Polygon PoS Bridge and Ethereum Mainnet: State Synchronization Determinism
The Polygon PoS Bridge relies on a checkpointing mechanism where validators submit the latest Polygon block headers to the Ethereum mainnet to ensure finality and facilitate asset transfers. During periods of extreme network congestion on the Ethereum L1, the timing of these state root commitments may fluctuate. This creates uncertainty regarding the determi
polygonDoes the Polygon PoS bridge guarantee immediate post‑deposit state visibility after a checkpoint, or can RPC reads remain stale?
The goal is to determine whether, once a deposit transaction is included in a Polygon PoS checkpoint and that checkpoint is finalized on Ethereum, a read‑only eth_call to the user’s address on a Polygon node will always reflect the deposited balance, or whether a temporary stale‑cache window can still cause pre‑deposit reads. This depends on factors such as
