Polygon PoS reports delays of up to 15 minutes in finalizing transactions

• Polygon PoS faces 10-15 minute delay
• Block production continues normally during technical problem
• POL Token Falls 4% After Network Instability

Polygon reported on Wednesday that its proof-of-stake (PoS) chain is experiencing temporary delays in transaction completion, even though block production and checkpoints continue to operate normally. The issue is causing transactions to take between 10 and 15 minutes longer to be considered irreversible.

"While the chain continues to operate and blocks and checkpoints are being produced, there is currently a 10-15 minute delay in finalization due to a milestone issue," the Polygon Foundation explained in a post on X. The team said it has identified the cause and that a patch is being rolled out to validators and service providers.

UPDATE: Temporary Delay in Purpose

While the chain continues to run and blocks and checkpoints are produced, there is currently a 10-15 minute delay in purpose due to an issue.

We have identified a fix, and it is being rolled out to all validators and services…

Finality is the step that ensures that a transaction cannot be reversed, as its state has already been accepted by consensus. Although blocks are created in a few seconds, there is a residual risk of reorganization until finality is reached. Exchanges and DeFi protocols typically wait for finality before crediting deposits or releasing trades, making this delay especially relevant for transactions that require greater security.

Polygon is one of Ethereum's leading scalability solutions, enabling low-cost, high-throughput transactions. The network publishes periodic checkpoints on Ethereum, enhancing security. Various industries, including exchanges, gaming, and DeFi platforms like Polymarket, utilize its infrastructure to provide liquidity and efficiency.

The issue arises months after the implementation of the Heimdall v2 update, designed to reduce completion time to five seconds and modernize legacy components from 2018. After the hard fork, however, the network had already experienced an outage of about an hour, signaling technical challenges in stabilizing the infrastructure.

Amid the delay, the POL token, native to the Polygon network, fell about 4%, also following the broader cryptocurrency market downtrend on Wednesday. The foundation said it will continue publishing statements on its website. status page until the incident is completely resolved.
