Why did the price of SUI go up?

Sui (SUI) increased by 2.39% in the last 24 hours, slightly outperforming the overall crypto market’s 2.2% gain. This continues a strong weekly trend with a 12% rise, driven by:

  1. Launch of native stablecoins – USDi and suiUSDe introduced in partnership with BlackRock and Ethena.
  2. Technical breakout – Price surpassed the $3.53 resistance level, indicating positive momentum.
  3. Growing institutional interest – Coinbase futures listing and talks of an ETF.

Key point to watch: Can SUI stay above $3.50 to counteract the bearish MACD signals?


What could affect the price of SUI?

Sui’s price depends on the growth of decentralized finance (DeFi), government regulations, and competition from other blockchain technologies.

  1. Stablecoin buybacks – New native stablecoins could increase demand for SUI by using revenue to buy back tokens.
  2. ETF speculation – The SEC’s review of SUI exchange-traded funds (ETFs) might bring more institutional investors.
  3. Solana rivalry – Upgrades to Solana’s network could challenge Sui’s speed advantage.

Deep Dive

1. Stablecoin Adoption & Buybacks (Positive Outlook)

Overview: Sui plans to launch two native stablecoins in late 2025: suiUSDe (a synthetic dollar) and USDi (backed by BlackRock’s BUIDL). These stablecoins aim to increase liquidity in DeFi applications on Sui’s network. Revenue generated from these stablecoins will be used to buy back SUI tokens, reducing the total supply and potentially increasing value (Cryptotimes).

What this means: Buying back tokens can make SUI scarcer, which may push prices up. More stablecoin use can also lead to more transactions on the network. However, regulators could slow down or limit these stablecoins if audits of their reserves don’t meet standards under the GENIUS Act.

2. ETF Prospects & Regulatory Risk (Mixed Outlook)

Overview: The U.S. Securities and Exchange Commission (SEC) is reviewing two proposals for SUI ETFs from 21Shares and Canary Capital. If approved, these ETFs could attract large institutional investors. In July 2025, futures trading for SUI reached $1.2 billion, showing strong market interest (Yahoo Finance).

What this means: Approval of SUI ETFs could lead to price rallies similar to what happened with Bitcoin ETFs. On the other hand, delays or rejections might cause investors to sell, as seen with other altcoin ETFs in 2024.

3. Layer-1 Speed Wars (Potential Challenge)

Overview: Solana’s recent Alpenglow upgrade has reduced transaction finality times to 100–150 milliseconds, faster than Sui’s roughly 400 milliseconds. While Sui’s parallel processing is still better for complex transactions, Solana’s speed improvements could attract developers away from Sui (CoinMarketCap).

What this means: If Solana closes the speed gap, Sui’s advantage in high-volume DeFi and gaming applications might weaken. However, Sui’s current $1 billion total value locked (TVL) in DeFi could help maintain its position if the ecosystem keeps growing.

Conclusion

Sui’s outlook for 2025 includes strong positive factors like stablecoin-driven buybacks and ETF interest, balanced against risks from regulatory hurdles and competition. Breaking above $4.57 per token looks possible if stablecoin adoption grows quickly, but dropping below $3.03 might lead to bigger price declines. The key question remains: Will SUI’s DeFi TVL double before Solana’s next upgrade?


What are people saying about SUI?

The Sui (SUI) community is divided between optimistic investors aiming for $7 and cautious traders watching the $3.40 support level. Here’s what’s currently shaping the conversation:

  1. $7 price targets driven by excitement around ETFs and growth in Bitcoin finance (BTCFi)
  2. Concerns about a $77 million token unlock that could impact supply
  3. A key technical battle at $4.20 resistance that could determine the next price move
  4. Strong ecosystem growth with user numbers up 145%

In-Depth Look

1. ETF Buzz Could Push SUI to $7

John Morgan (@johnmorganFL) highlights that if SUI breaks through the $4.20 resistance level, it could reach $7. This optimism is fueled by potential inflows from institutional products like the 21Shares ETF and growing adoption of Bitcoin finance (BTCFi).
See original post
What this means: If approved, ETFs could bring over $300 million in new capital to SUI, which would be a strong positive. However, ETF approval is not guaranteed.

2. $77 Million Token Unlock Raises Concerns

The Sui community (@SuiCommunity) points out that 77 million SUI tokens, worth about $275 million, are scheduled to unlock soon. This represents 2.1% of the circulating supply and could put downward pressure on the price, especially around the $3.40 support level.
See original post
What this means: While large token unlocks can lead to selling pressure, past unlocks have had little effect on SUI’s price. Still, traders should watch this closely.

3. Technical Battle at $4.20 Resistance

Analyst @RektCapital notes that SUI is at a critical point near $4.20. A daily close above this level could spark a 40% rally, pushing the price to about $5.36. However, the Relative Strength Index (RSI) is at 72, indicating the asset might be overbought.
See original post
What this means: There’s potential for a strong price move if SUI breaks $4.20, but investors should be cautious of a possible pullback due to overbought conditions.

4. Developer Growth Signals Long-Term Strength

Electric Capital (@ElectricCapital) reports that Sui leads Layer 1 blockchains with 54% developer growth over two years and ranks in the top 5 for full-time blockchain developers. With 209 million accounts and over $2 billion in total value locked (TVL), the ecosystem shows healthy organic growth.
See original post
What this means: This strong developer activity and user growth are positive signs for SUI’s long-term potential, although concerns about token dilution remain.

Conclusion

Opinions on SUI are mixed. The ecosystem’s rapid growth is encouraging, but upcoming token unlocks could cause volatility. Technically, breaking above $4.20 could open the door to gains above $5, while the $3.40 to $3.70 range remains an important support zone. Keep an eye on the NASDAQ ETF decision expected around January 15, 2026, and the upcoming SuiFest event in Singapore on October 2, 2025, for potential market-moving news. With 145% user growth, SUI appears to be just getting started.


What is the latest news about SUI?

Sui is expanding its ecosystem with new stablecoins, improved security, and enhanced trading options. Here’s a quick look at the latest developments:

  1. Stablecoin Launch (October 2, 2025) – SUI Group introduced two stablecoins: USDi, backed by BlackRock, and suiUSDe, which generates yield to support DeFi liquidity.
  2. New Hardware Wallet (October 2, 2025) – Citadel Wallet released Suiball, a hardware wallet designed to improve security for Sui’s Bitcoin-focused ecosystem.
  3. Margin Trading Increase (October 2, 2025) – Kraken now offers 10x leverage on SUI trading, showing growing interest from institutional traders.

In-Depth Look

1. Stablecoin Launch (October 2, 2025)

What happened:
SUI Group teamed up with Ethena Labs and BlackRock to launch two stablecoins:

Why it matters:
This strategy combines traditional finance (TradFi) reliability with decentralized finance (DeFi) innovation. USDi may attract cautious institutional investors, while suiUSDe’s buyback feature could create ongoing demand for SUI tokens. However, U.S. regulators are closely watching synthetic stablecoins under the GENIUS Act, which could affect compliance. (Cryptotimes)

2. New Hardware Wallet (October 2, 2025)

What happened:
Citadel Wallet launched Suiball, the first hardware wallet built specifically for the Sui blockchain. It features “clear signing,” which means users can see exactly what they’re approving before confirming transactions. It supports Sui-native assets, including BTCfi tokens, and works with DeFi platforms like Suilend.

Why it matters:
Since about 30% of Sui’s total value locked (TVL) is in Bitcoin-related assets, Suiball addresses security concerns for users holding large amounts of BTCfi tokens. This could encourage more institutional investors to join the Sui ecosystem, although it competes with established multi-chain wallets like Ledger. (Crypto.News)

3. Margin Trading Increase (October 2, 2025)

What happened:
Kraken increased the margin trading leverage for SUI from 2x to 10x, putting it alongside other major coins like ADA and LINK. The open interest in SUI futures reached $1.61 billion, showing strong trader activity.

Why it matters:
Higher leverage means traders can borrow more to increase their positions, which boosts liquidity but also raises the risk of forced sell-offs if prices move sharply. This change comes as SUI’s price rose 11.47% over the past week. Traders should watch funding rates (currently averaging +0.0054%) to avoid overheating the market. (Coinspeaker)

Conclusion

Sui is strengthening its decentralized finance infrastructure with new stablecoins, improving security with Suiball, and deepening market liquidity through higher leverage. These moves position Sui as a growing center for Bitcoin-related finance. While technical signals suggest a potential price rally toward $5, regulatory scrutiny of synthetic stablecoins and leveraged trading could challenge this momentum. BlackRock’s role in USDi might even open doors for a future Sui-based ETF.


What is expected in the development of SUI?

Sui’s 2025 roadmap focuses on expanding its technology, improving security, and growing its user base. Key upcoming highlights include:

  5. SuiFest Singapore (October 2, 2025) – A major event to showcase new projects and partnerships.

In-Depth Look

1. SuiPlay 0X 1 Gaming Launch (2025)

What it is: Sui is developing a handheld gaming device along with the PLAYTR0N operating system. This platform plans to support over 70 games and work with 65 game studios (Bitget). The goal is to make Web3 gaming more accessible to everyday users.
Why it matters: This could boost the number of users and transactions on the Sui network, which is positive for SUI’s growth. However, delays in hardware production or partnerships could slow progress.

2. Mysticeti V2/FastPath Upgrade (2025)

What it is: An upgrade to Sui’s core technology that speeds up transaction processing and makes it easier for validators (network participants who confirm transactions) to operate. This builds on the 2024 Mysticeti V1 upgrade, which already achieved very fast transaction finality.
Why it matters: This improvement could attract more professional validators and improve network reliability, which is good for SUI’s long-term prospects. The success depends on a smooth rollout.

3. Remora Horizontal Scaling (2025)

What it is: A new scaling method that allows the network to handle over 100,000 transactions per second by adding more validator clusters, without needing extremely powerful computers (Bitget).
Why it matters: This positions Sui as a strong platform for high-demand applications like artificial intelligence and decentralized finance (DeFi), supporting future growth.

4. Security Expansion Program (2025)

What it is: A multi-year plan backed by $10 million to develop tools that prevent scams, simulate transactions for safety, and monitor for security threats (CryptoBriefing).
Why it matters: While this won’t immediately affect SUI’s price, it’s important for building trust, especially among institutional users.

5. SuiFest Singapore (October 2, 2025)

What it is: A flagship event where the Sui community will highlight new partnerships, developer tools, and projects (Sui Community).
Why it matters: Such events often increase network activity and attract new collaborators, which can positively impact SUI’s ecosystem.

Conclusion

Sui’s 2025 plans focus on making the network faster and more scalable (Mysticeti V2, Remora), safer, and more widely used through gaming and community events. Technical upgrades will help Sui compete as a Layer-1 blockchain, but growth in gaming and developer engagement will be key to increasing SUI’s real-world use. Keep an eye on how SuiPlay 0X 1 adoption progresses and the impact of SuiFest on developer activity. The big question remains: will these infrastructure improvements lead to sustained growth in total value locked (TVL) on the network?


What updates are there in the SUI code base?

Sui’s software updates focus on improving security, scalability, and making it easier for developers to build on the platform.

  1. Testnet v1.51.2 Security & Tooling (June 29, 2025) – Enforced TLS encryption and added “Party” objects for testnet transactions.
  2. $10M Security Overhaul (September 4, 2025) – Started a multi-year plan to fight scams and fix vulnerabilities.
  3. Move VM 2.0 Speed Boost (May 20, 2025) – Cut execution times by 30–65% through technical improvements.

Deep Dive

1. Testnet v1.51.2 Security & Tooling (June 29, 2025)

Overview: This update focused on securing communication between validators and making development smoother.

Key changes include mandatory TLS encryption for validator communication channels, which helps prevent unauthorized data access. The new “Party” objects, available only on the testnet, allow developers to experiment with new transaction types for decentralized finance (DeFi) and gaming applications. Developers also benefit from regex support in Move tests and faster project setup thanks to improved handling of Git dependencies.

What this means: This is a positive step for Sui. Stronger encryption reduces potential attack points, and faster development tools attract more builders. The “Party” objects could lead to innovative decentralized apps if they make it to the main network.

2. $10M Security Overhaul (September 4, 2025)

Overview: The Sui Foundation committed $10 million to improve security across the entire ecosystem.

This funding supports real-time threat detection, transaction simulation environments, and automated monitoring for exploits. It also includes screening for malicious decentralized apps and faster responses to impersonation attacks.

What this means: This is cautiously optimistic for Sui. While stronger security builds trust, this initiative was partly a response to a $220 million hack in May targeting the Cetus platform, showing ongoing risks in DeFi. These improvements could help reduce the impact of future attacks.
(Source)

3. Move VM 2.0 Speed Boost (May 20, 2025)

Overview: A major upgrade to the execution layer significantly improved network speed.

Move VM 2.0 reduced smart contract execution times by 30–65% through better bytecode processing. Additional improvements like parallel execution (Pilotfish) and validator scaling (Remora) increased overall throughput.

What this means: This is good news for Sui, as faster transactions make it more competitive with other blockchains like Solana. However, since this update came before recent market challenges, real-world testing under stress is still ongoing.
(Source)

Conclusion

Sui’s development is progressing on three fronts: strengthening security after hacks, speeding up core infrastructure, and supporting developers. The Move VM upgrade in May set the stage for better scalability, while new testnet features and security investments address emerging threats. With the launch of RPC 2.0’s REST API, it will be interesting to see how these improvements help speed up decentralized app development.
