Sovereignty Roadmap
From Polygon to UC Chain in 4 Phases

UC starts on a proven chain (Polygon) for fast, cheap launch. UC migrates to its own blockchain when ready. By 2030, 269 country chapters run validator nodes — one per country and region.

01
LIVE NOW

UC Coin on Polygon

Stage 1 LIVE since April 2026. ERC-20 standard. 33B UC supply distributed to 4 wallets. Contract verified, audited, public.

02
Phase 2

UC Chain Testnet

UC's own blockchain begins testing. Built on OP Stack (Ethereum Layer 2). Code published on GitHub. First validators recruited from UC partner countries.

2027

03
Phase 3

UC Chain Mainnet

UC Chain launches. UC Coin migrates from Polygon (1:1 token swap). Holders keep balance, just new sovereign home. Bridge runs both chains in parallel during transition.

2028

Phase 4

269 Country Validators

Each country chapter runs a UC Chain validator node. UC-CEIB Bank operational. Treasury moves from Dutch UC investment company to UC Bank. Full sovereignty achieved.

2029-2030

Open Source Principles
Why UC is Different

Most crypto projects are private code controlled by a company. UC is the opposite — like Bitcoin, like Linux, like Wikipedia. Built in the open, owned by the community, accountable to math.

🔗

Anyone Can Audit

UC code is public on GitHub. MIT-licensed. Universities, security firms, governments can read every line. No hidden mints, no backdoors, no surprises. The math does not lie.

🛡

Anyone Can Run Validator

Once UC Chain launches, anyone with a server can become a validator. Universities, NGOs, country chapters, individual members. Earn UC Coin for securing the network. No permission needed.

🌏

Cannot Be Shut Down

By 2030, 269 country validators run UC Chain. To shut down UC, every government on Earth must agree — impossible. UC's voice is permanent.

Technology Stack
All Open Source. All Free.

UC Chain is built on proven open-source frameworks used by Polygon, Avalanche, Coinbase Base, and Optimism. Zero proprietary dependencies. Zero vendor lock-in.

How to Verify UC Coin

Anyone can verify that UC Coin matches what UC says it does. Here's how, in 4 steps. No special permission, no NDA, no fee.

1

Read the Contract

Visit PolygonScan and click "Contract" tab. The full Solidity source code matches the deployed bytecode. OpenZeppelin imports are publicly verifiable.

2

Verify the Distribution

Click "Holders" tab on PolygonScan. See all 4 wallets receiving 33B UC at deployment: Airdrop, Liquidity, Treasury, Team. Every transfer permanent and public.

3

Check the Locks

Team wallet (10%, 3.3B UC) cannot move until 27 April 2028. Lock enforced by smart contract logic, not promise. Try to move — transaction reverts.

4

Watch the Mint Cap

Owner can only mint up to 5% of supply per year, with 365-day cooldown. Every mint event logged on-chain with timestamp. No surprise inflation possible.

The UC Promise

Open by design. Sovereign by 2030.

UC Coin is not a company token. It is the blockchain of humanity's cultures. The code is public. The path is locked. The future is in the hands of every culture, every country, every member.
