0x2a6f84fA0a09b1c04F9edAccCF6De58F11a4a364Stored on Base mainnet · chainId 8453
This record lives on the ProteanLedger UUPS proxy at 0x2a6f84fA…a4a364. The chain is the source of truth — the explorer is a read-only lens.
Four commands. Two terminals. No login. No wallet. No trust in Protean Labs required.
1. Read the record from chain
cast call 0x2a6f84fA0a09b1c04F9edAccCF6De58F11a4a364 \ "getRecord(bytes32)" \ 0x83542e023c23b56c8b68864e39918a9eee8dbfcc835f44cf23ef9326fc5e7e6d \ --rpc-url https://mainnet.base.org
2. Inspect via the indexer JSON API
curl -s https://www.protean.sh/ledger/api/v1/records/0x83542e023c23b56c8b68864e39918a9eee8dbfcc835f44cf23ef9326fc5e7e6d | 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 \ --proxy 0x2a6f84fA0a09b1c04F9edAccCF6De58F11a4a364 \ --db /tmp/protean.db --from-block 46612390 --once python3 index.py --digest-only --db /tmp/protean.db # 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.
Citable aggregation of the three mainnet bootstrap records: the genesis runtime cycle, the activation milestone runtime cycle, and the reproducibility hypothesis. This asset is the canonical handle for the Protean Ledger launch. It will be superseded by future versions as the operational record grows.

No on-chain descendants yet. This record is the most recent in its lineage.
Artifact mirror was introduced after this record was registered. Chain identity, content digest, lineage, and indexer reproduction verification all remain available. Public artifact sha256 verification was not available at registration time; the mirror carries an honest reconstruction in artifacts/mainnet/ with documented limitations.
