Safe Contracts v1.4.0 Deprecated Over ERC-4337 Bug
Safe has deprecated Safe Contracts v1.4.0 because of an important bug affecting ERC-4337 compatibility. Safe recommends using version 1.4.1 instead. The v1.4.0 changes were audited, with the report available through the project’s README, while bug bounty details are listed in the developer portal. Deployment addresses are available in the Safe deployments repository. Safe Contracts v1.4.0 remains available for use, but it will no longer receive support through Safe’s infrastructure. Traders should monitor applications and wallets using the older release for potential compatibility or security-related updates.
Neutral
The market impact is likely neutral because this is a software maintenance and security notice rather than a change to token economics, protocol incentives or network demand. The deprecation of Safe Contracts v1.4.0 could create short-term concern for developers and users whose wallets or applications rely on the release, particularly because ERC-4337 compatibility is linked to account abstraction and smart wallet functionality. However, the recommended upgrade to v1.4.1 limits the potential for prolonged disruption. Traders may briefly monitor SAFE-related sentiment, exchange activity and reports of affected deployments, but a broad market reaction is unlikely without evidence of exploited contracts, user fund losses or widespread service outages. Similar version deprecations in major crypto infrastructure projects have generally produced limited price impact unless accompanied by a confirmed security incident. Over the longer term, prompt remediation and audited releases could support confidence in Safe’s infrastructure, while continued use of the deprecated version may increase operational and compatibility risks.
