Could you build this?
Partial While the front-end swipe UI is easy to vibe code, building secure non-custodial smart contracts, gasless meta-transactions (ERC-4337 Account Abstraction), and financial settlement mechanisms requires specialized Web3 auditing.
What it would actually take: The stack would include ERC-4337 smart contracts on an EVM L2 (e.g., Base or Arbitrum), a bundler/paymaster infrastructure (like Biconomy or Pimlico) for gasless trading, and automated settlement liquidity pools. The hard part is preventing smart contract exploits, race conditions on 24-hour pool closures, and handling regulatory compliance for prediction/opinion betting markets.
