Second-order NFTs purchased on OSB Launch Pad can be sold on other marketplaces.
The royalties for secondary sales are as follows.
Royalty
In marketplaces that implement EIP-2981, royalties can be earned based on the royalties set for NFTs.
*Example: OpenSea、Rarible、Mintable…etc
In marketplaces that do not implement EIP-2981, the marketplace’s own settings will be the standard, so the royalties set when releasing the NFT on Launchpad will be discarded.
■What is EIP-2981?
Since some current marketplaces have their own royalty payment implementations, there were cases where secondary distribution royalties could not be received if the marketplace was different.
EIP-2981 applies to NFTs published in ERC-721 and ERC-1155 standards. As long as it is between platforms that support EIP-2981, even across platforms, NFT creators or rights owners can receive secondary distribution royalties every time they are sold or resold.
■What is EIP?
The Ethereum Improvement Proposal (EIP) is a standard that defines proposed new features and processes for Ethereum. The EIP contains proposed technical specification changes and serves as the community’s “source of truth”. Standards for Ethereum network upgrades and applications will be developed through discussions in the EIP process.
Anyone within the Ethereum community can create his EIP. Guidelines for writing an EIP are included in his EIP 1. The EIP should provide a concise technical specification of the functionality and rationale. EIP authors build consensus within the community and document objections. The technical standards for submitting a qualified EIP are high and most EIP authors are application developers or protocol developers.
*ERC-721 is the NFT standard. By having a uint256 variable called tokenId , in ERC-721 contracts, the contract address and uint256 tokenId are paired, and the token standard can have uniqueness.
*ERC-1155 is a standard token standard for contracts that manage multiple token types, with the same functions as ERC-20 and ERC-721 tokens, or even both at the same time.
