What is ERC-1155?

On June 17 2019 ERC-1155 Multi Token Standard became an official Ethereum token standard. Where the maybe more well known ERC-20 and ERC-721 tokens require the deployment of separate contracts per token type, the core concept behind ERC-1155 is that a single smart contract may include any combination of fungible tokens, non-fungible tokens or other configurations.

A good comparison is that of a vending machine: insert a coin and press a button, and there is the potential to receive a variety of different drinks or snacks that it contains. For Synergy of Serra, this means pressing a button to open your crate, and then you have the potential to receive a variety of six cards out of all the different possible cards, all in a single contract.

How do you treat the NFTs' metadata?

All cards are blockchain assets, meaning their ownership is recorded on the blockchain. However, please keep in mind that the metadata (including art) is not saved on the blockchain.

This is because good game design may require balancing changes, so cards are always subject to change. This is especially true in the Alpha Phase, where there will be balance changes more frequently.

Will the items upon purchase already be ERC1155 tokens, or will they need to be minted afterwards?

All Synergy of Serra Items - crates, cards, keys, etc - are directly minted on the blockchain and belong to their holder alone.

How do you handle high network fees?

There are no network fees on Serra.

The team specifically built on the Polygon blockchain so that users wouldn't have to negotiate network fees. In fact, users don't even need to know about blockchain at all. Synergy of Serra doesn't require a wallet, plugins, cryptocurrencies, or any blockchain technology knowledge.

However, in case you want to learn about this groundbreaking technology, feel free to visit our Discord community and ask.

Can I add my own MetaMask or Nano Ledger public key to my SoS account?

Yes, you are able to prove ownership of any public key by signing a message. For this process, you don't have to add the private key itself.
