# Smart Contracts

**Governor (**[0x1D734e5de4c4a4b70538Bb52D9A08a8E9468b26f](https://etherscan.io/address/0x1D734e5de4c4a4b70538Bb52D9A08a8E9468b26f))

The contract that governs the protocol through voting. It can push proposals and apply changes through the timelock contract.

**Timelock** ([0x60944aFF520C44Df6d877aE379aBB7Aa704b0b8F](https://etherscan.io/address/0x60944aFF520C44Df6d877aE379aBB7Aa704b0b8F))

This is the administrator of all other contracts and is managed by the Governor contract. For security purposes, code changes have a deferral period. The default deferral period is fixed at 5 days ( 120 hours). This period can change through governance voting.

**Router** ([0x463672ffdED540f7613d3e8248e3a8a51bAF7217](https://etherscan.io/address/0x463672ffdED540f7613d3e8248e3a8a51bAF7217))

This facilitates interaction with smart contracts, allowing references to functions of the code as domain names.

**Factory** ([0x69bd16aE6F507bd3Fc9eCC984d50b04F029EF677](https://etherscan.io/address/0x69bd16aE6F507bd3Fc9eCC984d50b04F029EF677))

Creates new pairs and includes the Protocol Fee switch (which sends 0.05% to the FeeTo address).

**Controller (**[0xA9229c9D3720CD359cEc51A259003C845E4C8224](https://etherscan.io/address/0xA9229c9D3720CD359cEc51A259003C845E4C8224))

Allows updating of the pairs code.

**Escrow** ([0x39D34833d45A973e80D66E07E93512a8c508372C](https://etherscan.io/address/0x39D34833d45A973e80D66E07E93512a8c508372C))

Issues governance tokens into circulation according to the established schedule.

A smart contract that provides a reward for staking LP tokens in governance tokens.
