Security

Hawasium's security model prioritizes deterministic behavior, non-custodial operations, and transparent architecture design.

Security Philosophy

Non-Custodial by Design

The architecture eliminates custody risk through design. No component requires transfer of signing authority or asset custody. All operations maintain user sovereignty throughout execution.

Deterministic Execution

All operations produce predictable, verifiable outcomes. State transitions follow deterministic paths that can be independently verified through on-chain program logic and transaction history.

Transparent Architecture

System design emphasizes transparency and auditability. All critical operations occur on-chain with public verification. No hidden processes or opaque execution paths.

Threat Model

The security model addresses threats through architectural design and operational constraints.

Smart Contract Vulnerabilities

Threat: Implementation errors, logic flaws, or unforeseen edge cases in on-chain programs.

Mitigation: Comprehensive testing, formal verification where applicable, external security audits, and bounded operation parameters.

Economic Attacks

Threat: Manipulation of liquidity pools, flash loan attacks, or price oracle manipulation.

Mitigation: Time-weighted price feeds, execution bounds, liquidity depth requirements, and operational monitoring.

Network-Level Attacks

Threat: Transaction censorship, network congestion, or validator collusion.

Mitigation: Dependence on Solana's validator set security. Priority fee mechanisms for critical operations. No off-chain dependencies for core functionality.

Integration Risks

Threat: Vulnerabilities in integrated external systems or protocols.

Mitigation: Minimal external dependencies, defensive integration patterns, explicit trust boundaries, and isolated failure domains.

Security Assumptions

The security model relies on explicit assumptions about underlying systems and cryptographic primitives.

Solana Runtime Security

Assumes correct operation of Solana's runtime environment including account isolation, program execution sandboxing, and rent mechanics.

Cryptographic Primitives

Relies on standard cryptographic operations provided by Solana runtime. No custom cryptography implemented.

Validator Set Security

Depends on Solana's validator decentralization and consensus security. No additional trust assumptions beyond base layer.

Client-Side Security

Users responsible for private key security and transaction signing. Infrastructure does not handle key management.

Security Non-Goals

Explicit limitations of the security model that integrators must understand.

Market Risk Protection

Does not protect against general market volatility or external economic conditions.

User Error Prevention

Does not prevent user errors in transaction construction or parameter selection.

Regulatory Compliance

Does not enforce jurisdiction-specific regulatory requirements. Integrators responsible for compliance.

Privacy Guarantees

All operations occur on public blockchain. No privacy features beyond base layer pseudonymity.

Responsible Disclosure

Security researchers are encouraged to report vulnerabilities through responsible disclosure practices.

Reporting Process

Security issues should be reported to security@hawasium.io with detailed information about the vulnerability, steps to reproduce, and potential impact assessment.

Response Timeline

Initial response within 48 hours. Severity assessment and remediation plan within 7 days for critical issues. Public disclosure coordinated after patches deployed.

Scope

On-chain programs, SDK implementations, infrastructure components, and integration interfaces are in-scope. Documentation issues and theoretical attacks without exploitation paths are out-of-scope.
