Data-driven analysis revealing why confidential stablecoin settlements are becoming essential for enterprise settlement for PSPs, OTC desks, and enterprise treasury teams
Stablecoins processed $46 trillion in transaction volume over the past year — yet every single settlement remains permanently visible on public blockchains. For payment companies settling merchant funds, OTC desks executing bilateral trades, and treasury teams moving capital between entities, this transparency creates a competitive intelligence liability that traditional payment rails never imposed. Hinkal Pay addresses this gap by shielding sender identity, recipient identity, and transaction amount while maintaining verifiable settlement across Ethereum, Solana, Tron, and major EVM chains.the Hinkal SDK provides a drop-in solution that adds confidentiality without changing custody arrangements, wallets, or payment rails.
The scale of stablecoin settlement has reached a level that demands institutional-grade confidentiality controls. According to a16z crypto's State of Crypto Report, stablecoins processed $46 trillion in total transaction volume — a 106% increase from the prior year. For PSPs and payment companies, this volume represents billions in merchant settlements that remain permanently visible to competitors, counterparties, and market observers.
When removing bot activity and wash trading, genuine stablecoin transaction volume still reached $9 trillion in the past 12 months. This adjusted figure represents actual business settlements — payroll disbursements, vendor payments, OTC settlements, and treasury transfers — all of which broadcast commercial relationships on public ledgers.
Enterprise stablecoin adoption is accelerating rapidly. 54% of enterprises expect to adopt stablecoins within 6-12 months, according to EY-Parthenon research. This incoming wave of enterprise settlement activity will land on public chains without confidentiality controls — exposing payment volumes, counterparty relationships, and treasury positions to competitors from day one unless confidential settlement is implemented at adoption.
Cross-border supplier payments dominate enterprise stablecoin demand, with 77% of corporates identifying it as their primary use case. These settlement flows — vendor payments, partner payouts, and inter-entity transfers — expose commercial relationships and payment terms on public chains where competitors can analyze every transaction.
Privacy coins are used in 11.4% of all cryptocurrency transactions globally as of Q1 2025, up from 9.7% in 2024. But enterprise confidentiality demand extends far beyond privacy coins — PSPs, OTC desks, and treasury teams need confidential settlement for standard stablecoins like USDT and USDC on existing chains, a market that privacy coins don't serve.
Hinkal's Private Send addresses this gap by transforming any stablecoin transfer into a confidential transaction — without requiring recipients to change wallets, integrate new systems, or adopt new custody arrangements.
The blockchain technology market was valued at $31.18 billion in 2025, with projections reaching $577.36 billion by 2034. This 36.5% CAGR reflects enterprises moving critical financial infrastructure on-chain — including settlement flows that require confidentiality controls unavailable in most current implementations.
Cross-border payments represent a primary blockchain use case, with 60% of users deploying the technology for international money transfers. For payment companies and PSPs operating globally, this creates exposure across multiple jurisdictions where settlement patterns can be analyzed by competitors and regulators alike.
B2B stablecoin payment volumes have exploded, growing from under $100 million monthly in 2023 to over $3 Billion monthly by 2025. This 30x increase represents real enterprise settlement activity — vendor payments, partner settlements, and cross-border payouts — all broadcasting commercial relationships on public ledgers. As these volumes continue growing, the competitive intelligence exposure compounds with every transaction.
Speed is the primary driver for enterprise stablecoin adoption. 48% of stablecoin users report real-time settlement as the top advantage over traditional payment rails, ahead of cost savings. But this speed comes with a trade-off traditional rails never imposed — every settlement is permanently and publicly recorded, giving competitors, counterparties, and market observers real-time visibility into your payment operations.
The counterparty base for enterprise stablecoin settlement is expanding rapidly. Active stablecoin wallets increased from 19.6 million in February 2024 to over 30 Million in February 2025 — a 53% year-over-year increase. Every new wallet represents a potential settlement counterparty whose payment relationship with your business becomes publicly visible on-chain without confidential settlement controls.
Financial institutions implementing blockchain technology can achieve annual savings of $8-12 billion through improved transaction security and operational efficiency. However, these savings come with new exposure risks: settlement patterns that were previously invisible now become permanently visible competitive intelligence.
Security remains a persistent concern for financial enterprises. Nearly 45% of financial institutions experience fraud and cybercrime every year. Transparent on-chain settlements create additional attack vectors — bad actors can identify high-value targets, map payment relationships, and time attacks based on settlement patterns.
Hinkal's protocol shields three critical data points — sender identity, recipient identity, and transaction amount — eliminating the reconnaissance opportunities that transparent settlements provide to malicious actors.
The scale of security incidents continues to grow, with crypto users losing $17 billion to hacks and scams in 2025. While not all losses stem from transparent settlements, visible wallet balances and transaction patterns contribute to targeting decisions by sophisticated attackers.
The technology enabling compliant confidentiality is scaling rapidly. The global zero-knowledge proof market was valued at $1,277.7 million in 2024, with projections reaching $7,585.6 million by 2033. This growth reflects enterprise demand for cryptographic solutions that provide confidentiality without sacrificing auditability.
Hinkal's compliance framework leverages zero-knowledge proofs through the Reclaim Protocol, enabling enterprises to prove verification status without revealing identity data — Hinkal receives only a cryptographic proof confirming verification, never names, IDs, or personal documents.
Enterprise investment in zero-knowledge technology shows no signs of slowing. The ZKP market is exhibiting a 22.1% CAGR from 2025 to 2033, driven primarily by financial services demand for compliant confidentiality solutions.
Regulatory clarity is improving globally. 97 countries now have dedicated regulatory frameworks addressing digital asset privacy, up from 79 in 2023. This expansion signals growing regulatory acceptance of confidential transaction technology when paired with appropriate compliance controls.
Financial services is driving ZKP adoption. The BFSI sector accounted for the largest share of zero-knowledge proof market adoption in 2024, reflecting banks, payment processors, and financial institutions prioritizing compliant confidentiality for settlement operations.
Enterprise demand for zero-knowledge technology is concentrated in major financial centers. North America captured 27.8% of global ZKP market revenue in 2024, reflecting US-based payment companies and financial institutions investing in compliant confidentiality solution.
The same financial centers driving ZKP adoption are also leading blockchain deployment. North America contributed over 40% of global blockchain market revenue in 2024, creating a concentrated market where confidential settlement capabilities provide immediate competitive advantage.
Hinkal operates as a confidentiality solution across Ethereum, Solana, Tron, Polygon, Base, Arbitrum, Optimism, Arc, and Tempo — the chains where enterprise settlement volumes are concentrated.
Enterprise ZKP adoption is primarily software-driven. The software segment captured 52.7% of global ZKP market revenue in 2024, indicating that enterprises prefer integrating confidentiality capabilities into existing systems rather than migrating to new infrastructure.
This aligns with Hinkal's approach: enterprises maintain existing wallets, custody arrangements, and payment rails while gaining confidential settlement capabilities through SDK integration.
Banking and financial services represent the largest blockchain vertical by market value. The banking sector holds 29.7% of blockchain market value distribution in 2026. For payment processors and settlement providers serving this vertical, confidential settlement capabilities become a competitive differentiator rather than a nice-to-have feature.
PSPs settling merchant funds on public chains expose merchant economics, counterparty relationships, and operational patterns. With Hinkal's SDK integration, PSPs can settle funds to a merchant's confidential balance inside the Hinkal smart contract — merchants connect their existing wallet to see the private balance and execute payouts, with no merchant-side integration required.
Regional growth patterns highlight where confidential settlement demand is accelerating. APAC emerged as the fastest-growing region for on-chain crypto activity, with a 69% year-over-year increase. For payment companies and OTC desks operating across APAC markets, this growth creates proportional exposure as settlement volumes become visible to regional competitors.
Major stablecoin issuers are recognizing the enterprise demand for confidential settlements. Paxos partnered with Aleo to develop USAD, a private yet compliant stablecoin, in 2025. This institutional validation signals that confidential stablecoin settlement is moving from experimental to production-ready.
The statistics above reveal a clear pattern: enterprises are adopting blockchain for settlement at scale, but confidential transaction adoption remains below 12%. This gap creates opportunity for wallet providers who integrate confidential settlement capabilities.
Key market dynamics for wallet providers:
Hinkal is the only multi-chain solution that gives wallets confidential send where the recipient also receives confidentially. Once one wallet integrates Hinkal, users can send confidentially to recipients on any other wallet. recipient connects their existing wallet to access confidential balance via Hinkal Pay - no shared infrastructure required between wallets. This creates competitive advantage without fragmenting the ecosystem.
The data points toward accelerating demand for confidential enterprise settlement:
Based on the statistical evidence, payment companies and treasury teams should prioritize:
Hinkal's Viewing Keys enable enterprises to reveal full or partial transaction history to auditors, regulators, exchanges, or internal compliance teams on demand — maintaining confidentiality for commercial purposes while satisfying regulatory requirements.
Stablecoins processed $46 trillion in transaction volume over the past year — all permanently visible on public blockchains. For PSPs, OTC desks, and treasury teams, this transparency exposes merchant economics, counterparty relationships, settlement volumes, and operational patterns to competitors and market observers. With 54% of enterprises planning to adopt stablecoins within 6-12 months, the volume of exposed settlement activity will only grow — making confidential settlement a competitive necessity rather than an optional feature.
Institutional-grade confidentiality provides selective disclosure capabilities alongside transaction shielding. Hinkal shields sender identity, recipient identity, and transaction amount while maintaining verifiable settlement on the blockchain. Viewing Keys allow enterprises to reveal full or partial transaction history to auditors, regulators, or compliance teams on demand. This approach satisfies the requirements of the 97 countries with dedicated regulatory frameworks while protecting commercial confidentiality.
Yes. With Hinkal, the recipient requires zero setup — no new wallet, no integration, no migration. The sender routes funds through Hinkal's smart contract into a confidential balance linked to the recipient's existing wallet. The recipient connects their current wallet and sees the confidential balance. This frictionless approach is critical for PSPs settling with merchants, OTC desks settling with counterparties, and enterprises paying vendors at scale.
Zero-knowledge proofs enable enterprises to verify credentials and compliance status without revealing underlying identity data. The ZKP market, valued at $1.28 billion in 2024 and growing at 22.1% CAGR, reflects enterprise investment in this capability. Hinkal's Integrity Check uses ZK proofs via Reclaim Protocol — users prove verification status without revealing names, IDs, or personal documents. This satisfies AML/CFT requirements while preserving the confidentiality that enterprises require.
Most alternatives shield only one dimension — concealing the sender but not the amount still exposes enough data for competitors to map volumes. Hinkal shields all three critical data points: sender identity, recipient identity, and transaction amount. Settlement remains publicly verifiable on the blockchain, but the commercial relationships and financial details remain confidential. The Confidential Payments SDK enables enterprises to integrate this capability into existing products without changing custody arrangements, wallets, or payment rails.
