a contract. Whether SignChain offers a sandbox or pilot environment before a commitment is a material evaluation question that should be raised early.
- Comparing against transparent-pricing alternatives. Teams evaluating SignChain are almost always comparing it against platforms with published tiers. Understanding where blockchain-anchored signing provides genuine compliance value over PKI-based alternatives (and where it does not) shapes whether the contact-based evaluation process is worth the time investment.
This guide answers all three before you need to contact sales.
SignChain Pricing Model in 2026
SignChain does not publish plan tiers, prices, or pricing structure on its publicly available pages. All cost information requires direct sales contact.

What Is SignChain?
SignChain is a blockchain-based eSignature platform that anchors signed documents to a distributed ledger, creating cryptographically verified, immutable audit trails.
Plan Summary:
- Pricing: Custom, contact sales directly
- Deployment: Blockchain-anchored (distributed ledger)
- API Access: Not publicly documented
- Free Tier: Not publicly documented
- Best For: Organizations requiring blockchain-anchored document integrity for high-assurance compliance workflows
What SignChain publicly supports:
- On-chain signing: each signed document is anchored to a blockchain, creating a tamper-evident record
- Identity verification: identity pillar supporting signer authentication alongside signature and notarization workflows
- Notarization: notarization pillar for documents requiring a higher level of record integrity
- Immutable audit trail: distributed ledger record that exists outside any single organization’s control
Blockchain vs PKI Signing in Practice
Where most eSignature platforms use PKI (Public Key Infrastructure) certificates to verify signature authenticity, SignChain takes a decentralized approach. Each signed document is anchored to a blockchain, creating a tamper-evident record. Altering the document after signing becomes mathematically detectable even if the platform itself were compromised. This infrastructure overhead is what drives the custom pricing model and distinguishes SignChain’s cost structure from per-user or per-envelope alternatives.
Best For
Organizations where regulatory requirements specifically mandate blockchain-anchored records: certain government contracts, cross-border agreements where blockchain signatures carry distinct legal status, or blockchain-native platforms with on-chain audit trail requirements. Legal practices, financial services firms, and insurance organizations with high-assurance compliance requirements and enterprise procurement budgets.
Questions to Ask in a SignChain Sales Conversation
Because SignChain pricing is fully contact-based, the quality of your evaluation depends on the questions you bring to the sales process.
Pricing and Cost Structure
- What is the unit of pricing: per document, per envelope, per signing event, per API call, or per user?
- Are blockchain transaction fees included in the price or billed separately? If separate, how are they calculated and capped?
- Is there a minimum annual contract value?
- What happens when volume limits are exceeded? What are the overage rates?
- What is included in the base implementation vs. billed as professional services?
Contract and Evaluation Terms
- What contract lengths are available: monthly, annual, pilot, or multi-year?
- Is a sandbox or trial environment available before signing a contract?
- What are the renewal terms? Are price increases automatic at renewal?
- What compliance reports are included in the base contract vs. add-ons?
Technical and Integration Questions
- Which blockchain network does SignChain use? Are transaction fees fixed or variable?
- What does API access include? Are there rate limits or per-call fees?
- What is the audit trail format, and is it acceptable in your jurisdiction for regulatory proceedings?
- What frameworks and SDKs are available for integration?
SignChain Free Tier and Evaluation Access
SignChain does not publicly document a free tier or developer sandbox in the official sources reviewed. The existence of app.signchain.ai suggests a live application environment, but no published free-tier statement was found.
What is known:
- No publicly documented free plan
- No confirmed self-serve sandbox
- Evaluation typically proceeds through a sales-led process
Teams that require sandbox access or a pilot environment before committing to a contract should raise this requirement at the first sales conversation. For teams that need to validate API behavior and integration architecture before entering procurement, platforms with self-serve developer tiers provide an alternative evaluation path before a SignChain sales engagement.
SignChain’s Enterprise Pricing Model
SignChain uses a contact-based enterprise pricing model. This is common among blockchain infrastructure providers and enterprise-focused compliance software platforms, and reflects several structural factors in blockchain-based signing.
Why Blockchain Signing Uses Custom Pricing
Blockchain transactions carry computational overhead that traditional PKI-based signing does not. Gas fees on public chains fluctuate with network activity; permissioned or private blockchain networks require maintained infrastructure. Customer use cases also differ significantly: a legal firm anchoring 50,000 contracts per month to a blockchain has a fundamentally different cost profile than a fintech startup running 200 signatures per week. Contact-based pricing allows the platform to tailor the package to each deployment.
Likely Pricing Variables
While SignChain does not publish its pricing drivers, likely questions to raise during evaluation include:
- Document or signing event volume per month
- Blockchain network type and associated transaction fee structure
- API usage scope, including call volume and webhook requirements
- Identity verification and notarization requirements
- Support tier and SLA requirements
- User count or seat licensing model
What to Expect in the Sales Process
Entering a SignChain evaluation means committing time to a sales-led process before any cost estimate is available. Teams should prepare monthly document volume data, integration requirements, compliance deliverables, and support expectations before the first conversation to receive an accurate proposal. Ask for a sandbox or pilot environment as a condition of evaluation before signing any contract.
SignChain Pricing vs Competitors
SignChain vs DocuSign
DocuSign is a widely deployed eSignature platform with published per-user pricing. DocuSign Personal is $10/month; Standard is $25/user/month; and Business Pro is $40/user/month, all billed annually. Standard and Business Pro annual plans include up to 100 envelopes per user per year; monthly plans include up to 10 envelopes per user per month; usage above the annual allowance may be billed pay-as-you-go. DocuSign provides 1,000+ cloud-based integrations. A direct cost comparison with SignChain is not possible without a SignChain quote. The meaningful comparison is functional: DocuSign is a portal-first platform with a separate API layer; SignChain is a blockchain-first platform targeting audit trail integrity via distributed ledger. The right comparison depends on whether blockchain-anchored records are a genuine compliance requirement.
SignChain vs Adobe Sign
Adobe publishes Acrobat business plan pricing with e-signature features included: Acrobat Standard for teams is $16.99/license/month and Acrobat Pro for teams is $23.99/license/month, annual billed monthly. Enterprise Acrobat Sign Solutions are sales-led and custom-priced. Adobe offers a free trial for Acrobat Sign Solutions; no always-free tier was found in official Adobe sources reviewed. Adobe Sign integrates with Acrobat, Creative Cloud, and Microsoft 365 for document-centric workflows. Teams evaluating Adobe Sign alongside SignChain are typically choosing between a document-ecosystem platform and a blockchain compliance platform.
SignChain vs Dropbox Sign
Dropbox Sign publishes tiered pricing: a free package with up to three signature requests per month, a 30-day trial, Essentials at $15/month for individual use, and Standard at $25/user/month, with annual discounts shown on the pricing page. Dropbox Sign offers separate API plans with embedded signing, embedded requesting, templates, OAuth, SDKs in six languages, audit trails, and technical support. For teams with standard signing workflows and a preference for transparent self-serve pricing, Dropbox Sign provides a lower-friction evaluation path than SignChain’s contact-based process.
SignChain vs Verdocs
Verdocs is the most developer-focused embeddable eSignature platform for teams building signing directly into their own applications. Verdocs is built on an API-first design with 60+ native web components (React, Angular, Vue, vanilla JS, Node.js, TypeScript) and full CSS control for white-label in-app signing. Verdocs supports both native web components and iframe options, with web components recommended for deeper styling and framework-native integration. Open-source SDKs (MIT license), SOC 2 Type I certification, 2048-bit RSA encryption, HSM key storage, and PKI digital certificates address the security and compliance requirements development teams verify before integration. The free tier includes API access and 25 envelopes per month with no credit card required; KBA and SMS are available as add-ons.
API and Developer Pricing on SignChain
SignChain’s public API availability and pricing are not documented on its official sources reviewed. Teams evaluating SignChain for programmatic or embedded signing workflows should raise API access requirements during the sales process.
What to Ask About SignChain’s API
- Is API access included in the base contract or priced separately?
- What endpoints are available: document creation, signer routing, status webhooks, and completed document retrieval?
- Are there rate limits or per-call fees?
- What SDK or client library support is available?
- What embedded signing model does the API support?
Embedded Signing Considerations
For development teams building applications where end users sign documents natively inside their own product UI, understanding SignChain’s embedded signing architecture before entering procurement is essential. Platforms offering self-serve developer tiers with native web components allow teams to prototype and validate embedded workflows before committing to a contact-based enterprise evaluation process.
SignChain Blockchain Compliance and Use Cases
SignChain’s strongest differentiation is its blockchain-anchored audit trail architecture, in a compliance category where standard PKI-based signing may not satisfy specific regulatory requirements.
When Blockchain Signing Provides Genuine Value
- Regulatory mandates for blockchain records: certain government contracts, cross-border agreements, or jurisdictions where blockchain-backed records carry a distinct legal status
- Tamper-evident infrastructure requirements: organizations where the integrity of the audit trail must be provable, independent of any single platform or vendor
- On-chain audit trail requirements: blockchain-native platforms that require signed agreements to be anchored to the same distributed ledger as other platform records
When PKI-Based Alternatives Are Sufficient
For most commercial signing workflows, PKI-based signing with HSM key storage, 2048-bit RSA encryption, and PKI digital certificates satisfies ESIGN Act and UETA requirements and produces legally binding, tamper-evident signed documents without blockchain infrastructure overhead. Organizations should confirm whether their compliance requirements specifically mandate blockchain-anchored records or whether PKI-based alternatives meet the same standard before committing to a blockchain-first evaluation process.
Confirming Compliance Requirements
Before entering a SignChain sales evaluation, confirm with your legal and compliance teams: does your regulatory environment require blockchain-anchored records, or is a PKI-based audit trail with cryptographic non-repudiation sufficient? The answer determines whether SignChain’s infrastructure overhead is justified or whether a wider set of alternatives applies.
Final Verdict
SignChain’s pricing model is well-matched for a specific buyer. Here is how to decide without committing to a full sales process first.
For teams choosing SignChain:
- For organizations with genuine blockchain compliance requirements: If your regulatory environment specifically mandates blockchain-anchored records for document signing, SignChain is worth a direct sales conversation. Confirm the vendor entity (Amygdalab Ltd or Advantev), prepare document volume and API usage data before the first meeting, and ask for sandbox access as a condition of evaluation.
- For high-assurance industries with enterprise procurement budgets: Legal practices, financial services firms, and insurance organizations running large contract volumes in regulated environments where blockchain audit trails provide distinct compliance value. The contact-based model is standard for this category of enterprise software.
- For organizations without API embedding requirements: Teams using a standalone signing portal for internal compliance workflows, rather than building signing into a customer-facing product, can evaluate SignChain without requiring native web component embedding.
For teams where an alternative is the better fit:
- For developers embedding signing into their own application: Verdocs is purpose-built for this use case, with 60+ native web components, full CSS control over every signing UI element, a permanent free tier with API access and 25 envelopes per month, and open-source SDKs (MIT license). Verdocs includes a self-serve evaluation path before any commercial conversation; SignChain requires a sales process first.
- For legal, insurance, real estate, and accounting teams building regulated document workflows: Verdocs provides industry-specific embedded eSignature with full document lifecycle management, purpose-built for regulated signing workflows inside practice management or client portal software, with PKI-based compliance that satisfies ESIGN Act and UETA requirements.
SignChain’s blockchain infrastructure is genuinely differentiated for compliance environments where distributed ledger records are a specific requirement. When self-serve API evaluation, transparent pricing, and native web component embedding matter before any contract conversation, evaluate developer-first alternatives before committing to a contract-based enterprise process.
