Lock ETH in CollateralVault and submit your Spacecoin nodeId to NodeRegistry.
USC simultaneously attests your Deposited and NodeRegistered events. Takes 8–10 minutes.
SpaceFinance releases mUSDF to your wallet after both attestations confirm.
Repay your mUSDF loan at your dynamic rate based on node revenue.
Your repayment is published to CC3's Outbox, signed by USC attestors, and delivered to Sepolia's Inbox — authorizing the unlock automatically. No admin step required.
Repayment confirmed, ETH collateral returned to your wallet.
Powered by USC attestations, removing centralized oracles or bridges. Your collateral state is verified cryptographically by the network.
Your Spacecoin node's ReceiptClaimed revenue history on CC3 mainnet determines your credit limit — up to monthly average × 3, in addition to ETH collateral.
Join a 5-node GuildPool based on Grameen Bank's joint-liability model. Any default freezes the guild's borrowing. Members unlock collateral requirements as low as 5%.
