Live on Ethereum Sepolia + Stellar testnet

Lock collateral, prove it privately, and borrow USDC.

Connect both wallets, lock your own test ETH on Ethereum, then let a zero-knowledge proof unlock real Circle USDC on Stellar. Every action here is a real transaction you sign. Your collateral amount never leaves your wallet view; proving runs off-chain and takes a few minutes.
