I’m taking our luxury-hotel brand on-chain and need an expert to build the complete tokenisation stack on Ethereum. The vision is to issue one flagship token that grows with every new property we open, beginning with a three-round sale in which the price automatically steps up at each phase. Core mechanics • ERC-20 (or equivalent) token deployed on Ethereum. • Crowdsale contract with three timed rounds and rising price per token. • Built-in utility: holders receive free-night stays proportionate to their ownership. • Dividend distribution function so a share of operating profit can flow directly to wallets. • Tiered, air-miles-style reward programme accrued on-chain and redeemable for extras and upgrades. • Optional, provably fair lottery that lets participants win complimentary stays. Deliverables • Audited smart-contract suite covering token, sale, rewards, dividends and lottery. • Migration scripts, tests and OpenZeppelin-based security patterns. • Admin functions for adjusting round dates, reward parameters and treasury wallet. • Lightweight web dashboard (React or similar) for KYC, purchase, balance and reward redemption. • Mainnet deployment, full documentation and a short knowledge-transfer session. Acceptance criteria • Contracts compile cleanly, pass unit tests and are verified on Etherscan. • Reward and dividend calculations are accurate to the smallest unit. • Lottery results are transparent and tamper-proof. • Gas consumption is optimised for frequent reward updates. If you’ve launched comparable crowdsales or hospitality utility tokens, send contract addresses or live links—real-world proof matters more to me than presentations. Timelines are tight, so include your development milestones and preferred workflow when you reply.
