Research: Tokenomics & Fee Model

Author: Research Date: 2026-06-22 Status: Complete

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

1M TVL with 75% utilization (

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

Scope status: This is a problem-and-hypothesis exploration, not a committed design. No contract, governance mechanism, or legal analysis of WRTZ’s status as a security in target jurisdictions exists today. Token launch is explicitly gated on post-$5M TVL (see “When to launch the token” below), so there is no urgency to finalize this - treat the distribution table and utility design as directional, not final, until closer to that milestone and until legal counsel has reviewed the security-classification question.

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

Governance: Vote on protocol parameters (interest rate curves, collateral ratios, fee splits, new features)
Fee capture: Buyback/burn mechanism means holding WRTZ benefits from protocol growth
Staking for enhanced yields: WRTZ stakers receive 10% boost on USDC lending yields (creates demand for staking)
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 (`PROTOCOL_FEE_BP = 1_500` in contract)	Higher than Aave (10%) due to ZK infrastructure costs
Mainnet bootstrap fee waiver	0% protocol fee for the first 90 days after mainnet launch, per `docs/roadmap/phases.md`	Bootstrap incentive to attract early liquidity; the 15% fee is a contract constant, so this waiver is a launch-time parameter change, not yet implemented in `rates.rs` - flag as an explicit pre-mainnet task, not an assumed feature
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

Insurance Fund Ramp

The

5K launch seed (`docs/research/security-audit-strategy.md` pre-mainnet checklist) is exactly 10% of the

50K launch TVL cap, so it starts on-target. As the TVL cap is raised, the fund needs to keep pace:

TVL cap	10% target	Funding source
$50K (launch)	$5K	Seeded directly at launch
$250K (post 30-day clean operation)	$25K	Must accrue from protocol fee revenue (30% slice) between launch and the cap raise
$5M+ (Phase 3 scale)	$500K+	Ongoing accrual from protocol fee revenue

Open gap: the fund is meant to grow from the 30% “safety” slice of protocol fee revenue, but the protocol fee is 0% for the first 90 days (bootstrap waiver, see the row above). That means the fund cannot accrue past its initial

5K seed during the exact window when TVL is scaling from

50K toward $250K, unless a separate top-up is planned. This needs an explicit answer before the 30-day TVL cap raise is exercised - either delay the cap raise until the fund has organically caught up, or fund the gap from another source.
