1. Read the record from chain

cast call 0xE3c261F3C05D4c4710003cd6066EfD95094cf5f0 \
  "getRecord(bytes32)" \

  --rpc-url https://mainnet.base.org

2. Inspect via the indexer JSON API

curl -s https://www.protean.sh/ledger/api/v1/records/0xe3844dfd129baf4b19e970a9dfa393f92d4089e268acd1503dc5d46c77d3cf17 | jq

3. Reproduce the canonical state digest from genesis

curl -sL https://raw.githubusercontent.com/proteanlabs1/ledger-mirror/main/scripts/index_ledger_from_genesis.py -o index.py
python3 index.py --rpc https://mainnet.base.org \

# Compare against https://www.protean.sh/ledger/api/v1/indexer/digest

4. Confirm published indexer digest

curl -s https://www.protean.sh/ledger/api/v1/indexer/digest | jq '.digest, .record_count, .last_block'

Verification

What we can attest to from indexer state. Replay-artifact + content-digest verification you run yourself — see the verify page for copy-pasteable shell snippets and the public mirror for the canonical reproducibility script.

Replay pointer

Replay artifact: Not provided

This on-chain record is indexed, but no external replay artifact pointer was attached. Chain identity, transaction, and indexer checks still apply; the replay artifact was omitted at publication time and should be treated as a legacy missing-replay record.
