Bitcoin STAMPS (also called SRC-20 tokens) are a new class of Bitcoin-native NFTs that store tiny images directly in spendable transaction outputs on the Bitcoin blockchain. Because the image data is encoded as base64 and split across transaction outputs, STAMPS are designed to be immutable and resistant to pruning, distinguishing them from other inscription methods that rely on witnesses or external databases. Technical constraints limit STAMPS to very small graphics (24×24 pixels) and only a few file types (PNG, GIF, SVG), which reduces storage overhead but also constrains creative possibilities. The protocol is still early-stage: initial implementations used Counterparty broadcasts, while updated SRC-20 encoding writes directly to Bitcoin transactions, and ecosystem integration with wallets and marketplaces is ongoing. Reception is mixed—some criticize the network cost and limited utility, while others view STAMPS as a way to spur Bitcoin infrastructure and collector interest.

The SRC-20 token standard is a fungible token specification emerging within the Stacks and Bitcoin ecosystem that enables developers to issue, transfer, and manage tokenized assets anchored to Bitcoin through the Stacks network.

SRC-20 tokens are a token standard built on top of Bitcoin using the Bitcoin Stamps protocol to embed JSON-like data into unspent transaction outputs (UTXOs). This standard enables the creation of fungible tokens that operate in parallel with Bitcoin, with transaction fees paid in BTC. SRC-20 emphasizes immutable, non-prunable data storage by writing information directly to UTXOs, in contrast to BRC-20 which stores data in witness/ordinal structures. Because SRC-20 allows flexible data sizes, creators can attach larger payloads but may incur higher transaction costs. Adoption is currently limited compared with BRC-20, and wallet and protocol support for SRC-20 remains in early stages. As a result, SRC-20 offers a distinct trade-off between permanence and cost, suited to projects that prioritize on-chain immutability on Bitcoin.

SRC-20 tokens are a Bitcoin-based token standard that enables embedding data directly into Bitcoin transactions using the Bitcoin Stamps protocol. They allow creators to mint fungible (and in some workflows non-fungible) digital assets by storing image and metadata in UTXOs in Base64 format, which makes the data immutable and non-prunable. SRC-20 tokens support common image formats such as JPG, PNG, GIF and SVG, but practical implementations impose a strict image size limitation (commonly 24x24 pixels) to keep on-chain storage feasible. The standard has seen rapid adoption with hundreds of thousands of tokens minted and a market capitalization that has grown into the tens of millions. SRC-20 expands Bitcoin’s utility beyond simple payments, offering secure collectible, NFT and token use cases while integrating transaction fees and minting activity into the existing Bitcoin economy.

SRC-20 is a token standard tied to Bitcoin Stamps that enables minting and transferring tokens by embedding immutable data directly into Bitcoin transactions. Originating as an evolution of earlier concepts like colored coins, Ordinals and BRC-20, SRC-20 (driven by the Stamps protocol) emphasizes permanent on-chain storage using UTXOs and Counterparty-style encoding to resist pruning and censorship. The standard differs from BRC-20 by prioritizing immutability of inscription data and using a distinct workflow for encoding and broadcasting token metadata. The article explains how Stamps store data (OP_RETURN and multi-sig for larger files), how to mint and acquire SRC-20 tokens via tools like stampsrc.github.io, stampchain.io/src20 and the Hiro Wallet, and outlines ecosystem trade-offs and potential community tensions over expanding Bitcoin’s use cases.

SRC-20 (Bitcoin Stamps) is a token standard introduced in March 2023 that enables the creation of immutable, image-based tokens on the Bitcoin network by embedding base64-encoded image data into the UTXO set via the Counterparty protocol. Designed by Mike In Space and built on the Secure Tradeable Art Maintained Securely (STAMPS) concept, SRC-20 seeks to address perceived weaknesses of earlier ordinal-based standards like BRC-20 by prioritizing permanence and UTXO-based indexing. SRC-20 stamps typically store small PNG/GIF/WebP/JPG files (commonly suggested as 24x24, 8-color PNG/GIF) encoded in the transaction’s description field, and are mintable via tools such as Stamp Wallet and tradable on marketplaces like OpenStamp. While gaining rapid adoption (examples include tokens like PEPE, STAMP, and KEVIN), SRC-20 tokens remain experimental, volatile, and require careful handling of wallet compatibility and on-chain costs.

SRC-20 is a token standard that leverages Bitcoin Stamps technology to inscribe data onto Bitcoin UTXOs, enabling the creation and transfer of fungible tokens that operate alongside Bitcoin’s native coin. Unlike BRC-20, which stores data in the witness portion of transactions via Ordinals, SRC-20 stores information directly on UTXOs through Stamps, offering immutable and non-prunable data storage. This approach allows creators to attach arbitrary-sized payloads to transactions, though larger data sizes increase transaction fees payable in BTC. While SRC-20 enhances Bitcoin’s utility by enabling fungible asset issuance, it is relatively new and has seen more limited adoption compared to BRC-20, with fewer wallets and exchange integrations at present.

This KuCoin Learn article explains SRC-20 tokens and Bitcoin Stamps as a new approach to creating fungible digital assets on the Bitcoin blockchain. SRC-20 tokens leverage the Bitcoin Stamps protocol to embed immutable metadata into UTXOs, making token parameters and associated data permanent and resistant to pruning. The guide compares SRC-20 with existing alternatives like BRC-20 and Bitcoin Ordinals, outlines potential use cases such as digital collectibles, DeFi tokenization, and community tokens, and highlights practical steps for minting and interacting with SRC-20 tokens via platforms and compatible wallets. It also discusses advantages—security, permanence, and expanded utility—and challenges including costs, scalability, and limited integration.

Bitcoin Stamps, often referred to as SRC-20 tokens, are a novel form of digital collectible recorded directly on the Bitcoin blockchain. Unlike some other token standards that place data in witness fields, SRC-20 uses spendable transaction outputs (UTXOs) to embed small image data and metadata, giving these tokens enhanced permanence and resistance to pruning. Creation of a Stamp follows strict rules — images must be JPG/GIF/PNG/SVG and limited to 24×24 pixels, each Stamp needs a unique numerical identifier, and encoded data is uploaded to a centralized repository such as stampchain.io with transactions flagged via a "stamp:base64" descriptor. SRC-20 tokens benefit from Bitcoin’s security and immutability but face trade-offs including higher transaction fees, limited scalability, nascent tooling, and regulatory uncertainty. Examples of notable SRC-20 tokens include PEPE SRC, KEVIN, STAMP, and SATO, illustrating the format’s growing creative and cultural uptake within the Bitcoin ecosystem.
