Now that add-liquidity and pool creation submit via addLiquidity / createPool,
the legacy submitNewPosition path is dead. Remove it end to end.
App backend (AmmUiBackend):
- Drop the submitNewPosition slot/method and its newPositionError helper.
Module (AmmModuleImpl):
- Drop submitNewPosition, the m_requestPending guard, and the now-orphaned
nowMs/parseU64 helpers (+ the <chrono> include).
FFI (amm_ffi) — the plan op only submitNewPosition called:
- Delete plan.rs; remove amm_plan (extern + regenerated header), api::plan,
and PlanRequest.
- Remove the plan-only machinery it fed: QuoteBranch, NewPositionPlan,
EvaluatedQuote.plan/quote_hash, and AccountPlan's wallet_args /
requires_fresh_lp / contains / validate_ready, plus the plan construction
in quote.rs.
- Tests: drop the plan-only tests/helpers; keep quote coverage by trimming
the mixed tests to their quote assertions.
QML tests (tst_LiquidityPage):
- Remove the two legacy-submit tests (base58-only success) + the
submitNewPosition mock and its now-unused fixtures. Keep the
finishSubmitFailure test (unchanged behaviour).
quoteNewPosition and its machinery (amm_quote, buildQuoteInput, PairSnapshot,
AccountPlan preview/sources, commitment) stay — they retire with the legacy
quoting in the quote-migration vertical.
Migrate the active-pool branch of the liquidity form onto the new addLiquidity
op (quoting stays on legacy quoteNewPosition for now, as agreed).
- AmmUiBackend: add the addLiquidity QtRO slot; forwards to the module and
refreshes balances (mirrors createPool).
- NewPositionFlow: route the active-pool confirm to addLiquidity, minting a
fresh LP holding then submitting {tokenA/B, holdingA/B, lpHolding, maxAmountA/B,
minLpRaw, deadline}. minLpRaw comes from the legacy quote's minimumLpRaw.
- NewPositionForm: show the per-side account selectors in add mode; gate the CTA
on both holdings and on the deposit amounts being present (hasDepositAmounts) —
the pair's probe quote otherwise reports canSubmit on simulated amounts and
wrongly enables the button before any amount is entered.
- amm_ffi: fix add_liquidity_plan to orient the (max amount, holding) pair to the
pool's STORED definition order, not is_canonical_pair — a pool created outside
the FFI (the testnet setup's spel new-definition) can store a non-canonical
order, which otherwise sent a holding into the wrong vault (Transfer
sender/recipient definition mismatch). Test uses a non-canonical pool.
Adds add-liquidity.mjs: asserts the CTA stays disabled with no amounts, submits
an add to the seeded A/B pool, and verifies reserveA grew on-chain.
Add per-side account selectors to the create-pool form, sourced from the
wallet's token holdings, so a user holding a token in several accounts chooses
which funds each deposit. A single holding auto-selects.
Mirrors the swap card: the selector lives inside the token input card, below
the token button. AmmTokenAmountSurface gains an optional footer slot (unchanged
when unset, so add-liquidity renders as before); TokenAmountInput fills it with a
ProgramAccountSelector filtered on the token's base58 definitionId.
- LiquidityPage fetches backend.tokenHoldings(), refetching when the wallet opens
- NewPositionForm routes the chosen holdings into submissionSnapshot's createPool
call; canConfirm now requires both holdings when creating a pool (add-liquidity
is untouched — it enumerates holdings server-side)
- create-pool.mjs selects the funding account for each side before submitting
canSubmit now requires a chosen holding on both swap sides, so the swap e2e
test must select them first. The selector auto-selects a single holding, but
pick it explicitly (robust to multi-account wallets) via a new selectAccount
step that waits for the holdings to load and selects the first match.
Expose each side's selector via selectorObjectName (swapSell/BuyAccountSelector)
and surface sellHolding/buyHolding in the failure diagnostics.
Add a per-slot account selector to the swap card's sell/buy inputs, sourced
from the wallet's token holdings, so a user holding a token in several accounts
chooses which funds each side. A single holding auto-selects.
- SwapPage fetches backend.tokenHoldings(), refetching when the wallet opens
- TokenInput embeds ProgramAccountSelector (half width, right-aligned) in a
full-width row below the amount/token row; exposes it as selectedHoldingId
- SwapCard drives swapExactInput/Output with the selected holdings and blocks
submit ("Select token accounts") until both are chosen
- ProgramAccountSelector gains showWhenSingle + textAlignment opt-ins
A thin source for the account selector: an amm_ffi op that decodes the wallet's
fungible TokenHoldings (owned by the configured token program) into
[{ accountId (hex), accountType:\"TokenHolding\", definitionId (base58),
definitionIdHex (hex), balanceRaw }] — one row per holding account, every token,
including zero-balance holdings; narrowing to a specific token is the selector's
job. Exposed via AmmModuleImpl::tokenHoldings and the AmmUiBackend tokenHoldings()
slot, both gated on wallet-open.
- setup-amm-testnet.sh: mint a third token (TKC), appended to ACCOUNT_LABELS so
the deterministic a/b/lp ids don't shift and left unseeded (only A/B is created)
for the test to create the A/C pair. Split wallet restore from account
registration (ensure_accounts always runs) so adding a token needs no re-restore.
- create-pool.mjs: drives the Liquidity view to create the A/C pool, then verifies
it on-chain via the swap card's resolvePool. evaluate() fallbacks for the
submit/confirm buttons (synthetic clicks aren't reliable on QtQuick Buttons).
- Adds test-hook objectNames (newPositionSubmitButton, liquidityConfirmDialog).
Route pool creation through the redesigned createPool op and retire the old
create-flow machinery. Add-liquidity stays on the legacy submitNewPosition.
Module (amm_module):
- createPool becomes a single-param envelope: it reads the caller-provided
lpHoldingId from the request (a new pool has no pre-existing LP holding),
dropping the requires-fresh-lp handshake — the module never creates wallet
accounts. Returns { status, error, transactionId }; unlike the swaps, a
submit failure carries a code so the UI can explain why.
Backend (AmmUiBackend):
- Expose liquidityQuote (read-only preview) and createPool slots. createPool
guards on the app's wallet-open state, forwards the request, and refreshes
balances on success. No account creation here.
UI (liquidity flow/form):
- NewPositionFlow.confirm() branches on the missing-pool signal: create ->
createPool (mint a fresh public LP account via createAccountPublic, then
submit); add -> unchanged submitNewPosition. Hex transactionId accepted.
- submissionSnapshot supplies canonical-order holdingAId/holdingBId.
- (liquidityQuote is wired to the backend but the create preview still rides
the legacy quote for now.)
Cleanup: the pool-creation confirmation poll is orphaned now that create no
longer submits via submitNewPosition. It polled the pool account by re-quoting
until poolStatus flipped to active_pool — a stopgap for the missing
transactionStatus/poll_tx on the lez module. Removed pendingPoolProbes,
poolPoller, watchPoolCreation, pollPendingPool, finishPoolProbe,
rotate/removePendingPool, pairKey, matchesSelectedPair,
selectedPoolCreationPending, poolActivated, the poolCreationPending state,
acceptPoolActivation, and their now-obsolete tests.
Wire the Buy direction to submit: AmmUiBackend gains a swapExactOutput slot
(guarded like swapExactInput), SwapCard.executeSwap branches on direction —
sell -> swapExactInput(minReceivedRaw), buy -> swapExactOutput(maxInRaw) — and
canSubmit/submitButtonText/buildSnapshot handle both. The confirmation dialog
switches wording by mode ("You pay at most" / "You receive exactly" for exact
output). The Buy field is now digitsOnly since its value is submitted as a raw
base-units integer.
With both directions priced and oriented by the module, the client no longer
needs any pool math. Remove the reserve-orientation chain (sellIsPoolA,
buy/sellReserveNum, poolReserveA/B, poolDefAHex) — resolvePool now reports only
existence and fee — and the now-dead helpers (formatBaseUnits/formatAmountValue,
DummySwapState.amountInFor/minReceived/priceImpactPercent/maxSent). The
impossible-swap guard moves from a client reserve compare to the module's
output_exceeds_liquidity error, surfaced as "Insufficient liquidity".
Wire the Buy direction of the swap card to the module's server-side
swapExactOutQuote, mirroring the exact-input path. AmmUiBackend gains a
swapExactOutQuote(tokenIn, tokenOut, amountOutDecimal, slippageBps) slot
returning { requiredInRaw, maxInRaw, priceImpactBps } (read-only).
Editing the Buy amount now debounces a swapExactOutQuote call and sources the
required input (shown in the Sell field), the price impact, and the slippage
ceiling from it — the exact figures come straight from the quote's raw integer
strings, so the preview matches execution and no reserve orientation happens
client-side. A retyped amount invalidates the quote up front.
SwapSummary's last row is generalised from a hardcoded "Min received" to a
direction-aware bound (boundLabel/boundText): "Min received" (min out) for
exact input, "Maximum sent" (max in) for exact output. SwapConfirmationSummary
is updated for the renamed property.
The Buy field remains preview-only — canSubmit is still sell-only, pending the
exact-output submit wiring. The now-orphaned DummySwapState pricing helpers are
left for a follow-up cleanup.
Wire the Sell direction of the swap card to the module's server-side quote
instead of the client-side DummySwapState estimate. AmmUiBackend gains a
swapExactInQuote(tokenIn, tokenOut, amountInDecimal, slippageBps) slot that
forwards to amm_module and returns { expectedOutRaw, minReceivedRaw,
priceImpactBps } (read-only, no wallet guard).
SwapCard debounces a swapExactInQuote call as the user types a Sell amount and
sources the expected output, min received, and price impact from it. The exact
figures shown (buy field, confirmation snapshot) and the submitted min_out come
straight from the quote's raw integer strings, so the preview can't drift from
execution and the client no longer orients reserves (fixes the #236 defAHex
bug) or recomputes min_out in double/BigInt. A retyped amount invalidates the
quote immediately and blocks submit until the re-quote lands.
The Buy direction is unchanged — still a local DummySwapState preview, pending
the exact-output wiring. resolvePool stays as the source of pool existence, the
fee row, and the Buy-side reserves.
After the amm_module refactor, this crate is linked only by the module (the
UI delegates to modules().amm_module and links nothing), so its home under
apps/amm/ and the name "client" were both misnomers: it's the AMM business
logic the module wraps, reached across an FFI boundary — the same relationship
logos_execution_zone has with wallet_ffi. Co-locate it with the module that
owns it and name it for that role.
The FFI surface is unchanged — the exported functions are already amm_* (not
amm_client_*) — so only the crate, directory, generated header, dylib, and
package names move. The module's call sites are untouched; it just includes the
renamed header.
- apps/amm/client → modules/amm/ffi (git-tracked rename; history preserved)
- crate amm_client → amm_ffi: package name, include/amm_ffi.h, libamm_ffi.dylib,
AMM_FFI_H guard, build.rs output path, tests/public_api.rs import
- workspace member path + Cargo.lock
- flake.nix: pname, -p, header-copy path, dylib install_name, packages.amm_ffi,
ammModuleOutputs externalLibInputs, DYLD wrapper
- modules/amm: metadata external_libraries, CMakeLists EXTERNAL_LIBS, impl
#include + comments, README, flake note
- apps/amm/flake.nix: drop the now-dead amm_client external-lib input (the UI
links no external lib of its own)
Resulting layout:
modules/amm/
src/ # C++ module (amm_module_impl.{h,cpp})
ffi/ # Rust crate amm_ffi (Cargo.toml, src/, include/amm_ffi.h)
The add-liquidity flow stamped a `new-position.v1` schema tag on every
request and response and validated it across all three layers — the QML
plugin, the amm_module core module, and the amm_client Rust crate. It was a
cross-version compatibility guard, but these artifacts always ship together,
so the contract is honored implicitly, and the swap view already works fine
without one. Dropping it makes the liquidity view consistent with swap and
removes a layer of ceremony.
- amm_client: remove PositionRequest.schema and the unsupported_schema check
in compute_quote; drop QuoteCommitment.schema (changes quoteHash, which is
internal-only) and every "schema" response stamp; delete the SCHEMA /
NEW_POSITION_SCHEMA constants and the public export.
- amm_module: remove the SCHEMA constant and its four response stamps.
- AmmUiBackend: remove its local NEW_POSITION_SCHEMA and the stamps in
loadingContext() / newPositionError().
- QML: drop the "schema" fields from the request/envelope builders and relax
the validity gates to check status / canSubmit instead (the sole check in
NewPositionFlow now guards on a missing `status`); strip the now-dead
schema fields from the liquidity QML test fixtures.
- Also removes the last stale comment references to the deleted *Runtime
classes.
Introduce modules/amm — the AMM business logic as a universal core Logos module,
consumed identically by the QML UI (via modules().amm_module) and headlessly
(logoscore call amm_module ...). The module is a thin transport adapter: the
domain math lives in the Rust amm_client crate (the transport-independent JSON
FFI), and the module sequences those pure ops with chain I/O delegated to the
logos_execution_zone wallet module. It reaches the same shared wallet instance
the UI opened (Basecamp loads core modules as singletons; standalone the
LogosAPI client cache dedups the connection), so it never opens a second wallet.
The module owns the full AMM surface — not just swaps:
- resolvePool / swapExactInput / tokenList (the swap path)
- newPositionContext / quoteNewPosition / submitNewPosition (add-liquidity)
apps/amm: delete the app-side orchestration (SwapRuntime, NewPositionRuntime,
AmmClient/BundledAmmClient) and the amm_client link. AmmUiBackend now owns only
wallet-session lifecycle and forwards every AMM slot to modules().amm_module.
The one wallet-keyset mutation add-liquidity needs — creating a fresh LP holding
— stays in the backend (via its wallet provider, keeping the account model and
on-disk storage coherent): the module returns "requires_fresh_lp" without
submitting, the backend creates the account and resubmits with its id.
flake.nix / CMakeLists / metadata: the module links the amm_client crate; the UI
links no external lib and depends on amm_module (injected into the UI builder's
flakeInputs so the dependency resolves).
- amounts/deadline declared nlohmann::json so the generated dispatch accepts a
JSON number (bare small ints on the CLI) or a string (exact u128 from the UI,
or a quote-wrapped big value on the CLI); JSON floats are rejected rather than
submit a silently-rounded amount.
- AMM_DEBUG-gated tracing for the swap path.
- Drop tests/cpp/NewPositionRuntimeTest.cpp with the class it covered
(module-level tests to follow).
- modules/amm/README.md: architecture, headless prerequisites, logoscore recipe.
The AMM host FFI was split across two crates with two ABI styles: the
typed-C `amm_client_ffi` (swap primitives, under programs/) and the
JSON/wire `amm_client` (new-position flow, under apps/). Fold both into a
single `amm_client` crate exposing one JSON C ABI, and delete
`programs/amm/client-ffi`.
Rust:
- Re-express the swap path as `api/swap.rs` operations on the existing
`call::<T>` dispatch — swap_pair, resolve_pool, swap_plan, program_id —
reusing `pair::derive_pair` (no more duplicated PDA derivation) and
`risc0_zkvm::serde` for the SwapExactInput words (the same encoding the
guest decodes). The account list and signer flags stay byte-identical
to the old typed path.
- Generate a single header (`include/amm_client.h`) covering all ops via
cbindgen; bump cbindgen 0.27 -> 0.28 for `#[unsafe(no_mangle)]` support.
C++:
- Extend the `AmmClient` wrapper with the four swap ops.
- Add `SwapRuntime` (mirrors `NewPositionRuntime`): reads accounts through
the wallet, drives the swap ops, submits the transaction.
- `AmmUiBackend` swap methods now delegate to `SwapRuntime`, dropping ~390
lines of typed-FFI and byte-twiddling. `program_id` becomes a JSON op,
and the swap clock is derived via `derive_pair` (clock_core::CLOCK_01)
instead of a hardcoded base58 literal — same account, verified.
networkSnapshot() rebuilt the new-position network context on every call —
deriving ammProgramId from $AMM_PROGRAM_BIN and resolving the $TOKENS_CONFIG
token ids, which run tokenList()'s remote account_id_from_base58 conversions.
It is called on the quote hot path (every keystroke) and, critically, from
inside runtime reply callbacks: after a create-pool submit, pool activation
runs refreshContext() from within a quoteNewPosition reply, so the nested
synchronous remote calls reentered the module connection and hung the reply.
refreshNewPositionContext never completed, contextLoading never cleared, and
the token selectors (gated on !contextLoading) stayed disabled — the view
became unusable after creating a pool.
$AMM_PROGRAM_BIN and $TOKENS_CONFIG are fixed for the process lifetime, so
resolve ammProgramId and the token ids once and cache them; networkSnapshot()
now returns the cached values with no per-call remote work. (Still gated to
"loading" until wallet state resolves, so the one-time resolve happens at
startup, not inside a callback.)
The create-pool / new-position flow carried its own network layer:
AMM_UI_NETWORK + AMM_UI_DEVNET_FILE (a devnet.json) or a bundled
config/networks.json supplied the AMM program id and token set, and a
JSON-RPC channel/checkpoint "identity probe" gated the flow to a verified
network. Main already exposes all of this the way the Swap view consumes it,
so collapse onto those sources instead of a parallel system:
- ammProgramId <- $AMM_PROGRAM_BIN (derived like swapExactInput's program id;
doubles as the quote's network fingerprint so a quote can't
be replayed against a different deployment)
- tokenIds <- $TOKENS_CONFIG (amm-tokens.json), same as the Swap picker
- sequencer <- the wallet config (already surfaced via syncWalletState)
networkSnapshot() builds the ActiveNetworkSnapshot from those; status is
"ready"/"config_missing", gated to "loading" until wallet state resolves so no
module reads happen during construction. The channel probe is gone — submit
needs no channelId (the wallet module supplies the channel via
submitPublicTransaction), so the whole verification apparatus was overhead.
Removes: AMM_UI_NETWORK / AMM_UI_DEVNET_FILE, devnet.json / networks.json, the
ActiveNetwork class (+ its test) and its QNetwork channel probe, and Qt6Network.
ActiveNetwork.h keeps only the ActiveNetworkSnapshot struct. Run command drops
the AMM_UI_* vars:
```
LEE_WALLET_HOME_DIR=… AMM_PROGRAM_BIN=… TOKENS_CONFIG=… nix run .#amm-ui
```
Keep wallet assets as token choices without automatically selecting a pair. Keep pool-probe amounts internal so active-pool quotes do not populate the form before user input.
Add a "Create Pool" flow to the AMM app that lets a user open a new
liquidity position — seeding a pool's initial liquidity — from token
selection and amount entry, through a confirmation dialog, to on-chain
submission.
- client crate (apps/amm/client): pure, testable protocol logic — account
decoding, pair/position modelling, and quote/plan computation — exposed to
the app over a C ABI (config/networks.json drives network selection).
- C++ runtime + backend: AmmClient, ActiveNetwork, and NewPositionRuntime,
wired into AmmUiBackend (new resolve/quote/submit slots).
- QML flow: NewPositionForm, NewPositionFlow state, NewPositionConfirmation-
Dialog, TokenSelectorModal, and reusable Amm* presentational components
(theme, surfaces, buttons) + AmountMath.js.
- tests: C++ (NewPositionRuntimeTest, ActiveNetworkTest) and QML
(tst_NewPositionForm, tst_LiquidityPage, tst_TokenAmountInput, …).
Turns the dummy-data AMM UI into a real client of the on-chain LEZ wallet.
Adds a hand-written ui_qml C++ backend (src/AmmUi*) over the core
logos_execution_zone module: create/open a local wallet, create and list
public/private accounts, and a navbar Connect / Connected + account-selector
+ Disconnect flow. Onboarding is password-only (no path picking) with a
per-app wallet at ~/.lee/amm-wallet (override: AMM_WALLET_HOME_DIR);
standalone gets its own wallet, Basecamp shares accounts via adopt-on-start.
Requires Nix with flakes; macOS also needs `sandbox = false` (the default).
The logos_execution_zone input is pinned to a module rev whose LEZ (lssa)
already includes the macOS Metal-build fix, so no `--override-input` is
needed — plain `nix run .` works:
cd apps/amm
nix run .
- create_new now returns the new wallet's BIP39 mnemonic (not an int status);
the app currently discards it, so the wallet can't yet be recovered. Surfacing
it in onboarding (+ restore_storage) is a follow-up.
- The wallet password is currently a no-op upstream (storage.rs: "TODO: use
password for storage encryption"); storage.json is plaintext. So Disconnect
is a UI-level lock and reconnect does not (cannot yet) re-prompt for it.
- wallet-ffi requires explicit config/storage paths; a *_default() FFI would
let the app drop its path handling.
- Bundled network config: connects to whatever WalletConfig::default() points
at; real testnet endpoints still TBD.
