Satoshi a BTC Stablecoin: A Decentralized Stablecoin Protocol Based on Bitcoin

What is Satoshi a BTC Stablecoin

Imagine you have a very precious gold bar (just like Bitcoin), which is highly valuable, but not very convenient for buying coffee or daily expenses, because it's too large and every transaction requires cutting off a small piece, which is cumbersome to calculate. Now, Satoshi a BTC Stablecoin (TSAT for short) is like slicing this big gold bar into countless small gold coins according to the smallest unit—“satoshi” (the smallest unit of Bitcoin, 1 Bitcoin equals 100 million satoshis)—and these small coins can circulate on a very fast and cheap payment system (the Solana blockchain).

Simply put, TSAT is a “Bitcoin-backed stablecoin”, but instead of being pegged to the US dollar like USDT, it is “pegged to the smallest unit of Bitcoin”. Each TSAT token represents one satoshi and is fully collateralized by tBTC reserves from the “Threshold Network”, ensuring it maintains a 1:1 value relationship with Bitcoin.

Its core target users are those who want to “simply hold and use the smallest unit of Bitcoin”. You no longer need to deal with a long string of decimals after the Bitcoin point, but can directly use integer TSATs for measurement and transactions, making “saving Bitcoin” more intuitive and motivating.

Project Vision and Value Proposition

The vision of the TSAT project is to make “satoshi the default accounting unit of global finance”, helping ordinary people resist inflation and truly accumulate Bitcoin wealth.

The core problems it aims to solve are:

• Complexity of Bitcoin decimals: For ordinary users, numbers like 0.00000001 BTC are hard to understand and perceive. TSAT makes Bitcoin savings and transactions more intuitive by displaying balances as integers.
• Bitcoin usability in DeFi: Although Bitcoin is the gold standard for value storage, it is not always convenient to use directly in decentralized finance (DeFi) applications. By issuing TSAT on Solana, it combines Bitcoin’s value storage properties with Solana’s high-speed, low-cost transaction capabilities, allowing even the smallest unit of Bitcoin to participate in the DeFi ecosystem.

The key difference from similar projects is that most stablecoins are pegged to fiat currencies (such as the US dollar), while TSAT is directly pegged to Bitcoin’s smallest unit, “satoshi”. This means it retains Bitcoin’s scarcity and anti-inflation characteristics, while providing the usability of a stablecoin.

Technical Features

The technical features of TSAT are mainly reflected in the following aspects:

• Based on Solana blockchain: TSAT is deployed on the Solana blockchain, which means it benefits from Solana’s “fast transaction speed” and “extremely low transaction fees”.
• Bitcoin collateral: Each TSAT is fully collateralized by tBTC reserves from the “Threshold Network”. tBTC is a wrapped Bitcoin that brings Bitcoin into other blockchain ecosystems, ensuring TSAT is pegged to real Bitcoin value.
• Fixed supply: The total supply of TSAT is set at 21 trillion, corresponding to the total number of satoshis in Bitcoin (21 million Bitcoins x 100 million satoshis/Bitcoin = 2.1 trillion satoshis). This means TSAT’s supply is fixed and scarce.
• Smart contract distribution: The 21 trillion TSAT tokens are minted at project launch and stored in a “fixed ratio smart contract”. TSAT is only distributed into circulation when the corresponding Bitcoin collateral enters via tBTC, ensuring transparency and solvency.

Tokenomics

TSAT’s tokenomics are designed to directly reflect Bitcoin’s characteristics:

• Token symbol: TSAT
• Issuing chain: Solana
• Total supply and issuance mechanism: TSAT’s maximum supply is 21 trillion, equal to the total number of satoshis in all Bitcoin. All tokens are minted at project launch and stored in a smart contract. Only when Bitcoin is deposited as collateral (via tBTC) are the corresponding TSAT released into circulation.
• Inflation/Burn: Due to its fixed supply and collateral mechanism, TSAT itself does not have inflationary properties. No burn mechanism is explicitly mentioned in current materials.
• Current and future circulation: As of October 7, 2025, the self-reported circulating supply on CoinMarketCap is about 80,195,953 TSAT. However, the CoinMarketCap team notes this data has not been verified.
• Token utility: The main use of TSAT is as the “smallest unit of Bitcoin” for trading, saving, and participating in DeFi activities within the Solana ecosystem. It allows users to hold and use Bitcoin value in a more intuitive way.
• Token allocation and unlock information: No detailed token allocation or unlock plan was found in search results.

Team, Governance, and Funding

Regarding TSAT’s “core team members, team characteristics, governance mechanism, treasury and funding operations”, there is currently no clear whitepaper or official documentation providing detailed explanations in public search results.

However, some supplementary materials (such as YouTube videos) mention the name “DavinciJ15”, who appears to be a promoter or related figure for the project, and reference the website “satoshi15.com”. But this does not constitute an official disclosure of the project’s core team and governance structure.

A healthy blockchain project typically discloses its core team members, their backgrounds, the project’s governance model (e.g., centralized decision-making or decentralized autonomous organization DAO via token holder voting), and the sources and uses of project funds. Lack of such information may increase project opacity.

Roadmap

Based on currently available information, TSAT’s future plans include:

• Cross-chain expansion: The project plans to expand TSAT to other blockchain ecosystems beyond Solana, meaning you may be able to use TSAT on more blockchains in the future.
• Migration to dedicated SATChain: The ultimate plan is to migrate to a “dedicated SATChain” built on a “Bitcoin-linked DAG network” (Directed Acyclic Graph, a data structure more flexible than traditional blockchains). This vision aims to combine Bitcoin’s security with the scalability and programmability of modern blockchains.

No specific timeline of major historical milestones and events for the project was found.

Common Risk Reminders

Investing in any cryptocurrency carries risks, and TSAT is no exception. Here are some common risk reminders:

• Technical and security risks:
  • Smart contract vulnerabilities: TSAT’s collateral and distribution rely on smart contracts. If there are vulnerabilities, it could lead to loss of funds or system attacks.
  • tBTC collateral risk: TSAT’s value depends on tBTC’s collateralization of real Bitcoin. If the tBTC system has issues, such as insufficient collateral or attacks, TSAT’s value stability will be affected.
  • Solana network risk: As part of the Solana ecosystem, TSAT may also be affected by Solana’s own performance, stability, or security issues.
• Economic risks:
  • De-pegging risk: Although TSAT aims for a 1:1 peg to satoshi, in extreme market conditions or due to collateral management issues, “peg deviation” may occur, causing its value to diverge from satoshi.
  • Liquidity risk: If market demand for TSAT trading is insufficient, it may result in low liquidity, making it hard to buy or sell quickly, or causing large bid-ask spreads.
  • Market volatility: Although it is a stablecoin, its underlying asset Bitcoin is highly volatile, which may indirectly affect market confidence in TSAT.
• Compliance and operational risks:
  • Regulatory uncertainty: The global cryptocurrency regulatory environment is still evolving, and future policy changes may impact stablecoin projects.
  • Project transparency: Currently, information on the team, governance, and detailed fund usage is relatively limited, which may increase operational risk.

Project Summary

Satoshi a BTC Stablecoin (TSAT) is an innovative stablecoin project running on the Solana blockchain. It is not pegged to fiat currency, but “pegged 1:1 to the smallest unit of Bitcoin—satoshi”. Its core value lies in ensuring a peg to Bitcoin through tBTC reserves from the “Threshold Network”, and leveraging Solana’s high speed and low cost to make the smallest unit of Bitcoin more conveniently circulate and be used in the DeFi ecosystem.

The project aims to solve the usability barrier caused by Bitcoin’s decimal complexity, allowing ordinary users to more intuitively understand and accumulate Bitcoin wealth, and hopes to promote satoshi as the accounting unit of global finance. Its fixed total supply of 21 trillion echoes Bitcoin’s scarcity, and smart contracts ensure transparent collateral distribution.

However, currently, public information on the project’s core team, detailed governance structure, and fund operations is relatively limited, which increases the project’s opacity to some extent. Although the project has planned cross-chain expansion and future migration to a dedicated SATChain, these are still in early stages.

Overall, TSAT offers a novel Bitcoin stablecoin model, which is attractive to users who want to conveniently use Bitcoin value in the Solana ecosystem while avoiding the impact of Bitcoin’s price volatility. But like all cryptocurrency projects, it comes with technical, economic, and compliance risks. Before considering participation, it is strongly recommended that you conduct in-depth research and fully understand all potential risks. This is not investment advice.
