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`](./bor_getSnapshot.md) instead, which returns the validator set together with the recent-signers history. To resolve the proposer (author) of a *historic* block, use [`bor_getAuthor`](./bor_getAuthor.md).

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.
