OpenZeppelin stdlib · ZeppelinOS

ZeppelinOS provides a way to link your contracts to on-chain standard libraries of reusable code.

One such library is the OpenZeppelin stdlib, which includes some of the most widely used contracts. The code in this stdlib comes from OpenZeppelin, an extremely well-tested collection of smart contracts that were only slightly modified to adapt them to ZeppelinOS.

The contracts presently included in the OpenZeppelin stdlib are:

DetailedMintableToken
DetailedPremintedToken
MintableERC721Token
TokenTimelock
TokenVesting
SplitPayment

The source code for these contracts can be found in the zos-release branch of the OpenZeppelin/openzeppelin-solidity repository.
