We delivered a modular TypeScript/Node backend that powers a wallet‑based Bitcoin‑rewards platform:
Auth & Wallets: non‑custodial login and session handling for EVM and Bitcoin addresses.
Game Engines: daily “Satoshi Mining,” provably‑fair “Spin‑to‑Win,” and concurrency‑safe “Predict the Block,” each publishing on‑chain events and leaderboards.
NFT Layer: ERC‑721 mint‑and‑verify flow that unlocks VIP games via referral‑coded NFT drops.
Payout Service: batch‑transaction engine that converts in‑game sats to real BTC and automates withdrawals.
Trophy Room & Scoreboard: fetches user NFTs, tracks redeemed rewards, and aggregates all game stats for a global ranking API.
Everything exposes clean REST endpoints for front‑end or partner integrations while keeping private keys strictly client‑side.
We engineered Mothership Blockchain Bots, a four‑part automation suite that powers a non‑custodial launchpad:
Escrow Bot securely pools presale funds in isolated smart‑contract escrows, auto‑refunding contributors if targets aren’t met.
Token Launch Bot converts successful escrows into fully deployed tokens, seeding liquidity and enforcing anti‑sniping, lock‑period, and allocation rules.
Airdrop Bot lets admins distribute tokens to curated wallet lists with custom formulas, ensuring transparent on‑chain proofs.
Wallet Control Bot treats multiple wallets as one treasury, executing batched buys, sells, and transfers across EVM and Solana accounts from a single command queue.
Role‑based REST endpoints and event logs give builders an easy integration path while keeping all private keys client‑side, delivering a secure, flexible backbone for multichain project launches.
We delivered a decentralized AI‑governance protocol for Zuvu, anchored by upgradeable smart‑contract modules:
Governance Contract: weighted‑median voting where staker‑backed top governors steer token minting and treasury allocations.
Upgradeable ERC‑20 Token: on‑chain monetary‑policy lever that supports future economic tweaks without redeploying.
Ensemble Registry: maintains a verifiable roster of contributors/ensembles, enabling direct, rule‑based fund distribution.
Proxy Architecture & Events: modular upgrade paths and rich event logs ready for analytics and off‑chain indexing.
We leveraged LayerZero technology to enable multichain functionality for Vana token. Now it supports multiple networks, including Ethereum, Arbitrum, Optimism, and Base, ensuring seamless interoperability and broader accessibility.
We engineered the entire LITAS blockchain ecosystem—from core infrastructure to user‑facing tools—in one cohesive package:
Exchange Platform: multi‑chain DEX with hybrid order‑book + AMM trading, on‑chain swaps, and real‑time price feeds.
Non‑custodial Wallet: web/mobile wallet featuring multisig support, hardware‑wallet integration, and seamless cross‑chain bridges.
Product Design: complete brand identity, design system, and responsive UI for every LITAS application.
Tokenomics Suite: supply‑curve modeling, vesting and staking contracts, plus analytics dashboards for emission tracking.
We built a website with NFT minting functionality, fully integrated with the custom Kroma network to support scalability and smooth transactions. We also handled Web3 architecture and third-party integrations for their gaming platform.
We created an ERC721 minting smart contract with a referral system that rewards users for promoting NFTs and the project. The contract also includes a random minting feature to prevent sniping. In addition, we developed a fast-paced PvP shooting game where NFTs are used as player characters, adding customization and ownership to the gameplay experience.
We developed a suite of smart contracts, including an ERC721 minting contract with three minting methods. We also created a minting contract for a new NFT collection using reward payments and an ERC20 contract with staking features. Partnering with Chainlink, we implemented a randomized ERC721 minting process to ensure fairness and security, preventing sniping.
