Stable has confirmed a mandatory mainnet upgrade to version v1.3.0, scheduled for May 13, 2026, as the protocol moves to reinforce execution safety, improve EVM consistency, and strengthen RPC reliability across its stablecoin-focused infrastructure.
The upgrade is non-backwards compatible and requires node operators and infrastructure providers to update before activation to avoid service disruptions, including potential issues with deposit and withdrawal flows.

Crypto network security is built on decentralization, cryptography, and consensus systems like Proof-of-Work and Proof-of-Stake, which help protect data integrity and prevent single points of failure.
However, major risks remain, including smart contract bugs, private key theft, bridge exploits, and 51% attacks, resulting in billions of dollars lost annually in Web3 breaches. To reduce risk, users and projects rely on cold wallets, multi-signature systems, audits, and real-time monitoring tools, while new trends like AI security and quantum-resistant cryptography are emerging to strengthen protection.
Security and Execution Layer Tightened
The update introduces stricter validation rules across transaction processing, including enhanced checks on sender, destination, and method selectors. Support for newer transaction formats, such as EIP-7702, has also been refined with improved authorization handling.
At the infrastructure level, RPC exposure has been tightened, with non-public namespaces disabled by default and signing APIs restricted to secure configurations. Input validation improvements, including stricter address formatting rules, aim to reduce the risk of malformed or malicious transactions.
Precompile execution has also been hardened, with restrictions placed on unknown methods and additional protections around low-level contract interactions to reduce unintended execution paths.
EVM Fixes and Node Reliability Improvements
The v1.3.0 release includes multiple fixes to improve execution consistency across the Ethereum Virtual Machine layer. These updates address gas accounting errors in failed precompile calls, refine refund logic in ERC-20 execution scenarios, and improve handling of warm-state precompiles.
Additional corrections include COINBASE opcode behaviour alignment and improved rollback consistency for EIP-7702 authorization flows.
RPC-level improvements focus on better reliability for indexers and applications, resolving inconsistencies in transaction responses, improving fee history logging, and ensuring chain ID accuracy in historical queries. The upgrade does not require state migration or a chain reset, and all existing data is preserved post-activation. However, nodes running outdated versions will cease to function after the upgrade height.
Meanwhile, network activity on Ethereum’s mainnet has overtaken that of major layer-2 scaling networks, as cheaper transaction fees draw users and possibly bad actors back to the base layer.
