Transparency & proof of reserves

Proof of reserves

Live on-chain assets versus what we owe users, read straight from Base and the ledger.

Nothing owed

Assets — USDC we hold on chain$0.00

Treasury $0.00
Unswept deposit addresses $0.00

Liabilities — what users can take out$0.00

User balances $0.00
Open market escrow $0.00

Operator equity (fees + house capital)$0.00

Surplus over liabilities+$0.00

Assets are the USDC actually sitting in our treasury and in user deposit addresses on Base Sepolia, read live from the chain. Liabilities are everything we owe: spendable balances plus stakes escrowed in open markets. If assets ≥ liabilities, every user could withdraw at once. Fees and house capital are ours, not yours — they sit on top of the money owed to users.

Latest signed snapshot

No snapshot has been published yet. Snapshots run daily (and on demand from the admin console) — each one signs a Merkle root over every user balance.

Ledger integrity

Every movement of money is one append-only, hash-chained double-entry. This check re-hashes the newest entries and replays every balance from the full history.

Chain intact

Entries re-hashed: 0(the whole chain)
Head entry: #0
Head hash: 0x0000000000…0000000000
Checked: Sep 12, 09:26 UTC· re-runs at most once a minute

Hash chain intact — each entry hashes its predecessor, so no row can be edited or removed without breaking every later hash.
Σ balances = 0 and every cached balance matches the replay.

Double-entry means money is never created or destroyed: every entry moves an amount from one account to another, so all balances sum to zero (the outside world, external:…, goes negative as deposits come in). The hash chain makes the history tamper-evident: change one old row and the head hash above stops matching. Re-hashing is capped at the newest 500 entries so this public page can't be used to load the database — editing an older row still shows up instantly, because every later hash (and the head hash above) would have to change with it, and the balance replay above covers the entire table either way.

Signed resolutions

Every settled market carries an EIP-712 attestation over its outcome and evidence. Verify any of them in your browser.

No markets have been finalized yet

When the resolver agent proposes an outcome and an admin finalizes it, the signed attestation shows up here.

Operator capital seeding opening lines

The fee is 5% of the whole pool, skimmed once at settlement and capped at the losing side so a winning bet always gets at least its stake back. Voided markets and markets with nobody on the winning side are refunded in full with no fee. Because the cut is the same whichever way a market resolves, our revenue never depends on the outcome we finalize.

Public ledger

Every entry ever written, pseudonymised. Newest first.

No entries yet

The ledger is empty — the first deposit or house-funded market will start the chain.

User ids are replaced with the first bytes of their hash, so you can follow the money without learning who anyone is. Each row's hash commits to its contents and the previous row's hash — that's the chain verified above.
