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 infra batches 10,000 verified impressions every 5 minutes. The publisher — also on Salesforce — needs same-cycle settlement, 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 landed on the matching Account and Contract.

Audit: any party can recompute the batch hash from the impression manifest and verify the Ed25519 signature. CPM contract terms become reconcilable 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

Reconcile a batch — recompute the manifest hash, verify the on-chain tx

# 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.
