# Smart contracts

Our contracts were built on OpenZeppelin technologies. We used OpenZeppelin library for secure smart contract development. These contracts were built on a solid foundation of community-vetted code.

You can find OpenZeppelin library detailed description [here](https://docs.openzeppelin.com/contracts/4.x/).

Actual library source is available on [github](https://github.com/OpenZeppelin/openzeppelin-contracts/).

WAO DAO token contract ([ERC20 standart](https://ethereum.org/en/developers/docs/standards/tokens/erc-20/)): [0xc3ad687c8ecb352d56393c77d19018b93a6ad21a](https://etherscan.io/token/0xc3ad687c8ecb352d56393c77d19018b93a6ad21a) You can find contract technical description [here](https://docs.openzeppelin.com/contracts/4.x/erc20).

WAO DAO NFT contract ([ERC721 standart](https://eips.ethereum.org/EIPS/eip-721)): [0x3b9a62c6dd4d93f8a6fa4a350da32d28fac80863](https://etherscan.io/token/0x3b9a62c6dd4d93f8a6fa4a350da32d28fac80863) You can find contract technical description [here](https://docs.openzeppelin.com/contracts/4.x/erc721).

For Treasury management we use [Gnosis safe](https://gnosis-safe.io/) smart contracts with 2/4 signatures threshold. 

Our Ethereum Gnosis safe: [0x6551DA3a016eE12a14aE4435B615222d71BEA778](https://etherscan.io/address/0x6551da3a016ee12a14ae4435b615222d71bea778)
