What to know:

  • Polygon's proof-of-stake chain is experiencing a delay in transaction finality, running 10–15 minutes behind schedule.
  • The delay is due to issues with Bor/Erigon nodes and RPC providers, and a fix is being implemented.
  • Polygon's Heimdall v2 upgrade recently promised faster finality.
  • The disruption has affected the POL token's trading value.

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.

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.
