Depending on which environment your application is connecting, your blockchain transactions will be directed to a specific blockchain network. Please find below an overview of the different endpoints and the associated blockchain networks.

The sandbox environment is your playground. It connects to testnet-blockchains, meaning that no real cryptocurrency and NFTs are involved. You can use testnet-faucets to receive cryptocurrency or to generate NFTs using Smart contract API.
Note: Wallets created on sandbox cannot be linked with production so treat them as test - wallets
The Ethereum Virtual Machine or EVM is like a powerful, decentralized computer that helps people do things on the Ethereum network, and its actions are recorded on the blockchain for everyone to see and agree upon. EVM is a platform for smart contract deployment and execution.
The Ethereum Virtual Machine serves as a software platform enabling developers to build decentralized applications (dApps) on the Ethereum network. All Ethereum accounts and smart contracts exist on this virtual machine.
EVM compatible blockchains refers to the blockchains on which you can write and deploy smart contracts that are compatible with the Ethereum Virtual Machine.
Compatibility with the EVM enables numerous blockchains such as Polygon, Avalanche, and Binance Smart Chain to reduce the entry barrier for developers. This is possible because their native codes align with Ethereum, allowing seamless deployment of smart contracts on these new chains.
Hence, EVM chains can offer solutions to facilitate interoperability among blockchain networks and dApps adhering to Ethereum principles.
