Key Highlights
- Polygon PoS stayed online despite node delays, with blocks produced normally and transactions continuing without interruption.
- RPC disruptions mainly affected Bor nodes, but Polygon quickly patched the issue, and validators are steadily syncing.
- Past incidents and hacks like Yala highlight ongoing network risks, yet user funds remained safe throughout Polygon’s downtime.
Polygon’s PoS network faced a technical hiccup this week that affected some of its nodes, causing a few delays for users. Despite the problem, the blockchain stayed online and blocks kept being produced uninterrupted.
The Polygon Foundation confirmed on X that the team was able to quickly detect the bug and release a patch to allow functionality to function fully. Validators are currently syncing, and the network is gradually building to achieve the required quorum. However, there have been partial disruptions in RPC services, although the flow of transactions has not been interrupted.
The disruption primarily affected Bor, Polygon’s block-producing and transaction execution layer. Polygon reported that multiple nodes stalled, impacting RPC availability across several providers. “The block producer remains operational and blocks are still being produced, meaning the chain itself remains live,” the team said.
A war room was activated to coordinate mitigation, and updates were shared continuously to keep users informed. Tuyo, a self-custodial crypto finance app, also reassured users: “All funds are safe, and we will update when normal functions return.”
RPC issue and previous slowdowns
This incident follows earlier RPC-related slowdowns. On December 12, Polygon noted that some transactions appeared stuck or missing. Users were advised to resubmit transactions with at least 10% higher gas prices. A fix was implemented, and the network began monitoring results to ensure full recovery.
RPC disruptions are not uncommon for Polygon, as seen in September when certain Bor and Erigon nodes delayed block finality by 10–15 minutes. Consequently, some validators and providers experienced temporary interruptions, although checkpoint validation continued within expected ranges.
The stalling RPC nodes had to go back to the last finalized blockchain, which was number 76,273,070, to sync properly. Fixes by the Polygon team have been introduced among all validators and service providers. Additionally, some nodes functioned normally despite the problem that occurred on the network.
Security context and current cases
Although the Polygon platform was stable throughout these incidents, security breaches on the blockchain reveal the risks that exist. In September, the DeFi service Yala lost more than $7.7 million as a result of a Polygon blockchain’s smart contract exploit.
This hack allowed the attacker to mint 120 million YU tokens, which the hacker then exchanged for USDC on the Ethereum and Solana blockchains. However, the service had to suspend the Convert feature on the Bridge service on the Yala protocol as a measure of caution. The service further maintained that “All other protocol functions are unaffected, and user assets are safe.”
These events show why it’s important to keep an eye on both network performance and smart contract safety. Polygon’s fast RPC fixes stopped bigger transaction problems, but the issue shows how problems with individual nodes can slow things down and cause headaches for users and apps.
