Building NFTs on Solana with Token Extensions
A developer documents learning how to create and manage NFTs directly at the token level on Solana using Token Extensions. The author built an NFT on Solana Devnet, configured a mint with supply=1 and zero decimals, attached on-chain metadata via the Metadata Extension, created a collection with the Group Extension, and linked the NFT to that collection using the Member Extension. The write-up emphasizes inspecting on-chain accounts and extension data (rather than relying solely on SDKs or Metaplex tooling) and explores ideas for more dynamic, updateable on-chain assets such as evolving achievement NFTs, on-chain certificates, and membership tokens.
Practical developer-level explanation of Solana token primitives and Token Extensions that can influence how programmable digital assets and on-chain collections are architected; useful technical insight but not industry-shifting on its own.

Key Takeaways & Evidence Grounding
- Author created an NFT on Solana Devnet using Token Extensions.
- An NFT on Solana is modeled as a token mint with supply one, zero decimals, and metadata.
- The build used Metadata, Group, and Member Extensions to add metadata and collection relationships at the token level.
- The author minted a single token, audited account structure and extension data on-chain, and updated metadata after creation.
- The article demonstrates inspecting on-chain accounts with tools such as the spl-token initialize-metadata command.

Solana Token-2022 Enables Programmable Non-Transferable Tokens
A developer experiment demonstrates how Solana's Token-2022 standard embeds token rules at the protocol level, enabling programmable behavior such as non-transferability, protocol-enforced transfers, and on-chain burning. The author created a Token-2022 mint with the Non-Transferable extension, instantiated token accounts (including an ATA for a second wallet), attempted a restricted transfer which was blocked by the protocol-level rule, and burned tokens to observe deterministic supply changes. The post highlights Token-2022's shift from application-level enforcement to protocol-level state machines and outlines next steps like transfer-fee extensions, metadata binding, and token-gated applications.
Solana Enforces Token Transfer Fees at Protocol Layer
The author demonstrates how Solana’s Token-2022 extensions let developers bake transfer fees into a token’s mint account so the network enforces fees on every transfer, eliminating application-layer bypass risks common in Web2 payment flows. Using the TransferFeeConfig, transfers require an expected-fee value or the transaction fails; withheld fees are held in token accounts until a mint withdraw authority collects them. The piece gives CLI examples, notes real-world uses (meme token BERN’s automatic burns/rewards and Paxos’ Permanent Delegate clawback on USDP), and highlights composability by stacking fee and interest-bearing extensions on the same mint. The author frames protocol-level enforcement as enabling trustless treasuries and royalty streams that survive failures of Web2 backends.
Deep Dive: How Solana Transactions Work
A Dev.to post by Vinay (published 2026-05-10) describes hands-on experiments to understand Solana transaction mechanics. The author inspected transactions via Solana Explorer and CLI, built a reusable transfer tool, and intentionally forced failures to study execution logs, fees, and confirmation lifecycle. The article outlines transaction components (signatures, instructions, account keys, recent blockhashes, fee payer info, execution logs), describes Solana's commitment levels (Processed, Confirmed, Finalized), and highlights that failed transactions still consume validator compute and incur fees. The post reframes Solana transactions as atomic state transitions in a distributed system rather than simple request/response API calls.
