Welcome to the seventh edition of The Stable Standard, where we share progress across the Stable network and how stablecoin-native infrastructure is moving from early adoption to continuous, real-world usage.

• Mainnet activity continues to scale, surpassing 1.15M transactions and 45,000+ addresses.

• The upcoming upgrade improves security, validation, and execution reliability

• The Stable documentation has been rebuilt from the ground up to improve the developer experience and reduce time to integration.

• Stable expanded its global presence across Web3 Festival Hong Kong and adjacent events.

• The next phase of upgrades will introduce parallel execution and deterministic transaction inclusion

• StablePay continues to progress toward enabling seamless, real-world USDT payments.

In April, Stable strengthened its execution layer with upcoming improvements focused on security, reliability, and developer experience. The near-term upgrade enhances transaction validation and execution safety, while a rebuilt documentation experience makes it easier for developers to go from integration to production.

At the same time, Stable expanded its presence across global conversations, with strong engagement on Web3 Festival Hong Kong and adjacent ecosystem events. These developments set the stage for the next phase of Stable, focused on higher performance, parallel execution, and predictable transaction execution at scale.

Stable is preparing the next upgrade, with planned improvements across transaction validation, RPC exposure, and execution safety.

Expected updates include:

• tighter RPC controls and safer signing configurations

• strengthened validation for system transactions and waiver inputs

• expanded protections around precompiles and execution paths

The upgrade also includes fixes aimed at improving EVM execution consistency and RPC behavior, such as:

• more accurate gas accounting in edge cases

• improved handling of internal call failures and rollback behavior

• better consistency in RPC responses and historical transaction data

Why it matters

These updates are designed to strengthen the execution layer and improve reliability for developers and applications building on Stable.

The Stable documentation has been rebuilt from the ground up to improve the developer experience and reduce time to integration.

The updated docs include:

• Quickstarts and Integration Guides for faster onboarding

• Wallet and Oracle references with clearer implementation paths

• refreshed content across core developer workflows

There is also a stronger focus on agentic workflows, including guidance on building agents that can accept payments on Stable.

Developers can now leverage the documentation directly as a knowledge base for agents, enabling faster integration of Stable capabilities into agent-driven systems.

Following the v1.2.0 upgrade, activity on Stable continues to scale as builders and early partners expand their deployments:

• 5,400+ smart contracts deployed

• 45,000+ total addresses

• 1.15M+ transactions processed

This sustained growth reflects increasing demand for stablecoin-native execution across payments, transfers, and settlement flows.

Post-upgrade, activity continues to trend upward, reinforcing Stable’s role as infrastructure for real-world, high-frequency payment environments.

This month, we introduced How Agents Pay, a series exploring how payment flows evolve as agents become active economic participants. As systems shift toward real-time, request-level interactions, payments are becoming part of the flow itself.

Stable simplifies this by enabling USDT for both gas and settlement, making high-frequency, agent-driven payments viable at scale.

This month, Stable expanded its presence across global industry conversations and ecosystem channels, with a strong focus around Web3 Festival Hong Kong and adjacent events, reinforcing its positioning at the intersection of stablecoin infrastructure and real-world payments

• At the Hong Kong Web3 Festival, our CEO Brian Mehler joined industry leaders across finance and crypto to discuss the future of cross-border payments and asset digitization.

  The conversation explored how payment infrastructure is evolving to support faster global settlement, and the role of stablecoin-native rails in enabling this shift.

• At RWA & Payments 2026 in Hong Kong, our CEO Brian Mehler joined a panel hosted by BenPay Global to discuss how RWAs are moving beyond issuance into real utility, liquidity, and payment flows.

  The discussion focused on how the next phase of tokenized assets will be defined by infrastructure, access, and real-world adoption. https://x.com/Stable/status/2046223651268448296?s=20

• Stable co-hosted the RWA DeFi & PayFi Summit during Web3 Festival discussions alongside Asseto Finance and dtcpay, bringing together builders and operators across RWAs, DeFi, and payments.

  Our CEO Brian Mehler delivered a keynote on how payment rails and stablecoins power the next phase of RWA adoption, highlighting the role of infrastructure in enabling real-world use cases.

  Brian also led a panel titled “RWA + PayFi: Stablecoin Payments and New Opportunities in On-Chain Asset Management,” alongside speakers from dtcpay, Billions Network, and Beosin. https://x.com/Stable/status/2046913298747273485?s=20

• At the HSC Asset Management conference, our CEO Brian Mehler joined leaders across the ecosystem to discuss the evolution of global liquidity rails and the infrastructure behind stablecoin-based financial systems.

  The discussion highlighted how settlement, compliance, and execution layers are shaping the next generation of global payments.

• At the Techub News event in Hong Kong, our CEO Brian Mehler presented “AI Agents, Real Money, New Rails,”exploring how agents move from intent to action with embedded payments.

  The session highlighted how real-time, programmable payments, powered by sub-second finality and gas-free USDT execution, enable agent-driven systems at scale.

StablePay is an upcoming payment app built on Stable, designed to make sending and receiving USDT globally as simple as using any modern payments app, but powered entirely by stablecoin infrastructure.

With StablePay, users will be able to:

• send USDT instantly to friends and family across borders

• pay globally in dollars without dealing with currency conversion friction

• transact without managing gas or multiple tokens

• rely on predictable, dollar-denominated transaction costs

Whether it’s sending money abroad, splitting expenses, or making everyday payments, StablePay makes global USD transfers seamless and accessible.

By combining stablecoin-native execution with a simplified user experience, StablePay brings the benefits of Stable into a consumer-facing application.

More updates are coming soon.

Stable continues to evolve its execution environment toward a system designed for continuous, high-frequency, machine-driven payments.

The next phase of mainnet development builds toward this, improving performance, execution guarantees, and support for real-time payment flows.

The next set of protocol-level upgrades introduces fundamental improvements to how transactions are executed and prioritized:

• Optimistic Parallel Execution (OPE) + MemIAVL
  Enables multi-core parallel execution, targeting up to ~10k TPS

• Selective RecheckTx
  Improves sustained throughput while reducing node CPU usage

• 2D Nonce
  Introduces parallel transaction lanes, removing sequential nonce constraints

• Guaranteed Blockspace
  Enables deterministic transaction inclusion with reserved capacity for priority flows

Together, these upgrades remove key bottlenecks in the block lifecycle and shift execution from probabilistic inclusion to protocol-level guarantees.

StablePay (Coming Soon)

• Consumer payments app for global USDT transfers

• Focused on seamless UX, gas abstraction, and real-world usage

Agentic Payment Infrastructure

• Continued support for x402-based flows

• Improved facilitator and settlement reliability

• Enabling high-frequency, API-level payments
