⛓ Gnosis Chain

The Gnosis Chain is a stable payments EVM (Ethereum Virtual Machine) blockchain designed for fast and inexpensive transactions. The chain uses a unique dual-token model; xDai is a stable token used for transactions, payments, and fees, and Proof of Stake protection will be provided by GNO with the consensus-layer Gnosis Beacon Chain.

The Gnosis/xDai ecosystem continues to flourish with many new project migrations, integrations, applications, and a mature toolset for developers. Explore the depth of the ecosystem in the Project & DApps section, or visit to see and interact with active projects.

My Safe transaction failed - what went wrong?

Case 1: The "outer" transaction failed

The most likely case is, that not enough gas was provided. This is an example transaction where this happened. It should not happen when you use your Safe via one of our official interfaces.

The less likely case is, that invalid Signatures have been provided.

This is an example transaction for this case. This should also not happen via our interfaces.

Case 2: The "inner" transaction failed

"Reverted"

One case is, that the inner transaction reverted.

This is an example transaction for this case. It generally means that there was an error in the contract that was called from the Safe. Hence we recommend getting in touch with the 3rd party/dapp that you are using to debug this.

"Out of gas"

Now another case is that the inner transaction ran out of gas. Safe transactions has an "inner" gas limit called safeTxGas.

Transfer xDai to DAI from the xDai chain to the Ethereum Mainnet

1. Send xDai coins to the Token Bridge address 0x7301CFA0e1756B71869E93d4e4Dca5c7d0eb0AA6 on the xDai Сhain using any wallet software.
2. Wait for the transaction confirmation on the xDai chain (5 seconds).
3. Copy the transaction hash of the confirmation and connect to the Ethereum mainnet.
4. Visit the helper contract:
5. In the getMessageHash method field add the following information from your originating transaction and press the Query button. The method will return a hashed message.
6. Copy the message hash and paste into the getMessage method. If you receive 0x0 it means either the bridge oracles did not send a confirmation for the withdrawal yet or the data entered in the step 3 is incorrect. Double check the info and if it is correct you will eventually receive the message.
7. Once you receive the message, use the message hash again this time with the getSignatures method. It will return a blob with packed signatures provided by the validator. The method could fail if not enough signatures are collected.

Gas prices

However, multiple major blockchains have had issues with high gas fees on these transactions. Fees are continuing to rise and are turning many away from the use of stablecoins. This is where Gnosis steps in with its stablecoin, xDAI. This token is designed to be a stablecoin with low fees, fast transactions and high security. xDAI serves two main purposes: currency for gas fees and stable payments. Transaction fees are covered with xDAI, which also aids in keeping transaction fees low. It is used as a stable form of payment, as it is always worth $1.
