DSP agent pays a publisher agent per verified impression batch

10,000 impressions verified, hashed, settled in one Nano call. The CPM is cryptographic.

01Scenario

A demand-side platform (DSP) running on Salesforce-fronted infrastructure batches 10,000 verified impressions every 5 minutes. The publisher, also on Salesforce, needs to get paid in the same cycle, not net-60.

The DSP agent computes a batch hash over the impression manifest (impression_id, viewability tier, brand-safety check). HiveNanoSettle.settle moves batch_count × CPM ÷ 1000 in micro-USDC on Base. The publisher's Salesforce org sees the inbound receipt land on the matching Account and Contract.

To audit it, anyone can recompute the batch hash from the impression manifest and check the Ed25519 signature. CPM contract terms become something you can reconcile on-chain.

List<ImpressionEvent__c> batch = [SELECT Id, Viewability__c, BrandSafe__c, ImpressionId__c
                                   FROM ImpressionEvent__c
                                   WHERE Batch__c = :batchId];

String manifestJson = JSON.serialize(batch);
String batchHash    = HiveHash.sha256(manifestJson);

Map<String, Object> payload = new Map<String, Object>{
  'batch_id'         => batchId,
  'count'            => batch.size(),
  'manifest_hash'    => batchHash,
  'cpm_usd'          => 4.50,
  'viewability_tier' => 'MRC_70',
  'contract_id'      => activeContractId
};

Long microUsdc = (long)(batch.size() * 4.50 / 1000.0 * 1000000);  // 10000 * 4.50 / 1000 = $45 = 45,000,000 micro

HiveNanoSettleResult res = HiveNanoSettle.settle(
  activeContractId,
  'impression.batch.settle',

  microUsdc,
  'salesforce:contract:' + activeContractId,
  payload
);

// receipt.Settlement_Amount_Micro__c = 45000000
// publisher's org gets a verified inbound receipt + tx hash

06Verification

To reconcile a batch, recompute the manifest hash and check the on-chain transaction

# Recompute hash from manifest export
jq -c . manifest_batch_77821.json | sha256sum
# expected: 7c11a2... (matches payload.manifest_hash)

# Verify on-chain
curl -sS https://api.basescan.org/api?module=transaction\&action=gettxinfo\&txhash=0x7d22...91bc | jq .result.value

07Economics

Per-batch tx	~$0.0003 Base gas
CPM moves on-chain	Buyer + publisher agree CPM; batch settles to USDC directly
Throughput	One batch per scan cycle, no monthly close
Hive take	0%
Disputes	Counter-receipt impression.batch.dispute reverses the settlement; manifest hash decides
MRC compliance	Viewability tier encoded in payload

08Compliance and audit shape

MRC accreditation friendly: viewability tier + brand-safety attestation are signed and hashed.
GDPR scope: impression ids can be pseudonymous; receipt only stores hashed batch manifest.
Settlement_Amount_Micro__c is the audit number. CPM × count = the on-chain transfer, no spread.
