bor_getCurrentProposer

Last updated:

bor_getCurrentProposer returns a single 0x-prefixed address: the signer of the validator that is the current block proposer on Polygon. This is part of the bor namespace — Polygon's Bor (Proof-of-Stake) consensus extension — and is not exposed by standard EVM/Geth methods.

The proposer rotates every block (Polygon block time is ~2.1s), selected by stake weight within the active validator set. Because the answer changes so frequently, this method is best suited to real-time "who is proposing right now" lookups — for example, MEV pre-confirmation logic or live validator dashboards. Poll it once per block at most; the value is stale almost immediately after it is read.

If you need the full proposer schedule for an epoch rather than the single current proposer, call bor_getSnapshot instead, which returns the validator set together with the recent-signers history. To resolve the proposer (author) of a historic block, use bor_getAuthor.

This is a bor-namespace method available on the Pro tier and above. It is rate limited per tier with a short burst allowance; there is no daily quota.
