One account, every chain

Unbridge.

A quorum of bonded operators threshold-signs a native transaction for any chain, coordinated and slashed by a Solana program. No bridge, no wrapped asset, no honeypot to drain.

Post your first signing intent in under two minutes.

Signed and broadcast — the group key was never assembled

A Solana account signed a native Bitcoin transaction. It confirmed.

The premise

Every bridge is a contract holding custody, and the largest one is always the target. Unbridge holds nothing. A quorum of operators signs natively for the destination chain, the group secret is never reconstructed, and the only thing you trust is a program you can read and a signature you can verify.

Bridge
vs signature.

A bridge parks your asset in a contract and hands you a claim on it. Unbridge leaves the asset where it is and signs for it directly on the chain that needs it.

What moves
Asset locked, minted, redeemed across chains
Nothing moves; a native signature is produced
What the destination sees
A wrapped IOU and a bridge contract
An ordinary signature on its own curve
Trust surface
Bridge validators holding custody
Bonded operators, slashed on-chain
Failure mode
A drained bridge, stranded wrapped assets
A request that simply expires

Five chains.
One key.

Each destination receives a signature on its own curve, from the same Solana account. Two schemes, branched per VM family. Nothing is wrapped.

Questions.

A control plane for cross-chain signing on Solana. Instead of bridging an asset, a quorum of bonded operators threshold-signs a native transaction for the destination chain. One Solana account, a real signature on every chain, no bridge in the path.

Get started

Sign on
any chain.

Connect a wallet and post a signing intent. A bonded operator set threshold-signs a native transaction on the chain you choose. No bridge, no wrapped asset, no custodian holding your funds.
