Supported Tokens

• Standard NFTs: An NFT on Solana is a unique, indivisible digital asset with metadata stored on-chain or off-chain, representing ownership of items like art, collectibles, or gaming assets. Each NFT has a unique identifier, ensuring its distinctness and rarity.
• Compressed NFTs: A compressed NFT on Solana is a lightweight, cost-efficient version of a regular NFT. It leverages Merkle trees to reduce storage costs by keeping the bulk of the data off-chain while maintaining the asset's integrity and verifiability on-chain.
• Fungible Tokens: Fungible Tokens on Solana are interchangeable digital assets with a consistent value, such as SPL tokens. They are commonly used for payments, rewards, and liquidity within decentralized finance (DeFi) ecosystems.
• MPL Core Assets: MPL Core Assets are Solana NFTs built on the next-generation Metaplex Core standard. They feature a single-account design optimized for NFTs, enabling advanced functionality such as enforced royalties, collection-level operations, and plugin-based customization.
• Token 2022 Assets: Token 2022 Assets on Solana are an upgraded standard for fungible and non-fungible tokens, offering enhanced functionality and efficiency compared to the SPL token standard. They include advanced features like native support for royalties, multisig authority, and extended metadata capabilities, making them ideal for next-generation decentralized applications and financial use cases.
