Somnia Bridge will bring assets from other chains onto Somnia. Validators observe each transfer and attest to it as part of Somnia consensus, with no separate relayer network or multisig in the middle.

Five steps, one receipt.
A transfer is a short chain of events on two networks. Each step is checked, and the last one leaves a balance your contracts can use straight away.
- 01
Send
Assets go to the bridge contract on the source chain.
- 02
Observe
Somnia Agents read the source-chain event from independent data sources.
- 03
Attest
Validators on the Somnia Validator Network agree it happened and sign a receipt.
- 04
Release
Assets are minted or released on Somnia, final in under a second.
- 05
Use
The balance is live onchain, and contracts can act on it in the same block.
Built into the chain, not bolted on.
The bridge uses parts of Somnia that already exist: Agents to read other chains, the Validator Network to agree, and Reactivity so contracts can respond to a deposit.
- AttestedFinal0 sSub-second on Somnia1 s
Sub-second release
Once validators attest, release on Somnia inherits the chain’s deterministic finality.
- Deposit arrivesSame blockYour contractVenueVault
Reactive deposits
Contracts can act on an arriving transfer in the same block, so a deposit can go straight to where it is needed.
- Typical bridgeRelayerMultisigSomnia bridgeValidator network
No relayer or multisig in the middle
Transfers are checked by the validators that run Somnia, instead of a small external committee.
- Agent feeTBCSomnia gasTBCTotalShown before you signIllustrative
Fees shown before you sign
You pay an agent fee for attestation and Somnia gas. Amounts are TBC and always shown before you confirm.
Checked by the validators that run the chain.
A bridge is only as safe as whoever signs off on a transfer. On Somnia that is the same Validator Network that agrees every block.
- 01
Agent attestation
Source-chain transfers are read by Somnia Agents, not a separate relayer network.
- 02
Validator agreement
The Somnia Validator Network agrees each transfer before funds are released.
- 03
Signed receipts
Every transfer carries a receipt showing what was observed and who attested to it.

Bridge questions, answered.
- When will Somnia Bridge launch?
It is coming soon. Join the waitlist and we will tell you when it opens.
- Which chains and assets will it support?
The first list will be published before launch. Until then, both are TBC.
- How is a transfer secured?
Somnia Agents observe the transfer, the Somnia Validator Network agrees it happened, and a signed receipt is recorded on Somnia.
- How long does a transfer take?
Release on Somnia is final in under a second once attested. Time on the source chain varies; estimates TBC.
- What will it cost?
An agent fee for attestation plus Somnia gas. Amounts are TBC and shown before you sign.
- Can my contract react to a deposit?
Yes. With Reactivity, a contract can act on an arriving transfer in the same block.
