Telegram has over one billion users. Ethereum has the deepest and most mature decentralized finance ecosystem in crypto. For years these two worlds have remained largely separate, connected only through clunky bridges and wrapped assets.
TAC Protocol was built to close that gap directly. Rather than asking Ethereum developers to rebuild their applications in TON's native programming language, TAC created a full EVM-compatible Layer 1 blockchain that lets developers deploy their existing Solidity smart contracts unchanged, while giving Telegram and TON users native access to those applications through Telegram Mini Apps.
The technical achievement is genuine. Mainnet launched with a Halborn security audit finding no critical issues, a validator set including Chorus One, Animoca, and other reputable infrastructure operators, and pre-committed liquidity from blue-chip DeFi protocols on day one.
For Muslim investors, the question is whether this infrastructure achievement translates into a permissible investment. We ran TAC through the full CoinStudy Halal Crypto Standard (HCS) methodology. Here is the complete picture.
TAC passes the CoinStudy HCS Sharia red-line screening with no direct violations. It scores 71 out of 100 and is classified as Halal With Concerns. The core EVM bridging infrastructure is genuinely neutral and permissible, consistent with how CoinStudy treats Ethereum and other general-purpose smart contract platforms. The concerns that bring the score down are tokenomics concentration, extreme price volatility driven by speculative cross-chain flows, and the presence of conventional lending protocols among its day-one ecosystem partners.
TAC is an EVM-compatible Layer 1 blockchain built on Cosmos SDK technology, purpose-built to connect Ethereum's decentralized application ecosystem with The Open Network and Telegram's user base.
The architecture consists of three main components. The TAC EVM Layer is a complete Layer 1 blockchain achieving approximately two-second finality through delegated Proof of Stake, fully compatible with standard Ethereum development tools including Hardhat, Truffle, Foundry, MetaMask, and Web3.js. The TON Adapter is a distributed network of sequencers that handles secure cross-chain messaging between TON and the TAC EVM layer using a Byzantine Fault Tolerant framework. Proxy Apps are smart contracts deployed on both TON and TAC EVM that handle the translation between the two ecosystems, allowing what TAC calls Hybrid dApps, applications that combine Ethereum-compatible smart contract logic with Telegram-native distribution.
TAC additionally integrates with Babylon's Bitcoin staking protocol, allowing Bitcoin holders to stake BTC in a self-custodial manner to add additional economic security to the TAC network through a dual-layer security model.
The TAC token serves as the gas token for transactions on the TAC EVM layer, the staking asset securing the network through delegated Proof of Stake validators, and the governance token for protocol decisions. TAC has raised $11.5 million from investors including Hack VC, TON Ventures, Animoca Brands, Symbolic Capital, and Ankr.
This is the most important section of this analysis given the methodology precision CoinStudy has refined through recent community challenges.
TAC's core protocol function is bridging EVM smart contract execution to TON and Telegram users. This is structurally identical to what CoinStudy considers genuinely neutral infrastructure. The protocol does not generate interest income. It does not operate a lending or borrowing product at the chain level. It does not promote gambling or prediction markets as a flagship use case in its own published materials.
Some research notes mention Euler Finance, a lending protocol, as a day-1 partner application on TAC. Under CoinStudy's methodology, established and confirmed through the Unicity Network and Raiku community challenges, the correct compliance test is whether the TOKEN'S OWN MECHANISM generates prohibited income, not whether third-party developers choose to deploy lending or other applications on neutral infrastructure.
Euler Finance choosing to deploy on TAC is precisely analogous to Aave or Compound deploying on Ethereum. This is a third-party developer's choice using neutral infrastructure, not a feature of TAC's own protocol design. This is why TAC passes Layer 1 screening rather than triggering an Ecosystem Riba Exposure red line in the way that AINFT or BTT did, where the project's OWN documentation explicitly promoted lending integration as a core token financial utility feature.
This distinction matters and CoinStudy applies it consistently. TAC's own promotional materials describe its mission as connecting Ethereum DeFi broadly to Telegram users, without singling out lending or any other specific financial product as the flagship promoted use case the way Fermah promotes prediction markets or AINFT promotes JustLend integration.
This is the primary driver of TAC's reduced score and it deserves honest and direct treatment.
TAC's price has shown extreme volatility, including a 137% single-day surge and 182% gain over a seven-day period according to recent market data, alongside daily trading volume increases of over 1,900% in short windows. Independent research analysis explicitly characterizes this price action as "structurally fragile, built on cross-chain flows and low liquidity rather than sustainable demand."
This level of speculative price volatility, disconnected from organic protocol usage growth, raises a genuine Maysir consideration. While TAC's underlying infrastructure purpose is legitimate, the market's current engagement with the token appears substantially driven by speculative momentum trading rather than conviction in the bridging infrastructure's long-term utility.
Additionally, of the 10 billion total token supply, only 4.7 billion are currently circulating, with a fully diluted valuation of approximately $549 million against a circulating market capitalization of approximately $255 million. This significant supply overhang, combined with the project's framework that rewards early supporters and builders ahead of full decentralization, creates meaningful Tokenomics Fairness concerns about future dilution and insider distribution patterns that independent research notes have not been fully verified for multisig controls and unlock schedules.
TAC's architecture, while professionally audited by Halborn, Trail of Bits, and Quantstamp, introduces what independent research describes as "extra trust assumptions and sequencing complexity" inherent to any cross-chain bridging design. A post-mortem analysis of a security incident affecting the TAC Bridge has been publicly documented by the project itself.
Bridge security incidents are a recurring pattern across the cross-chain infrastructure category broadly, and this is reflected as a genuine Gharar consideration in the scoring rather than a Layer 1 violation, since the underlying activity remains permissible bridging infrastructure with documented but managed technical risk.
TAC's bridging and EVM execution infrastructure does not generate interest income directly. The presence of lending protocols among third-party applications deployed on the chain follows the same infrastructure neutrality principle that applies to Ethereum hosting Aave, or Solana hosting Kamino. The Financial Exposure Risk score of 18 out of 25 reflects this genuinely neutral core architecture, with deductions reflecting the broader DeFi ecosystem TAC is explicitly built to bootstrap, which will inevitably include both permissible and impermissible applications as it matures.
TAC's cross-chain architecture, while professionally audited, introduces inherent bridging complexity and has documented a security incident requiring post-mortem analysis. The Gharar score of 10 out of 15 reflects this genuine technical uncertainty alongside the broader early-stage nature of connecting two historically separate developer ecosystems.
TAC's core purpose, connecting developer ecosystems and enabling application access, is a genuine and productive infrastructure goal. However the documented extreme volatility and independent research characterization of recent price action as built on "cross-chain flows and low liquidity rather than sustainable demand" reflects significant current speculative activity disconnected from organic usage. The Maysir score of 9 out of 15 reflects this honest tension between genuine infrastructure purpose and current speculative market reality.
Ecosystem Riba Exposure — ✅ Passed. TAC's core EVM bridging protocol does not generate interest income. Third-party lending applications choosing to deploy on TAC's neutral infrastructure follow the same principle applied to Ethereum and other general-purpose smart contract platforms.
Gambling and Betting — ✅ Passed. No gambling mechanism exists at the protocol level and TAC's own promotional materials do not feature gambling-adjacent applications as a flagship use case.
Haram Industry — ✅ Passed.
Guaranteed Interest — ✅ Passed. Staking rewards come from genuine delegated Proof of Stake network security participation.
Synthetic Interest Products — ✅ Passed. TAC is a gas, staking, and governance token.
No red line violations were found. TAC is fully eligible for HCS scoring.
TAC is scored across 7 Shariah principles with a total of 100 points.
On Financial Exposure Risk, weighted at 25%, TAC scores 18 out of 25. Genuinely neutral bridging infrastructure with no direct interest-generating mechanism. Deductions reflect that TAC's explicit mission is bootstrapping a broad DeFi ecosystem that will inevitably include lending and other haram-adjacent applications as third-party deployments.
On Gharar and Uncertainty, weighted at 15%, TAC scores 10 out of 15. Professional security audits from Halborn, Trail of Bits, and Quantstamp provide meaningful assurance. Deductions reflect documented bridge security incident history, inherent cross-chain trust assumptions, and early-stage ecosystem uncertainty.
On Maysir and Speculation, weighted at 15%, TAC scores 9 out of 15. Genuine infrastructure purpose at the protocol level. Significant deductions reflect documented extreme price volatility independently characterized as speculative cross-chain flow activity rather than organic usage-driven demand.
On Underlying Business Activity, weighted at 15%, TAC scores 14 out of 15. Bridging developer ecosystems and enabling application access across blockchain networks is a genuinely permissible and valuable infrastructure activity.
On Utility and Real Use, weighted at 10%, TAC scores 8 out of 10. Mainnet is live with reputable validators, pre-committed blue-chip liquidity, and genuine developer tooling compatibility. Deduction reflects that durable organic usage beyond initial bootstrapped liquidity remains unproven per independent research assessment.
On Tokenomics Fairness, weighted at 10%, TAC scores 6 out of 10. Only 47% of total supply is currently circulating with significant future unlock pressure. The framework explicitly rewards early supporters and builders ahead of full decentralization, raising fairness considerations for later participants.
On Transparency and Governance, weighted at 10%, TAC scores 6 out of 10. Independent research notes that governance and admin-key details, multisig controls, and foundation treasury movement disclosures remain incompletely verified, representing a meaningful transparency gap for a project at this market capitalization.
Overall HCS Score: 71 out of 100 — Halal With Concerns
Before investing in TAC Protocol, ask yourself honestly.
Do I understand that TAC's core infrastructure is genuinely neutral, similar to Ethereum, and that third-party lending applications deploying on it are a separate compliance question from the TAC token itself? Am I aware of the documented extreme price volatility and independent research characterizing recent price action as speculative rather than usage-driven? Do I understand that only 47% of total supply is currently circulating with significant future unlock pressure ahead? Have I considered the bridge security risk inherent to TAC's cross-chain architecture, including its documented security incident history? Would I be comfortable explaining TAC's tokenomics and governance transparency gaps to a qualified Islamic scholar?
TAC Protocol (TAC) is classified as Halal With Concerns under the CoinStudy Halal Crypto Standard with a score of 71 out of 100.
It passes all Sharia red-line checks. The core EVM bridging infrastructure connecting Ethereum's developer ecosystem to TON and Telegram's billion-plus user base is genuinely neutral and serves a real productive purpose, consistent with how CoinStudy evaluates other general-purpose smart contract infrastructure.
The concerns are real and honestly reflected in the score. Documented extreme price volatility characterized by independent research as speculative rather than usage-driven, significant token supply overhang with only 47% currently circulating, and incomplete transparency around governance and treasury controls all warrant genuine caution from Muslim investors.
For Muslim investors who hold conviction in TAC's bridging infrastructure thesis specifically, with full awareness of the tokenomics concentration and current speculative market dynamics, the underlying protocol concept does not raise the same direct compliance concerns as platforms that explicitly promote haram-classified applications as flagship features.
