Glossary / words on the report

What we mean when we say it

Short definitions for the fields VEIL Scan prints. For the scoring contract see Methodology. For the cryptography contrast see Learn.

Ledger

  • Signature

    The transaction id on Solana. Public, permanent, and what explorers index. VEIL Scan’s window is the last 100 of these for an address.

  • Slot

    A short time window in which a leader can produce a block. Used as a locator, not as identity.

  • Block time

    Unix timestamp the cluster associated with the block. Timing charts here use UTC hours from this field.

  • Fee payer

    Account zero in the transaction, which pays the fee. Usually the wallet that signed and submitted. Stronger than a receive.

  • Account keys

    Every account the transaction loaded — signers, writables, and lookup-table loads. The public cast list.

  • Program id

    The on-chain program that executed. Swaps, markets, bridges, and memo programs become a behavioral fingerprint when one address is reused.

  • CPI / inner instruction

    A program calling another program. jsonParsed metadata still lists those calls, so a router does not hide the AMM underneath.

  • Lamports

    1 SOL = 1,000,000,000 lamports. Balance changes in the report are computed from pre/post lamport arrays.

  • Memo programs

    MemoSq4gq… and Memo1Uhk… store UTF-8 notes on-chain. Invoices, names, and ids leak here more than anywhere else.

  • Program logs

    msg!() and similar output replicated by RPC with the transaction. Not a private logger. Emails and URLs that appear here are public.

The report

  • Exposure score

    A 0–100 heuristic from signature volume, counterparties, memos, apps, logs, and timing. A reading aid. See Methodology.

  • Finding

    A titled claim with summary, detail, severity, audience, and optional signature evidence.

  • Transfer map

    A picture of parsed value links. A line is interaction, not common ownership. Caps at 16 counterparties visually.

  • Counterparty

    Another public key that sent to, received from, or appeared as a token-account owner relative to the scanned address.

  • Recognized app

    A program id in VEIL Scan’s catalog (DEX, NFT, lending, bridge, and so on), excluding boring system/token traffic for fingerprinting.

  • Debug leak

    A memo, application-shaped log, or raw instruction-data excerpt aimed at builders, with a concrete recommendation.

  • Sample / demo report

    A fixture at /scan/demo that does not hit RPC. Use it to inspect layout when public endpoints are rate-limited.

  • jsonParsed

    RPC encoding that decodes common instruction layouts (system transfer, SPL, memo) into JSON instead of leaving opaque bytes.

Zero-knowledge contrast

  • Transparent transfer

    Sender, recipient, and amount are visible on the ledger. Typical Solana SOL/SPL moves look like this. Transparent ZEC does too.

  • Shielded transfer

    A payment whose value and parties are hidden in a proof the network can still verify. Zcash designed this for ZEC. VEIL Scan does not perform it.

  • Zero-knowledge proof

    A way to show a statement is true without revealing the witnesses. In a shielded payment: notes are valid, values balance, the spender had the right.

  • Viewing key

    In Zcash, a key that can disclose incoming (and sometimes outgoing) shielded activity to an auditor the owner chooses. Selective disclosure, not a global backdoor.

  • Token-2022 confidential transfer

    An optional Solana token extension. Not default, not Zcash, not what most wallets do. VEIL Scan reports RPC output, not guessed cleartext.
