-# WASM Module for Programmable Escrows
-
-This module provides WebAssembly (WASM) execution capabilities for programmable
-escrows on the XRP Ledger. When an escrow is finished, the WASM code runs to
-determine whether the escrow conditions are met, enabling custom programmable
-logic for escrow release conditions.
-
-For the full specification, see
-[XLS-0102: WASM VM](https://xls.xrpl.org/xls/XLS-0102-wasm-vm.html).
-
-## Architecture
-
-The module follows a layered architecture:
-
-```
-┌─────────────────────────────────────────────────────────────┐
-│                 WasmEngine (WasmVM.h)                       │

-└─────────────────────────────────────────────────────────────┘
-```
-
-### Key Components
-
-- **`WasmVM.h` / `detail/WasmVM.cpp`** - High-level facade providing:
-  - `WasmEngine` singleton that wraps the underlying WASM interpreter
-  - `runEscrowWasm()` - Execute WASM code for escrow finish
-  - `preflightEscrowWasm()` - Validate WASM code during preflight
-  - `createWasmImport()` - Register all host functions
-
-- **`WasmiVM.h` / `detail/WasmiVM.cpp`** - Low-level integration with the
-  [wasmi](https://github.com/wasmi-labs/wasmi) WebAssembly interpreter:
-  - `WasmiEngine` - Manages WASM modules, instances, and execution
-  - Memory management and gas metering
-  - Function invocation and result handling
-
-- **`HostFunc.h`** - Abstract `HostFunctions` base class defining the interface
-  for all callable host functions. Each method returns
-  `std::expected<T, HostFunctionError>`.
-
-- **`HostFuncImpl.h` / `detail/HostFuncImpl*.cpp`** - Concrete
-  `WasmHostFunctionsImpl` class that implements host functions with access to
-  `ApplyContext` for ledger state queries. Implementation split across files:
-  - `HostFuncImpl.cpp` - Core utilities (updateData, checkSignature, etc.)
-  - `HostFuncImplFloat.cpp` - Float/number arithmetic operations
-  - `HostFuncImplGetter.cpp` - Field access (transaction, ledger objects)
-  - `HostFuncImplKeylet.cpp` - Keylet construction functions
-  - `HostFuncImplLedgerHeader.cpp` - Ledger header info access
-  - `HostFuncImplNFT.cpp` - NFT-related queries
-  - `HostFuncImplTrace.cpp` - Debugging/tracing functions
-
-- **`HostFuncWrapper.h` / `detail/HostFuncWrapper.cpp`** - C-style wrapper
-  functions that bridge WASM calls to C++ `HostFunctions` methods. Each host
-  function has:
-  - A `_proto` type alias defining the function signature
-  - A `_wrap` function that extracts parameters and calls the implementation
-
-- **`ParamsHelper.h`** - Utilities for WASM parameter handling:
-  - `WASM_IMPORT_FUNC` / `WASM_IMPORT_FUNC2` macros for registration
-  - `wasmParams()` helper for building parameter vectors
-  - Type conversion between WASM and C++ types
-
-## Host Functions
-
-Host functions allow WASM code to interact with the XRP Ledger. They are
-organized into categories:
-
-- **Ledger Information** - Access ledger sequence, timestamps, hashes, fees
-- **Transaction & Ledger Object Access** - Read fields from the transaction
-  and ledger objects (including the current escrow object)
-- **Keylet Construction** - Build keylets to look up various ledger object types
-- **Cryptography** - Signature verification and hashing
-- **Float Arithmetic** - Mathematical operations for amount calculations
-- **NFT Operations** - Query NFT properties
-- **Tracing/Debugging** - Log messages for debugging
-
-For the complete list of available host functions, their WASM names, and gas
-costs, see the [XLS-0102 specification](https://xls.xrpl.org/xls/XLS-0102-wasm-vm.html)
-or `detail/WasmVM.cpp` where they are registered via `WASM_IMPORT_FUNC2` macros.
-For method signatures, see `HostFunc.h`.
-
-## Gas Model
-
-Each host function has an associated gas cost. The gas cost is specified when
-registering the function in `detail/WasmVM.cpp`:
-
-```cpp
-WASM_IMPORT_FUNC2(i, getLedgerSqn, "get_ledger_sqn", hfs, 60);
-//                                                        ^^ gas cost
-```
-
-WASM execution is metered, and if the gas limit is exceeded, execution fails.
-
-## Entry Point
-
-The WASM module must export a function with the name defined by
-`escrowFunctionName` (currently `"escrow_finish"`). This function:
-
-- Takes no parameters (or parameters passed via host function calls)
-- Returns an `int32_t`:
-  - `1` (or positive): Escrow conditions are met, allow finish
-  - `0` (or negative): Escrow conditions are not met, reject finish
-
-## Adding a New Host Function
-
-To add a new host function, follow these steps:
-
-### 1. Add to HostFunc.h (Base Class)
-
-Add a virtual method declaration with a default implementation that returns an
-error:
-
-```cpp
-virtual std::expected<ReturnType, HostFunctionError>
-myNewFunction(ParamType1 param1, ParamType2 param2)
-{
-    return std::unexpected(HostFunctionError::INTERNAL);
-}
-```
-
-### 2. Add to HostFuncImpl.h (Declaration)
-
-Add the method override declaration in `WasmHostFunctionsImpl`:
-
-```cpp
-std::expected<ReturnType, HostFunctionError>
-myNewFunction(ParamType1 param1, ParamType2 param2) override;
-```
-
-### 3. Implement in detail/HostFuncImpl\*.cpp
-
-Add the implementation in the appropriate file:
-
-```cpp
-std::expected<ReturnType, HostFunctionError>
-WasmHostFunctionsImpl::myNewFunction(ParamType1 param1, ParamType2 param2)
-{
-    // Implementation using ctx (ApplyContext) for ledger access
-    return result;
-}
-```
-
-### 4. Add Wrapper to HostFuncWrapper.h
-
-Add the prototype and wrapper declaration:
-
-```cpp
-using myNewFunction_proto = int32_t(uint8_t const*, int32_t, ...);
-wasm_trap_t*
-myNewFunction_wrap(void* env, wasm_val_vec_t const* params, wasm_val_vec_t* results);
-```
-
-### 5. Implement Wrapper in detail/HostFuncWrapper.cpp
-
-Implement the C-style wrapper that bridges WASM to C++:
-
-```cpp
-wasm_trap_t*
-myNewFunction_wrap(void* env, wasm_val_vec_t const* params, wasm_val_vec_t* results)
-{
-    // Extract parameters from params
-    // Call hfs->myNewFunction(...)
-    // Set results and return
-}
-```
-
-### 6. Register in WasmVM.cpp
-
-Add the function registration in `setCommonHostFunctions()` or
-`createWasmImport()`:
-
-```cpp
-WASM_IMPORT_FUNC2(i, myNewFunction, "my_new_function", hfs, 100);
-//                                   ^^ WASM name       ^^ gas cost
-```
-
-> [!IMPORTANT]
-> New host functions MUST be amendment-gated in `WasmVM.cpp`.
-> Wrap the registration in an amendment check to ensure the function is only
-> available after the corresponding amendment is enabled on the network.
