Blockchains & Gas Fees
Altura supports nine blockchains: Ethereum, Binance Smart Chain (BSC), Polygon, Arbitrum, Optimism, Fantom, Cronos, Polygon zkEVM and Avalanche. Each blockchain has unique features and benefits, so it's important to consider which blockchain is best suited for your game or project.
Altura also supports four testnets: Binance Smart Chain Testnet, Polygon Mumbai Testnet, Goerli Ethereum Testnet and Sepolia Ethereum Testnet.
When minting NFTs or a collection on the Altura marketplace, you can specify the blockchain via the dropdown menu in the navigation bar. It's important to note that once an NFT is minted on a specific blockchain, it is bound to that chain and cannot be transferred to a different one. When using Altura's API or SDKs, you don't need to specify the blockchain your NFTs reside on, as Altura will automatically detect this.

Gas fees are the fees paid to miners to process transactions on a blockchain. Gas fees are paid in the native currency of the blockchain, such as Ether for Ethereum or BNB for Binance Smart Chain. Gas fees are a crucial component of any blockchain transaction and are necessary to ensure that transactions are processed in a timely manner.
Additionally, if you're just starting out and want to test your game or application on a blockchain without incurring real gas fees, you can use a faucet to obtain gas on our testnet chains. This will allow you to interact with the blockchain and test your application without spending real funds.
