HungryBera NFT & Lottery
Berachain-Native NFT with DeFi Lottery Integration
HungryBera is the flagship NFT collection of the Ramen Finance ecosystem, deployed on Berachain. The Next.js frontend uses Tailwind CSS for styling, ConnectKit for wallet connection, and viem with Wagmi for modern EVM interactions and Next-Auth for session management. The Solidity contracts use ERC-721A with @sigpub/signatures-verify for signature-based minting, closedsea for operator filtering, and Merkle tree allowlists. The Go backend handles off-chain operations including metadata and lottery draw mechanics.

Engineered the full NFT infrastructure: Next.js frontend with ConnectKit and viem/Wagmi for Berachain interactions, Go backend for metadata and lottery operations, and Solidity contracts with ERC-721A, @sigpub/signatures-verify integration, and closedsea operator filtering. Built the lottery draw mechanism as a separate system connected to the NFT ecosystem.
