UMBRA
Privacy-first cross-chain bridge
Swap XMR, BTC, ETH, TON, SOL and more — trustless MPC threshold signatures, real-time rates, zero KYC.
What is Umbra?
Umbra is a non-custodial cross-chain bridge built around Monero — the only cryptocurrency with mandatory privacy. It enables trustless swaps between privacy coins and public blockchains using FROST threshold signatures (2-of-3 MPC), meaning no single party ever holds your funds.
What makes Umbra different from every other bridge is the Proof Layer: the bridge does not ask to be trusted — it produces cryptographic evidence for everything it does, and ships the tools to check that evidence offline.
The Proof Layer
Bridges are the most-hacked primitive in crypto (Ronin $624M, Multichain $126M, Nomad $190M, Harmony $100M — drained over minutes-to-hours while nothing watched). Umbra's answer is a layer of verifiable accountability that no major bridge ships today:
