xDAI Stake Bridge Review 2026: Gnosis Chain's Canonical Bridge

xDAI Stake Bridge is the canonical bridge between Ethereum and Gnosis Chain. DefiLlama files it under Canonical Bridge on Ethereum and describes it as the first USD stable blockchain and a multi-chain staking token. It lists the STAKE token and two audits.

The bridge holds about $255.5 million in TVL, up about 1.0% over the last seven days. That puts it among bridges with real money behind them, though TVL alone says nothing about safety.

The official site belongs to Gnosis, which describes itself as working on payments (Gnosis Pay), infrastructure (Gnosis Chain and the Ethereum Economic Zone) and peer-to-peer money (Circles). Gnosis also points to earlier work such as the Conditional Token Framework and the incubation of Safe and CoW Protocol. The bridge is the entry point for moving assets into that ecosystem. Beyond that, public sources say little about the bridge itself.

A canonical bridge links two blockchains. Tokens are usually locked or held on one chain, and a matching balance is made available on the other. To return, the balance on the second chain is removed and the original asset is released.

Here the two ends are Ethereum and Gnosis Chain. Gnosis Chain is the network the homepage describes as having the security and configurability of an L2 with the diversity and depth of Ethereum. DefiLlama also ties the project to STAKE, a multi-chain staking token.

The project does not give contract design, validator set or any limits. Treat the above as the general model for canonical bridges and check the official documentation for how this one is operated.

Bridge fees are not published publicly reviewed. No transfer fee, minimum, limit or timing is stated by DefiLlama or its homepage.

Expect to pay Ethereum gas for the transaction on the Ethereum side, as with any on-chain transfer. The bridge interface linked from the Gnosis site is where any other charges and estimated times should appear before you confirm.

DefiLlama lists two audits for the project, but the project does not name the auditors or give their findings. No incidents are mentioned publicly, and nothing here shows the project is shut down. The homepage carries a 2026 copyright line and recent news items, which suggest the organisation is active.

Bridges are a common target for exploits because they hold locked funds. Risk comes from smart contracts, validator or operator keys, and the security of the destination chain. Using a canonical bridge does not remove those risks.

Bridge only what you can afford to have tied up, use the official interface, and double-check network and token details on every transfer. Regulatory status for the bridge itself is not stated publicly.

This bridge is for Ethereum users who want to hold or use assets on Gnosis Chain, and for holders of the STAKE token who need to move it between chains. It is less relevant if you only use Ethereum or other networks.
