All other tokens, whether fungible or non-fungible (NFTs), are defined as SPL tokens. SOL SPL Token-2022 are used to create digital assets on the Solana blockchain, just like ERC-20 tokens on Ethereum. Defined by the Solana Program Library, SPL tokens support both fungible and non-fungible assets. Ethereum Solana’s ecosystem provides a foundation for SPL token development, supported by significant metrics: https://x.com/arorautkarshini/status/1955988104004653429?embedable=true https://x.com/arorautkarshini/status/1955988104004653429?embedable=true Types of SPL Tokens The Solana Program Library (SPL) supports a variety of token standards, defined by the Token Metadata program, to accommodate these diverse use cases. The Token Metadata program tracks a token’s fungibility using the Token Standard enum on the Metadata account. Fungible Simple SPL Tokens Supply >= 0 Limited metadata (name, symbol, description, image) Decimal points: ≥1 (e.g., 6 for USDC) Eg: USDC Fungible Asset Semi-fungible tokens Supply >= 0 Extended metadata, attribute-heavy Decimal points: 0 (no divisibility beyond whole units) Eg: Gaming items like a sword NonFungible Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets) Eg: Mad Lads ProgrammableNonFungible Controlled Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets with rules) Eg: NFT with enforced royalties Fungible Simple SPL Tokens Supply >= 0 Limited metadata (name, symbol, description, image) Decimal points: ≥1 (e.g., 6 for USDC) Eg: USDC Fungible Simple SPL Tokens Supply >= 0 Limited metadata (name, symbol, description, image) Decimal points: ≥1 (e.g., 6 for USDC) Eg: USDC Simple SPL Tokens Simple SPL Tokens Supply >= 0 Supply >= 0 Limited metadata (name, symbol, description, image) Limited metadata (name, symbol, description, image) Decimal points: ≥1 (e.g., 6 for USDC) Decimal points: ≥1 (e.g., 6 for USDC) Eg: USDC Eg: USDC Fungible Asset Semi-fungible tokens Supply >= 0 Extended metadata, attribute-heavy Decimal points: 0 (no divisibility beyond whole units) Eg: Gaming items like a sword Fungible Asset Semi-fungible tokens Supply >= 0 Extended metadata, attribute-heavy Decimal points: 0 (no divisibility beyond whole units) Eg: Gaming items like a sword Semi-fungible tokens Supply >= 0 Extended metadata, attribute-heavy Decimal points: 0 (no divisibility beyond whole units) Eg: Gaming items like a sword NonFungible Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets) Eg: Mad Lads NonFungible Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets) Eg: Mad Lads Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets) Eg: Mad Lads Mad Lads ProgrammableNonFungible Controlled Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets with rules) Eg: NFT with enforced royalties ProgrammableNonFungible Controlled Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets with rules) Eg: NFT with enforced royalties Controlled Unique SPL Tokens Supply = 1 Decimal points: 0 (indivisible, unique assets with rules) Eg: NFT with enforced royalties ***🔍︎ ***USDC operates on Solana’s Token Program. Using the explorer, you can analyze token metrics like total supply, addresses of mint and freeze authorities, decimal precision, associated token accounts, and a log of recent transactions. SPL Token Standard: USDC is a fungible token, meaning it is interchangeable and divisible, unlike non-fungible tokens (NFTs) that are unique and indivisible. 1:1 USD Peg: USDC is a stablecoin issued by Circle, fully backed by cash and cash-equivalent reserves, ensuring each token is redeemable for one US dollar.

Considerations Security: Never expose private keys in production code. Use environment variables (.env) and add them to .gitignore. Cost: Devnet SOL is free via airdrops, but mainnet deployments require real SOL for gas fees. IPFS: Ensure your IPFS provider (e.g., Filebase) supports pinning for persistent data availability. Testing: Test thoroughly on Devnet before Mainnet deployment to avoid costly errors. Security: Never expose private keys in production code.

Testing Summary This guide delivers a comprehensive walkthrough for creating and deploying an SPL token on the Solana blockchain using the Metaplex Token Standard and Umi client. The process includes setting up a development environment with Node.js and TypeScript, generating a wallet with airdropped SOL on Devnet, uploading metadata to IPFS via Filebase, and minting a fungible token with provided code examples. SPL tokens, built on Solana’s high-throughput infrastructure, support diverse use cases such as fungible assets and NFTs, offering a scalable and cost-efficient foundation for Web3 projects.
