[Pass Club](https://stake.passtoken.org/) is the rewards and membership network that [Blockpass](https://www.blockpass.org/) (the KYC and identity-verification provider founded by Adam Vaziri) built around its $PASS token on BSC. PASS tokens are unusual. They're "KYC tokens," so transferring them requires the holder to complete a Blockpass KYC check, and they buy a discount on Blockpass's verification services. The native loyalty design ties identity, compliance, and rewards into a single asset.

Holdex came in to extend that design with a Uniswap V3 staking program — one tightly-scoped deliverable. The staking infrastructure and the dApp interface that didn't exist as a Uniswap-native primitive.

## What we shipped

Pass Club engaged Holdex to design a strategy for token-price growth and user acquisition. The conclusion was Uniswap V3 staking with a custom front-end. As Holdex's case study notes, Uniswap didn't provide any dApp interface to interact with their staking smart contracts. Holdex deployed the staking contracts on Uniswap V3 and built a custom React dApp at [stake.passtoken.org](https://stake.passtoken.org/) that matched Pass Club's design while delivering the familiar DeFi UX users expected.

The supporting Holdex content lives on holdex.io as a side effect: the Uniswap V3 staking deep-dive, the how-to-build guide, and the user walkthrough. The work for Pass Club became Holdex's canonical reference for Uniswap V3 staking integrations.

## The story

The PASS Liquidity Mining Initiative ran originally on the USDT/PASS Uniswap V2 pool from February 2021 onward, with the V3-era infrastructure shipping in 2023. The work for Pass Club became Holdex's canonical reference for Uniswap V3 staking integrations: strategy, contracts, and a custom dApp where Uniswap did not provide a finished staking interface.
