Subscribers

This page describes subscribers in the current FewToken + Uniswap v4 integration environment. It should be read as integration guidance, not as documentation for a separate native Ring v4 AMM.

Subscribers in this v4 integration stack allow liquidity-position owners to opt in to a contract that receives notifications. The new design is intended to support liquidity mining, additional rewards given to in-range liquidity providers. Through notification logic, position owners do not need to risk their liquidity position and its underlying assets. In Uniswap v3-style concentrated-liquidity systems, liquidity mining was supported by fully transferring the liquidity position to an external contract; this old design would give the external contract full ownership and control of the liquidity position.

When a position owner subscribes to a contract, the contract will receive notifcations when:

  • The position is initially subscribed

  • The position increases or decreases its liquidity

  • The position is transferred

  • The position is unsubscribed
