The Challenge

The Layer 2
Limitations

Ethereum L2s face fundamental tradeoffs. Metal L2 needs a path that prioritizes sovereignty, speed, and banking compliance.

0 days
Withdrawal Delay

Optimistic rollups require a 7-day challenge period to withdraw to Ethereum

0 min
True Finality

L2 transactions aren't final until settled on Ethereum L1

Challenges for Banking & Compliance Use Cases

Frequent upstream upgrades require coordinated node updates across all partners
Exchange partners must track and test each upgrade — adds operational burden
Centralized sequencer is a single point of failure for transaction ordering
Data availability costs on Ethereum are variable and can spike unpredictably
No custom gas token — cannot use MTL or XMD for gas natively
Limited sovereignty over upgrade cadence and chain parameters
Revenue sharing obligations reduce protocol sustainability
7-day delay makes the chain less attractive for exchange listings vs instant-finality alternatives
The Opportunity

The Stablecoin
Moment

$310B market. $33T annual volume. The stablecoin chain race is on.

Stablecoin Market ($310B)

Top Chains by TVL

XMD

Metal Dollar (XMD)

Current: $830K market cap — 836K supply

Our edge: Basket-backed (USDC + PYUSD + USDP + RLUSD). 1,000+ Credit Union Network. Compliance-ready contracts (freeze/seize/pause). Metal API for developer integration. No competitor has this banking distribution.

The Plan

Three Tracks,
One Vision

Three parallel workstreams. Ship fast, build right.

TRACK 01

XMD on Ethereum

1-2 Months
  • Deploy XMD contracts on mainnet
  • Curve metapool (XMD/USDC)
  • Uniswap v3 concentrated liquidity
  • Morpho Blue lending market
  • Aave v3 listing proposal

Ethereum has $164.68B in stablecoin supply — it's where stablecoins get used.

TRACK 02

Metal Blockchain Subnet

3-6 Months
  • EVM subnet with MTL as gas token
  • Sub-second finality (~0.5s)
  • Fork Teleporter for bridging
  • Future: add XMD gas support
  • Compliance precompiles

Full sovereignty. No forced forks. MTL gas = governance token utility.

TRACK 03

ZK State Proofs

6-12 Months
  • Succinct SP1 ZK integration
  • Verifiers on every XMD chain
  • Cryptographic supply transparency
  • ZK-verified cross-chain transfers

Every chain mathematically verifies XMD supply. No bridge trust. Novel positioning.

Gas TokenETHMTL (future: XMD)

XMD Multi-Chain Architecture

Independent treasuries per chain — no bridge dependency for backing. Same model as Circle deploys USDC.

Metal Subnet

Primary
  • XMD Treasury with USDC/PYUSD/USDP/RLUSD reserves
  • MTL as native gas token
  • DEX liquidity pools
  • Potential LOAN Protocol integration

Ethereum

Mainnet
  • Independent XMD Treasury
  • Own reserves on Ethereum
  • Curve + Uniswap pools
  • Morpho + Aave lending

XPR Network

Legacy
  • Metal X bridge + xTokens
  • LOAN Protocol (existing)
  • Zero gas fees
  • Metal X DEX trading

Why Independent Treasuries (Not OFT Bridge)?

Independent Treasuries (Recommended)

  • Each chain backed by real reserves on that chain
  • No bridge = no bridge risk
  • If one chain is compromised, others unaffected
  • Same model as Circle deploys USDC

OFT Bridge (Not Recommended for Backing)

  • Bridge = single point of failure
  • LayerZero DVN trust dependency
  • $2.8B lost to bridge hacks historically
  • Use bridges for transfers only, not backing

Exchange Migration Plan

Pitch to exchanges: “Same EVM RPC you already know. One stable node. No more forced forks.”

Growth Strategy

What Actually
Drives Adoption

Stablecoins grow through distribution, yield, and captive use cases. Not DEX pairs.

What Actually Grows Stablecoins (Data-Backed)

#1Distribution

USDT grew via exchanges. PYUSD via PayPal (400M users). USDC via Coinbase.

Metal has 1,000+ Credit Union Network

#2Governance Utility

MKR governs DAI. stkAAVE gets GHO discounts. Token utility drives demand.

MTL holders get fee discounts + basket votes

#3Captive Use Case

GHO in Aave. crvUSD in Curve. Built-in demand loop.

MTL as gas token + potential LOAN Protocol integration

#4Payments

USDT on Tron: $600B+/month in remittances. Real utility, not speculation.

MTL AS GAS TOKEN

MTL

Powers Every Transaction

100%

of subnet transactions require MTL

  • MTL is the native gas token on the Metal Blockchain subnet
  • Every swap, transfer, mint, and contract call requires MTL
  • Gas fees flow to validators and protocol treasury

“Every transaction on the new Metal L2 requires MTL. Non-optional, structural demand.”

MTL GOVERNANCE

Governs XMD

Basket Votes + Fee Discounts

≤$5

XMD mint/redeem fee — MTL holders pay less

  • MTL holders vote on XMD basket composition via gov.xprnetwork.org
  • Mint/redeem fees (% based, max $5) — MTL stakers get discounts
  • MTL governs subnet parameters, incentive allocation, protocol upgrades

“Like stkAAVE gets discounted GHO rates. Hold MTL, pay less.”

DISTRIBUTION MOAT

1,000+

Credit Union Network

130M+

US credit union members — potential reach

  • US-Mexico remittances: $63B/year (1% capture = $630M)
  • CU-to-CU settlement: currently 1-3 days ACH → instant with XMD
  • Credit union stablecoin pilots launching on Metal

“No other stablecoin has banking distribution like this.”

The Breakthrough

The Credit Union
DeFi On-Ramp

Banks fear deposit flight from stablecoins. This model solves it. The deposit never leaves the credit union.

Zero Deposit Flight

When a customer buys USDC on Coinbase, the deposit leaves the bank. The bank loses the deposit, the lending power, and the relationship.

With Metal Dollar, the deposit stays at the credit union. The CU stablecoin is just a digital receipt. The CU can still lend against it. The customer gets DeFi access. Everyone wins.

USDC Model

Customer buys USDC → deposit leaves bank → bank loses

XMD Model

Customer mints CU coin → deposit stays → CU wins too

🏦

Customer deposits at CU

Deposit stays

Fiat stays in the credit union. No deposit flight.

🪙

CU mints its stablecoin

XMD → CU Stablecoin → Fiat at credit union. Full circle.

Three Paths to DeFi — All Via XMD

XPR Network + Metal X

Zero gas fees. xToken trading. LOAN Protocol lending. Ideal for simple, regulated access.

Metal L2 + Velodrome

EVM DeFi on Metal L2. XMD pairs on Velodrome. Ionic lending. Low fees, fast finality.

Ethereum Mainnet

Deepest liquidity. Curve, Uniswap, Aave, Morpho. For users who want maximum DeFi access.

All paths start and end at the credit union. On/off-ramp always goes through the bank.

The CU Pitch

For the Credit Union

  • Keep customer deposits — no flight to Coinbase/USDC
  • Continue lending against deposits (fractional reserve)
  • Earn mint/redeem fees on CU stablecoin
  • Modern offering for younger members

For the Member

  • Access DeFi without leaving their CU
  • Trade crypto pairs via XMD (XDOGE, XBTC, etc.)
  • Access DeFi protocols on Metal L2
  • Always off-ramp back through their CU

For Metal DAO

  • Every CU stablecoin → XMD basket = XMD supply growth
  • MTL holders govern which CU coins enter basket
  • Mint/redeem fees generate protocol revenue
  • 1,000+ Credit Union Network = massive distribution moat

xTokens: Narrative Play

Secondary Strategy

xTokens (XDOGE, XXRP, etc.) paired against XMD add DEX activity and build brand awareness. However, data shows wrapped token hubs have historically underperformed — Osmosis collapsed 95% when emissions ended. Position as brand awareness play, not primary growth driver.

Scenario: At $50M supply — Revenue $3-4M/yr vs Costs $155-420K/yr

High confidence: Treasury yield math is simple (supply x rate). Low confidence: Gas revenue depends on transaction volume which is unpredictable. Break-even is achievable at ~$5-10M supply from yield alone.

Legal & Compliance

Regulatory
Position

Designed for GENIUS Act compliance from Day 1. No securities classification risk.

Why XMD Is Compliant

GENIUS Act: 1:1 backing

XMD basket (USDC + PYUSD + USDP + RLUSD) — all already compliant

GENIUS Act: No yield to holders

XMD does NOT pay yield. Revenue stays in protocol treasury. Fees, not interest.

SEC: Not a security

No yield = no "expectation of profit" = no Howey. Payment stablecoin only.

Compliance tooling

FUNDS_PROTECTION_ROLE: freeze/seize/pause built into smart contracts

NCUA compatible

CU stablecoins via subsidiaries (CUSOs). Deposit stays at CU.

What We Deliberately Avoid

Yield-bearing stablecoin (sXMD)

GENIUS Act prohibits issuers paying yield. SEC would classify as security. Only legal path is SEC registration (YLDS model) — too heavy.

Passing CU loan yield to holders

Would trigger money market fund classification + violate GENIUS Act interest prohibition.

Algorithmic/undercollateralized design

XMD is 1:1 basket-backed by regulated stablecoins. No algo risk.

Unregistered offering in EU

MiCA deadline July 1, 2026. Evaluate EU deployment separately if needed.

The Revenue Model Is Legal Because...

Mint/Redeem Fees

Like ATM fees or wire transfer fees. Service charge, not interest.

Treasury Yield (Kept by Protocol)

Exactly what Circle does — earns $1.68B/yr on USDC reserves. Legal, proven.

DeFi Lending (Potential)

Users could lend XMD for yield via protocols like LOAN. User decision, not issuer paying.
