Welcome to Zeppelin-Solidity

Zeppelin is a library for writing secure Smart Contracts on Ethereum.

With Zeppelin, you can build distributed applications, protocols and organizations:

• using Common Contract Security Patterns
• in the Solidity language.

The code is open-source, and available on github.

  • Truffle Beta Support

Smart Contracts

• Ownable
  • Ownable( )
  • modifier onlyOwner( )
  • transfer(address newOwner) onlyOwner
• Stoppable
  • emergencyStop( ) external onlyOwner
  • modifier stopInEmergency
  • modifier onlyInEmergency
  • release( ) external onlyOwner onlyInEmergency
• Killable
  • kill( ) onlyOwner
• Claimable
  • transfer(address newOwner) onlyOwner
  • modifier onlyPendingOwner
  • claimOwnership( ) onlyPendingOwner
• Migrations
  • upgrade(address new_address) onlyOwner
  • setCompleted(uint completed) onlyOwner**
• SafeMath
  • assert(bool assertion) internal
  • safeMul(uint a, uint b) internal returns (uint)
  • safeSub(uint a, unit b) internal returns (uint)
  • safeAdd(unit a, unit b) internal returns (uint)
• LimitBalance
  • LimitBalance(unit _limit)
  • modifier limitedPayable()
• PullPayment
  • asyncSend(address dest, uint amount) internal
  • withdrawPayments( )
• StandardToken
  • approve(address _spender, uint _value) returns (bool success)
  • allowance(address _owner, address _spender) constant returns (uint remaining)
  • balanceOf(address _owner) constant returns (uint balance)
  • transferFrom(address _from, address _to, uint _value) returns (bool success)
  • function transfer(address _to, uint _value) returns (bool success)
• BasicToken
  • balanceOf(address _owner) constant returns (uint balance)
  • function transfer(address _to, uint _value) returns (bool success)
• CrowdsaleToken
  • createTokens(address recipient) payable
  • getPrice() constant returns (uint result)
• Bounty
