Given the limitation of smart contracts, they are not self-executing, and require an external force to trigger their functions. Relay is a service to drive LRT network to properly process its own internal states, such as dealing with delegating, undelegating, distributing rewards and calculating the rate between LRT and LST. We introduce era
concept to define how often the smart contract should be called. Most of the time, an era is 24 hours long.
Security is the our first priority when developing Stack, We are thrilled to say that the new era process is permissionless, showcasing the decentralized nature of the StaFi LRT Stack, allowing anyone to trigger the beginning of a new era.
