Introduction
🎯 Project Overview
Lotellar is a decentralized lottery platform built on the Stellar blockchain. It allows users to join fair, transparent lotteries and enables other Web3 projects to create reward-based campaigns using their own tokens.
❗ Problem
There is no trustless, decentralized lottery system on Stellar. Current solutions are centralized, non-transparent, and don't support community-driven growth for ecosystem projects.
✅ Solution
We’re building an on-chain lottery mechanism that:
Selects winners using VRF (Verifiable Random Function)
Lets users join lotteries by paying a fixed fee
Automatically creates a new lottery when one ends
Enables other projects to create token-gated lotteries with custom rules and rewards
🧩 How It Works
A lottery is initialized with parameters: entry fee, number of participants, reward
Users join by paying the entry fee
Once the trigger condition is met (e.g. user limit or time), the winner is selected via VRF
The reward is sent on-chain
A new lottery is auto-generated
Projects can create lotteries requiring token ownership (e.g. “Hold 10 XYZ tokens to join”)
