Supported Platforms

Odin Scan supports multiple blockchain platforms including Cosmos SDK modules, CosmWasm, EVM, and Solana. Each platform has dedicated analysis logic and platform-specific rules.

Cosmos SDK & CosmWasm

Odin Scan provides comprehensive support for both Cosmos SDK Go modules and CosmWasm smart contracts.

CosmWasm (Rust)

Language: Rust Ecosystem: Cosmos SDK chains (Osmosis, Neutron, Terra, Injective, Juno, etc.)

Detection

Odin Scan identifies CosmWasm projects by checking for cosmwasm-std in Cargo.toml dependencies.

Analysis Features

• Entry point analysis (instantiate, execute, query, migrate, sudo)
• State management validation (storage reads/writes, key collision detection)
• Access control checks on privileged operations
• Cross-contract message handling and reply safety
• IBC entry point validation
• Addr::unchecked() usage detection
• Unsafe arithmetic operation detection
• Deterministic static analysis rules (8+ Rust-specific rules)

Common Vulnerability Patterns

• Missing access control on execute handlers
• Unsafe math operations without overflow protection
• Unvalidated addresses passed to contract state
• Storage key collisions between different state items
• Unbounded iteration over state maps

Cosmos SDK Go Modules

Language: Go Ecosystem: Cosmos SDK blockchain modules and custom applications

Detection

Odin Scan identifies Cosmos SDK Go projects by checking for Go module patterns and cosmossdk.io dependencies.

Analysis Features

• Gosec static analysis for Go security
• Message handler validation
• Permission and authorization checks
• Go-specific security patterns

Common Vulnerability Patterns

• Missing permission checks on sensitive operations
• Unvalidated external input
• Insecure cryptographic operations
• Insufficient error handling
• File permission issues

EVM

Languages: Solidity, Vyper Ecosystem: Ethereum, Arbitrum, Optimism, Base, Polygon, BSC, Avalanche, and all EVM-compatible chains

Detection

Odin Scan identifies EVM projects by the presence of .sol files combined with framework configuration:

• foundry.toml (Foundry)
• hardhat.config.js or hardhat.config.ts (Hardhat)

Analysis Features

• Multi-agent AI analysis with EVM-specific rules
• Solidity compiler version detection and version-specific checks
• Reentrancy detection across external calls
• Storage layout analysis
• Access control and authorization pattern checks
• ERC standard compliance verification

Common Vulnerability Patterns

• Reentrancy via external calls before state updates
• Integer overflow/underflow in older Solidity versions
• Unprotected selfdestruct or delegatecall
• Front-running and MEV exposure
• Flash loan attack vectors
• Missing input validation on public functions
• Storage collision in proxy/upgrade patterns

Solana (SVM)

Language: Rust Ecosystem: Solana

Detection

Odin Scan identifies Solana projects by:

• Anchor.toml and programs/ directory (Anchor framework)
• Native Solana program structure with solana-program dependency

Analysis Features

• Account validation and ownership checks
• Signer verification analysis
• PDA (Program Derived Address) derivation correctness
• CPI (Cross-Program Invocation) safety
• Anchor constraint validation (has_one, constraint, seeds)
• Rent-exemption and account lifecycle checks

Common Vulnerability Patterns

• Missing signer checks on privileged instructions
• Incorrect account ownership validation
• PDA seed collision or incorrect derivation
• Unsafe CPI without proper account validation
• Missing close account cleanup (leaving rent behind)
• Type confusion between account structures

Auto-Detection

By default, Odin Scan automatically determines the platform by examining the repository structure. The detection order is:

1. Check for Cosmos SDK markers (Go module with cosmossdk.io dependency)
2. Check for CosmWasm markers (cosmwasm-std dependency)
3. Check for EVM markers (.sol files with Foundry/Hardhat config)
4. Check for Solana markers (Anchor.toml or solana-program dependency)

If detection is ambiguous or the repository contains multiple platforms, you can specify the platform explicitly:

# In the GitHub Action
- uses: odin-scan/odin-scan-action@v1
  with:
    api-key: ${{ secrets.ODIN_SCAN_API_KEY }}
    platform: cosmos   # or: cosmwasm, evm, solana
