hip-1215

Hedera Schedule Service (HIP-1215) emulator on a pinned Hedera mainnet fork. Test contracts that schedule their own calls with real gas, fees, expiry and payer balance, against real SaucerSwap, Supra and HTS state. No mocks.

Cron for contracts on Hedera. A Scaffold-HBAR template where contracts book and pay for their own next run (HIP-1215), guarded by SaucerSwap V2 + Chainlink.

🔁 Renews an agent's API access on-chain: an x402-gated service on Hedera where the Hedera Schedule Service (HIP-1215, system contract 0x16b) calls the contract back at expiry, charges the next period and re-arms the next renewal. The agent pays once over x402; no user, server job or cron keeps it alive.

Custos — a margin engine the Hedera network keeps. Scaffold-HBAR template: liquidations and funding run by the Hedera Schedule Service (HIP-1215), priced by Chainlink and cross-checked by Supra. No keeper bots.
