Consolidate wallet account decoding and portfolio handling around the shared Rust IDL decoder. Simplify AMM wallet integration, remove obsolete caches and network plumbing, and cover account selection and live flows.
The Pools page shipped with a hardcoded four-pair sample. Replace it with a
config-driven "known pools" list, mirroring how the Swap token picker reads
TOKENS_CONFIG: the app loads a flat JSON array from the AMM_POOLS_CONFIG
environment variable and renders one row per entry. Adding pairs is a config
edit — no app change.
Pool discovery is an app concern, so the config is read in the backend
(AmmUiBackend::poolList, Qt JSON) rather than the amm_module — the module is
shedding app-specific view surface (tokenList/newPositionContext), so pools go
where tokens are heading, not where they are today. poolList() fails soft to an
empty list when AMM_POOLS_CONFIG is unset/unreadable/not an array, and skips
individual entries missing tokenA/tokenB/a numeric feeBps.
Each entry carries the display symbols (tokenA/tokenB), feeBps, and the on-chain
identifiers (poolId, tokenADefinitionId, tokenBDefinitionId) so a row can later
be resolved against chain state. PoolsPage takes injected backend/runtime and
loads via runtime.watch(backend.poolList()); the Repeater renders entries
generically.
The AMM testnet setup script now emits amm-pools.json from a POOL_SPECS array
(one line per seeded pool, currently the seeded TKA/TKB pool) and prints
AMM_POOLS_CONFIG in the launch instructions. Adds amm-pools.json.example, a
README section, and gitignores the runtime config files.
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)
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, …).
