  "name": "DN TxFlow documentation review",
  "version": "1.0.0",
  "reviewedAt": "2026-10-15",
  "reviewDue": "2026-10-29",
  "method": "AI-assisted public-document desk review; no funded account, trading, withdrawal, benchmark or security testing.",
  "records": [
    {
      "id": "txflow-01",
      "area": "Architecture",
      "source": "https://txflow.com/",
      "finding": "TxFlow describes TxCore order matching and margin alongside TxEVM on the same chain. Internal shared settlement does not mean that external deposits avoid bridges.",
      "limitation": "Throughput, finality, uptime, decentralisation and executable liquidity were not independently measured."
    },
    {
      "id": "txflow-02",
      "area": "Perpetual fees",
      "source": "https://docs.txflow.com/perp/trading-fees",
      "finding": "The published VIP 0 rates are 0.015% maker and 0.045% taker, charged on notional for each side of a trade.",
      "limitation": "Confirm the actual account tier and order preview. Fees on entry and exit both matter."
    },
    {
      "id": "txflow-03",
      "area": "Spot fees",
      "source": "https://docs.txflow.com/spot/trading-fees",
      "finding": "The published VIP 0 spot rates are 0.040% maker and 0.070% taker. Spot and perpetual volume contribute to the rolling 14-day tier calculation.",
      "limitation": "A shared tier calculation does not mean identical spot and perpetual fee rates."
    },
    {
      "id": "txflow-04",
      "area": "Funding",
      "source": "https://docs.txflow.com/perp/funding",
      "finding": "Settlement intervals are contract-specific: one, four or eight hours. Positions held at the settlement timestamp pay or receive funding. Positive rates mean longs pay shorts; negative rates reverse that direction.",
      "limitation": "The old universal one-hour description was too broad. Check the exact instrument and next settlement."
    },
    {
      "id": "txflow-05",
      "area": "Collateral and margin",
      "source": "https://docs.txflow.com/perp/accounts-and-margin",
      "finding": "The documentation identifies USDC as perpetual collateral. Cross margin shares collateral; isolated margin allocates a separate position pool.",
      "limitation": "Collateral denomination is not a guarantee of stable value, solvency or withdrawal access."
    },
    {
      "id": "txflow-06",
      "area": "Liquidation",
      "source": "https://docs.txflow.com/perp/liquidations",
      "finding": "The documented trigger compares equity with maintenance margin plus a liquidation fee based on notional and the taker fee. Mark price matters. Cross positions may be liquidated together, including profitable positions.",
      "limitation": "Do not infer liquidation price from leverage alone. Partial liquidation and auto-deleveraging add further dependencies."
    },
    {
      "id": "txflow-07",
      "area": "Vault availability",
      "source": "https://docs.txflow.com/vault/protocol-vault-and-user-vault",
      "finding": "The page retains an early-mainnet statement that the protocol vault is not yet accepting deposits. User-vault creation is described as a selected pilot.",
      "limitation": "A documented vault design is not evidence of open deposit access. Availability in a funded account was not tested."
    },
    {
      "id": "txflow-08",
      "area": "Points",
      "source": "https://docs.txflow.com/points/how-points-work",
      "finding": "Season 1 documentation starts on 12 October 2026 and describes eligible perpetual activity, with spot and prediction activity excluded from that season. The scoring weights are not fully published.",
      "limitation": "No projected reward value is included in the DN calculator. Points do not establish a guaranteed token allocation or return."
    },
    {
      "id": "txflow-09",
      "area": "Gas-free deposit",
      "source": "https://docs.txflow.com/getting-started/gas-free-deposit",
      "finding": "The documented subsidised route uses native Arbitrum USDC, not USDC.e, a minimum of 5 USDC and a self-custody wallet with zero ETH. The described flow excludes social wallets.",
      "limitation": "Gas subsidy is conditional and does not remove trading fees, funding, bridge risk or all transfer costs."
    },
    {
      "id": "txflow-10",
      "area": "Audit scope",
      "source": "https://docs.txflow.com/resources/audits",
      "finding": "The provider links an OpenZeppelin bridge-contract audit.",
      "limitation": "DN checked the audit index, not the report or deployed bytecode. This does not establish a full-chain audit or absence of vulnerabilities."
    },
    {
      "id": "txflow-11",
      "area": "Access terms",
      "source": "https://txflow.com/terms",
      "finding": "The terms restrict covered persons and entities connected to the US, mainland China, Singapore, Canada and the UK, alongside sanctions restrictions, and prohibit geographic circumvention.",
      "limitation": "Read the full residence, citizenship, location and entity tests. Absence from this summary is not permission to use the service."
