Enterprise-relevant data on stablecoin settlement exposure, on-chain security risks, and why confidential payment flows are becoming a competitive necessity
Every stablecoin settlement your company executes on a public blockchain broadcasts sender identity, recipient identity, and transaction amount to anyone watching. With stablecoins settling over $52.9 trillion in transaction value over the past 12 months, this transparency creates a competitive intelligence goldmine for market observers, counterparties, and competitors. Hinkal Pay addresses this exposure by shielding all three data points while maintaining verifiable settlement—giving PSPs, OTC desks, and treasury teams the confidentiality they need without changing existing wallets or custody arrangements.
Stablecoins settled more than $52.9 trillion in transaction value over the past year, nearly doubling from $27 trillion in 2024. This staggering volume represents real enterprise payment flows—PSP merchant settlements, OTC trade completions, treasury rebalancing, and cross-border payouts. Every one of these settlements is fully visible on-chain.
Total stablecoin market capitalization reached $305 billion in early December 2025, representing a 50% increase from $204 billion at the start of the year. This capital base supports the payment infrastructure that enterprises increasingly rely on for settlement efficiency.
The total number of DeFi protocol users reached 151 million by the end of 2024, marking a 196% annual increase. This rapid expansion means more counterparties, more observers, and more sophisticated on-chain analytics monitoring your settlement patterns.
Monthly active DeFi users peaked at 22 million in September 2024, more than doubling the 2021 peak of 7.5 million. The ecosystem has matured significantly, and with maturity comes more sophisticated market observation.
Approximately 27% of global cryptocurrency users are actively engaging with DeFi platforms as of early 2025. This substantial penetration rate means your settlement counterparties—and competitors—are increasingly on-chain and equipped to analyze public transaction data.
Ethereum remains the largest DeFi hub, accounting for about 63% of total TVL, down from 71.8% at the beginning of 2024. For enterprise teams, this concentration means most settlement exposure occurs on Ethereum—making Ethereum-compatible confidentiality solutions essential. Hinkal operates across Ethereum, Solana, Tron, and Polygon, addressing exposure wherever your settlements occur.
Solana has significantly increased its DeFi market share to 10% of total ecosystem TVL. As settlement activity diversifies across chains, enterprises need multi-chain confidentiality that works with existing wallets—not solutions that require network migration.
DEX trading volumes reached an all-time high of $438 billion in December 2024. This trading activity generates substantial on-chain data that reveals market positioning, counterparty relationships, and operational patterns to anyone monitoring.
DEXs increased their share from roughly 4% to around 20% of combined CEX and DEX volume. This shift toward on-chain execution means more settlement activity is publicly visible—and more enterprise operations are exposed.
Off-chain attacks accounted for 80.5% of stolen funds in 2024, with compromised accounts making up 55.6% of all incidents. These attacks often begin with reconnaissance of on-chain transaction patterns—knowing when and how much a treasury moves makes targeting significantly easier.
Stolen funds increased by approximately 21% year-over-year to $2.2 billion in 2024. This escalating loss trend makes confidential settlement not just a competitive advantage but a security imperative.
Private key compromises accounted for 43.8% of stolen crypto in 2024. Attackers who can identify high-value wallets through on-chain analysis can focus their social engineering and technical exploitation efforts more effectively.
North Korean hackers stole $1.34 billion from crypto platforms in 2024, representing 61% of total amount stolen. State-sponsored actors actively monitor on-chain activity to identify targets—your public settlement patterns are intelligence they can use.
Total losses from top 100 DeFi hacks reached $10.77 billion from 2014-2024. The cumulative scale of these losses demonstrates that on-chain security requires more than smart contract audits—it requires operational confidentiality.
Just 19% of hacked DeFi protocols used multi-sig wallets, and only 2.4% employed cold storage. Security best practices remain inconsistent across the ecosystem, making it even more critical to limit the information attackers can gather from public settlement data.
The number of countries with dedicated regulatory frameworks for privacy assets reached 97, compared to 79 in 2023. This expansion signals that regulators are accommodating—not prohibiting—confidential financial infrastructure when proper compliance controls exist.
A total of 73 cryptocurrency exchanges worldwide have delisted at least one privacy coin by 2025, compared to 51 in 2023. This delisting trend affects solutions without compliance frameworks—not solutions like Hinkal that integrate selective disclosure via viewing keys and Know Your Transaction enforcement via Chainalysis.
Research shows only 7% of global privacy-coin transactions are suspected of illicit intent in 2025, well below public perception. The compliance narrative is shifting: confidentiality is increasingly understood as a legitimate enterprise requirement, not a red flag.
Just 20% of hacked DeFi protocols had undergone security audits. For enterprise decision-makers, this statistic emphasizes the importance of working with solutions that have comprehensive audit histories. Hinkal has completed 6 security audits.
Private transaction routing now accounts for approximately 35% to 45% of daily Ethereum transactions by year-end 2025. This adoption rate demonstrates that confidential settlement is no longer a niche requirement—it's becoming standard practice for sophisticated on-chain operators.
More than half (55.6%) of all DeFi security incidents in 2024 involved compromised accounts. Account-level attacks often leverage intelligence gathered from on-chain transaction analysis—knowing which wallets handle significant volume makes them targets.
Yield-bearing stablecoins expanded from $9.5 billion at the start of 2025 to more than $20 billion. As enterprises hold and move larger stablecoin positions for yield, the exposure from public settlement data becomes increasingly consequential.
The number of stablecoins tracked increased from 161 in early January 2025 to 214 by December, with 51 exceeding $50 million market cap. This proliferation means enterprises need confidentiality solutions that work across multiple assets and chains—not solutions locked to single tokens.
Volume of tokenized Real World Assets exceeded $16.7 billion in 2024. As traditional assets move on-chain, the same settlement exposure problems that affect stablecoin payments will affect tokenized securities, real estate, and other institutional assets.
More than half (54%) of off-chain attacks lack clear origins, highlighting how difficult attribution becomes when attackers can gather intelligence from public blockchain data before striking. Confidential settlement reduces the reconnaissance value of on-chain observation.
The data tells a clear story: on-chain financial activity is scaling rapidly, security risks are escalating, and sophisticated operators are already routing settlements through confidential pathways. For PSPs settling merchant payouts, OTC desks completing counterparty settlements, and treasury teams rebalancing liquidity, the question is no longer whether to adopt confidential settlement—but how.
Key operational implications:
The Confidential Payments SDK addresses these challenges by enabling confidential settlement and payouts without changing custody arrangements, wallets, or payment rails. Hinkal has processed over $400M in confidential on-chain volume, demonstrating production-ready scale for institutional use cases.
Hinkal integrates three compliance controls: selective disclosure via viewing keys that allow revealing full or partial transaction history to auditors or regulators on demand, KYT enforcement via Chainalysis that blocks flagged wallets at the deposit level, and custom pool deployments for heavily regulated entities with configurable compliance logic. Hinkal shields sender identity, recipient identity, and transaction amount while settlement remains publicly verifiable on the blockchain.
No. The sender routes funds through Hinkal's smart contract into a confidential balance linked to the recipient's existing wallet. The recipient connects their existing wallet and sees the confidential balance—no migration, no new wallet, no recipient-side integration required. This zero-setup flow applies across all use cases: PSP merchant settlements, OTC counterparty settlements, payroll, and vendor payouts.
Hinkal operates across Ethereum, Solana, Tron, Polygon, Base, Arbitrum, Optimism, Arc, and Tempo. Enterprises maintain existing wallets and custody arrangements while gaining settlement confidentiality. The multi-chain architecture means confidentiality travels with your operations—not locked to a single network.
PSPs settling merchant funds benefit by protecting merchant economics and counterparty relationships from observation. OTC desks benefit by shielding trade volumes and wallet patterns from market observers. Treasury teams benefit by moving capital and rebalancing liquidity without broadcasting strategy. Payroll platforms benefit by protecting headcount, pay cycles, and salary costs from competitive intelligence gathering.
Solutions that faced regulatory scrutiny lacked compliance frameworks—they offered opacity without auditability. Hinkal is compliance-ready by design: selective disclosure allows full transaction revelation to authorized parties, Chainalysis integration blocks tainted funds at the contract level, and the Integrity Check for transactions over $1,000 uses zero-knowledge proofs to verify user status without collecting personal data. This architecture positions Hinkal for institutional adoption where regulatory requirements mandate both confidentiality and auditability.
