This repository contains the Solidity smart contracts implemented for the Liminal Games protocol, a crypto-native strategy game platform built on Ethereum Layer 2 (Base). It demonstrates a full on-chain architecture including presale contracts, staking systems, liquidity provisioning, token mechanics, game logic, and vesting infrastructure.

A Solidity smart contract that allows a single user to deposit ETH, which is locked until the total USD value (via Chainlink pricefeed) exceeds a preset threshold. Once withdrawn, the vault resets and becomes available for the next user.

Experience the future of decentralized finance. Stake your NECTR tokens to earn up to 15% APY rewardsand join the next generation of blockchain innovation.

A time-locked ETH deposit simulator that mimics a fixed-term savings account. Users can deposit ETH for a fixed duration and automatically receive principal + fixed interest at maturity. Payout automated with Chainlink's Upkeep.

Solidity smart contracts implementing an on-chain referral and commission distribution system deployed on Base Sepolia.

Solidity smart contracts implementing a soulbound identity and reputation system using non-transferable NFTs and tokens on Base Sepolia.

Solidity smart contracts implementing ERC-6551 token-bound accounts (NFT-controlled wallets) capable of holding ERC20, ERC721, and ETH assets.

Solidity smart contracts implementing a Chainlink VRF-powered lottery system deployed on Base Sepolia.

Solidity smart contracts implementing an NFT marketplace with ERC721 NFTs, ERC20 payments, royalties, and platform fees.

Solidity smart contracts implementing a configurable ERC20 team vesting and treasury vault system on Base Sepolia.
