Contract Standards¶
Standard interfaces and patterns for Koinos smart contracts.
Overview¶
Contract standards ensure interoperability between different applications and provide consistent interfaces for common functionality.
Token Standards¶
KCS-1: Fungible Tokens¶
- Purpose: Standard interface for fungible tokens
- Functions: transfer, balanceOf, totalSupply, approve, allowance
- Usage: Most tokens follow this standard for compatibility
KCS-2: Non-Fungible Tokens (NFTs)¶
- Purpose: Standard interface for unique digital assets
- Functions: ownerOf, transferFrom, approve, tokenURI
- Usage: NFT collections and marketplaces
DeFi Standards¶
KCS-3: Decentralized Exchange¶
- Purpose: Standard interface for DEX contracts
- Functions: addLiquidity, removeLiquidity, swap
- Usage: Trading platforms and aggregators
KCS-4: Staking Contracts¶
- Purpose: Standard interface for staking mechanisms
- Functions: stake, unstake, claimRewards, getStakeInfo
- Usage: Yield farming and staking platforms
Governance Standards¶
KCS-5: Governance Tokens¶
- Purpose: Standard interface for governance participation
- Functions: propose, vote, execute, getVotingPower
- Usage: DAO and governance systems
Best Practices¶
- Follow established standards for interoperability
- Implement proper interfaces for contract interactions
- Use consistent naming conventions
- Provide comprehensive documentation
- Test compatibility with existing tools
