FAQ
Answer common beginner, intermediate, and advanced Quovra questions.
FAQ
Beginner
What is Quovra?
Quovra is a Solana devnet settlement kernel for prediction markets. It releases escrow only after a signed TxLINE sports-data proof verifies on-chain.
Is this real-money wagering?
No. The current deployment uses devnet and test USDC.
Do I need a wallet?
You need a Solana wallet for deposits and claims. You do not need a wallet to read markets, receipts, docs, or explorer links.
What does YES mean?
YES means the stored predicate returns true. For example, "Will Spain score in the final?" resolves YES if the TxLINE proof validates that Spain scored.
Intermediate
Why does Quovra use pull payments?
Pull payments keep settlement cheap and safe. The proof-verification transaction resolves the market. Each winner claims separately.
Can anyone settle a market?
Yes. Anyone can submit a valid TxLINE proof. Invalid proofs revert.
What happens if TxLINE proof is unavailable?
The market stays unresolved until a valid proof is available and submitted.
What happens if a user deposits after kickoff?
The program rejects deposits after close_ts with MarketClosed.
Advanced
What prevents a fake oracle program?
The settle account constraints only accept known txoracle program IDs.
What prevents a proof for another match?
Quovra checks the proof fixture id against the stored fixture_id.
What prevents a proof for another stat?
Quovra checks the proof stat key against the stored stat_key.
What changes for mainnet?
Mainnet requires a separate deployment review, legal/compliance review, stronger faucet replacement, production RPC, monitoring, incident response, and possibly multi-provider proof quorum.
