Add .cargo/config.toml setting CFLAGS_riscv32im_risc0_zkvm_elf to
"-march=rv32im -nostdlib". This prevents cc-rs from injecting
macOS-specific flags (-arch arm64, -mmacosx-version-min) into the
riscv32-unknown-elf-gcc cross-compiler when building C dependencies
(e.g. ring) for the guest target, which causes build failures on
macOS 26 Tahoe.
- Updated `nssa_core` and `spel-framework` dependencies to their respective release candidates in `Cargo.toml` and `Cargo.lock` files for `amm`, `ata`, and `token` modules.
- Enhanced the `new_definition` function in `amm/src/new_definition.rs` to include new claim logic and updated PDA seed calculations.
- Modified tests in `integration_tests/tests/amm.rs`, `integration_tests/tests/ata.rs`, and `integration_tests/tests/token.rs` to accommodate changes in transaction handling and account initialization.
- Refactored account initialization logic in `ata/src/create.rs` and `token/src/initialize.rs` to include authorization claims.
- Updated various functions in `token/src/mint.rs`, `token/src/new_definition.rs`, and `token/src/transfer.rs` to utilize the new claim system for account states.
- Adjusted the IDL generation tool to use the latest version of `spel-framework-core`.
Implement Uniswap V2-style fees-in-reserves: the full swap_amount_in is
deposited into the reserve (growing k = reserve_a * reserve_b), while
only the fee-adjusted effective_amount_in is used to compute the output
amount. This means LPs earn fees proportionally on every removal via
k-growth rather than through a separate vault surplus.
- swap_logic: add fee_bps parameter; compute effective_amount_in for
output formula only; return full swap_amount_in as the reserve deposit
- Fix all integration test fixture values to match fees-in-reserves math
- Remove dead-code vault_a/b_init_zero helpers from unit tests
Remove the `active: bool` field from `PoolDefinition` and replace it with an
implicit invariant: a pool is considered active when
`liquidity_pool_supply >= MINIMUM_LIQUIDITY`.
BREAKING CHANGE: `PoolDefinition` Borsh serialization format has changed.
Existing on-chain pool accounts encoded with the `active` field are
incompatible with this version.
Closes#25
Move IDL files to artifacts/ and add a convention-based CI check that
discovers all programs via */methods/guest/src/bin/*.rs and fails if
any program is missing its IDL or has one that is out of date.
- accept a supported fee tier in pool creation
- store fee tiers in AMM pool state and validate them
- update AMM tests and IDL for the new pool creation argument
Renames the Swap instruction and its guest handler to SwapExactInput to
distinguish it from the newly added SwapExactOutput, and to make the
intent of each variant explicit at the call site.
BREAKING CHANGE: the Swap instruction variant and swap() function are
renamed to SwapExactInput and swap_exact_input(). Callers must update
instruction construction and any IDL-generated bindings.
Adds SwapExactOutput to the AMM, allowing callers to specify the exact
desired output amount while the protocol computes the required input
(ceiling division to prevent rounding in the protocol's favour).
The swap-exact-output success tests now use a dedicated small-pool
fixture (reserve_a=1_000, reserve_b=500) rather than the shared
pool_definition_init, which had its reserves bumped to 5_000/2_500 in a
later commit to satisfy the MINIMUM_LIQUIDITY invariant introduced for
new_definition. Using a dedicated fixture keeps each test self-contained
and avoids hardcoded expected values silently breaking when shared
baselines change.
Adds a new `SyncReserves` instruction that updates a pool's recorded
reserves to match the actual vault balances. This allows the pool to
absorb donations (direct token transfers to vaults) without breaking
the invariant — only upward adjustments are permitted; vaults may
not be under-collateralized relative to reserves.
Vault reading helpers (`read_fungible_holding`,
`read_vault_fungible_balances`) are implemented in `amm_core` so they
can be shared across instructions without crossing crate boundaries.
Permanently lock `MINIMUM_LIQUIDITY` (1_000) LP tokens in a dedicated
LP-lock holding PDA on pool creation, following the Uniswap v2 "dead
shares" pattern. The pool creator receives `initial_lp - MINIMUM_LIQUIDITY`
tokens instead of the full initial_lp amount.
Adds `compute_lp_lock_holding_pda` and `LP_LOCK_HOLDING_PDA_SEED` to
amm_core, updates new_definition to emit two sequential chained calls
(create LP definition + lock holding, then mint user share), and adjusts
remove liquidity to account for the permanently locked floor.
BREAKING CHANGE: NewDefinition instruction requires an additional LP-lock
holding account derived via `compute_lp_lock_holding_pda(amm_program_id, pool_id)`.
