Overview of Chains Supported by Coinbase NFT Marketplace

Coinbase's NFT marketplace is designed to offer a user-friendly and secure platform for buying, selling, and creating non-fungible tokens. Currently, the platform primarily supports the Ethereum blockchain, which is widely recognized for its robust smart contract capabilities and extensive NFT ecosystem. This means that most NFTs listed or minted on Coinbase NFT are built using the ERC-721 or ERC-1155 token standards.

In addition to Ethereum, Coinbase has also expanded support to include Polygon (MATIC), a Layer 2 scaling solution known for offering low-cost transactions and faster processing times. This expansion allows creators and collectors to interact with NFTs at reduced gas fees while maintaining compatibility with the broader Ethereum ecosystem. It’s important to note that although Ethereum and Polygon are the main chains supported, Coinbase may introduce additional blockchains in the future based on market demand and technological advancements.

How to Mint NFTs on Coinbase NFT

To create an NFT on Coinbase NFT, users must first connect their Coinbase Wallet or use a compatible Web3 wallet such as MetaMask. Once connected, they can navigate to the "Create" section of the platform. Here, they will be prompted to upload the digital file they wish to tokenize — whether it's an image, video, audio file, or 3D model.

After uploading the media, users need to provide metadata including the name, description, and attributes of the NFT. One crucial step during this process is selecting the blockchain on which the NFT will be minted — currently limited to Ethereum and Polygon. Choosing Polygon typically results in lower transaction costs, making it ideal for creators aiming to minimize expenses.

Following this, users must confirm the minting transaction through their wallet. Gas fees will vary depending on the selected chain and current network congestion. Upon successful confirmation, the NFT will appear in the creator's collection and can then be listed for sale.

Setting Up Creator Royalties on Coinbase NFT

A key feature for creators using the Coinbase NFT platform is the ability to earn royalties from secondary sales of their work. To enable this functionality, creators must set up royalty percentages before minting their NFT. During the creation process, there is an option to input the percentage of future sales that the creator would like to receive each time the NFT changes hands.

The royalty percentage can range from 0% to 10%, and it is applied automatically whenever the NFT is resold on a supported marketplace. Importantly, these royalties are enforced via smart contracts, ensuring that creators continue to benefit from the appreciation of their digital assets.

It should be emphasized that royalty settings cannot be changed after the NFT is minted, so creators should carefully consider the percentage they choose before finalizing the minting process. Additionally, not all marketplaces respect creator royalties, but Coinbase NFT ensures enforcement within its own ecosystem.

Supported File Types and Metadata Standards

Coinbase NFT accepts a wide variety of digital file types for NFT creation. These include common formats such as PNG, JPEG, GIF, MP4, MP3, GLB (for 3D models), and more. The platform also allows creators to embed metadata directly into their NFTs, providing richer context and enhancing discoverability.

Metadata fields include customizable options such as name, description, properties, levels, and stats. These fields help categorize NFTs and improve how they are displayed on the platform. Creators can also define specific traits and rarities, which can influence buyer interest and overall value perception.

When minting, creators have the ability to generate multiple editions of the same asset or issue a one-of-a-kind piece. Each edition can carry unique identifiers or variations, allowing for dynamic collections and series-based projects.

Fees and Transaction Costs on Coinbase NFT

Understanding the fee structure is essential for both buyers and sellers on Coinbase NFT. When minting an NFT, users are charged network transaction fees (commonly referred to as gas fees), which depend on the selected blockchain and current network activity.

For Ethereum, these fees can fluctuate significantly, especially during periods of high demand. In contrast, Polygon offers consistently lower fees, making it a popular choice for cost-conscious creators. Coinbase does not charge any upfront listing fees, but it does collect a service fee upon the successful sale of an NFT.

The standard service fee is 2.99% of the sale price, excluding any applicable creator royalties. Buyers may also incur small transaction fees when purchasing NFTs, depending on the payment method used (e.g., credit card vs. crypto transfer).

FAQ: Frequently Asked Questions

Q: Can I transfer my NFTs from Coinbase NFT to other platforms?

Yes, once you mint or purchase an NFT on Coinbase NFT, it resides in your wallet and can be transferred to other compatible wallets or marketplaces. However, if you set up creator royalties, those will only apply on platforms that enforce them.

Q: Is there a minimum royalty percentage I can set?

No, you can choose to set your royalty percentage anywhere between 0% and 10%. Setting it to 0% means you won’t receive any income from future resales unless the buyer decides to gift you a portion separately.

Q: How do I check if my NFT is earning royalties?

You can view royalty earnings by checking your wallet address on supported marketplaces or by reviewing transaction history within your Coinbase Wallet. Earnings are typically received automatically in the form of ETH or MATIC, depending on the blockchain used.

Q: Are there plans for Coinbase NFT to support Solana or other chains?

As of now, official support is limited to Ethereum and Polygon, but Coinbase has indicated openness to expanding chain support in response to user demand. No official announcements have been made regarding Solana or other networks.
