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 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. Older incentive designs often required fully transferring the liquidity position to an external contract; that pattern 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
