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, …).
