Transaction Finality Lag Hits Polygon PoS, Developers Working on Fix

Polygon PoS Sees Transaction Finality Delays; Patch in Progress
10/9/2025

Polygon’s proof-of-stake (PoS) network is experiencing delays in transaction finality, with confirmations running 10–15 minutes behind schedule, though block production continues as normal.

Finality ensures a transaction is irreversible once confirmed on the blockchain. The slowdown has been traced to a bug affecting certain Bor/Erigon nodes and RPC providers, forcing some validators to resync from the last finalized block. Node restarts fixed the issue for many validators, while others required a full resynchronization.

The Polygon Foundation confirmed on X that a patch has been identified and is being rolled out to validators and service providers.

The incident comes weeks after the Heimdall v2 upgrade, which promised 5-second finality via a modernized consensus stack. POL, the network’s native token, slipped roughly 3% in early U.S. trading, trading around $0.26 amid the network slowdown.
