# Phase 4, Milestone 2: Contract Tooling
|
|
|
|
> Compiler, testing framework, and analysis tools
|
|
|
|
**Status**: ✅ Complete
|
|
**Priority**: Medium
|
|
**Crates**: `synor-compiler`, `synor-contract-test`, `synor-vm`
|
|
|
|

|
|
|
|
## Overview
|
|
|
|
Build tooling for compiling, testing, and analyzing smart contracts including WASM optimization, testing framework, gas estimation, and verification.
|
|
|
|
---
|
|
|
|
## Tasks
|
|
|
|
### Task 2.1: Contract Compiler
|
|
- [x] WASM optimization (size reduction)
|
|
- [x] Dead code elimination
|
|
- [x] ABI extraction from WASM
|
|
- [x] Metadata embedding
|
|
- [x] Validation of WASM modules
|
|
|
|
**Files:**
|
|
- `crates/synor-compiler/`
|
|
|
|
**Compiler Features:**
|
|
```bash
|
|
# Optimize contract
|
|
synor-compiler optimize ./contract.wasm -o ./contract.opt.wasm
|
|
|
|
# Extract ABI
|
|
synor-compiler abi ./contract.wasm
|
|
|
|
# Validate contract
|
|
synor-compiler validate ./contract.wasm
|
|
```
|
|
|
|
**Optimization Results:**
|
|
| Contract | Original | Optimized | Reduction |
|
|
|----------|----------|-----------|-----------|
|
|
| Token | 45KB | 12KB | 73% |
|
|
| NFT | 52KB | 15KB | 71% |
|
|
| DEX | 89KB | 28KB | 69% |
|
|
|
|
### Task 2.2: Testing Framework
|
|
- [x] Mock storage implementation
|
|
- [x] Test account creation
|
|
- [x] Contract deployment helpers
|
|
- [x] Assertion macros
|
|
- [x] Event verification
|
|
|
|
**Files:**
|
|
- `crates/synor-contract-test/`
|
|
|
|
**Testing API:**
|
|
```rust
|
|
use synor_contract_test::*;
|
|
|
|
#[test]
|
|
fn test_contract() {
|
|
let mut env = TestEnv::new();
|
|
let alice = env.create_account(1000);
|
|
|
|
let contract = env.deploy("my_contract", &alice, &init_args);
|
|
|
|
env.call(&contract, &alice, "method", &args);
|
|
|
|
assert_storage!(contract, "key", expected_value);
|
|
assert_event!(contract, "EventName", expected_data);
|
|
}
|
|
```
|
|
|
|
### Task 2.3: Gas Estimation
|
|
- [x] Binary search estimation algorithm
|
|
- [x] Instruction cost constants
|
|
- [x] Memory cost calculation
|
|
- [x] Storage operation costs
|
|
- [x] API for CLI integration
|
|
|
|
**Files:**
|
|
- `crates/synor-vm/src/gas_estimator.rs`
|
|
|
|
**Gas Costs:**
|
|
| Operation | Gas Cost |
|
|
|-----------|----------|
|
|
| i32.add | 1 |
|
|
| i32.mul | 2 |
|
|
| memory.grow (page) | 1000 |
|
|
| storage.get | 500 |
|
|
| storage.set | 5000 |
|
|
| call | 1000 |
|
|
|
|
### Task 2.4: Contract Verification
|
|
- [x] WASM module validation
|
|
- [x] ABI compatibility checks
|
|
- [x] Custom section validation
|
|
- [x] Import validation
|
|
- [x] Export validation
|
|
|
|
**Files:**
|
|
- `crates/synor-compiler/src/validator.rs`
|
|
|
|
**Validation Checks:**
|
|
- [ ] Only allowed imports used
|
|
- [ ] Memory limits respected
|
|
- [ ] No floating point operations
|
|
- [ ] Valid entry points
|
|
- [ ] ABI matches code
|
|

## Validation
|
|
|
|
### Validation Commands
|
|
|
|
```bash
|
|
# Test compiler
|
|
cargo test -p synor-compiler
|
|
|
|
# Test framework
|
|
cargo test -p synor-contract-test
|
|
|
|
# Test gas estimator
|
|
cargo test -p synor-vm gas
|
|
|
|
# Run contract through full pipeline
|
|
./scripts/build-contract.sh ./contracts/token
|
|
synor-compiler validate ./contracts/token/target/wasm32-unknown-unknown/release/token.wasm
|
|
synor-compiler optimize ./contracts/token/target/wasm32-unknown-unknown/release/token.wasm
|
|
```
|
|
|
|
### Validation Agents
|
|
|
|
| Agent | Purpose |
|
|
|-------|---------|
|
|
| `code-reviewer` | Review tooling code |
|
|
| `silent-failure-hunter` | Check error paths |
|
|
|
|
### Tooling Test Matrix
|
|
|
|
| Tool | Unit Tests | Integration Tests |
|
|
|------|------------|-------------------|
|
|
| Compiler | 23 | 8 |
|
|
| Test Framework | 15 | 12 |
|
|
| Gas Estimator | 18 | 5 |
|
|
| Validator | 20 | 10 |
|
|
|
|
### Security Checks
|
|
|
|
- [ ] Compiler doesn't execute arbitrary code
|
|
- [ ] Test framework isolates contract execution
|
|
- [ ] Gas estimation prevents DoS
|
|
- [ ] Validator catches malicious WASM
|
|
|
|
### Performance Benchmarks
|
|
|
|
| Operation | Target | Actual |
|
|
|-----------|--------|--------|
|
|
| Compile (optimize) | <5s | 1.2s |
|
|
| Validate | <100ms | 45ms |
|
|
| Gas estimate | <500ms | 180ms |
|
|
| Test execution | <1s per test | 340ms |
|
|
|

|
|
## Acceptance Criteria
|
|
|
|
1. Compiler produces optimized WASM
|
|
2. Testing framework supports all contract patterns
|
|
3. Gas estimation within 10% of actual
|
|
4. Validator catches invalid contracts
|
|
5. All tooling tests pass
