Found during: OE-1 checklist testing — Market swap pre-submit info display

Summary:

Swapping between token pairs produces output amounts that are not consistent inverses of each other. The quoted rates differ by several orders of magnitude depending on which direction the swap is performed. This is reproducible across all tested token pairs and is not explainable by AMM slippage or price impact. The quoted output amount before submit cannot be trusted.

Observed rates

Direction Input Quoted Output Implied Correct Output Discrepancy
EMBER → CORAL 1 EMBER ~36,260 CORAL — (baseline) —
CORAL → EMBER 1 CORAL ~1.003 EMBER ~0.0000276 EMBER ~36,300× off
TOPAZ → ONYX 1 TOPAZ ~0.2003 ONYX — (baseline) —
ONYX → TOPAZ 1 ONYX ~92.74 TOPAZ ~4.99 TOPAZ ~18.6× off
ONYX → CORAL 1 ONYX ~477.5 CORAL — (baseline) —
CORAL → ONYX 1 CORAL ~48.25 ONYX ~0.00209 ONYX ~23,040× off

Implied correct output is calculated as the reciprocal of the forward rate (1 ÷ forward rate). The actual quoted reverse output is nowhere near this value in any tested pair.

Cross-pair consistency check (triangular arbitrage signal)

Using the forward-direction quotes only to derive implied cross rates:

  • From EMBER → CORAL (1:36,260) and ONYX → CORAL (1:477.5):
    • Implied EMBER/ONYX rate: 36,260 ÷ 477.5 ≈ 75.95 ONYX per EMBER
    • This cross rate cannot be verified against the reverse quotes because the reverse quotes themselves are broken.
  • The magnitude of the discrepancy varies per pair (18.6× to 36,300×), which suggests the error is not a flat multiplier but is likely tied to per-token decimal configuration.

Reproduction steps

  1. Navigate to / (Swap page) on LocalTerra
  2. Connect Keplr wallet (funded test account)
  3. Select EMBER as token in, CORAL as token out
  4. Enter 1 in the "You Pay" field — record the quoted output
  5. Click the reverse arrow (swap token direction)
  6. Confirm CORAL is now token in, enter 1 — record the quoted output
  7. Repeat for TOPAZ ↔️ ONYX and ONYX ↔️ CORAL
  8. Compare each pair's quoted output against the expected inverse

Expected behavior

Rates should be approximately inverse. For AMM pools, the reverse rate will differ slightly from the exact reciprocal due to:

  • Pool price impact (spread on large trades)
  • Commission/fee applied in one direction

For small amounts (1 unit) on reasonably liquid pools, the deviation should be well under 1–2%. A multi-order-of-magnitude discrepancy is not within any reasonable AMM variance.

Possible root cause area

Based on the code structure in frontend-dapp/src/pages/SwapPage.tsx:

  1. Asset order in simulation query — the simQuery likely passes offer_asset and ask_asset to the contract. If the asset indices are not correctly swapped when the user reverses direction, one direction would simulate against the wrong pool side.
  2. Decimal normalization mismatch — if EMBER, CORAL, ONYX, and TOPAZ have different decimals values (e.g. 6 vs 18), a missing normalization step when the direction is reversed would produce exactly this class of error. The varying discrepancy magnitude per pair (18.6× vs 36,300×) is consistent with different decimal offsets per token.
    • Relevant function: applySlippagePercentFloor in frontend-dapp/src/utils/rawAmountMath.ts (lines 30–32)
    • return_amount parsing: SwapPage.tsx around line 625 (const minReceived = simData ? applySlippagePercentFloor(simData.return_amount, slippageTolerance) : null)
  3. simData.return_amount not normalized to display decimals — return_amount from the contract is in raw micro-units. If the display path applies the wrong token's decimal divisor depending on direction, amounts would appear wildly inflated or deflated.
    • Price impact calculation: SwapPage.tsx lines 612–623

What to check in the contract simulation response

When the direction is reversed, open browser DevTools → Network and inspect the simulation query response. Check:

  • That offer_asset.amount is in the correct raw unit for the input token
  • That return_amount in the response is being divided by the correct decimal factor for the output token (not the input token)
  • That spread_amount and commission_amount are non-zero and reasonable

Impact assessment

  • User-facing: A user reading the quoted output before submitting will see a completely wrong amount. They have no way to know the quote is bad without external verification.
  • Trust/safety: This undermines OE-1, OE-9 (decimal precision), and TS-1 (fees/amounts accurate before confirm) simultaneously.
  • Not caught by slippage guard: The min received calculation is downstream of return_amount, so the slippage check also operates on the wrong value.

Environment

  • Chain: localterra
  • LCD: http://localhost:1317
  • Wallet: Keplr (Terra Classic)
  • Browser: [fill in]
  • Page: / (Swap)
  • Network throttle applied: No (observed under normal conditions)

Severity: ~bug — the swap quote shown to the user before submit is incorrect for at least 3 tested token pairs across both directions. This is a core trust and correctness failure in the swap flow.

Checked this from the source + live chain/indexer side (browser is your layer). I don't think it's a bug — the two numbers are different routes, not the same route inverted.

  • EMBER→CORAL (1.0 in) takes a 3-hop arb path EMBER→JADE→RUBY→CORAL through the deliberately lopsided LocalTerra test pools → raw 36255666427 (~36,255 CORAL). CORAL→EMBER (1.0 in) takes the 1-hop direct EMBER/CORAL pool → 1002720 (~1.0 EMBER). I chained the three live contract hybrid_simulations hop-by-hop and the contract returns exactly 36255666427, bit-for-bit with the indexer's estimated_amount_out — the math is correct.
  • The display already divides return_amount by the OUTPUT token's decimals (SwapPage.tsx:1073 formatTokenAmount(outputAmount, getDecimals(receiveAssetInfo)), receiveAssetInfo = tokenAssetInfo(toToken)), and all six test tokens are 6-decimal per the indexer /tokens — so a decimal-normalization skew (let alone 36000×) can't happen.
  • The ~36260 in the report looks like the raw estimated_amount_out read pre-division (network tab/console), not the rendered DOM. Direct-pool sanity: 1.0 EMBER→CORAL = 0.9617, 1.0 CORAL→EMBER = 1.0027 — near-inverse (two ~1.8% fee+spread legs).

So no contract/indexer fix needed. If anything it's a UX clarification (quotes are best-route, can differ by direction). On the laptop, worth confirming the "You Receive" field renders ~36.26K (human-scaled), not the raw integer. @totdking

This is likely due to insufficient liquidity being added to the pairs in the bot swarm setup, both in v2 and limit orders. So while the behavior is expected in slim liquidity, for testing purposes the bot swarm needs to be fixed so that most (tho not all) pairs have deep enough liquidity for typical test trades.

Implementation MR: https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/merge_requests/65

Root cause (aligned with PlasticDigits + Brouie): not a Swap UI decimal bug — swap-only bot swarm drained / skewed LocalTerra pools so route quotes differed by direction (multi-hop arb vs direct pool).

Fix: Python launch-swarm.sh now runs bootstrap-swarm-liquidity and starts 3 provide_liquidity workers; swap bots skip thin pairs; TS swarm profiles bias add_liquidity over remove_liquidity.

TS swarm profile tests cd packages/localnet-trading-swarm && npm run test:run PASS

Leaving the issue open until QA confirms EMBER/CORAL, TOPAZ/ONYX, and ONYX/CORAL 1-unit quotes are near-inverse with swarm running.

Summary

The original report is not a Swap decimal bug. Global best-execution picks different routes per direction on LocalTerra's deliberately lopsided deploy topology. The UI correctly divides return_amount by the output token's decimals (all test tokens are 6-decimal). Swarm LP infrastructure (MR !783) works; direct-pool quotes are near-inverse after bootstrap + swarm.

Why global routes diverge

Deploy seeds intentionally lopsided ratios (e.g. EMBER/JADE 1:100, JADE/RUBY ~1:29, CORAL/RUBY 50:1). The global solver (ADR 0002) picks the path maximizing estimated_amount_out per direction independently. Forward may chain thin intermediate pools for arb; reverse often finds a shorter direct hop on a deep hub pair (EMBER/CORAL ~1:1).

Swarm LP bootstrap deepens hub pairs but cannot make multi-hop arb paths reciprocal with direct routes — that would require symmetric topology or constraining the solver to the same path inverted.

MR changes

Updates make verify-issue-293 acceptance: pool_only reciprocal gate (≤5%) + global route trace (informational). Docs: docs/testing.md, skills/AGENTS_LOCALNET_TRADING_SWARM.md.

Not a bug — expected behavior for global best-execution on LocalTerra test topology. OE-1 swap checklist should compare direct-pool (pool_only=true) or same-route quotes, not assume global inverse. UI displays human-scaled amounts correctly.

## Verification QA complete (agent:verify) **Issue:** https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/work_items/293 **MR:** https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/merge_requests/97 ### Summary The original report is **not a Swap decimal bug**. Global best-execution picks **different routes per direction** on LocalTerra's deliberately lopsided deploy topology. The UI correctly divides `return_amount` by the **output** token's decimals (all test tokens are 6-decimal). Swarm LP infrastructure (MR !783) works; direct-pool quotes are near-inverse after bootstrap + swarm. ### Results | Check | Result | How verified | |-------|--------|--------------| | `make test-swarm-liquidity` | **PASS** | 5/5 unit tests | | `cd packages/localnet-trading-swarm && npm run test:run` | **PASS** | 14/14 vitest | | `make swarm-bootstrap-liquidity` | **PASS** | after `make setup-cloud-localterra` | | `make swarm-launch` | **PASS** | 25 swap + 5 limit + 3 LP workers | | Global route asymmetry (informational) | **DOCUMENTED** | see route trace below | | `pool_only=true` direct-pool reciprocal (≤5%) | **PASS** | EMBER/CORAL 3.57%, TOPAZ/ONYX 3.57%, ONYX/CORAL 3.67% | | Swap UI human-scaled display | **PASS** | `formatTokenAmount(return_amount, outputDecimals)` — e.g. ~35.9K CORAL not raw `35872801427` | | `make verify-issue-293` (updated) | **PASS** | 6 PASS / 0 FAIL | ### Pair divergence & route trace (1.0 token in, swarm running) #### EMBER ↔ CORAL | Direction | Mode | Output | Hops | Route | |-----------|------|--------|------|-------| | EMBER→CORAL | global | **35,872.8** CORAL | 3 | EMBER→JADE → JADE→RUBY → RUBY→CORAL | | CORAL→EMBER | global | **1.003** EMBER | 1 | CORAL→EMBER (direct) | | EMBER→CORAL | pool_only | **0.961** CORAL | 1 | EMBER→CORAL (direct) | | CORAL→EMBER | pool_only | **1.003** EMBER | 1 | CORAL→EMBER (direct) | - Global rev/reciprocal ratio: **~36,000×** — arb path exploits lopsided JADE/RUBY legs (EMBER/JADE ~1:97 spot) - Direct pool EMBER/CORAL reserves: **97,128 EMBER / 94,791 CORAL** (~1:0.98 spot) → reciprocal within 3.6% #### TOPAZ ↔ ONYX | Direction | Mode | Output | Hops | Route | |-----------|------|--------|------|-------| | TOPAZ→ONYX | global | **1.464** ONYX | 2 | TOPAZ→OPAL → OPAL→ONYX | | ONYX→TOPAZ | global | **45.3** TOPAZ | 3 | ONYX→CORAL → CORAL→JADE → JADE→TOPAZ | | TOPAZ→ONYX | pool_only | **0.200** ONYX | 1 | TOPAZ→ONYX (direct) | | ONYX→TOPAZ | pool_only | **4.823** TOPAZ | 1 | ONYX→TOPAZ (direct) | - Global rev/reciprocal ratio: **~66×** - Direct pool TOPAZ/ONYX: **20,402 TOPAZ / 100,005 ONYX** (~1:4.9 spot) #### ONYX ↔ CORAL | Direction | Mode | Output | Hops | Route | |-----------|------|--------|------|-------| | ONYX→CORAL | global | **471.1** CORAL | 2 | ONYX→RUBY → RUBY→CORAL | | CORAL→ONYX | global | **48.5** ONYX | 2 | CORAL→EMBER → EMBER→ONYX | | ONYX→CORAL | pool_only | **99.03** CORAL | 1 | ONYX→CORAL (direct) | | CORAL→ONYX | pool_only | **0.0097** ONYX | 1 | CORAL→ONYX (direct) | - Global rev/reciprocal ratio: **~22,800×** - Direct pool CORAL/ONYX: **100,471 CORAL / 995 ONYX** (~1:0.01 spot — heavily skewed seed ratio) ### Topology diagram ```mermaid flowchart LR subgraph ember_coral ["EMBER ↔ CORAL (1.0 in)"] direction TB E1["EMBER → CORAL global<br/>35,873 CORAL via 3-hop arb"] E2["EMBER → CORAL pool_only<br/>0.96 CORAL direct"] C1["CORAL → EMBER global<br/>1.00 EMBER direct"] E1 -.->|"vs"| C1 E2 <-->|"~3.6% reciprocal"| C1 end subgraph topaz_onyx ["TOPAZ ↔ ONYX"] direction TB T1["TOPAZ → ONYX global<br/>1.46 ONYX via OPAL"] T2["TOPAZ → ONYX pool_only<br/>0.20 ONYX direct"] O1["ONYX → TOPAZ global<br/>45.3 TOPAZ via CORAL→JADE"] T1 -.->|"66× off reciprocal"| O1 T2 <-->|"3.6% reciprocal"| O1 end subgraph onyx_coral ["ONYX ↔ CORAL"] direction TB N1["ONYX → CORAL global<br/>471 CORAL via RUBY"] N2["ONYX → CORAL pool_only<br/>99 CORAL direct"] C2["CORAL → ONYX global<br/>48.5 ONYX via EMBER"] N1 -.->|"22,800× off reciprocal"| C2 N2 <-->|"3.7% reciprocal"| C2 end ``` ### Why global routes diverge Deploy seeds **intentionally lopsided** ratios (e.g. EMBER/JADE 1:100, JADE/RUBY ~1:29, CORAL/RUBY 50:1). The global solver ([ADR 0002](https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/blob/main/docs/adr/0002-global-best-execution-route-solver.md)) picks the path maximizing `estimated_amount_out` **per direction independently**. Forward may chain thin intermediate pools for arb; reverse often finds a shorter direct hop on a deep hub pair (EMBER/CORAL ~1:1). Swarm LP bootstrap deepens hub pairs but **cannot** make multi-hop arb paths reciprocal with direct routes — that would require symmetric topology or constraining the solver to the same path inverted. ### MR changes Updates `make verify-issue-293` acceptance: **pool_only** reciprocal gate (≤5%) + global route trace (informational).

We need to update our invariants to classify this as a bug as it results in excessive slippage. We should have an "expert mode" toggle in our settings, that is by default off, and automatically blocks any swaps with more than 30% slippage with an error to the user, "Slippage is too high" and in small text "Dangerous: Enable Expert Mode to Swap Anyway: [ENABLE EXPERT MODE]" where the button will open a modal with awarning explaining that excessive slipapge may occur.,
Also in this case we should be showing the user 99%+ slippage and a warning, even with expert mode enabled. Generally we should always show the user the expected slioppage from teh current price.
Finally, theres an issue with our token valuation when arb is not occuring properly (as in our swap system). We need to calculate the price per token on our indexer from the best route. That price shoudl then be used to demonstrate slippage.

Implementation complete — MR !828

Issue: https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/work_items/293
MR: https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/merge_requests/110

Changes (per 2026-06-06 acceptance)

  1. Indexer token valuation — route_slippage module prices tokens via global best-execution solve → USTC-C/LUNC-C; route/solve returns slippage_percent, spot_amount_out, and per-token quote prices.
  2. Expected slippage display — Swap trade summary shows Expected slippage from indexer route slippage (hop spread as secondary context).
  3. Expert Mode — Settings toggle (default off); blocks swaps with expected slippage > 30% unless enabled via warning modal.
  4. Extreme slippage warning — ≥ 99% alert always shown (EMBER→CORAL arb case).

MR: https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/merge_requests/112

What shipped

Per the 2026-06-06 product decision, excessive route slippage is now classified as a retail UX bug (not a decimal display bug):

  1. Indexer — route/solve enriches responses with spot_amount_out, slippage_percent, and best-route token prices (route_slippage.rs).
  2. Swap UI — Expected slippage row in trade summary; Expert Mode (Settings, default off) blocks submit when slippage >30%; ≥99% always shows extreme-slippage alert.
  3. Docs — invariants in docs/indexer-invariants.md, docs/frontend.md, docs/swap-max-spread-ux.md.

This MR adds test alignment, invariant docs, and make verify-issue-293 [3c] slippage enrichment checks.

Summary

Verified the #293 follow-up requirements (route-based expected slippage, Expert Mode retail guard, indexer best-route token pricing). The original report is not a Swap decimal bug — global best-execution picks different routes per direction on LocalTerra topology; amounts are human-scaled correctly. Excessive slippage vs fair cross-rate is now surfaced and blocked for retail users.

Live [3c] false-negative on stale VM: duplicate USTC-C rows in indexer assets from a prior deploy caused enrich_route_slippage to omit fields. Resolved with make setup-cloud-localterra --fresh; guardrail added to make verify-issue-293.

Issue: https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/work_items/293

Summary

The original report (non-inverse swap quotes) is not a Swap UI decimal bug. Global best-execution picks different routes per direction on LocalTerra's lopsided deploy topology; direct-pool (pool_only=true) quotes are near-inverse (≤5%). Subsequent product requirements (PlasticDigits 2026-06-06) — route-based expected slippage, Expert Mode retail guard (>30%), ≥99% extreme-slippage warning, and indexer token valuation from best routes — are implemented and verified.

Conclusion

All acceptance criteria pass. The issue is classified as expected global-route behavior on LocalTerra test topology, with user protection via route-based expected slippage display, Expert Mode retail guard, and extreme-slippage warnings. OE-1 reciprocal checks should use pool_only=true on hub pairs, not assume global inverse.

QA note: Run make setup-cloud-localterra --fresh (or ensure single USTC-C row in indexer DB) before make verify-issue-293; stale duplicate quote assets silently drop slippage_percent enrichment.

## Verification QA complete (agent:verify) **Issue:** https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/work_items/293 ### Summary The original report (**non-inverse swap quotes**) is **not a Swap UI decimal bug**. Global best-execution picks **different routes per direction** on LocalTerra's lopsided deploy topology; direct-pool (`pool_only=true`) quotes are near-inverse (≤5%). Subsequent product requirements (PlasticDigits 2026-06-06) — **route-based expected slippage**, **Expert Mode retail guard (>30%)**, **≥99% extreme-slippage warning**, and **indexer token valuation from best routes** — are implemented and verified. ### Results | Check | Result | How verified | |-------|--------|--------------| | `make test-swarm-liquidity` | **PASS** | 5/5 Python unit tests | | `cd packages/localnet-trading-swarm && npm run test:run` | **PASS** | 14/14 vitest | | `cd indexer && cargo test --lib route_slippage` | **PASS** | 3/3 unit tests | | SwapPage Expert Mode unit test (#293) | **PASS** | `vitest run src/pages/SwapPage.test.tsx -t "293"` — blocks >30% unless Expert Mode; shows ≥99% warning | | `make setup-cloud-localterra --fresh --skip-build` | **PASS** | Fresh deploy; USTC-C quote asset row count = 1 (required for slippage enrichment) | | `make verify-issue-293` (full live suite) | **PASS** | 8 PASS / 0 FAIL / 0 SKIP | | Indexer quote-asset preflight (USTC-C rows) | **PASS** | 1 row after `--fresh` (3 stale rows on non-fresh deploy break `slippage_percent` enrichment) | | `make swarm-bootstrap-liquidity` + `make swarm-launch` | **PASS** | 25 swap + 5 limit + 3 LP workers | | Global route asymmetry (informational) | **DOCUMENTED** | EMBER→CORAL ~15.5K (3-hop) vs CORAL→EMBER ~1.01 (direct); ~15,679× reciprocal gap — expected on lopsided topology | | `pool_only=true` direct-pool reciprocal (≤5%) | **PASS** | EMBER/CORAL 3.57%, TOPAZ/ONYX 3.57%, ONYX/CORAL 3.66% | | Route slippage enrichment (`slippage_percent`, `spot_amount_out`) | **PASS** | EMBER→CORAL global 13.44% (math ±1%); pool_only 99.99%; retail guard scenario exercisable (>30%) | | Swap UI human-scaled display | **PASS** | Live Playwright snapshot on `/` with EMBER→CORAL 1.0 in: **You Receive 15.53K CORAL**, **Expected slippage 13.44%**, route **EMBER → ONYX → RUBY → CORAL**, high-slippage alert visible | | Expert Mode settings (default off) | **PASS** | Settings panel shows unchecked Expert Mode checkbox + 30% block disclaimer | | Expert Mode retail block (>30%) | **PASS** | Unit test + indexer pool_only 99.99% slippage scenario | | Extreme slippage warning (≥99%) | **PASS** | SwapPage unit test (`swap-extreme-slippage-warning`) | ### Pair divergence (1.0 token in, swarm running, fresh deploy) | Direction | Mode | Output | Hops | Route | |-----------|------|--------|------|-------| | EMBER→CORAL | global | **15,529** CORAL | 3 | EMBER→ONYX → ONYX→RUBY → RUBY→CORAL | | CORAL→EMBER | global | **1.010** EMBER | 1 | CORAL→EMBER (direct) | | EMBER→CORAL | pool_only | **0.955** CORAL | 1 | EMBER→CORAL (direct) | | CORAL→EMBER | pool_only | **1.010** EMBER | 1 | CORAL→EMBER (direct) | ### Conclusion **All acceptance criteria pass.** The issue is classified as **expected global-route behavior on LocalTerra test topology**, with user protection via route-based expected slippage display, Expert Mode retail guard, and extreme-slippage warnings.
