# Fantom Safe

[Fantom Safe](https://safe.fantom.network/welcome) is an open-source smart contract wallet operating on the Opera chain, designed for multi-signature management of crypto assets and interactions with other smart contracts, making it ideal for team fund management.

You can designate owners of the safe and specify the minimum number of approvals required for a transaction to be executed. This differs from a single-key wallet, also known as an externally owned account (EOA), where one person holds the private key and approves transactions independently.

Fantom Safe supports FTM and tokens on the Opera chain, allowing you to transfer them to the safe as usual. You can view the fiat values of your assets on your dashboard and conveniently send funds from it.

## Getting Started

As [Fantom Safe](https://safe.fantom.network/welcome) is based on Gnosis Safe, you can use most tutorials based on them. For selecting the Opera mainnet or test net, use the menu in the top-right corner.

## Transaction Service API

We offer an [API to keep track of transactions](https://safe-txservice.fantom.network/) sent via Fantom Safe smart contracts.

## Troubleshooting

Due to the caching mechanism, transaction nonces can become unsynchronized. If a transaction cannot be created from your Safe, verify that the current nonce for your Safe transaction matches the nonce displayed in the Safe UI.

To resolve this, open the settings menu of your Fantom Safe to view the current nonce. Copy this nonce into your Safe transaction, and the issue should be resolved.
