Yosoku appears in the launch corpus as a fully on-chain Solana central-limit-order-book prediction protocol tied to scalar outcomes. The chain field reads Solana; readers should treat that as classification data pending confirmation in current documentation. The venue entered this dataset with a live status hint rather than a continuously monitored uptime claim. The retained research status reads "live": Official documentation specifies live Solana order-book trading, fees, market creation and redemption.

Confirmation belongs at https://yosoku.fun/, including whether Yosoku still offers the described product. A valid HTTPS response is not equivalent to verified trading availability. The claims below remain limited to what the cited material supports.

Yosoku should be researched from its literal fact set—scalar outcomes, n/a mechanics, and Solana. These labels are useful for discovery while remaining insufficient for financial, legal, or security conclusions. Later primary evidence can update these fields without changing the underlying standard.

Yosoku's retained sources describe regional or eligibility boundaries, but readers should still check the current terms before access. Research summary: No geographic restrictions are stated in the reviewed official docs.

Because Yosoku is marked live, verify what that label currently means: a public interface, limited beta, waitlist, archive, or full execution may each produce different user expectations. KYC summary: No KYC requirement is stated; any supported Solana wallet can connect.

The mechanics snapshot for Yosoku lists n/a, serving markets described as scalar. A label such as AMM, CLOB, or sportsbook is too broad to determine actual fills or payouts.

Yosoku's market title is not enough for due diligence. Read definitions, edge cases, postponement language, resolver authority, and appeal timing before taking a position. Settlement and resolution summary: Markets use UMA bonded proposals with a 24-hour dispute window or majority vote by designated wallets. Unresolvable markets can settle 50/50; winning shares redeem after finalization.

The research record contains concrete cost information for Yosoku, without assuming that one rate applies to every product or jurisdiction. Retained fee evidence: 1.25% of taker trade value: 0.75% protocol and 0.50% creator. An optional 0.25% referral share comes from the protocol fee. Solana network fees are paid in SOL.

Some custody evidence is documented for Yosoku; that does not remove smart-contract, counterparty, signer, bridge, or account-recovery risk. Retained custody evidence: Non-custodial; USDC, shares and orders are held in program-owned accounts and users can interact directly with the open-source program.

Yosoku should be approached as a risk-bearing venue, not a source of guaranteed probabilities. Its live hint can become stale and must be reconciled with current official notices. Documented limitations include: Wallet-vote markets depend on designated voters., UMA disputes require a substantial bond., and On-chain order books can hit per-side capacity limits..
