Tres Finance — Asset Balance Validation

Overview

This skill validates wallet balances in Tres Finance against DeBank, providing a clear discrepancy report as both an interactive HTML file and a PDF. It compares per-asset token amounts (including DeFi position underlying tokens) for each EVM wallet and flags matches, minor differences, major discrepancies, missing assets, untracked tokens, and unmatched positions.

Scope: Only EVM-compatible wallets are supported (DeBank limitation). Exchange accounts, non-EVM chains, and empty wallets are skipped.

When to Use

Trigger this skill whenever a user asks to:

• Validate or verify their TRES balances
• Cross-check or audit wallets against external on-chain data
• Compare TRES data to DeBank
• Check if their balances are correct

Example phrases:

• "Validate my balances"
• "Check my wallets against DeBank"
• "Are my TRES balances correct?"
• "Show me any discrepancies between TRES and on-chain data"

Prerequisites

Process Overview

Step 1 — Authenticate with TRES

Call get_viewer to confirm the organization name.

Step 2 — Fetch wallets and balances from TRES

IMPORTANT — Timeout handling: The internalAccount query with both balances and positions will timeout for large orgs. Split into two separate queries:

Query 1: Wallets + Balances only (no positions)

query {
  internalAccount {
    results {
      id
      name
      identifier
      isExchange
      platforms
      balances {
        amount
        asset {
          symbol
          contract { identifier }
        }
        fiatValue { value unitPrice fiatCurrency }
      }
    }
  }
}

Note: The amount field is returned as a string, not a number. Always float() it before arithmetic.

Wallet classification:

Supported EVM platforms: Ethereum, Arbitrum, Optimism, Polygon, Base, Avalanche, Binance, Gnosis Chain, zkSync, Fantom, Celo, Berachain, Linea, Scroll, Sonic, HyperEVM.

Step 3 — Fetch DeFi positions from TRES

Do NOT use the positions sub-field on internalAccount — it returns all historical snapshots (can be 3000+ entries per wallet) and will timeout or exceed token limits.

Instead, use the dedicated getStatelessWalletsPositions query which returns current positions only:

query {
  getStatelessWalletsPositions(
    walletIdentifiers: ["0x..."],
    platform: ETHEREUM,
    application: "aave-v3"
  ) {
    walletIdentifier
    displayName
    positionType
    platform
    children {
      symbol
      amount
      assetIdentifier
      fiatValue
    }
    fiatValue
    id
  }
}

Required parameters:

• walletIdentifiers: array of wallet addresses
• platform: must be an enum value like ETHEREUM, POLYGON, ARBITRUM, etc.

Optional but recommended:

• application: filter by protocol (e.g. "aave-v3", "verse", "lido", "merkl", "uniswap-v4", "sablier", "ethena", "stakewise", "quickswap", "steer", "yieldnest", "morphoblue")

IMPORTANT: Without the application filter, the query returns empty results. Always specify the application.

Batching strategy:

1. First, fetch DeBank all_complex_protocol_list for each wallet to discover which protocols have positions
2. Map DeBank protocol names to TRES application names (lowercase, hyphenated)
3. Use GraphQL aliases to batch multiple wallet+platform+application combos into a single query:

query {
  a1: getStatelessWalletsPositions(walletIdentifiers: ["0x..."], platform: ETHEREUM, application: "aave-v3") {
    walletIdentifier displayName positionType platform id
    children { symbol amount assetIdentifier fiatValue }
  }
  a2: getStatelessWalletsPositions(walletIdentifiers: ["0x..."], platform: ETHEREUM, application: "verse") {
    walletIdentifier displayName positionType platform id
    children { symbol amount assetIdentifier fiatValue }
  }
}

Keep each batched query to ~6 aliases max to avoid timeouts.

Step 4 — Retrieve DeBank API key

Read DEBANK_API_KEY from plugin user config — do not ask the user to paste it in chat. If the key is absent or empty, stop and display:

"DEBANK_API_KEY is not configured. Please add it via the plugin settings (obtain your key at https://cloud.debank.com)."

Step 5 — Fetch DeBank data via bash

For each EVM wallet, fetch two endpoints:

1. Token balances: all_token_list — covers all chains without requiring a chain_id
2. DeFi protocol positions: all_complex_protocol_list — returns LP, staking, lending positions with underlying token amounts

Use --data-urlencode with -G so the wallet address is never shell-interpolated into the URL string:

# Token balances
curl -s -G \
  -H "AccessKey: ${user_config.DEBANK_API_KEY}" \
  --data-urlencode "id=$WALLET_ADDR" \
  "https://pro-openapi.debank.com/v1/user/all_token_list"

# DeFi positions
curl -s -G \
  -H "AccessKey: ${user_config.DEBANK_API_KEY}" \
  --data-urlencode "id=$WALLET_ADDR" \
  "https://pro-openapi.debank.com/v1/user/all_complex_protocol_list"

Fiat-value filter: Discard any token where price < 0.01 — these are excluded from all matching, display, and reporting.

Rate limiting: Add a 0.3s delay between wallet requests to avoid 429 errors.

Step 6 — Match regular assets

Matching must be chain-aware. DeBank's all_token_list returns a chain field per token (e.g. "eth", "arb", "bsc"). TRES balances are tied to a specific platform via the wallet's platforms array or the balance's context. Always prefer a per-chain match before falling back to cross-chain aggregation.

Chain ID mapping (DeBank chain → TRES platform):

Matching order (most specific first):

1. Contract + chain match (best): asset.contract.identifier (lowercase) vs DeBank token id (lowercase), on the same chain. This is the most precise match.
2. Symbol + chain match: For native tokens (no contract), match by asset.symbol (case-insensitive) AND DeBank chain matching the TRES platform for that balance row. This correctly handles the common case where a wallet holds ETH on both Ethereum and Arbitrum — each TRES balance row matches its corresponding DeBank per-chain entry.
3. Symbol-only match (last resort): If a TRES native token balance cannot be matched to any specific DeBank chain entry, fall back to symbol-only matching. This handles edge cases where TRES or DeBank uses a different chain label.

Step 7 — Match DeFi position underlying tokens

This is a critical step that compares DeFi position underlying tokens between TRES and DeBank.

7a. Filter out position NFT rows

Remove position NFT tokens from the regular comparison (e.g. UNI-V3-POS, RCL, SAB-LOCKUP, SLP, STEER, UNI-V4-POS). These are replaced by the underlying token rows from positions.

7b. Process TRES positions

From getStatelessWalletsPositions results, for each position:

1. Aggregate children by symbol — a position may have multiple entries for the same token (e.g. supply + unclaimed rewards in QuickSwap or Uniswap V4), so sum the amounts
2. Use displayName to identify the protocol and token composition

# Example: aggregate children for a position
def aggregate_children(children):
    agg = {}
    for c in children:
        sym = c['symbol']
        amt = float(c['amount']) if isinstance(c['amount'], str) else c['amount']
        if sym not in agg:
            agg[sym] = {'amount': 0, 'assetIdentifier': c.get('assetIdentifier', '')}
        agg[sym]['amount'] += amt
    return agg

7c. Process DeBank positions

From all_complex_protocol_list, for each protocol's portfolio_item_list:

1. Extract asset_token_list for supply tokens and reward_token_list for rewards
2. Use protocol name and item name (e.g. "Lending", "Liquidity Pool") as the position label

7d. Compare position tokens

Match DeBank protocol positions to TRES positions by:

1. Protocol name match (case-insensitive, first word)
2. Token symbol overlap between children

For each matched position token:

• If TRES data exists: Compare amounts, compute delta %, assign match/minor/major status
• If no TRES data: Assign position status (purple badge)

Step 8 — Build and render the report

Create two outputs:

1. Interactive HTML file — Dark-themed, with filter buttons, collapsible wallet cards, dedicated DeFi Positions section per wallet
2. PDF report — Landscape A4, all wallet tables expanded, using reportlab

Save both to the outputs directory.

Report Layout — CRITICAL

DeFi Positions must be visually separated

Each wallet card in the report MUST have two distinct sections:

1. DeFi Positions section (top, purple-themed) — A dedicated box with purple border and dark purple background (#1a1033 bg, #7c3aed border) showing all position-related rows. This section appears BEFORE the regular token table.

2. Regular tokens table (below) — Standard token balance comparison rows.

Position asset indicator

Every position asset row MUST have a purple dot indicator (CSS circle, 8px, #a855f7) next to the asset name. This ensures positions are instantly recognizable:

<span style="display:inline-block;width:8px;height:8px;background:#a855f7;border-radius:50%;margin-right:6px;vertical-align:middle;"></span>

Do NOT use emojis or inline SVGs — they may not render in all viewers. Use pure CSS shapes only.

Position rows show dual badges

Position rows that have a TRES match show TWO badges:

• A POSITION badge (purple)
• A match-status badge (MATCH/MINOR/MAJOR)

Auto-expand wallets with positions

Wallet cards that contain DeFi positions should be auto-expanded (<details open>) so positions are immediately visible.

Number Formatting Rules

Token amounts

• Max 3 decimal places for all amounts
• Amounts ≥ 1,000: use comma separator with 3 decimals (e.g., 846,492.356)
• Amounts < 1,000: use 3 decimals (e.g., 0.386)
• Very small amounts (< 0.000001): use scientific notation (e.g., 3.54e-07)
• Null/missing: show em dash —

function formatAmount(n) {
  if (n === null || n === undefined) return '\u2014';
  if (Math.abs(n) < 0.000001) return n.toExponential(2);
  if (Math.abs(n) >= 1000) return n.toLocaleString('en-US', {minimumFractionDigits: 2, maximumFractionDigits: 3});
  return n.toFixed(3);
}

Fiat values

• Shown in parentheses next to every token amount: 846,492.356 ($17,562.21)
• Shown in parentheses next to every delta %: 5.33% ($81.21)
• Format: ($X,XXX.XX) — always 2 decimal places, comma-separated thousands
• Null/missing: omit entirely (no empty parentheses)

Fiat value computation — CRITICAL

Use a single price source (DeBank's token price) to compute fiat values for both the TRES and DeBank columns. This ensures:

• When amounts match, the fiat delta is $0 (not inflated by pricing source differences)
• The fiat delta next to delta % represents the actual USD value of the amount discrepancy

# For regular tokens:
price = debank_token['price']  # single source
tres_fiat = tres_amount * price
debank_fiat = debank_amount * price
delta_fiat = abs(tres_amount - debank_amount) * price

# For position tokens — same principle:
price = debank_asset_token['price']
tres_fiat = tres_aggregated_amount * price
debank_fiat = debank_amount * price
delta_fiat = abs(tres_aggregated_amount - debank_amount) * price

Do NOT use TRES fiatValue for the TRES column and DeBank price for the DeBank column — this creates misleading fiat deltas when TRES and DeBank use different token prices.

Native Token Matching (Multi-Chain Wallets)

Native tokens (ETH, BNB, etc.) often appear on multiple chains in TRES for a single wallet (e.g., ETH on Ethereum + ETH on Arbitrum). DeBank's all_token_list returns separate per-chain entries with a chain field — it does NOT aggregate them.

Rule: match per-chain first, aggregate only as a last resort.

1. Per-chain match (default): For each TRES native token balance, use the balance's platform context to find the corresponding DeBank entry by symbol + chain. For example, a wallet with 0.00956 ETH on Ethereum and 0.001168 ETH on Arbitrum should produce two separate comparison rows — one matched to DeBank's chain: "eth" entry and one to chain: "arb".

2. Aggregation fallback (rare): Only aggregate TRES balances across chains when DeBank returns fewer entries than TRES for the same symbol. This can happen if DeBank merges certain bridged token balances. When aggregating, add a note like "Aggregated: ETH (eth) + ETH (arb)".

Why this matters: Blindly aggregating before comparing creates false discrepancies. If Ethereum ETH matches perfectly but Arbitrum ETH has a gap, aggregation masks the Ethereum match and produces a single misleading delta. Per-chain matching preserves granularity and makes it easy to identify exactly which chain is out of sync.

Status Badges

Report Sections

The rendered report (both HTML and PDF) includes:

1. Summary cards — Wallets checked, assets compared, matched, minor, major, missing, untracked, positions, and match rate %
2. Filter bar (HTML only) — Buttons to filter by status: All, Match, Minor, Major, Missing, Untracked, Position
3. Per-wallet card containing:
   • DeFi Positions box (purple-themed, at top) — Position assets with purple dot indicator, protocol label, dual status badges
   • Regular tokens table — Each asset with symbol, chain, TRES amount (+ fiat), DeBank amount (+ fiat), delta % (+ fiat delta), status badge
4. Skipped wallets — List of wallets not validated and the reason why
5. Notes & Caveats — Sync lag, DeFi positions explanation, native token aggregation, price filter, missing/untracked explanations

Important Caveats

• Sync lag: TRES balances reflect the last sync time. Recent on-chain activity may show as a discrepancy.
• DeFi positions: Underlying tokens from LP, staking, and lending positions are shown as individual rows in a dedicated purple section. Both TRES and DeBank amounts are compared where TRES position data is available. Active LP positions will naturally show some discrepancy because TRES and DeBank snapshot at different times.
• Native token matching: ETH, BNB, etc. are matched per-chain first (using DeBank's chain field mapped to TRES platforms). Multi-chain balances are only aggregated as a fallback when DeBank returns fewer entries than TRES for the same symbol.
• Multi-chain coverage: DeBank all_token_list covers all chains; tokens on chains not configured in TRES appear as "Untracked."
• Price filter: Tokens with price < $0.01 (zero-price, null, or micro-cap) are excluded from all reports.
• Missing in DeBank: Typically spam/airdrop tokens (HEX, ASCZBR, etc.) that DeBank filters out.
• Untracked in TRES: Tokens on chains not configured in TRES, or small dust amounts.

Error Handling

Next Steps (after report renders)

• Re-run — Rebuild the report with fresh data at any time
• Drill down — For any Major discrepancy, inspect the specific asset across platforms in TRES to identify which chain is out of sync
• Position discrepancies — Minor discrepancies on active LP positions are expected due to different snapshot times between TRES and DeBank
