OTC trading where your
book stays private.
Umbra lets institutions trade USDC and EURC in size without exposing amounts publicly. Agree on terms privately, settle on Arc, give your auditor a key.
Public chains have a position problem
The moment you put a large USDC order on the blockchain, every trader in the market sees it. That information moves prices before your trade settles. Umbra keeps the size hidden until both sides are already locked in.
How a trade works
You set the direction and the amount you want to trade. The size stays private. Your counterparty learns the details from you directly.
The other party accepts your quote and locks in at the rate you both agreed. Neither amount is visible to anyone else on the network.
Either party triggers settlement. Both sides are verified and the swap executes. No custody risk, no partial fills.
Built for serious traders
Amounts are sealed before any public record exists. They only become visible once both parties are locked in. You cannot front-run a number you cannot see.
Trade details are encrypted and stored on the blockchain. Share a view key with your compliance team or regulator and they can read everything: amounts, firm names, timestamps.
USDC and EURC settle directly on Arc Testnet. Finality in under a second. Gas is paid in USDC so there are no ETH swings eating into your spread.
Both sides settle together. If anything does not add up, the whole thing reverts. You get exactly what you agreed to, or nothing moves.
Post a quote for anyone to take, or send it directly to a specific wallet address. The size stays private until settlement either way.
Every trade is recorded on Arc permanently: the sealed amounts, the settlement, the timestamps. Share the view key with an auditor whenever you need and they can read everything.
