Build Sorphera smart contracts on Ethereum Sepolia.
Build Sorphera smart contracts on Ethereum Sepolia. Tagline: Weekly ETH & NFT lottery ball jackpots. Powered by FWA. Use Sorphera branding throughout. Deliver contracts, Foundry tests and docs; website later. No new ERC20 or liquidity pool. GAMES Sorphera ETH Jackpot and Sorphera NFT Jackpot each draw weekly (two draws total), with separate rounds, tickets, schedules and accounting. Each nontransferable ticket enters one game/round. Default: 0.005 Sepolia ETH. Players pick 3 distinct unordered numbers from 1-20 and 1 bonus from 1-5. Duplicate combinations and multiple tickets per wallet are allowed. Uncapped sales; bounded transaction batches. Configure seven-day windows, separate initial cutoffs and earliest draw-request times. Freeze price, fees, number format and deadlines before first sale; changes affect future rounds only. MONEY Split new sales: 10% operator fee, 90% round-specific FWA acquisition budget, including FWA acquisition/VRF charges. Operator resources separately fund lottery VRF and gas. Isolate fees, budgets, pending requests, refunds, carryovers and winner liabilities by game/round. No cross-subsidies or spending reserved assets. Charge fees once on new sales, never on prizes, refunds or carryovers. Builder rewards belong to the company. Purchaser rewards/refunds are prizes. Late recoveries follow the originating round's winner, rollover or refund entitlements. Operator withdrawals cannot consume player assets. FWA Verify Sepolia addresses, ABIs and dependencies using: [Sepolia](https://www.fwa.fun/docs/v2-sepolia) [Builder rewards](https://www.fwa.fun/docs/builder-revenue) [Settlement](https://www.fwa.fun/docs/winning) [Reference contracts](https://github.com/adamlizek/fwa-examples) Make a builder router the immediate caller of FWAV2.acquire and a separate prize vault the purchaser. Preserve builder attribution and purchaser rights. Read live quotes, fees, settings and settlement windows; never hardcode 0.06 ETH/spin. Enforce budgets, slippage limits and deadlines. Attribute all requests, allocations, settlements and recoveries to game/round. Recover expired requests and overpayments. Claim builder rewards only against actual allowances; assume no fixed emissions or guaranteed revenue. Permissionless settlement enforces the game's fixed outcome. Document keepers, deadlines, missed windows and pending delivery. Verify NFT custody, not just notifications. ETH JACKPOT Use its acquisition budget for FWA pulls; settle successful allocations to ETH. Prize = actual cashouts + unused budget + refunds + ETH carryover. Prize value is not guaranteed. After cutoff and reconciliation, draw numbers. Match all 3 main numbers and the bonus to qualify. One match wins everything. Multiple matches split equally per winning ticket, including repeats per wallet. No match rolls the prize into the next ETH round. Old tickets expire; never buy pulls with carryover. Use claim-based payouts, reserve unpaid winnings and carry division dust forward. NFT JACKPOT Use its acquisition budget for FWA pulls; always choose "keep the NFT" and secure assets promptly in the vault. No voluntary cashouts, sales, relisting, substitution or cherry-picking. Track collection, token ID, acquisition, round and custody. Use the same selected numbers and exact-match rule: - No match: roll all inventory and residual prize funds into the next NFT round; old tickets expire. - One match: that ticket wins all inventory and residual prize funds. - Multiple matches: uniformly select ONE matching ticket to win everything, using a domain-separated stream of verified round randomness. Each matching ticket has equal probability, including repeats per wallet. Disclose the tie-break. Add acquisitions to carryover; never respin or re-fee carryover. Freeze secured inventory before requesting lottery randomness. Allow individual/batched claims to the winner's nominated compatible recipient. Isolate transfer failures, prevent double claims and reserve unclaimed assets. Unexpected ETH recoveries remain incidental NFT-round prize funds; never label them NFTs or guarantee resale value. If no NFT, including carryover, is secured by the published settlement deadline, cancel BEFORE requesting lottery randomness. Refund available unspent/recovered funds plus reserved operator fees pro rata to ticket holders; preserve late-recovery entitlements. Do not guarantee full refunds after third-party charges/losses. Hold this round's operator fees until success/cancellation is established. RANDOMNESS AND REPLAY Use independent Chainlink VRF for lottery draws, separate from FWA randomness. Bind callbacks to game, round and request ID. Uniformly sample 3 distinct main balls and 1 bonus. Store ordered balls for replay and normalized combinations for matching. Close sales and reconcile required prize accounting before requesting randomness, never before the published earliest request time. Specify settlement/VRF delay handling. No rerolls, replacement requests, admin-selected results, post-cutoff purchases or outcome-dependent cancellation. Store randomness in callbacks; finalize and claim separately. Expose persistent state/events for schedules, closure, prizes, randomness, ordered results, match counts, tie-breaks, rollovers and claims for replay/reconnection. Frontend globe-ball animations show recorded results, never determine outcomes. Document that onchain results may be readable before animation ends; no secret per-ball releases. With zero tickets, skip randomness and retain carryover. SECURITY AND DELIVERY Index combinations/matching tickets so finalization and selection never scan all sales. Never require transferring the full NFT inventory in one transaction. Prevent reentrancy, stale/duplicate callbacks, double claims, rejected-transfer losses and cross-round accounting errors. Admins cannot seize prizes or change active-round rules. Pausing sales preserves claims. Test zero/one/multiple matches, duplicates, both rollovers, NFT tie-break, large ticket/inventory counts, failed acquisitions, delayed settlement, custody recovery, late refunds, partial claims, rounding and conservation of funds. Provide reproducible mocks and separate FWA Sepolia integration tests. Distinguish verified behavior, assumptions and mocks; never silently substitute mocks. Deploy with sales disabled until dependencies, configuration and randomness funding are validated. Export source, ABIs, addresses, deployment blocks, configuration and frontend interfaces; document setup, remaining dependencies and both lifecycles.
