# Klekshun: NFT mint, staking & mutation ecosystem

A three-collection NFT ecosystem on Polygon: mint, staking, raffles, and an on-chain mutation portal where apes drink serum and transform.

*2023 - present · ongoing, multiple phases*

## The brief

Klekshun runs three NFT collections on Polygon: Polygon Ape, Donsy and Polygon Mutant. We built the full technical infrastructure across multiple phases, starting with the minting pages and smart contracts for all three collections, then the whole utility layer that keeps holders engaged.

It is one of our longest-running client relationships, with continuous feature development since the first mint.

## What we built

- **Mint pages.** ERC-721A contracts for three collections
- **Staking system.** holders earn rewards
- **Raffle system.** holder-gated draws
- **Serum airdrop.** claim page for mutation serums
- **Mutation portal.** burn the serum, mint the mutant, one transaction
- **PFP generator.** for all three collections
- **Ape Checker.** traits and ownership verification

## How it works

The mutation flow chains burn and mint into a single transaction, and the whole utility layer (stake, claim, burn, mint) is composed so each interaction stays cheap on Polygon and smooth for the user.

## Stack

- **Stack:** Next.js, Solidity (ERC-721A), Polygon

## The hardest part

Chaining multiple smart contract interactions into smooth single-step experiences while keeping gas costs low.
