SPL20 : A New Innovation Powering Solana NFTs and More

Cover Image for SPL20 : A New Innovation Powering Solana NFTs and More

In the ever-evolving landscape of cryptocurrencies, SPL20 "Solana Inscriptions" emerges as a unique cryptocurrency protocol backed by a vibrant community and centered around Solana.

What is SPL20?

SPL20 inscriptions are unique Solana addresses that contain images stored directly on the blockchain. This differs from regular NFTs that store their art on a third-party service like Arweave. Now, your images have their own address instead of an HTML link Storing art on-chain ensures the art's integrity and longevity, free from any external data storage limitations

These images, however, do not have to be immutable. For example, mutability allows for new use cases such as native trait swapping or day/night cycles for gaming NFTs

This concept draws inspiration from BRC-20, Bitcoin's experimental standard for creating fungible tokens (hence the name SPL-20)

Inscriptions are ranked by how early they are, similar to Bitcoin Ordinals. This is done to introduce FOMO and get people inscribing on-chain

A user must hold update authority to inscribe an SPL20. This means they are the NFT's creator, ensuring project owners control the inscription process

This also prevents holders from inscribing a different image from their own when they don't hold the update authority

Background and Features

SPL20 inscriptions are influencing the future of digital art on Solana. They offer a vision where digital art is secure, permanent, and fully integrated within the network While SPL20 inscriptions innovate digital art on Solana, they bring several challenges The introduction of the SLP-20 inscriptions has far-reaching implications for the Solana blockchain:

Scalability and Efficiency: Solana is renowned for its high throughput and low transaction costs. The adoption of SLP-20 inscriptions further enhances the scalability and efficiency of the network.

Developer-Friendly Environment: SLP-20 inscriptions simplify the development process for tokens on Solana, making it more accessible to a broader audience of developers. The standardized format reduces the complexity of token creation.

Enhanced Interoperability: The interoperability enabled by SLP-20 inscriptions promotes collaboration and interaction between different projects within the Solana ecosystem. This interconnectedness creates a more vibrant and dynamic blockchain environment.

Global Accessibility: The tokenization of assets and the expansion of DeFi protocols on Solana contribute to the platform’s global accessibility. Users from around the world can participate in decentralized finance, trade tokenized assets. And engage in NFT transactions, fostering a more inclusive financial ecosystem.

Concerns and Criticisms

Storing large files directly on Solana can lead to several issues. Critics are concerned that inscriptions will lead to a bloated state, increasing bandwidth requirements for validators and costs for infrastructure providers

Critics also note Solana doesn't really need SPL20s for NFT functionality. Bitcoin's limited scripting capabilities make BRC20s essential for implementing NFTs, whereas Solana can handle complex NFT transactions and storage natively without needing an additional layer


The standardization of tokens not only streamlines the development process but also expands the scope of potential use cases, ranging from DeFi protocols to NFT marketplaces and beyond.
