SUI Advances: Open Wallet Standards and AI-Powered Payments Shape Future Agentic Commerce

• Sui's DeFi ecosystem has grown to a Total Value Locked (TVL) of nearly $2 billion, with 10% attributed to Bitcoin-related assets, indicating strong institutional and retail confidence in the blockchain's infrastructure and cross-chain utility.

• 21Shares has launched a spot SUI ETF in the United States, offering regulated exposure to the SUI token and potentially enhancing liquidity and market accessibility for institutional investors.

• MoonPay's Open Wallet Standard (OWS) enables AI agents to securely manage blockchain transactions across multiple chains without exposing private keys, fostering secure and interoperable transactions for the agent economy.

Sui's DeFi ecosystem is maturing rapidly, with the TVL reaching a significant milestone of $2 billion. This growth is largely driven by the integration of Bitcoin-related assets, which now make up 10% of the TVL. The inclusion of these assets signals increasing institutional and retail confidence in Sui's infrastructure and its ability to attract regulated capital.

The broader 2026 altcoin ETF race includes major asset managers filing for SUI-specific ETFs. These products aim to bridge the gap between traditional and decentralized finance, potentially unlocking new capital flows and enhancing liquidity. However, regulatory hurdles remain for certain tokens, particularly those lacking a history of live futures products. Approval timelines could take up to a year, introducing uncertainty for investors.

MoonPay's Open Wallet Standard (OWS) introduces a modular, open-source wallet infrastructure for AI agents. It supports secure transaction signing and key management across multiple blockchains, with contributions from over 15 organizations. The OWS is MIT-licensed and includes sub-specifications for storage, signing, and policies, aiming to address challenges in standardization and regulatory compliance for the agent economy.

Trust Wallet has also made strides in AI-powered finance by launching its Agent Kit. This tool allows AI agents to execute real crypto transactions across more than 25 blockchains while keeping users in control of their wallets. Users can define permissions for AI activity, and transactions either require user approval or follow pre-set rules. This infrastructure supports the execution of automated strategies such as dollar-cost averaging and limit orders.

Grayscale has introduced the SUI staking ETF (GSUI), enabling institutional investors to participate in the Sui network without directly holding the native token. The initiative aims to align investor incentives with the security and performance of the Sui blockchain. However, technical constraints and potential volatility from a large token unlock in March 2026 could affect market stability and decentralization.

Sui's price is currently consolidating near $0.97 with a neutral technical setup. A breakout above $0.99 resistance could drive SUI toward $1.06 and potentially $1.15 if momentum sustains. However, failure to hold above $0.99 could result in a decline to $0.91. Traders should monitor volume and RSI for confirmation.

What Is Driving Sui's TVL Growth in 2026?

The rise in Sui's TVL is driven by the integration of Bitcoin-related assets into its DeFi ecosystem. These assets allow for more diverse yield strategies and liquidity provision, indicating a maturing DeFi landscape where traditional finance is increasingly seeking exposure to specific altcoins through regulated products. The inclusion of these assets strengthens the bridge between the Bitcoin network and high-performance Layer 1 blockchains, enabling more sophisticated DeFi strategies.

In addition to Bitcoin-related assets, the broader 2026 altcoin ETF race has contributed to growing institutional interest in Sui. Major asset managers like Bitwise, 21Shares, VanEck, and Canary Capital are filing for SUI-specific ETFs, aiming to provide regulated exposure to the token. These products could significantly stabilize price action and expand market accessibility, though regulatory uncertainties persist.

How Are AI and Open Wallet Standards Shaping Sui's Future?

MoonPay's Open Wallet Standard (OWS) is playing a crucial role in shaping the future of agentic commerce on Sui. This infrastructure allows AI agents to securely manage blockchain transactions across multiple chains without exposing private keys, fostering interoperable and secure transactions. The standard is MIT-licensed and includes sub-specifications for storage, signing, and policies, addressing challenges in standardization and regulatory compliance for the agent economy.

Trust Wallet's Agent Kit is also contributing to the development of AI-powered finance on Sui. This tool enables AI agents to execute real crypto transactions across more than 25 blockchains while maintaining user control over wallets. Users can define permissions for AI activity, and transactions can be executed based on pre-set rules. This infrastructure supports the execution of automated strategies like dollar-cost averaging and limit orders, enhancing the user experience and expanding the capabilities of the Sui ecosystem.

What Are the Risks and Limitations Facing SUI?

While Sui's TVL growth and institutional interest are positive developments, there are several risks and limitations that investors should be aware of. One of the key challenges is the technical constraints that limit validator diversity and long-term sustainability. Sui faces potential volatility from a large token unlock in March 2026, which could introduce uncertainty into the market. These factors could affect market stability and decentralization, posing structural risks to the network.

The regulatory environment is another area of concern. Approval timelines for SUI-specific ETFs could take up to a year, introducing uncertainty for investors. Additionally, certain tokens lack a history of live futures products, which could hinder regulatory approval and market acceptance. These regulatory hurdles may impact the growth and adoption of Sui's DeFi ecosystem in the near term.
