Overview

Writz Protocol’s economic sustainability depends on a well-designed fee model. This document defines all revenue streams, the protocol fee structure, treasury allocation, and the governance token strategy — informed by the 2025–2026 shift in DeFi toward real-yield tokenomics.

Industry Context: The Real-Yield Shift (2025–2026)

The DeFi industry has fundamentally changed its tokenomics approach:

Old model (2020–2023): Emit governance tokens as liquidity mining rewards. Users farm tokens, dump them, APYs collapse, protocol dies.

New model (2024–2026):

• Uniswap: 17% of swap fees auto-buy and burn UNI tokens
• Aave’s “Aave Will Win”: protocol revenue directly tied to AAVE token through buyback mechanism
• Compound, Curve: fee revenue distributed to stakers/veTokens

The paradigm: Governance tokens must be backed by real protocol revenue, not emissions. Writz will design tokenomics from day one around real cash flows.

Revenue Streams

Primary: Lending Spread (PrivateLend)

The difference between the borrow rate (what borrowers pay) and the supply rate (what lenders earn).

At 75% utilization (Uoptimal):
  Borrow rate: 8% APR
  Supply rate: 6.8% APR (= 8% × 75% × 85%)
  Protocol spread: 1.2% APR on borrowed amount

At $1M TVL with 75$750K borrowed): ~$9,000/year in spread revenue.

Secondary: SPV Verification API

Other Stellar protocols pay to use Writz’s Bitcoin SPV client.

Pricing model:

• Per-verification fee: $0.10–$0.50 per proof verification
• Monthly subscription: $500–$5,000/month for high-volume protocols

Early adopter pricing is aggressive — the goal is ecosystem adoption, not maximizing API revenue in Year 1.

Tertiary: Swap Fees (Dark Swap)

Basis points on BTC/USDC swaps. Target: 0.3% per swap (comparable to Uniswap v3).

At $10M monthly swap volume:$30,000/month in swap fees.

Quaternary: ZK Proof of Reserve SaaS (B2B)

Enterprise customers pay for private, verifiable BTC reserve attestations.

Pricing model:

• Starter: $500/month — up to 5 attestations
• Professional: $2,000/month — unlimited attestations, custom reporting
• Enterprise: $10,000+/month — SLA, dedicated support, compliance documentation

Target: 10 paying enterprise customers in Year 1 = $20,000–$100,000/year.

Liquidation Fees

2% of liquidated collateral value goes to the protocol.

At 10 liquidations/month averaging $20,000 each:$4,000/month.

Fee Distribution

All protocol revenue flows into a distribution contract that routes funds to:

100% of Protocol Revenue
├── 30% → Insurance Fund (on-chain safety reserve)
├── 30% → Token Buyback & Burn (reduces supply, supports token price)
├── 25% → Operations Treasury (salaries, infrastructure, audits)
└── 15% → Ecosystem Grants (developer grants, integrations)

Insurance Fund: Accumulates until it reaches 10% of TVL. After that, excess flows to buyback instead. This ensures the protocol can cover bad debt without relying on tokenomics.

Buyback & Burn: Protocol buys WRTZ tokens from the open market and burns them. This creates deflationary pressure tied directly to protocol usage — more borrowers = more revenue = more buybacks = less token supply.

---

Governance Token: WRTZ

Design principles

• Total supply: 100,000,000 WRTZ (fixed, no inflation)
• 100% backed by real protocol revenue (no liquidity mining emissions)
• Governance rights over protocol parameters
• Revenue sharing via buyback/burn (not direct dividends — cleaner tax treatment)

Distribution

Allocation	%	Amount	Vesting
Team	20%	20M	4 years, 1-year cliff
Investors (seed)	15%	15M	2 years, 6-month cliff
Ecosystem/grants	20%	20M	3 years, monthly release
Community/DAO treasury	25%	25M	Governed by DAO
Protocol-owned liquidity	10%	10M	Used to seed USDC pools
Public launch	10%	10M	IDO / fair launch

No pre-mine for team beyond the 20% with vesting. The community treasury (25%) is controlled by WRTZ governance from day one.

Token utility

1. Governance: Vote on protocol parameters (interest rate curves, collateral ratios, fee splits, new features)
2. Fee capture: Buyback/burn mechanism means holding WRTZ benefits from protocol growth
3. Staking for enhanced yields: WRTZ stakers receive 10% boost on USDC lending yields (creates demand for staking)
4. Liquidation priority: WRTZ stakers have first access to liquidation opportunities (creates demand from keeper operators)

When to launch the token

Not in Phase 1 or Phase 2. Token launches before product-market fit destroy communities and set unrealistic expectations.

Token launch criteria:

• $5M TVL sustained for 60+ days
• 500+ active users
• At least one completed external audit
• Clear governance use cases ready to deploy

Expected timeline: Q2–Q3 2027.

Financial Projections (Conservative)

Year 1 (2027, post-launch)

Revenue Stream	Monthly	Annual
Lending spread (@ $2M TVL, 75% util)	$1,500	$18,000
Dark Swap fees ($500K/month volume)	$1,500	$18,000
SPV API	$500	$6,000
Proof of Reserve (5 customers)	$5,000	$60,000
Liquidation fees	$1,000	$12,000
Total	$9,500/month	$114,000/year

Year 2 (2028)

Revenue Stream	Monthly	Annual
Lending spread (@ $20M TVL, 75% util)	$15,000	$180,000
Dark Swap fees ($5M/month volume)	$15,000	$180,000
SPV API	$5,000	$60,000
Proof of Reserve (25 customers)	$25,000	$300,000
Liquidation fees	$5,000	$60,000
Total	$65,000/month	$780,000/year

These are conservative estimates. At BTCfi’s current 28× annual TVL growth rate, the upside scenario significantly exceeds these numbers.

Key Decisions

Decision	Choice	Rationale
Token model	Real-yield, buyback/burn	2026 industry standard; no inflationary emissions
Token supply	100M fixed	Simple, no inflation
Token launch timing	Post $5M TVL	Product-market fit first
Protocol fee %	15% of interest spread	Higher than Aave (10%) due to ZK infrastructure costs
Insurance fund target	10% of TVL	Industry standard; covers typical bad debt scenarios
Revenue distribution	30/30/25/15	Balanced between safety, token health, operations, growth
