Verify it onchain

MySphere's whole promise is that the money is real, not a number in our database. This page is the how-to: take any claim the app makes and check it yourself in a public block explorer, with no help from us.

What it does

Most money events in MySphere carry a transaction hash you can open in a block explorer. On Solana the transaction itself is the record: a post's receipt, its Proof of Bags balance, a SOL tip and a paid reply are all read on explorer.solana.com, and SOL tips are not recorded by MySphere at all. Some things are onchain contracts you can read directly (the Ask escrow, the Startpad launchpad and its B20 tokens). One thing, the Morpho curator record, is not a transaction at all. It's a dated reading of public Morpho data, and this page says so plainly so you don't go hunting for a hash that was never minted.

How to use it

1. Copy the hash or address the app shows you (tip receipt, Ask payout, token page).
2. Pick the right explorer for the network it lives on (table below).
3. For a tip, paste the id into the explorer's search box, not a raw /tx/ URL. Base Pay tips record a userOp id (an ERC-4337 order), which is 32 bytes just like a transaction hash but isn't one. The search box resolves both; a hard /tx/ link only works for real transactions.
4. For an Ask or a Startpad token, open the contract's address and use the "Read Contract" / "Events" tabs to see the numbers for yourself.

How it flows

The math

An Ask escrow holds a budget in USDC. When unused budget returns to the author (expired or unfilled), the contract takes an immutable fee. You can reproduce the split from the contract's feeBps:

$\text{fee} = \left\lfloor \frac{\text{budget} \times \text{feeBps}}{10000} \right\rfloor, \qquad \text{toAuthor} = \text{budget} - \text{fee}$

The fee rounds down, so the author's share is always the exact remainder. The two add back to the budget to the cent. Payouts to answerers are the per-answer stake times the seats awarded; nothing is ever paid without a SeatAwarded log carrying the answer's reference.

Check it onchain

• For the Ask escrow on Base (USDC), open the escrow address on basescan.org, call escrowFor(author, askId) to see the locked budget, seats and deadline, and claimable(account) to see a balance waiting to be collected. FEE_RECIPIENT() and the fee are immutable. It's also deployed on Base Sepolia (chainId 84532) for testing.
• The Startpad launchpad addresses are in the table above, and the full per-network set (vault, hook, token factory) sits in the footer of /startpad with explorer links. Startpad runs on Base mainnet (the default), Robinhood Chain and Arc mainnet; testnets are hidden from its switch. Read a B20 token to confirm its fixed supply and that it exposes no owner/admin functions.
• For Solana, the exact memo formats and what each one proves are on Solana: bags, tips & replies. MySphere deploys no program on Solana: posts and replies use Solana's Memo Program (v2 MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr, Proof of Bags v1 Memo1UhkJRfHyvLMcVucJwxXeuD728EqVDDwQDxFMNo) and tips use plain System Program transfers.
• There's one honest limit. The Morpho curator record is verifiable only in the sense that you can read the same public Morpho data we did. It isn't a MySphere transaction, so treat its timestamp as a dated snapshot, not a hash.
