BSVKEY_FUNDED_SATS
No
The amount you funded your channel with on-chain. When set, usage receipts are verified against this instead of the broker-signed fundedSats. Optional (can be passed per call as fundedSats).
BSVKEY_RECEIPT_STATE
No
Path to a JSON file where per-channel receipt continuity (seq + running totals) is persisted, so replays are caught across restarts. Optional; in-memory only if unset.
