Enterprises operating on public blockchains face a fundamental tension: blockchain transparency exposes every settlement, payout, and treasury movement to competitors, counterparties, and market observers. Three distinct approaches to confidential computing (Hinkal, Aztec Network, and Inco Network) offer different solutions to this challenge. While Aztec builds programmable privacy through an Ethereum-specific rollup and Inco pioneers fully homomorphic encryption for encrypted computation, Hinkal delivers institutional-grade confidential settlement across multiple chains without requiring migration, new wallets, or smart contract modifications. Understanding these fundamental differences helps enterprise decision-makers select the approach that matches their operational requirements, compliance obligations, and time-to-value expectations.

Understanding Each Company's Core Positioning

Hinkal: Multi-Chain Confidential Settlement for Enterprise Workflows

Hinkal operates as an institutional-grade solution enabling confidential transactions on public blockchains while maintaining verifiable settlement. The company serves Payment Service Providers, OTC desks, payroll platforms, and treasury teams who need to shield settlement volumes, counterparty relationships, and operational patterns from on-chain observers.

Hinkal's core differentiator is bridging institutional privacy requirements with public blockchain transparency through privacy-by-default architecture with built-in compliance controls. The technology shields sender identity, recipient identity, and transaction amount, ensuring that counterparties, competitors, and market watchers cannot map commercial relationships or financial details from on-chain data. Settlement remains publicly verifiable on the blockchain, but the confidential solution obscures the sensitive business information.

Aztec Network

Aztec positions itself as a privacy-first zkRollup on Ethereum with programmable private smart contracts. Founded by investors including Consensys, Aztec focuses on enabling developers to build entirely new private decentralized applications using its Noir programming language. The Alpha Network launched in 2025, representing the first privacy-focused execution environment with day-one decentralization.

Aztec's approach requires migration to its Ethereum-specific rollup environment. Developers must learn Noir, and existing protocols cannot integrate without significant architectural changes. This makes Aztec well-suited for greenfield projects requiring custom privacy logic.

Inco Network

Inco Network takes a different technical approach, using fully homomorphic encryption combined with trusted execution environments (TEEs) to enable computation on encrypted data without decryption. This novel cryptographic approach provides unique capabilities for encrypted state storage and programmable view access.

Currently operating on Base Sepolia testnet and Solana devnet, Inco remains in early-stage development. The technology offers NIST-approved post-quantum security and familiar developer tooling through Solidity and Rust support.

Comparing Privacy Mechanisms and Zero-Knowledge Approaches

The three solutions employ fundamentally different cryptographic approaches to achieve data protection.

Hinkal's privacy architecture:

• zkSNARKs combined with shielded pools and stealth addresses
• Transaction-level confidentiality covering amounts, senders, and recipients
• ZK-TLS method via Reclaim Protocol for privacy-preserving verification
• Cryptographic proof confirms verification status without revealing identity data
• Selective disclosure via viewing keys for auditors and compliance teams

Aztec's privacy architecture:

• zkSNARKs (Honk) with UTXO model and hybrid public/private state
• Programmable privacy across data, identity, and compute
• Configurable per-function visibility mixing public and private state
• Client-side proving through Private Execution Environment (PXE)
• Native account abstraction built into the technology

Inco's privacy architecture:

• FHE enabling computation on encrypted data without decryption
• TEE-based trust assumptions for hardware security
• Encrypted state storage directly onchain
• Programmable view access as an institutional privacy primitive
• NIST-approved post-quantum security standards

For enterprise settlement and payout workflows, Hinkal's approach delivers immediate confidentiality without requiring migration or new cryptographic paradigms. The technology works with existing stablecoin infrastructure on chains enterprises already use.

Multi-Chain Support: A Critical Enterprise Requirement

Enterprise treasury operations, PSP settlements, and payroll flows rarely exist on a single chain. Hinkal's multi-chain architecture provides a decisive advantage for organizations operating across blockchain ecosystems.

Hinkal multi-chain support:

• Ethereum, Solana, Tron, Polygon, Base, Arbitrum, Optimism, and additional EVM chains
• Single SDK integration works across all supported chains
• No fragmented tooling or separate deployments required
• Unified confidential settlement regardless of underlying blockchain

Aztec chain support:

• Ethereum rollup
• Requires bridging assets to Aztec environment
• Single-chain focus by design

Inco chain support:

• Base Sepolia testnet and Solana devnet currently
• Production chain support still developing
• Early-stage ecosystem expansion

For Payment Service Providers settling merchant funds across multiple chains or treasury teams managing multi-chain liquidity, Hinkal provides confidential settlement without chain fragmentation.

Integration Complexity and Time to Value

The integration experience determines how quickly enterprises can deploy confidential settlement capabilities.

Hinkal integration advantages:

• NPM SDK package for straightforward developer integration
• No smart contract modifications required for existing solutions
• Works with MetaMask, Coinbase Wallet, and any EVM-compatible wallet
• Zero recipient-side setup (funds arrive in existing wallets)
• Pendle Finance integration demonstrates plug-and-play deployment
• Integration timeline: Days, not months

Aztec integration requirements:

• Migration to Aztec rollup environment required
• Developers must learn Noir programming language
• Requires Aztec-compatible wallet infrastructure
• Sandbox environment for development testing
• Integration timeline: Weeks to months depending on complexity

Inco integration requirements:

• New chain integration process
• Solidity and Rust SDK with familiar tooling
• Hardhat, Foundry, and Anchor support
• Early-stage documentation and ecosystem
• Integration timeline: Weeks with ongoing platform development

Hinkal Pay exemplifies this frictionless approach. Any transfer becomes a confidential transaction without exposing balances, counterparties, or wallet history. Recipients connect their existing wallet and see the confidential balance immediately.

Compliance-Ready Architecture for Institutional Adoption

Regulated enterprises require confidential settlement solutions that support auditability and regulatory compliance. Hinkal's compliance-first design differentiates it from purely cryptographic privacy approaches.

Hinkal compliance features:

• KYT enforcement via Chainalysis blocks flagged wallets at the deposit step
• Selective disclosure through viewing keys reveals transaction history to auditors, regulators, or compliance teams
• Integrity Check for transactions over $10,000 uses zero-knowledge proofs (Hinkal receives only cryptographic confirmation, never personal documents)
• Custom pool deployments with configurable compliance logic for heavily regulated entities
• Optional master-key visibility for institutional oversight requirements

Aztec compliance approach:

• Selective disclosure primitives available within the technology
• Programmable privacy allows configurable visibility
• Compliance logic must be built into custom implementations

Inco compliance approach:

• Programmable view access for institutional privacy requirements
• Configurable encryption key management
• Compliance frameworks still developing with the platform

For compliance officers managing regulatory exposure on-chain, Hinkal provides enterprise-ready auditability while maintaining operational confidentiality from competitors and market observers.

Enterprise Use Cases: Payments, Payroll, and Treasury Confidentiality

Hinkal serves specific institutional use cases where on-chain transparency creates competitive and operational risks.

Payment Service Providers: PSPs settling merchant funds on public chains expose merchant economics, counterparty relationships, and operational patterns. Hinkal's SDK integration sends funds to a merchant's confidential balance inside the smart contract. Merchants connect their existing wallet (no merchant-side integration required).

Payroll and HR Platforms: Companies running crypto payroll expose headcount, pay cycles, salary costs, and contractor relationships. Hinkal routes salary through its smart contract so sender and amounts stay confidential. Employees receive funds on their existing wallet with zero recipient-side setup.

OTC Desks: OTC desks settling large bilateral trades expose trade volume, wallet patterns, and counterparty relationships. Hinkal routes funds to a counterparty's confidential balance. Counterparties connect their existing wallet to access funds.

Treasury Operations: Treasury teams moving capital and rebalancing liquidity broadcast strategy and counterparties when operating on transparent chains. Hinkal enables confidential treasury flows without changing custody arrangements.

Hinkal Wallet provides continuous confidentiality for all account activity, maintaining a persistent confidential account while enabling swaps and transfers across chains.

Why Hinkal is The Best Alternative for Confidential Computing

For enterprise decision-makers evaluating confidential computing solutions, Hinkal provides compelling advantages across the dimensions that matter most for production deployment.

Multi-chain universality: Hinkal works across Ethereum, Solana, Tron, Polygon, and additional chains without requiring separate deployments or fragmented tooling. This matches how enterprises actually operate (across multiple blockchain ecosystems simultaneously).

Zero-friction integration: The SDK approach enables confidential settlement without smart contract modifications, custody changes, or wallet migrations. Existing infrastructure works immediately.

Recipient-side simplicity: The other party does not need to be a Hinkal user in advance. They connect their existing wallet and the confidential balance appears. This "one button, frictionless flow" applies across PSP settlements, employee payroll, OTC counterparty settlement, and more.

Compliance-ready architecture: Built-in KYT enforcement, viewing keys, and custom pool deployments satisfy institutional compliance requirements while maintaining confidentiality from competitors and market observers.

Production-proven reliability: $400M+ in volume processed and 6 security audits demonstrate enterprise-grade reliability.

Aztec's programmable privacy serves developers building entirely new private applications from scratch. Inco's FHE technology enables novel encrypted computation use cases. But for enterprises requiring confidential settlement and payout workflows on their existing chains and wallets today, Hinkal represents the superior choice.
