# Interoperability and Compatibility

## **Which wallets can be used for transactions?**

The **Toto Chain supports** the following wallets:

* **MetaMask** (for Ethereum-compatible transactions)
* **Talisman** (for multi-chain interoperability)
* **Polkadot.js** (for Substrate-based interactions)

However, **signature type changes may impact the usability of Polkadot.js** at present​.

***

## **How does the Toto Chain interact with other blockchains or parachains in the Polkadot ecosystem?**

* The **Toto Chain is built on Substrate** but is **not part of the Polkadot network**.
* It **combines Substrate and Ethereum components**, making it **compatible with Ethereum-based tools while maintaining Substrate's flexibility**.
* While **cross-chain messaging (XCM) is possible**, it has **not been implemented yet**​.

***

## **Can the Toto Chain support cross-chain transactions?**

* **Yes, cross-chain transactions (XCM) are technically possible**, but they **haven’t been implemented yet**.
* Since the chain **supports Ethereum-based wallets and tools**, **bridging with Ethereum and EVM-compatible chains could be feasible** in the future​.

***

## **What tools or APIs are available for developers to build on the Toto Chain?**

The Toto Chain offers:

* **Ethereum-compatible tools** (allowing developers to use familiar Ethereum dev stacks).
* **REST APIs** for interacting with the chain.
* **Monitoring and analytics tools**:
  * **Grafana**
  * **Prometheus**
  * **Substrate Telemetry**
* **Block time differences**: Toto has a **3-second block time**, which is significantly faster than Ethereum​.
