Polygon’s proof-of-stake chain is live, but transactions are taking longer than usual to lock in, with finality running 10–15 minutes behind schedule.
Finality is the assurance that a transaction or piece of data is irreversible once confirmed and added to a block in the blockchain.
The foundation said in an X post that a fix has been identified and is being rolled out to validators and service providers.
UPDATE: Temporary Delay in Finality
While the chain continues to run and blocks and checkpoints are produced, there is currently a 10-15 minute delay in finality due to a milestone issue.
We have identified a fix, and it is being rolled out to all validators and service…

The slowdown was tied to issues on some Bor/Erigon nodes and RPC providers, according to Polygon’s status page. Node restarts resolved the problem for many validators, while others had to rewind to the last finalized block before resyncing, a status page shared.
The disruption comes weeks after Polygon’s Heimdall v2 upgrade promised 5-second finality through a modernized consensus stack.
The network’s POL token traded lower alongside the incident, slipping around 3% to trade around 26 cents in early U.S. hours.
