Wyoming Makes Crypto History: Solana & Aptos Chosen for Groundbreaking WYST Stablecoin Launch

Wyoming just fired the starting gun on the next stablecoin race—and Wall Street didn't even get a lane assignment.

The Cowboy State's WYST stablecoin is going cross-chain with Solana and Aptos, bypassing legacy finance rails entirely. No banks. No middlemen. Just code enforcing dollar parity.

Why it matters: While D.C. regulators still debate frameworks, Wyoming's deploying live ammunition. The state's blockchain task force picked Solana for its blistering speeds and Aptos for its Move-language security—a one-two punch against settlement delays.

The fine print: This isn't some theoretical CBDC. WYST will be minted against actual Treasury holdings (take notes, Tether). Early access starts Q3 for approved institutional partners—assuming they can handle the irony of regulated DeFi.

Bottom line: When the first state-backed stablecoin goes live, it won't be on Ethereum. And the New York banking cartel just got served a Wyoming-shaped wakeup call.

TLDR

• Wyoming selected Solana and Aptos to launch its WYST stablecoin.

• Solana offers high speed and low fees for real-time payments.

• Aptos brings strong security and developer control.

• LayerZero enables WYST to move across 11 blockchains.

• Sei Network may join later after strong user growth.

Wyoming has officially selected solana and Aptos to host WYST, the first fiat-backed stablecoin issued by a U.S. state government. Powered by LayerZero’s cross-chain technology, WYST aims to deliver real-time, cost-efficient payments across multiple blockchain ecosystems. The selection cements Wyoming’s leadership in blockchain policy as it fast-tracks digital finance initiatives.

Solana Chosen for Speed and Transaction Efficiency

Wyoming’s Stable Token Commission awarded Solana top marks for its unmatched speed and cost-effectiveness. Solana enables WYST to function under high-frequency demands since it can process up to 65,000 transactions per second with average fees around $0.00025. These features are essential for retail, government, and institutional payment use cases.

The Commission emphasized Solana’s compatibility with critical infrastructure providers like Fireblocks and Chainalysis. These integrations ensure security, custody and compliance are maintained. Solana’s ability to handle stress tests and its latency performance made it a clear front-runner.

Aptos Selected for Security and Developer Flexibility

The Aptos blockchain, built with the MOVE programming language, offers high levels of upgradability and smart contract control. The Commission cited these as strategic advantages for WYST in maintaining regulatory compliance and technological longevity.

Aptos averages sub-second finality and processes over $30 billion in monthly stablecoin volume. The blockchain’s design aligns well with LayerZero’s Omnichain Fungible Token (OFT) standard, enabling native asset transfers without bridging or wrapping. This seamless inter-chain mobility reinforces Aptos’ role as a WYST deployment hub.

LayerZero Ensures Cross-Chain Operability

Wyoming integrated LayerZero’s cross-chain messaging protocol, allowing the stablecoin to move natively across supported networks. WYST testnet contracts have already launched on 11 blockchains, including Ethereum, Base, and Polygon.

LayerZero eliminates the need for wrapped assets and minimizes third-party risks. Solana and Aptos scored highest in readiness, vendor compatibility and operational performance, making them the first to go live. Full mainnet deployment is expected by August 2025.

Sei Shortlisted Amid Explosive Network Growth

Sei Network has also been shortlisted for consideration for WYST deployment. Last week, the platform experienced a significant surge in user activity, drawing the attention of the Wyoming Stable Token Commission. Sei’s performance metrics, particularly in transaction throughput and latency, impressed evaluators, placing it on the radar for future expansions of the WYST ecosystem.

Another massive week on Sei, where the Wyoming Stable Token Commission shortlisted SEI for its WYST Stablecoin Initiative, and network user numbers were smashed across the board.

The Commission continues to test WYST on various LayerZero-compatible blockchains. Sei’s substantial user numbers could position it as a secondary host or complementary LAYER in Wyoming’s multi-chain strategy.

Regulatory and Deployment Framework

WYST is authorized under the Wyoming Stable Token Act, passed in 2023. The token will be backed by U.S. dollar reserves held within the state under strict auditing and regulatory standards. The Commission evaluated 11 chains for cost, performance and integration support before finalizing Solana and Aptos.

WYST will integrate with Fireblocks for institutional custody and Chainalysis for monitoring and compliance. Wyoming also plans to secure trademarks for related digital instruments such as WEST and FRNT. The stablecoin’s debut is scheduled to be highlighted at the Wyoming Blockchain Symposium later this year.
