Testnet privacy bridge
Move USDC privately. Settle with proof.
A proof-backed EVM to Stellar relay for private-pool settlement without public transaction sprawl.

Private settlement
Built for proof-backed movement, not crypto theater.
The interface follows the real system boundary: prepare a note, lock source funds, produce a proof, claim on Stellar, and withdraw without dragging public transaction context along for the ride.
Proof privacy
RISC Zero binds the source lock to a private-pool claim without exposing sender history.
Deterministic routing
Intent IDs, commitments, CCTP fees, and replay checks stay verifiable from lock to claim.
User-owned notes
The user signs the EVM lock and controls the Stellar note keys. Nebula coordinates settlement.
Network posture
One relay surface. Multiple trust boundaries.
Nebula presents a narrow, operational interface over EVM locks, CCTP settlement, RISC Zero proving, and Stellar private-pool claims.

Execution flow
Every step maps to backend state. Operators and users can see what is pending, what is proven, and what is ready to withdraw.
Four controlled actions. One private result.
Prepare
Generate a private-pool output for the connected Stellar wallet.
Lock
Approve and lock USDC from the source EVM wallet.
Prove
Build the witness and proof artifact against the live intent.
Settle
Claim privately on Stellar, then withdraw when ready.
Bridge into a private note.
Connect EVM and Stellar wallets, prepare the proof, and submit the source-chain lock from a single production flow.
