Staking Contracts

This package implements the stake-based liquidity incentives defined by ZEIP-31.

See the specification here.

Contracts Directory Structure

The contracts can be found in contracts/src.

* Staking.sol        | This is a stateless contract that encapsulates all the staking logic.
* StakingProxy.sol   | This is a stateful contract that proxies into the Staking contract.
* ReadOnlyProxy.sol  | This is a stateless contract the makes read-only calls from the Staking Proxy to the Staking Contract.
* fees/              | This contains mixins that implement the logic for 0x Protocol fees.
* immutable/         | This contains mixins that are generally immutable. Changing these files can result in catastrophic failures. Exercise extreme caution.
* interfaces/        | This contains interfaces used throughout the entire staking system.
* libs/              | This contains libraries used by the staking contract; for example, math and signature validation.
* stake/             | This contains mixins that implement the core staking logic.
* staking_pools/     | This contains mixins that implement logic for creating and managing staking pools.
* sys/               | This contains mixins that implement system-level functionality, like scheduling and finalization.
* vaults/            | This contains the vaults (like the Zrx Token Vault).
