Key changes: - Support for both execute() overloads (with/without deadline) - Decoders for V2/V3 swaps, Permit2, PayPortion, UnwrapWeth, and other commands - Manual ABI decoding for V2SwapExactIn to work around Alloy decoder limitations - UniversalRouterContractVisualizer registered in visualizer registry - Added EthereumVisualizerRegistry to converter for protocol-specific visualization - Refactored to use UniswapConfig::weth_address instead of WellKnownAddresses - All documentation references official Uniswap technical docs Transactions that previously showed raw hex now display structured command breakdowns with token symbols, amounts, and operation details. All 91 tests passing.

Type Safety First +Use the `sol!` macro to generate type-safe decoders. Avoid manual byte parsing. + +### 2. Registry as Single Source of Truth +All token symbols and decimals come from `ContractRegistry`. This ensures consistency and allows wallets to customize metadata. + +### 3. Graceful Error Handling +Always handle decode failures by returning a TextV2 field with the hex input. This gives users visibility into what failed. + +### 4. Clean, Human-Readable Output +Format amounts with proper decimals and symbols. Make the transaction intent clear. + +### 5. No ASCII Characters in Strings +Use `>=` and `<=` instead of non-ASCII characters like `≥` and `≤` for terminal compatibility. + +## Reusable Utilities + +### WellKnownAddresses + +For contracts like WETH that don't need registry lookups: + +```rust +use crate::utils::address_utils::WellKnownAddresses; + +let weth_address = WellKnownAddresses::weth(chain_id)?; +let permit2_address = WellKnownAddresses::permit2(); +``` + +### Error Fields + +Create consistent error fields: + +```rust +SignablePayloadField::TextV2 { + common: SignablePayloadFieldCommon { + fallback_text: format!("{}: 0x{}", operation_name, hex::encode(bytes)), + label: operation_name.to_string(), + }, + text_v2: SignablePayloadFieldTextV2 { + text: "Failed to decode parameters".to_string(), + }, +} +``` + +## Adding Support for Aave + +When you're ready to add Aave support, follow this pattern: + +```rust +// 1. Define Aave structs using sol! +sol! { + struct DepositParams { + address asset; + uint256 amount; + address onBehalfOf; + } + + struct BorrowParams { + address asset; + uint256 amount; + uint256 interestRateMode; + address onBehalfOf; + } +} + +// 2. Create decoder functions (same pattern as Uniswap) +fn decode_deposit(bytes: &[u8], chain_id: u64, registry: Option<&ContractRegistry>) -> SignablePayloadField { + // ... follows the same pattern ... +} + +// 3. Add to main match statement +match aave_operation { + AaveOp::Deposit => decode_deposit(bytes, chain_id, registry), + AaveOp::Borrow => decode_borrow(bytes, chain_id, registry), + // ... +} +``` + +## Summary + +The pattern is simple and scales: +1. Define structs with `sol!` +2. Create decoder function (20-40 lines) +3. Add to match statement +4.

The visualizer must first decode this outer call, then iterate through the `calls` array. For each `Call` in the array, it must: + +1. Read the `selector`. +2. Match the `selector` to a known function. +3. Decode the `data` field using the corresponding function's ABI. + +### Contract Registry for Context + +The `ContractRegistry` is crucial for providing context, such as token symbols and decimals. All visualizers should query the registry to enrich the output. + +--- + +## How to Add a New Command + +To add support for a new command (e.g., `blueSupply`): + +1. **`contracts/bundler.rs`**: + + - Add the function signature and any required structs to the `sol!` macro block. + ```rust + // ... existing sol! macro + function blueSupply(address market, uint256 assets, address onBehalf, bytes data) external; + // ... + ``` + - Add a new `const` for the selector. + ```rust + // ... + const BLUE_SUPPLY_SELECTOR: [u8; 4] = selector!("blueSupply(address,uint256,address,bytes)"); + // ... + ``` + - Add a new match arm in `decode_nested_call`. + ```rust + // ... + match selector { + // ... + BLUE_SUPPLY_SELECTOR => self.decode_blue_supply(registry, &call.data), + _ => Ok(unhandled_field(call)), + } + // ... + ``` + - Implement the `decode_blue_supply` function. This function should decode the parameters and return a `SignablePayloadField`. + ```rust + fn decode_blue_supply(...) -> Result { + // 1. Decode data using sol! struct: blueSupplyCall::decode_single(&data, true)? + // 2. Look up token symbols in registry. + // 3. Format amounts. + // 4. Return a TextV2 or PreviewLayout field. + } + ``` + +2. **`tests` in `contracts/bundler.rs`**: + + - Add a unit test for the new `decode_blue_supply` function with sample data. + - If possible, add the new command to the `test_visualize_multicall_real_transaction` test or create a new integration test. + +3. **`IMPLEMENTATION_STATUS.md` (This file)**: + - Move the command from the "⏳" section to the "✅" section. + - Update the status and add implementation notes. + +--- + +_Document Version 1.0_ +_Last Updated: 2025-11-16_ +_Status: Initial implementation with three core bundler commands._ diff --git a/src/chain_parsers/visualsign-ethereum/src/protocols/morpho/config.rs b/src/chain_parsers/visualsign-ethereum/src/protocols/morpho/config.rs new file mode 100644 index 00000000..f2a96b62 --- /dev/null +++ b/src/chain_parsers/visualsign-ethereum/src/protocols/morpho/config.rs @@ -0,0 +1,66 @@ +use crate::registry::{ContractRegistry, ContractType};

Introduction + +Welcome! This workshop will guide you through the process of adding a new protocol decoder to the VisualSign parser. VisualSign's power comes from its ability to translate complex, hexadecimal transaction data into a human-readable format. By the end of this session, you will have the knowledge and tools to extend VisualSign to support any EVM-based protocol. + +Our case study will be the **Morpho Bundler**, a contract that batches multiple operations into a single transaction. + +## 2. Before You Code: The Art of the "One-Shot" Spec + +The most common pitfall in software development is a poorly defined task. A vague request leads to a cycle of exploration, rework, and refinement. To avoid this, we advocate for creating a "one-shot" specification before writing a single line of code. + +The goal of a "one-shot" spec is to provide a developer with all the necessary information to complete a feature correctly in a single pass. It acts as a mission brief, a blueprint, and a definition of done, all in one. + +### Anatomy of a "One-Shot" Spec + +A perfect spec for a new protocol decoder should contain these seven elements: + +1. **High-Level Goal**: A single, clear sentence defining the objective. +2. **Project Context & Precedent**: Point to existing code that should be used as a template. This ensures architectural consistency. +3. **Target Contract & Transaction**: Provide the specific contract address, the relevant Solidity ABI, and a real-world raw transaction hex to serve as the primary test case. +4. **Core Logic Requirements**: Break down the decoding steps. How is the transaction identified? How are nested data structures handled? +5. **Detailed Output Specification**: A visual mock-up of the desired final output. This is the most critical part, as it removes all ambiguity about what "done" looks like. +6. **File Structure & Naming**: Specify the exact directory and file names to be created. +7. **Documentation Requirements**: State the need for documentation, like an `IMPLEMENTATION_STATUS.md` file, and provide a template. + +## 3. Case Study: The Morpho Bundler Mission Brief + +Here is the "one-shot" spec we could have used to implement the Morpho decoder. Each protocol may have unique quirks but if you're using something without too much assembly and quirks, this might work most of the way to get you started. + +--- + +**Subject: Implement VisualSign Decoder for Morpho BundlerV3** + +**1. High-Level Goal** +Create a visualizer that decodes a `multicall` to the Morpho Bundler, displaying each of the nested operations in a human-readable format. + +**2. Project Context & Precedent** +Please follow the existing architectural patterns outlined in `src/chain_parsers/visualsign-ethereum/DECODER_GUIDE.md`. The implementation should mirror the structure of the Uniswap protocol found in `src/chain_parsers/visualsign-ethereum/src/protocols/uniswap/`. + +**3. Target Contract & Transaction** +* **Contract Address**: `0x6566194141eefa99Af43Bb5Aa71460Ca2Dc90245` +* **Example Raw Transaction**: `0x02f9...da44c0` Full unsigned hex +* **Relevant ABIs**: + ```solidity + // For use with the sol! macro + struct Call { address target; bytes data; /* ... */ } + function multicall(Call[] calldata calls) external; + // Nested call ABIs + function permit(address owner, address spender, uint256 value, uint256 deadline, bytes signature) external; + function erc20TransferFrom(address token, address from, uint256 amount) external; + function erc4626Deposit(address vault, uint256 assets, uint256 minShares, address receiver) external; + ``` + +**4. Core Logic Requirements** +* The visualizer should trigger for transactions sent to the BundlerV3 address with the `multicall` selector (`0x374f435d`). +* The main `visualize_multicall` function should decode the `Call[]` array. +* It should then loop through each `Call` and use a `match` statement on the first 4 bytes of `call.data` (the selector) to delegate to a specific decoding function. +* Use the `ContractRegistry` to resolve token addresses to symbols and format amounts using the correct decimals. + +**5. Detailed Output Specification** +The final output should be structured as follows, using `ListLayout` and `PreviewLayout`: +``` +Morpho Bundler + Title: Morpho Bundler Multicall + Detail: 3 operation(s) + 📖 Expanded View: + ├─ Permit: Permit 1.000000 USDC to 0x4a6c... (expires: ...) + ├─ Transfer From: Transfer 1.000000 USDC from 0x4a6c... + └─ Vault Deposit: Deposit 1000000 assets into 0xbeef... vault +``` +*Note: The expanded view for each item should show all parameters, and if a token symbol is not found, display only the address.* + +**6. File Structure & Naming** +Create the following structure: +`src/chain_parsers/visualsign-ethereum/src/protocols/morpho/` +├── `mod.rs` +├── `config.rs` +└── `contracts/` + ├── `mod.rs` + └── `bundler.rs` + +**7. Documentation** +After implementation, create an `IMPLEMENTATION_STATUS.md` file inside `protocols/morpho/`, following the format of `protocols/uniswap/IMPLEMENTATION_STATUS.md`. + +--- + +## 4. Step-by-Step Implementation Guide + +Now, let's walk through how to turn that spec into working code. + +### Step 1: Set Up the File Structure + +As specified, create the directory and empty files. This provides the skeleton for our module. + +```sh +mkdir -p src/chain_parsers/visualsign-ethereum/src/protocols/morpho/contracts +touch src/chain_parsers/visualsign-ethereum/src/protocols/morpho/{mod.rs,config.rs} +touch src/chain_parsers/visualsign-ethereum/src/protocols/morpho/contracts/{mod.rs,bundler.rs} +``` + +### Step 2: Configure the Protocol (`config.rs`) + +Define a new `struct` for the contract and implement the `ContractType` trait. Then, create a config struct to hold the address and registration logic. + +```rust +// In src/chain_parsers/visualsign-ethereum/src/protocols/morpho/config.rs + +// 1. Define the contract type +pub struct Bundler3Contract; +impl ContractType for Bundler3Contract { /* ... */ } + +// 2. Define the config +pub struct MorphoConfig { /* ... */ } +impl MorphoConfig { + // 3. Add address and registration logic + pub fn bundler3_address() -> Address { ... } + pub fn register_contracts(registry: &mut ContractRegistry) { ... } +} +``` + +### Step 3: Implement the Core Logic (`contracts/bundler.rs`) + +This is where the main decoding happens. + +1. **Define ABIs with `sol!`**: Use the `sol!` macro from `alloy-sol-types` to create Rust types from the Solidity interfaces in the spec. +2. **Create the Visualizer Struct**: `pub struct BundlerVisualizer;` +3. **Implement the Main Entry Point**: Create `visualize_multicall`, which decodes the outer `multicall` and gets the array of `Call` structs. +4. **Implement the Dispatcher**: Create a `decode_nested_call` helper. This function takes a `Call` struct, `match`es on its `selector`, and calls the appropriate decoder for the nested operation. +5. **Implement Individual Decoders**: For each nested operation (`permit`, `transfer`, `deposit`), create a function that decodes its specific parameters, queries the `ContractRegistry` for token info, and formats the data into a `SignablePayloadField` (like `TextV2` or `PreviewLayout`). + +### Step 4: Integrate the Protocol + +Now, plug the new module into the application. + +1. **`src/chain_parsers/visualsign-ethereum/src/protocols/mod.rs`**: + * Declare the new module: `pub mod morpho;` + * Call its registration function: `morpho::register(registry);` +2. **`src/chain_parsers/visualsign-ethereum/src/lib.rs`**: + * In the main `visualize_ethereum_transaction` function, add logic to detect if the transaction is for the Morpho Bundler. If it is, instantiate `BundlerVisualizer` and call `visualize_multicall`. + +### Step 5: Test Your Implementation + +Use the raw transaction from the spec to create tests. + +* **Unit Tests**: Write tests for each individual decoder function (e.g., `test_decode_permit`). +* **Integration Test**: Write a test for the top-level `visualize_multicall` function using the full, real-world transaction data. This ensures all parts work together correctly. +* Run tests with `cargo test -p visualsign-ethereum`. + +### Step 6: Document Your Work + +Finally, create the `IMPLEMENTATION_STATUS.md` file as requested. This document is vital for future maintainers. It should clearly state: +* What is implemented (✅). +* What is not yet implemented (⏳). +* A guide on how to add new commands, so the next developer can follow your pattern. + +## 5. Conclusion + +By following this structured approach—starting with a detailed spec and moving through implementation, integration, testing, and documentation—you can efficiently and accurately extend VisualSign with new protocol decoders. This process not only ensures correctness but also promotes a clean, maintainable, and consistent codebase. + +Happy coding! From ad11418c20b49a193863a710b38f3eb2e934b1a8 Mon Sep 17 00:00:00 2001 From: Prasanna Gautam Date: Mon, 17 Nov 2025 16:55:47 +0000 Subject: [PATCH 16/20] fix(ethereum): Fix V3 Swap Exact In decoding with manual ABI parsing Replace sol! macro decoder with manual ABI decoding for V3SwapExactInputParams. The sol! macro's abi_decode() cannot handle raw calldata bytes from the Universal Router's inputs array, which contain offset pointers to dynamic fields. Manual decoding: - Reads fixed-size fields (amountIn, amountOutMinimum) from known byte offsets - Follows offset pointers to parse dynamic bytes path field - Extracts token addresses and fee from path data - Properly formats output with token symbols and decimals This fixes V3 Swap Exact In commands that were previously showing "Failed to decode parameters". They now display complete swap details including amounts, tokens, and fees.

00:00:00 2001 From: Prasanna Gautam Date: Mon, 17 Nov 2025 17:28:17 +0000 Subject: [PATCH 17/20] refactor(ethereum): Improve V3 Swap decoding with cleaner ABI parsing pattern Replace manual byte slicing with SolType::abi_decode_params for better code organization and maintainability. Apply the same pattern to both V3SwapExactIn and V3SwapExactOut decoders. Changes: - Use abi_decode_params for proper ABI decoding instead of manual offsets - Define parameter types as tuples: (Address, U256, U256, Bytes, bool) - Remove ~70 lines of manual byte manipulation code - Add comments explaining parameter structures and validation steps - Fix ambiguous method calls by explicitly specifying trait implementations - Improve error handling consistency across all decoders Benefits: - More maintainable: Uses standard Alloy patterns - More readable: Clear type definitions, self-documenting code - More robust: Proper ABI decoding validated by the compiler - Easier to extend: Same pattern for future swap decoders Testing: - All 102 Ethereum unit tests pass - V3 Swap Exact In/Out commands decode correctly - Transaction parsing shows complete swap details with amounts, tokens, fees Co-Authored-By: Claude --- .../uniswap/contracts/universal_router.rs | 135 ++++++++---------- 1 file changed, 58 insertions(+), 77 deletions(-) diff --git
