​
The network

Stellar is a layer-1 blockchain optimized for payments and asset issuance. It was built from the ground up for financial applications — fast settlement, near-zero fees, and native support for assets like USDC make it a natural fit for a fundraising protocol.

​
Stablecoins on Stellar

Lumena uses USDC as its contribution currency. Stellar hosts native USDC issued directly by Circle — the same entity that issues USDC on Ethereum and Base. This means dollar-stable contributions with no bridge risk and no wrapped asset complexity. To get USDC on Stellar, you can:
  • Receive it from a Stellar-native exchange
  • Use the Bridge action in your Lumena wallet to move USDC from another chain
  • Purchase it via a centralized exchange that supports Stellar network withdrawals (Binance, Kraken, and others)

​
Smart Contrats on Stellar

Each Lumena raise is an independent smart contract deployed on Stellar using the Soroban smart contract runtime. There is no central Lumena contract that holds all funds — each raise is isolated. A bug or exploit in one raise contract cannot affect any other.

​
The raise contract

The raise contract enforces three properties:
  • Escrow. USDC is held by the contract, not by the deployer. The deployer cannot withdraw mid-raise under any circumstances.
  • Success release. When contributions reach the target before the deadline, USDC is released to the deployer address automatically.
  • Failure refund. If the deadline passes without the target being met, every contributor can claim back their exact contribution from the contract.

​
The governance contract

The governance contract manages futarchy markets. It accepts proposals, opens and closes trading markets, reads final market prices at expiry, executes on-chain actions for passing proposals, and routes protocol fee revenue to the treasury.

​
Audits & verification

Every raise contract address is publicly visible on its project page and verifiable on Stellar Expert. Contract source code is open. Audit reports will be linked here as they are completed.
You can independently verify any raise contract’s USDC balance, contribution history, and status on Stellar Expert at any time — without trusting the Lumena frontend.
