Paygent V2

Paygent v2 is an onchain subscription payment protocol that vaults user funds, activates ENS-linked strategies, and deploys idle capital into DeFi liquidity before scheduled payments. It supports agent-driven and automated execution, allowing payments to be triggered permissionlessly when conditions are met.

Paygent is designed with a pluggable liquidity executor architecture. In this iteration, we explored Uniswap v4–based liquidity execution on testnets by implementing a dedicated Uniswap v4 executor that interacts directly with the v4 PoolManager. Due to current testnet constraints around pool initialization, this execution path is demonstrated and developed on a separate branch, while the core protocol remains stable and deterministic. This design intentionally decouples payment logic from liquidity strategies, enabling future deployments to route idle capital through Uniswap v4 or other DeFi primitives as testnet and mainnet infrastructure matures.

Paygent v2 is built with a modular Solidity architecture: a PaymentManager vault controls user funds and ENS-linked strategies, executor contracts handle DeFi interactions, and a Chainlink-style automation layer triggers payments. Foundry scripts manage deployment and testing on Sepolia.
