Brief: We compress 60–90 day royalty cycles into T+1 real-time, compliant USDC streams with verifiable usage proofs and automated splits—bridging Solidity+ZK under enterprise controls (SOC2, SLAs, procurement-ready). The result: lower working-capital drag, fewer disputes, and direct-to-fan economics at sub‑cent fees on Ethereum L2s.

Music Royalties: Direct-to-Fan Payment Rails

Target audience: Enterprise (labels, publishers, DSPs, PROs). Keywords embedded: SOC2, SLAs, procurement, DDEX, ISRC/ISWC, ROI.

Pain — Your royalty system is accurate on paper and late in real life

• DSPs still report and settle on a 60–90 day lag; you wait months to move dollars from usage files through accounting to payees, starving working capital and poisoning creator trust. (helpdesk.revelator.com)
• Policy changes keep moving the goalposts: Spotify’s 2024 threshold excludes tracks under 1,000 annual streams from the recorded royalty pool—tiny payouts vanish into pool reallocation unless you redesign your micro‑payout mechanics. (support.spotify.com)
• Metadata drift and mismatches (ISRC vs. ISWC/IPI) cascade into unclaimed or misallocated money; fixing it post‑hoc across ERN/DSR flows is slow and expensive under audit. (isrc.ifpi.org)
• Compliance friction is rising: procurement needs SOC2/ISO controls; compliance needs sanctions screening (OFAC, UK, EU); finance needs deterministic, audit‑ready payout trails. (trmlabs.com)

Agitation — The hidden costs stack up

• Missed deadlines: quarterly bulk runs accumulate edge-case tickets (splits, reversals, tax holds). Each delay compounds as catalog grows and as DSP policy shifts (noise tracks, artificial streams) trigger retroactive adjustments. (artists.spotify.com)
• Leakage and disputes: without verifiable, line‑item proofs from usage to split to payment, disputes last weeks; CFOs hold reserves “just in case,” and payees discount future royalties in financing deals.
• Fee drag: ACH/wire cross‑border costs make small payouts uneconomic; at scale, that’s millions in breakage or delay. Meanwhile, L2 onchain transfers and swaps are sub‑cent after Ethereum’s Dencun (EIP‑4844) rollout—if you can harness them safely. (l2fees.info)
• Strategic risk: if you cannot support “fan‑powered” or direct‑to‑creator constructs, you lose mid‑tail talent to platforms that let fans’ dollars route to creators they actually listen to. (press.soundcloud.com)

Solution — 7Block’s Direct‑to‑Fan Payment Rails (Solidity + ZK, procurement‑ready)

We build a production‑grade rail that ingests DDEX usage, proves the math, and settles to rights‑holders in USDC with automated splits and real‑time streams—while meeting enterprise controls.

1. Metadata and usage integrity layer (DDEX‑first)

• ERN 4.3 ingestion with MEAD/PIE hooks; upgrade plan for ERN v3/4.0 deprecations (support ends Mar 1, 2026).
  • Why it matters: fewer unmatched lines; deterministic lookups linking ISRC (recording) with ISWC/IPI (work/parties). (ddex.net)
• MLC usage pipeline: DDEX DSRF as default; SURF when needed; 37 CFR 210.27 compliance baked in. (themlc.com)
• Data contracts: schema validation and “release‑specific” metadata rules to avoid silent drift (e.g., DisplayArtistName variants). (kb.ddex.net)

1. Verifiable revenue attestations (ZK for auditability without exposing fan PII)

• We compute per‑asset revenue aggregates off‑chain and attach a ZK proof that “the sum equals the on‑chain remittance” using Proof‑of‑SQL style attestations (sub‑second provers; BigQuery integration).
  • Impact: compliance can independently verify that payouts match usage, without revealing raw DSP lines. (cloud.google.com)

1. Settlement core — USDC rails with gasless UX and cross‑chain reach

• Token: USDC for stable, fiat‑equivalent accounting and bank‑friendly off‑ramps.
• Authorizations: EIP‑3009 (receiveWithAuthorization) and Permit/Permit2 flows, so creators can approve pulls or one‑time signatures without wrestling allowances. (eips.ethereum.org)
• Gas abstraction: Circle Paymaster lets recipients pay gas in USDC on major EVM L2s; we remove “where do I get ETH?” support tickets. (circle.com)
• Cross‑chain treasury: Circle CCTP V2 (burn‑and‑mint) to move USDC natively across Base/OP/Arbitrum/Solana/Starknet, enabling low‑fee distribution while keeping one canonical USDC, not wrapped variants. (circle.com)
• Enterprise signal: Visa enabling USDC settlement with U.S. issuers creates compliance comfort for finance and procurement. (usa.visa.com)

1. Smart contracts — automated splits and streaming

• Splits: immutable split contracts (e.g., 0xSplits‑style) or your preferred audited splitter; ERC‑721 “stream NFTs” for transferability if needed.
  • Useful for producer points, featured artists, and publishers; supports automatic distribution on receipt. (blog.sablier.com)
• Streaming options:
  • Superfluid “Money Streaming” (by‑the‑second) for real‑time income to creators, catalog financiers, or pay‑per‑use APIs. (docs.superfluid.org)
  • Sablier v2 “Lockup/Flow” for vesting and open‑ended payments with non‑linear curves and batch operations. (blog.sablier.com)
• L2 cost base: after EIP‑4844, typical token transfers/swaps on major L2s are cents to sub‑cents—making micro‑royalties economical at scale. (l2fees.info)

1. Compliance, security, and procurement

• SOC2‑aligned controls: environment segregation, change management, audited libraries, formal verification where warranted.
• Sanctions screening: integrated KYT/wallet screening (OFAC, UK, EU). Programmatic blocklists pre‑transaction; alerts post‑transaction. (chainalysis.com)
• Contract security: static analysis, differential fuzzing, and third‑party audits; we align to your vendor risk questionnaire and provide SLAs for incident response.

1. Fan‑to‑Creator UX patterns (no “crypto hurdles”)

• Wallet‑light flows: embedded, non‑custodial smart accounts; one‑click signatures (EIP‑712) and gasless approvals; payroll‑like streaming receipts. (circle.com)
• Direct support modes: enable “fan‑powered” or user‑centric models by routing per‑fan contributions directly to the artist’s stream/split rather than pooling. (press.soundcloud.com)

1. Reporting and finance ops

• On‑chain receipts + off‑chain BI: every disbursement emits machine‑readable events with canonical IDs (ISRC/ISWC/IPI), reconciling to DSP statements and general ledger.
• Audit pack: cryptographic proofs, sanctions checks, and payout events packaged for quarterly audits and royalty statements.

Practical architecture (what we implement in 8–12 weeks)

• Ingestion
  • DDEX ERN 4.3 for releases/updates; MEAD/PIE for enrichment; DSRF for sales/usage; SURF for MLC exceptions. (ddex.net)
• Identity and keys
  • Rights graph mapping ISRC ←→ ISWC/IPI and party roles; resolver keeps “release‑specific” deltas explicit; continuous validation. (kb.ddex.net)
• Attestation
  • ETL to warehouse; Proof‑of‑SQL‑style ZK attestations produce compact proofs per period/asset; proof hash anchors on‑chain with references to statement IDs. (cloud.google.com)
• Payout orchestration
  • Net per asset → split contract → USDC distribution; for recurring flows (e.g., catalog advances), switch to streaming (Superfluid/Sablier) with configurable rates and cliffs. (docs.superfluid.org)
• Gas and user experience
  • USDC‑denominated fees via Paymaster; signature‑based pulls with EIP‑3009/Permit2; no “get ETH” steps for recipients. (circle.com)
• Cross‑chain liquidity
  • If you need Base for cost and Starknet for specific partners, CCTP V2 rebalances USDC natively—no wrapped fragments; programmable “Hooks” auto‑execute deposits post‑mint. (circle.com)
• Compliance guardrails
  • Pre‑send sanctions screening on recipient wallets; flagged events quarantined for review; audit logs preserved for SOC2 and financial audits. (chainalysis.com)

Concrete examples

• Example A: “Threshold‑proof payouts” for long‑tail tracks

  • Problem: Post‑April‑2024, tracks below 1,000 streams don’t earn on Spotify; creators still deserve a fan path. We enable “direct top‑up”: fans contribute $1–$5; funds stream to the artist wallet, visible in real time; minimum DSP thresholds become irrelevant to fan support. (artists.spotify.com)
  • Implementation: Split contract mints an NFT representing the artist’s revenue share; Superfluid stream starts at $0.001/sec; Circle Paymaster covers gas in USDC; KYC gating optional for higher tiers. (docs.superfluid.org)

• Example B: “Label‑publisher clean room” with ZK‑verified aggregates

  • Problem: You need to demonstrate that label remittances match usage across DSPs without handing over raw, fan‑level data.
  • Implementation: DDEX DSRF files load to BigQuery; a ZK prover attaches a correctness proof to the monthly aggregate per ISRC; smart contract verifies the proof hash before releasing USDC to the split. Finance downloads the audit pack for the month. (themlc.com)

• Example C: “Cross‑chain touring drops”

  • Problem: Tour‑based campaigns spin up short windows with high micro‑payout volume; you need elasticity and low fees.
  • Implementation: Fans pay on Base (low fees) while the catalog treasury sits on OP Mainnet; CCTP V2 moves USDC natively with “Hooks” to deposit straight into the label’s receivables contract; splits auto‑distribute to participants. Visa’s USDC settlement strengthens treasury’s comfort for rapid cash management. (circle.com)

Emerging best practices we apply now

• Treat DDEX as code: enforce ERN/MEAD/PIE/DSR schemas in CI; fail fast on invalid fields; annotate “release‑specific” metadata variances to avoid accidental overrides. (ddex.net)
• ZK proofs where they de‑risk audits: verify sums, not users. You keep fan privacy while giving finance cryptographic reconciliation against usage sources. (cloud.google.com)
• Default to L2s post‑Dencun: Architect for Base/OP/Arbitrum/Starknet fee profiles; sub‑cent transfers enable per‑fan micro‑support and micro‑royalties at scale. (l2fees.info)
• USDC‑native UX: Use EIP‑3009/Permit2 for signature‑only approvals; Circle Paymaster so creators never ask, “Where do I get ETH?” (circle.com)
• Sanctions controls in the hot path: pre‑send screening plus post‑send monitoring (KYT) to satisfy enterprise compliance and reduce reversal headaches. (chainalysis.com)
• Plan DDEX upgrades: ERN v3/4.0 and XML DSR deprecations are time‑boxed—budget the migration before support sunsets (Mar 1, 2025 for XML DSR; Mar 1, 2026 for ERN v3/4.0). (kb.ddex.net)

ROI and GTM metrics you can take to procurement

• Cycle time: from 60–90 days to T+1 settlement on verified usage; optional T+0 streaming for direct fan dollars. Based on L2 fee data, per‑payout network cost trends to <$0.01. Finance can model WACC savings on working capital released. (helpdesk.revelator.com)
• Disputes: ZK‑verified aggregates plus explicit metadata rules cut “where did the money go?” tickets; historical clients see double‑digit reductions in unmatched lines post‑DDEX hardening. (ddex.net)
• Creator NPS: real‑time receipts and transparent splits reduce support burden; fan‑powered options align dollars with fandom (less leakage to pooled models). (press.soundcloud.com)
• Compliance: pre‑send sanctions checks and immutable receipts satisfy internal audit and external examiners; provide SOC2 evidence and SLAs in your VRM portal. (chainalysis.com)

Why now? The rails are mature

• EIP‑4844 brought L2 fees down to cents/sub‑cents; Visa’s USDC settlement and Circle’s CCTP V2 standardize the treasury side. Streaming protocols (Superfluid, Sablier v2) are battle‑tested with audit trails and SDKs. The stack is ready for enterprise adoption—without asking artists to learn crypto. (coindesk.com)
