🚀 Core objectives
Upgrade the existing Qraffle Smart Contract on $Qubic to the latest reviewed implementation. - Add verifiable on-chain randomness and refine asset-raffle features. - Build on the previously approved asset-raffle release, not an initial deployment.
⚙️ Technical implementation
Integrate the RANDOM smart contract to purchase independent entropy (collateral tier 0, 256 bits) at each ENDEPOCH for winner selection. - Entropy purchase is additive and fail-safe: if RANDOM's pool is empty or purchase fails, settlement proceeds with the digest-only seed and the fee is fully refunded. - Remove restrictions blocking QRAFFLE SC shares and QXMR token from being used as asset-bundle raffle prizes. - Lower default QuRaffle pool/entry amount from 10,000,000 Qu to 1,000,000 Qu. - Add tests for RANDOM integration, including successful purchase, graceful fallback, and unfunded reserve scenarios.
💡 Innovative approach
Mix independent entropy from RANDOM with the existing digest-based seed, strengthening randomness without blocking settlement. - Build a self-sustaining entropy reserve retained in the contract's own balance, never transferred out.
💰 Economic aspects
Fund the entropy reserve with a 1% carve-out from QuRaffle and Asset Raffle Qu pools; token-denominated pools do not fund it. - Adjust winner/creator share of Qu-denominated pools from 80% to 79% to accommodate the reserve (remaining 21%: 5% burn, 5% DAO/register, 8% shareholders, 1% charity, 1% fee, 1% entropy reserve).
🌍 Expected impacts
Enhanced fairness and verifiability in raffle winner selection. - Expanded asset-raffle prize options by including previously restricted tokens. - Lower entry barrier for QuRaffle pools, increasing accessibility and participation.

What Smart Contract Risk Means for STON.fi Users
When people talk about risk in decentralized finance, the conversation often begins with price volatility, wallet safety, or phishing scams. But for STON.fi users, one of the most important and often least understood risks is smart contract risk.
Smart contract risk is the possibility that the on-chain code behind a swap, liquidity action, or related process contains a weakness, behaves unexpectedly, or interacts in an unintended way with another contract. In simple terms, it is code and execution risk. It is not the same as losing access to your wallet, and it is not the same as market movement. It is the risk that the contract itself, or the way it communicates with other contracts, may fail, be exploited, or produce an outcome different from what the user expected.
That distinction matters because STON.fi is a non custodial platform. It does not hold your private keys or take control of your funds in the way a centralized service might. You remain in control of your wallet and you approve every action yourself. However, even in a self-custodial environment, your assets still depend on the correct execution of signed transactions. A wallet that stays in your hands does not remove the possibility that a smart contract can behave incorrectly once a transaction is sent.
What Smart Contract Risk Really Means
For STON.fi users, smart contract risk is best understood as the risk that the logic governing a transaction may not perform exactly as intended. A swap might fail because of contract conditions, a token might behave in a non-standard way, or a contract interaction might expose a vulnerability that was not obvious from the outside.
This is why smart contract risk should not be confused with other common risks. A sudden token price drop is a market risk. Clicking a fake website is a phishing risk. Sending funds to the wrong address is a user error. Smart contract risk is different: it comes from the behavior of the deployed code itself.
Even though the platform is non-custodial, a self-custodial DEX can still expose assets during the execution of a transaction. Once you sign, you are relying on the contract system to carry out the operation correctly. That is why understanding how the swap flow works is so important.
How a STON.fi Swap Moves Through Contracts
A STON.fi swap is not just a single click. It is a series of contract interactions that must happen in the right order.
First, the user reviews the quote and authorizes a Jetton transfer with the DEX payload. That signature is the user’s approval for the transaction to begin.
Next, the Router receives the notification and forwards it to the correct Pool. The Router’s job is to route the action to the proper destination based on the swap path and transaction details.
Then the Pool applies the swap logic and checks the minimum output amount. This is one of the most important protection steps because it helps ensure that the user does not receive less than expected.
Finally, the contracts deliver the result or trigger refund and failure handling. If something does not go as planned, the contract system should either complete the operation safely or return the funds through the designed failure path.
This structure is one reason STON.fi users should pay close attention to transaction details before signing. The smart contract system is doing the heavy lifting, and each step depends on the correctness of the one before it.
Why Smart Contract Risk Still Exists
A common misunderstanding in DeFi is that an audit or a security review removes risk entirely. It does not.
No review can guarantee that a contract will never contain a flaw or that a future interaction will never create a problem. A contract can be secure at the time it is reviewed and still later face new risks from protocol changes, unexpected token behavior, ecosystem interactions, or newly discovered vulnerabilities.
That is why smart contract risk remains relevant even for platforms that are well built, transparent, and actively monitored. The question is not whether risk exists. The real question is how much the protocol has done to reduce it and how carefully the user manages it.
How STON.fi Reduces the Risk
STON.fi has taken several concrete steps to reduce smart contract risk and increase user confidence.
One important measure is the independent Trail of Bits security review of the DEX v2 contracts in January 2025. An external review by a respected security firm helps validate the contract architecture and identify weaknesses before they become user-facing problems.
STON.fi also maintains public technical documentation covering the Router, Pool, Vault, and related components. That transparency matters because users and developers can better understand how the system works instead of relying only on assumptions or marketing claims.
In addition, STON.fi supports an active HackenProof bug bounty and CertiK monitoring. Bug bounties encourage ethical security researchers to report issues responsibly, while continuous monitoring helps provide an additional layer of oversight after deployment.
Another important protection is the use of immutable Pool contracts and time-locked Router upgrades. Immutable contracts reduce the chance of hidden changes to core pool behavior, while time-locked upgrades make changes to routing logic more visible and less abrupt. Together, these features help create a more predictable environment for users.
What This Means for Everyday Users
For ordinary users, the main lesson is simple: security reviews and safeguards improve confidence, but they do not eliminate all risk.
If you are making a large swap, providing liquidity, or interacting with a token that behaves unusually, it is worth slowing down and checking the essentials. Confirm that you are using the official STON.fi interface. Review the transaction details carefully. Pay attention to the minimum output amount, since that is the protection against receiving less than expected. Consider whether the token itself has unusual mechanics or external dependencies. And always size your position carefully instead of committing more than you are comfortable risking.
This kind of caution is especially important in DeFi because the user is not protected by a traditional intermediary. There is no customer support desk that can reverse a contract execution after the fact. Once the transaction is signed and finalized, the contract logic determines the outcome.
The Bigger Picture
Smart contract risk is one of the defining realities of decentralized finance. It is not a reason to avoid DeFi altogether, but it is a reason to approach it with awareness.
STON.fi’s design, documentation, security review history, bug bounty efforts, and contract architecture all work together to reduce that risk. Still, no system can promise complete immunity from bugs, edge cases, or external token issues. That is why informed users remain the strongest line of defense.
A careful user checks the interface, reviews the output conditions, and signs only when the transaction details match the intended action. In DeFi, discipline is part of security.
So before every larger STON.fi swap, ask yourself one simple question: Have I checked the official interface and the minimum output setting before signing?
That single habit can make a meaningful difference.
Final Thought
Smart contract risk is not about fear. It is about understanding how on-chain systems work and recognizing where the responsibility sits in a non-custodial environment. For STON.fi users, that means combining protocol-level trust with personal caution.
The best approach is not to assume risk is absent, but to understand where it lives, how it is reduced, and how to manage it wisely every time you interact with the contracts.

Ethereum (ETH) is more than just a cryptocurrency—it is the world's leading smart contract platform, powering thousands of decentralized applications (dApps), DeFi protocols, NFTs, tokenized real-world assets (RWAs), and blockchain infrastructure.
Since transitioning to Proof-of-Stake (The Merge), Ethereum has significantly reduced its energy consumption while enabling ETH holders to earn staking rewards and helping secure the network.
Why Ethereum Could Achieve Much More
🚀 Institutional Adoption: Spot Ethereum ETFs have accelerated institutional exposure, making ETH increasingly accessible to traditional investors.
🏦 Tokenization Boom: Major financial institutions are exploring Ethereum for tokenizing stocks, bonds, and real-world assets, a market many analysts believe could reach trillions of dollars over the coming decade.
🌍 Largest Developer Ecosystem: Ethereum continues to have the most active blockchain developer community, driving continuous innovation and long-term network growth.
🔥 Deflationary Supply: Since the implementation of EIP-1559, a portion of transaction fees is permanently burned. During periods of high network activity, ETH issuance can become net deflationary.
⚡ Layer-2 Expansion: Scaling solutions such as Arbitrum, Optimism, Base, and zkSync are increasing transaction throughput while reducing costs, strengthening Ethereum's ecosystem.
Long-Term Outlook
Many market participants view Ethereum as the backbone of Web3 and decentralized finance. If institutional adoption, tokenization, and blockchain-based financial infrastructure continue to expand, Ethereum could play an even larger role in the global digital economy.
However, Ethereum also faces challenges, including competition from high-performance blockchains such as Solana and Sui, regulatory uncertainty in some jurisdictions, and the need to continue improving scalability and user experience.
Ethereum is not simply a digital asset—it is a programmable financial and computing platform that could become one of the core infrastructures of the next generation of the internet.
