Short version: TVS (Total Value Shielded) is the operating metric that tells you whether your privacy stack works in production. When you can measure, raise, and defend TVS, you can ship private payments and procurement flows that pass audits, clear OFAC/KYT checks, and hit ISO 20022 deadlines—without derailing engineering.

The “Total Value Shielded” (TVS) Metric: Building for Privacy

Target audience: CFOs, Heads of Treasury/Procurement, and Compliance Engineering leads at fintechs, Web2 marketplaces, and payment institutions rolling out on-chain rails.

Intent keywords to satisfy stakeholder search and RFP language:

• Treasury/Procurement: ISO 20022 (pacs.008/pacs.009, camt.056/camt.029), three‑way match, vendor master hygiene, dual control, segregation of duties, SOX 404 control evidence, payment recalls/Case Management.
• Compliance: OFAC screening, KYT (Know Your Transaction), rulebooks for sanctioned association sets, auditability, selective disclosure.
• Engineering: EIP‑7701 (native account abstraction), FOCIL/EIP‑7805 inclusion lists, BN254/Poseidon on-chain ZK verification, shielded pool telemetry, HSM‑managed view keys, reproducible circuits.

Hook — The headache your team is living with

Your CFO wants on‑chain vendor payouts in USDC next quarter. Your CISO wants privacy by design (GDPR Art. 25) and audit‑ready logs. Compliance asks for “OFAC‑clean” flows and KYT outputs. Meanwhile, engineering is splitting cycles between ISO 20022 cutovers and wallet plumbing—and you still have no single metric that proves your privacy pipeline is doing anything beyond demo environments. (gdpr-info.eu)

You can’t manage what you can’t measure. Without a production‑grade privacy KPI, you’re flying blind: you can’t forecast liquidity in shielded addresses, you can’t size anonymity sets for procurement runs, and you can’t prove ROI to the board.

Agitate — What’s actually at risk

• Missed industry deadlines and rework:
  • SWIFT coexistence ended November 22, 2025; contingency translation now adds fees/friction. If your privacy flows don’t map to ISO 20022 case management (camt.110/111) and recalls (camt.056/029), you burn cycles building one‑offs under audit pressure. (swift.com)
  • Fedwire’s ISO 20022 go‑live (July 14, 2025) forced message remodels; any private payment wrapper that can’t carry rich remittance data means reconciliation breaks in ERP. (frbservices.org)
• Censorship and “stall risk” on L1/L2:
  • Ethereum core devs pushed FOCIL (EIP‑7805) to front‑burner status for Hegotá to counter transaction filtering; until those guarantees land, privacy transactions can be deprioritized by builders/relays. Translation: your private payouts may hang at the worst possible time. (eips.ethereum.org)
• Policy whiplash if you choose the wrong primitive:
  • OFAC’s 2025 Tornado Cash delisting changed the compliance surface. The lesson isn’t “use mixers”—it’s: build privacy with selective disclosure/KYT‑compatible proofs (e.g., Privacy Pools’ association sets), so policy shifts don’t brick your stack. (home.treasury.gov)
• Liquidity and pricing blind spots:
  • Zcash shows how fast “shielding” can drain tradable float; shielded supply hit ~30.4% on Feb 9, 2026—great for privacy, but a real consideration for OTC and treasury operations planning slippage/availability. If you don’t track TVS, you misprice execution windows. (zkp.baby)

Solve — 7Block Labs’ TVS‑first methodology

We make privacy measurable, compliant, and shippable. Our approach couples protocol‑level ZK engineering with procurement and treasury outcomes. Start here:

1) Define TVS precisely for your stack

TVS (Total Value Shielded) is the notional value of assets currently held in addresses/notes that meet your privacy policy and disclosure posture.

• UTXO/privacy L1s (e.g., Zcash): TVS = Sprout + Sapling + Orchard balances minus known self‑change; stratify by pool to reflect proving systems. Track “Shielded Percentage” as TVS / Circulating Supply. (zkp.baby)
• EVM privacy apps (Railgun, Privacy Pools): TVS = protocol “private balance” across supported assets eligible for selective disclosure (e.g., proofs of association/innocence). Keep a separate “Compliant TVS” that excludes quarantined/flagged association sets. (medium.com)
• Enterprise L1s adding native ZK (Stellar Protocol 25 “X‑Ray”): TVS = assets locked behind ZK‑verified flows with view‑key escrow policy in place (BN254/Poseidon‑based verification). (stellar.org)

Operational derivatives we instrument on day one:

• Shielded Coverage Ratio (SCR): TVS / Total On‑chain Float (by asset).
• Effective Anonymity Set (EAS): unique notes/commitments within your policy‑approved association sets over a rolling window (e.g., T‑30).
• Shielded Turnover (STO): 30‑day private inflow/outflow ÷ TVS; detects “stale” pools that need liquidity seeding or fee tuning.
• Compliant Utilization (CU): share of private payments accompanied by KYT‑clean association proofs and signed attestations.

These become the “money metrics” your CFO and CISO review alongside cash forecasts.

2) Instrumentation: from node to ERP

We deploy a minimal, auditable data plane:

• Indexers and provers
  • ZEC: ingest from zkp.baby parity (Orchard/Sapling) with our verifier to avoid stale snapshots; bind to block heights for dispute resolution. (zkp.baby)
  • EVM: event‑sourced listeners for Railgun “0zk” notes and Privacy Pools’ Merkle sets; maintain a policy engine for association‑set inclusion/exclusion rules that compliance owns. (medium.com)
  • Stellar Soroban: on‑chain BN254/Poseidon verification receipts for zero‑knowledge proofs, tied back to internal vendor IDs. (stellar.org)
• KYT + selective disclosure
  • Enforce proofs‑of‑innocence/association on private withdrawals. Archive “proof receipts” with nonces and circuit hashes for audit (no PII on-chain). (globenewswire.com)
• ERP connectors
  • ISO 20022 payload mappers for pacs.008/009; camt.056/029 (recalls); case management (camt.110/111) so private transfers still reconcile and can be recalled with an audit trail. (swift.com)
• Key management
  • HSM‑backed view keys under dual control; rotation SLAs; selective reveal workflows keyed to subpoena/FPCA processes.

Where we plug in:

• Need engineers who have built this before? Our custom blockchain development services and web3 development services ship the indexers, circuits, and policy engine.
• Want integrations that don’t break your back office? Our blockchain integration team maps ISO 20022 and ERP schemas end‑to‑end.

3) Choose the right primitives for 2026

• Ethereum (today/tomorrow):
  • EIP‑7701 (native AA) unlocks “sponsor gas privately” flows—critical for paying vendors from shielded balances without doxxing your fee payer. Plan for AA‑native wallets and paymaster policies. (eips.ethereum.org)
  • FOCIL/EIP‑7805 moves censorship resistance into fork choice; until it ships, model “stall risk” on private txs and pre‑fund time buffers in disbursement runs. (eips.ethereum.org)
  • Privacy Pools for compliant privacy and attestation receipts; we integrate 0xbow’s ASP outputs so Compliance can tune rulebooks. (globenewswire.com)
• Zcash:
  • An enterprise‑grade privacy baseline; shielded percentage has broken above 30% at times, indicating deep anonymity sets for sensitive treasury moves. Build playbooks for Orchard‑only flows to standardize proof systems. (finance.yahoo.com)
• Stellar:
  • Protocol 25 (“X‑Ray”) adds BN254 and Poseidon; for regulated payment corridors that already speak ISO 20022, this is a pragmatic home for private remittance with first‑party ZK verification. (stellar.org)

Where we plug in:

• Evaluating a privacy L2 or compliant mixer alternative? Our cross‑chain solutions development, DeFi development services, and smart contract development teams benchmark latency, proof costs, and CU% across options.
• Hardening before go‑live? Use our security audit services to review circuits, view‑key custody, and proof receipt trails.

4) Make TVS drive procurement and treasury ROI

Tie TVS directly to business levers:

• Procurement
  • Objective: keep sensitive vendor terms private while preserving recallability and SOX 404 evidence.
  • Mechanism: pay via Privacy Pools or Railgun from shielded balances, attach association‑set attestations; log ISO 20022 remittance data off‑chain; pre‑stage camt.056 recall payloads for exception handling. (finance.yahoo.com)
  • KPI: CU% ≥ 98% across payouts; median disbursement time under p95 target even under mempool stress (FOCIL not yet active). (blog.ethereum.org)
• Treasury
  • Objective: minimize information leakage and slippage on large rebalance moves.
  • Mechanism: schedule “dark rebalances” into shielded pools where anonymity sets (EAS) exceed threshold; back out through compliant withdrawal windows.
  • KPI: SCR trend and STO bands flag when to add LP/market‑maker support before a campaign (e.g., ZEC case highlights float shrink when shielding surges). (zkp.baby)

Where we plug in:

• We deliver TVS dashboards, EAS/STO/CU monitoring, and playbooks through our asset management platform development.

5) A 90‑day blueprint (no archaeology, just shipping)

• Weeks 1‑2: Privacy posture and policy modeling (association sets, reveal triggers); map ISO 20022 touchpoints; define KPIs (TVS, EAS, CU, STO).
• Weeks 3‑6: Stand up indexers, proof receipt store, KYT adapters; wire paymasters/AA for private gas where applicable; implement HSM view‑key ops.
• Weeks 7‑10: Pilot vendor payouts on test assets; run failover drills (recall, stall, censorship); tune mempool/fee policies.
• Weeks 11‑12: Security review and red‑team; signoff on control narratives; migrate first production cohort.

Prove — Market signals and GTM metrics you can copy

Evidence that TVS is the right north star for privacy adoption:

• Zcash’s shielded value as a network‑level TVS indicator:
  • Shielded percentage reached ~23% by Nov 2025 and crossed ~30% at peaks; as of Feb 9, 2026 the dashboard shows Shielded Percentage ~30.4% and Total Shielded Value ~5.03M ZEC. This indicates a durable user shift to private balances—i.e., real privacy utility, not just marketing. (theblock.co)
• Railgun’s TVS/usage momentum:
  • Project‑reported “value held in 0zk addresses” climbed from ~$14M (Jan 2024) to ~+$90M (Dec 2024); all‑time shielded volume later surpassed $4B, boosted by Ethereum Foundation’s Kohaku wallet integration—a strong signal of mainstream wallet‑level privacy UX. GTM lesson: build where wallets can make privacy the default. (medium.com)
• Compliant privacy productization:
  • Privacy Pools launched on Ethereum mainnet in 2025, added stablecoin support, and shipped an “Association Set Provider” (0xbow) model for KYT‑friendly proofs—exactly the pattern enterprises need to defend privacy without mixing with tainted funds. Early usage (>$6M, 1,500 users) is small but directionally right—measure it as Compliant TVS. (rootdata.com)
• Protocol‑level privacy plumbing for payments:
  • Stellar’s Protocol 25 (“X‑Ray”) brought BN254/Poseidon primitives on‑chain in January 2026 (testnet Jan 7; mainnet vote Jan 22), enabling in‑contract verification of ZK proofs—making selective disclosure easier to integrate alongside ISO 20022 flows. GTM lesson: when the L1 speaks ZK natively, your TVS can grow without UX tax. (stellar.org)
• Regulatory posture is evolving toward selective disclosure:
  • After court challenges, OFAC delisted Tornado Cash in March 2025; regardless of views, the strategic takeaway is to design for attestable innocence rather than opaque mixing, so policy changes don’t crater your TVS. (ofac.treasury.gov)

What to put on your GTM dashboard next quarter:

• TVS growth rate (net of quarantined funds) by asset and corridor.
• EAS threshold breaches vs. planned payout batches.
• CU% by vendor tier and geography (prove “privacy with compliance”).
• ISO 20022 exception rate on private payments (recalls, case management).
• Stall risk tracking vs. mempool stress (until FOCIL lands), with p95 time‑to‑finality SLOs. (blog.ethereum.org)

Practical examples you can adapt this month

1. Private vendor payouts with recallability (USDC on Ethereum)

• Flow: Fund a shielded balance; batch supplier invoices; for each payout generate a Privacy Pools proof + association‑set attestation; submit via AA paymaster to avoid doxxing your fee payer; archive the proof receipt + ISO 20022 remittance off‑chain. Maintain camt.056 templates for exception recalls. Track CU% and p95 finality. (eips.ethereum.org)
• Why it works: You get “privacy with an audit button”—view keys under dual control, attestation receipts for compliance, and recall pipelines aligned with ISO timelines.

1. Dark treasury rebalance (ZEC)

• Flow: When EAS > threshold and STO in band, move tranches into Orchard; exit with proof‑of‑innocence windows aligned to desk availability; monitor TVS drift so you don’t get trapped by liquidity crunch. (zkp.baby)
• Why it works: You ride deep anonymity sets while keeping liquidity risk explicit to OTC ops.

1. Regulated corridor pilot (Stellar)

• Flow: Use Soroban contracts with BN254/Poseidon to verify ZK proofs of eligibility while keeping amounts/beneficiary private to parties of interest; embed ISO 20022 IDs for straight‑through reconciliation. (stellar.org)
• Why it works: Native ZK plus ISO 20022 alignment is how you satisfy treasury, compliance, and engineering in one shot.

Where we plug in:

• Build and ship the above with our cross‑chain solutions development, blockchain bridge development, and dApp development teams.

Emerging best practices (brief, in‑depth notes)

• Prefer “attestable privacy” over mixers:
  • Association sets (Privacy Pools) + KYT give you a defensible line with auditors, even as regulatory winds shift. Make attestation receipt storage a first‑class artifact in your evidence locker. (rootdata.com)
• Engineer for censorship resistance:
  • Until FOCIL, budget buffers for private tx inclusion, and monitor mempool vendors. As FOCIL/AA mature, plan migrations to AA‑native wallets and enforce paymaster policies. (eips.ethereum.org)
• Treat view keys like production secrets:
  • HSM custody, dual control, rotation cadences, and “n‑of‑m” disclosure processes bound to legal triggers. Log only proof receipts, not plaintexts.
• Map privacy to ISO 20022 from day 1:
  • If your private payment can’t produce camt.110/111 case artifacts or camt.056/029 recalls, you will fail operational readiness reviews. (swift.com)
• Publish TVS monthly to your execs:
  • TVS, EAS, STO, and CU% should sit next to cash forecasts and AP aging. When TVS rises and CU% stays >98%, your privacy GTM is working.

• Need zero‑to‑one buildouts? Our blockchain development services team handles circuits and contracts; security audit services de‑risk go‑live.
