About NodeMeta NodeMetais a Web3 ecosystem built on BNB Smart Chain, founded in August 2025 by SohelMazumder. We're not building another copy-paste DeFi fork — we're creating realproducts that connect blockchain utility to everyday use cases.
Ournative token NTE (Node Meta Energy) is live on BNB Smart Chain with a cappedsupply of 11 billion tokens and a 10-year halving strategy. The mining andstaking ecosystem is already operational, with users earning daily rewardsthrough our decentralized node-based infrastructure.
Wewere recognized as the BestDecentralized Ecosystem at the 2025 Evergreen Awards — and now we'rebuilding the team to deliver on the next phase.
What We're Building — Product Development Status NodeMetais developing four interconnected products. Here's what's live, what's inactive development, and where this role fits in:
Mining Staking Ecosystem
Status: LIVE ✓
Thefoundation of NodeMeta. Users participate in a decentralized node-based miningsystem and earn daily NTE rewards. The staking smart contracts are deployed onBSC mainnet and operational. This is the revenue-generating backbone of theecosystem — real users, real tokens, real on-chain activity.
Your involvement: Maintain, optimize, and extendexisting staking contracts. Improve gas efficiency and prepare for the nextphase of staking features (NFT-based staking, tiered reward structures).
NFT Marketplace
Status: IN ACTIVE DEVELOPMENT — architecturephase
Adecentralized marketplace for NFTs with a differentiator: real-world utility.NFTs on our platform aren't just collectibles — they unlock benefits, access,and rewards within the NodeMeta ecosystem. The marketplace will supportminting, listing, bidding, trading, and on-chain staking of NFTs withper-second reward accrual.
Your involvement: This is the core of your role.You'll design and implement the marketplace smart contracts from scratch —BEP-721/BEP-1155 minting, trading/auction logic, and the NFT staking engine(reward calculation, lock-up periods, safe withdrawal flows). You'll own thecontract architecture.
SmartCommerce
Status: IN DEVELOPMENT — design phase
Aplatform where users spend NTE tokens on real digital and physical goods —bridging blockchain and everyday commerce. This is what makes NodeMetadifferent from most Web3 projects: we're building actual utility for the tokenbeyond speculation. SmartCommerce requires on-chain payment contracts,settlement logic, escrow mechanisms, and integration points with off-chainfulfillment systems.
Your involvement: Design the on-chain payment andsettlement contracts. Build the escrow logic that protects both buyers andsellers. Work closely with the backend team to ensure on-chain payments triggerreal-world fulfillment reliably.
GreenCommerce
Status: PLANNED
Anexclusive marketplace for environmentally friendly products — eco-consciouselectronics, reusable home products, green building materials, and clean energysolutions. GreenCommerce will share the SmartCommerce contract infrastructurewith additional sustainability-focused features.
Your involvement: Future phase. Contracts you buildfor SmartCommerce will be extended for GreenCommerce, so your architecturaldecisions now directly shape this product.
What You'll Do Asour Solidity Smart Contract Developer, your day-to-day work spans three productareas:
NFT MarketplaceContracts ▸ Designand implement NFT minting contracts (BEP-721 and BEP-1155) ▸ Buildtrading logic — listings, bids, auctions, direct sales with escrow ▸ Implementthe staking engine — per-second reward accrual, lock-up periods, safewithdrawal with reentrancy protection ▸ Designthe reward token distribution mechanism for staked NFTs
SmartCommerce PaymentContracts
▸ Buildon-chain payment acceptance and validation logic
▸ Designescrow contracts for buyer/seller protection
▸ Security-firstculture — webudget for audits and take them seriously
▸ Small, focused team — your voice mattersin every architectural decision
▸ Sustainabilitycommitment — carbonneutrality pledge by 2030, investing in renewable energy projects
