Robinhood archive depth

How far back Robinhood Chain state and logs can be read through Triport: measured floors rather than a "full archive" claim, and what to do when a range is too deep.

Archive depth here is measured, not promised. The earliest measured state floor is block 55,782,445; another archive-capable channel begins at block 56,772,445 (direct-channel measurement, September 2026). Those are observations from specific channels at a specific time, not a contract that every historical block is readable.

What this means in practice

  • A state read (eth_getBalance, eth_call, eth_getStorageAt, eth_getProof) at a block below the floor of the serving channel fails rather than returning a silently wrong answer.
  • Depth can differ between channels, so a range that worked once is not guaranteed to work later. Treat a depth failure as an expected condition and retry with a shallower block, a narrower range, or your own stored data.
  • A full state archive from block zero is not confirmed for this network — do not design on that assumption.

Deep log ranges

eth_getLogs range and result ceilings depend on the serving channel. Triport may split a deep range or reconstruct it from block receipts; reconstruction is slower and can still fail when no eligible historical channel exists. Split wide ranges yourself, retry the failed slice, and treat a timeout as "narrow the range", not "no data". See eth_getLogs and Limits.

Do not trust eth_syncing for depth

eth_syncing is disabled on some channels, and where it answers, its result is not a trustworthy view of pool health or history coverage. Compare heads and data freshness instead of relying on it.

Building your own history

Blocks, receipts and logs are readable, and debug traces add internal-call detail on a best-effort basis — that is enough to build an index, but it is not a ready-made history API. Triport does not publish an indexed address history for Robinhood Chain; see address history. The sequencer feed is a live stream with a short operational replay window, not a source of historical replay.
