🔒 Solum — Immutable Substrate

Solum is the on-chain substrate of Zipvilization.

It is not a governance token. It is not an experimental mechanic. It is not a promise of yield.

Solum defines what is possible and what is not inside the system.

If a rule is not present in the contract, it does not exist.

🧱 What Solum Is

At the contract level, Solum is an ERC-20 token with fixed supply and immutable rules.

At the Zipvilization level, Solum represents territory:

  • 1 Solum = 1 square meter of land
  • Total world size: 100 trillion m² (100T Solum)
  • No minting. No inflation. No expansion.

Solum is the soil upon which the civilization emerges.

🛡️ What Solum Protects

Solum is designed to protect the system during its most fragile phases.

1. Fair Access

  • Max Transaction (MAX_TX)
    Prevents instant dominance via single large movements.

  • Max Wallet (dynamic)
    Starts constrained and grows over time, allowing:

    • early protection
    • long-term expansion

These limits are not permanent walls — they are temporal safeguards.

2. Structural Friction (Taxes)

Solum applies immutable taxes depending on transaction type:

  • Buy
  • Sell
  • Transfer

These taxes are not arbitrary.

They introduce friction, which is essential for:

  • discouraging extractive behavior
  • slowing destructive velocity
  • funding long-term development

At the contract level, taxes route value into:

  • burn
  • liquidity
  • reflection
  • treasury

Their meaning inside Zipvilization is described separately.

3. Supply Integrity

  • Fixed total supply
  • Real burn (supply is permanently reduced)
  • No administrative minting
  • No emergency inflation

Solum’s scarcity is not narrative — it is enforced.

4. Launch Discipline

Before trading is enabled:

  • Only explicitly exempt addresses can move tokens
  • No silent accumulation
  • No pre-launch chaos

The moment trading is enabled marks Day 0 of the system.

🌍 Solum Inside Zipvilization

Solum is not just a token.

Inside Zipvilization, the same mechanics represent:

  • territory
  • geography
  • time
  • evolution
  • irreversible change

➡️ Solum Translation (Zipvilization Context)
docs/zipvilization/SOLUM_TRANSLATION.md

This document explains:

  • why burn becomes forests, rivers, and lakes
  • why transfer taxes represent relocation cost
  • why treasury growth enables evolution
  • why holders are also colonists

🧭 Final Note

Solum does not try to optimize outcomes.

It defines constraints.

Everything that emerges later — tools, worlds, visuals — must operate within these limits, not around them.

Solum is not flexible by design.

It is reliable.
