Introduction
The Scaffold HBAR Template Bounty is closed and the judging panel has chosen its winners. Each team wins $2000 in HBAR. These templates are educational starting points. They are unaudited, testnet only, and not financial advice.
The winners
Hedera Governed Operations by SpaceDev
github.com/SpaceUY/hedera-governed-operations
Hedera Governed Operations lets a council approve sensitive operations using Hedera’s native multisig from an account’s threshold key. Each proposal is a scheduled transaction the network executes once enough members sign, with no multisig contract.
npm create scaffold-hbar@latest my-app -- --template SpaceUY/hedera-governed-operations
SaucerSwap Limit Orders by Jagadeesh
github.com/Jagadeeshftw/saucerswap-limit-orders
SaucerSwap Limit Orders is price-triggered: users lock tokens in an on-chain vault and set a price, and the Schedule Service re-schedules the vault’s own checks, so no off-chain keeper runs.
npm create scaffold-hbar@latest my-app -- --template Jagadeeshftw/saucerswap-limit-orders
Custos by Victor Jayeoba
github.com/victorjayeoba/scaffold-hbar-custos
Custos demonstrates scheduled liquidation checks for a leveraged trading contract. Every 30 minutes the Schedule Service calls the contract, which liquidates underwater positions and books its own next run. It runs a Chainlink and Supra dual-oracle guard that refuses a stale price or one more than 5% apart.
npm create scaffold-hbar@latest my-app -- --template victorjayeoba/scaffold-hbar-custos
Recurring Buy by RetailBox
github.com/retailbox-automation/recurring-buy
Recurring Buy is time-triggered: it buys a token on SaucerSwap on a schedule such as hourly or weekly, with no bot or server. It includes a front end for setting up and managing schedules.
npm create scaffold-hbar@latest my-app -- --template retailbox-automation/recurring-buy
Predera by Manish Shivabhakti
github.com/superhbar/prediction-market
Predera is a template demonstrating scheduled settlement for price prediction markets, and the contract books its own settlement through the Hedera Schedule Service. It reads Chainlink price feeds with Pyth as a fallback, and YES/NO positions are HTS tokens that trade on SaucerSwap before settlement.
npm create scaffold-hbar@latest my-app -- --template superhbar/prediction-market
