Description
Syndicate: Pool Lottery Tickets, Increase Winning Odds Together
Syndicate enables users to form groups (syndicates) and pool their resources to purchase lottery tickets collectively, dramatically increasing their odds of winning. By combining tickets, members share prize winnings proportionally—making lottery participation more accessible and rewarding.
Key Features:
One-Click Permission Grant: Users approve recurring purchases once with granular limits (amount, duration, frequency)
Multi-Chain Support: Works across Ethereum, Base, Avalanche, Solana, Stacks, and NEAR
Secure Smart Sessions: Leverages ERC-7715 for scoped permissions that expire automatically
Scheduled Execution: Vercel Cron jobs trigger on-chain transactions at specified intervals
Database Persistence: Tracks donation records and permission validity
Progress During Hackathon
Current Implementation: Ticket Purchasing: Live on-chain ticket purchases across Ethereum, Base, Avalanche, Solana, Stacks, and NEAR Envio Indexing: Real-time event tracking and data indexing using Envio for reliable on-chain state management MetaMask Advanced Permissions (ERC-7715): Integrated framework for scoped, time-limited transaction permissions In Development: Smart Sessions: Building ERC-7715 smart session infrastructure to enable automated, permissioned transactions without manual approval Syndicate Formation: Users create or join syndicates around shared interests—whether financial optimization or social causes Altruism Integration: Users can harness collective participation to support charitable causes while increasing ticket volume and winning odds Cross-Chain Settlement: Coordinating syndicate purchases and prize distribution across multiple blockchain networks
