A signed read of any address, in two minutes, for $29.
Name one public address. Pay $29 in USDC on Base. The instant the payment confirms, you get a machine-signed, point-in-time statement of what the address held on-chain as of a specific block: the live supply, decimals, and symbol, signed so it cannot be edited after the fact. No email, no wait, no human in the loop. Anyone you forward it to can verify it in about three lines.
$29 flat, one time, self-serve in USDC on Base. It is a factual read of public on-chain bytes at a block height. It does not assert who controls the address, and it is not a solvency opinion, a rating, or an audit.
Paste any Base or Ethereum token address. Preview the free read, then pay $29 to get it signed and archived. It signs public bytes only: supply, decimals, and symbol at a block.
Our guarantee. If the read we deliver does not cryptographically verify against the named signing key, we refund the fee or re-run it, your call. That is the one promise attestation can make and keep. It is not a promise about the figures, about who controls the address, or about any outcome; a faithful read of an empty address will faithfully show it is empty. Delivery is instant on this page; if a payment goes through and the signed read does not render, write to kerne.systems@protonmail.com with the transaction hash and we make it right.
What your $29 buys
The facts themselves are free: the same live supply, decimals, and symbol are readable by anyone, including on our own free tool. What you pay for is the part a screenshot cannot give you: a named signature over those exact bytes at a specific block, so the read cannot be edited after the fact and anyone you forward it to can confirm it independently.
- A signed JSON statement of the token supply, decimals, and symbol at a specific block, on Base or Ethereum.
- An EIP-191 signature from a named Kerne key, plus the attestation hash it signs, so the read cannot be altered after the fact.
- The exact commands to reproduce and check it yourself: recover the signer and rebind the numbers with cast, ethers, Python, or curl.
- Delivered on this page in about two minutes and downloadable as read.json. No email, no account, no waiting on a human.
- Bound to your payment transaction and single-use, so the artifact is provably the one you paid for.
- Covered by the guarantee: if it does not verify against the named key, we refund the fee or re-run it.

cast wallet verify --address $SIGNER $HASH $SIGExample values shown. Your read is generated live against the block you name, and the signature is produced only after your payment verifies on-chain. The signer address above is the real, published instant-read key.
How it works
Three steps, no account, no call. The read you sign is the same read the free tool runs; paying just makes it signed, archived, and re-derivable by anyone.
Paste any Base or Ethereum token address and preview the free read, so you see exactly what you are about to sign: the live on-chain supply, decimals, and symbol at the current block.
One on-chain payment, straight to the founder-controlled Kerne treasury. The transaction hash is the receipt. Connect a wallet to pay in one click, or pay from any wallet or exchange.
The instant the payment confirms, the read is re-verified on-chain, signed with a named EIP-191 key, and rendered here to download: the signed statement, the signature, and the three lines anyone can use to check it.
What this is, stated plainly
This is attestation and objective-data tooling. It reads and signs what the public chain shows for one address as of a specific block: the ERC-20 supply, decimals, and symbol, signed so the read cannot be edited after the fact. It is a factual read of public on-chain bytes at a block height. It does not assert who controls the address, and it is not a solvency opinion, a rating, an audit, or financial, legal, or accounting advice.
We read public on-chain data only. We do not value or vouch for anything the address may hold off-chain, and we do not infer what the supply is meant to back. We report what is there, sign it, and mark the edges of what a single read can prove. That honesty is the product: a bounded read you can verify is worth more than a confident number you cannot. Kerne's own reserves are attested separately and freely at kerne.fi/api/por/signed; the paid signer never signs a read of a Kerne address.
Free below, human-reviewed above
This is the fastest, cheapest signed artifact Kerne sells. Below it, the same read is free and unsigned; above it, a human reviews the read and its boundary. All of it is built on the same signing stack you can verify yourself.
The same live read, free and unsigned, for any token. Paste an address and see what you can verify yourself versus what needs an attestor.
A human-reviewed signed read of one address, with its balances and the boundary of what a single address can prove, delivered by hand.
An independent signed read of a counterparty you are exposed to: the token and the public addresses that back it, on one chain.
Kerne is infrastructure and a service provider, not an auditor, a rating agency, a custodian, or an investment adviser. An instant signed read is attestation and objective-data tooling: it reads and signs public on-chain data for one address as of a block. It does not assert who controls the address, does not value or vouch for off-chain holdings, and is not an audit, a solvency or credit opinion, a recommendation, or any form of investment, legal, tax, or accounting advice. The read is signed by a dedicated Kerne key (0x84949170e0ad0f9bd8686a4aa4922c10f5fdc4ea); this tooling stands on cryptography and public data you verify independently, not on our posture. Kerne is early: it has one completed external audit, published in full on July 31, 2026, and its deployed vault runs earlier bytecode than the reviewed commit, disclosed at kerne.fi/dataroom. The read fee is $29 fixed, earned on delivery.
