Several edge fixes target gas accounts, ERC20 failure systems, COINBASE performance, and block early settlement.
As the global stablecoin market moves toward a breaking the record of $ 316 billion capitalizationthe infrastructure that has been put in place is undergoing a major “safety first” overhaul. This morning, the development team behind Stable announced the upgrade of the v1.3.0 Mainnet protocol, which is set to launch on May 13, 2026. This official, non-retroactive release is designed to transform the network into a stablecoin transaction highway, focused on execution security and network consistency.
Scheduled at approximately 07:00 UTC at altitude 24,077,500, the v1.3.0 update is very important. Following the latest legislative changes in the CLARITY Actwhich moved stablecoins closer to financial “plumbing”, the Stable protocol is strengthening its internal validation logic to protect against the edge threats that often plague high-profile blockchains.
Hardening the Execution Phase: EIP-7702 and Later
The central part of Stable Mainnet v1.3.0 upgrade is a major hardening of network security. The developers have introduced an additional system that determines not only the sender, but also the destination and selects the route. This integrated approach effectively closes the loopholes that can be used for smart collaboration.
Perhaps most importantly for the 2026 site, Stable is doubling down on its support for the EIP-7702, a concept that allows.external accounts (EOAs) to implement temporary smart contracts. The release of v1.3.0 brings a stricter check on the design and permission to run these forms. By combining the EIP-7702 authorization with the authentication process, Stable ensures that users going to “Smart Accounts,” their security remains firmly rooted in a proven, verified process.
EVM Reconfiguration and Protocol-Level Security
In addition to contract protection, the upgrade addresses a number of ongoing lawsuits Ethereum Virtual Machine (EVM) workstation. Notable fixes include gas accounting for failed calls and changes to refunds following internal failures of ERC20 calls – an important fix for stablecoin transfers that require high accuracy. The update also aligns with COINBASE opcode practices and the latest industry standards, ensuring that rewards and block-level data remain consistent across networks.
In order to improve the network in unexpected ways, Stable is introducing closed addresses, mainly based on the Prague precompile addresses. Unidentified authentication methods will now require query gas, a move that reduces the risk of a weak contract being used to leak network devices or bypass traditional security checks. This approach to “security software” is aimed directly at stakeholders who need the same level of predictability from blockchain that they expect from a legacy wireframe.
Improving RPC Reliability in Building Construction
For indexers, researchers, and backend developers, the RPC field is where the “real world” meets the blockchain. The v1.3.0 update brings much-needed reliability changes to this feature. This update ensures that non-public domains are no longer exposed by default, and API signing is sufficient for secure implementations. The address format now implements EIP-55 standards, adding checksum protection that helps prevent costly human errors during address entry.
The team has also fixed a number of system response issues – most notably fixing the “from = 0x0” error – and correcting incorrect rates in the currency profile. These changes are designed to provide a stable foundation for developers building the next generation of on the chain to eliminate goods that global payment companies such as Worldpay and Mastercard are now using the chain.
Service Plans for Node Users and Partners
Because v1.3.0 is a non-retroactive update, node users should take action before the May 13 deadline. Nodes running older versions after unlocking at block 24,077,500 will be removed from the network, losing the ability to update or sync new blocks.
Partners who do it themselves are advised to set up the new system in advance, especially if they are using tools like Cosmovisor for automatic updates. For those who manage nodes manually, the team recommends a planned reboot at the upgrade point to avoid any disruptions or releases. Importantly, the upgrade does not include chain reconfiguration or government migration; all existing data will be preserved, ensuring that end users and those with the $STABLE token are not affected.
The Era of Mature Stablecoin Infrastructure
The v1.3.0 upgrade is not just a patch; and words of intent. As Stable continues to be used in real world applications, the proven mobility and consistency of EVM shows the maturity of the protocol. By strengthening the network against today’s potential risks, Stable is positioning itself as the preferred multi-billion dollar global destination that is expected to continue to grow over the next five years.
For node operators and partners, the message is simple: change now or risk being left behind as the network enters its most secure and stable phase yet. The future of stablecoins is built on the safety net, and on May 13, the Stable is establishing a new gold standard.
