+   git checkout -b fix/issue-description
+   ```
+
+2. **Make your changes:**
+   - Write clear, documented code
+   - Follow the coding standards below
+   - Add tests for new functionality
+
+3. **Test thoroughly:**
+   ```bash
+   # Run all tests
+   forge test
+
+   # Run with gas reporting
+   forge test --gas-report
+
+   # Run specific test file
+   forge test --match-path test/AgentVault.t.sol
+   ```
+
+4. **Format your code:**
+   ```bash
+   forge fmt
+   ```
+
+5. **Commit with clear messages:**
+   ```bash
+   git commit -m "feat: add AgentVault withdrawal limits
+   
+   - Implements daily withdrawal caps per agent
+   - Adds emergency pause functionality
+   - Includes comprehensive test coverage"
+   ```
+
+6. **Push and create PR:**
+   ```bash
+   git push origin feature/your-feature-name
+   ```
+
+## Coding Standards
+
+### Solidity
+
+- **Version:** Use Solidity `^0.8.24` (as specified in `foundry.toml`)
+- **Style:** Follow the [Foundry formatter configuration](foundry.toml)
+- **Line length:** Maximum 120 characters
+- **Comments:** Use NatSpec format for all public/external functions
+
+```solidity
+/// @notice Deposits funds into the agent's vault
+/// @param amount The amount to deposit in wei
+/// @return success Whether the deposit succeeded
+/// @dev Emits a Deposit event on success
+function deposit(uint256 amount) external returns (bool success) {
+    // Implementation
+}
+```
+
+### Naming Conventions
+
+- Contracts: `PascalCase` (e.g., `AgentVault`, `AgentRegistry`)
+- Functions: `camelCase` (e.g., `deposit`, `withdraw`)
+- Constants: `UPPER_SNAKE_CASE` (e.g., `MAX_DEPOSIT`)
+- Events: `PascalCase` with past tense (e.g., `DepositMade`, `AgentRegistered`)
+- Errors: `PascalCase` with descriptive names (e.g., `InsufficientBalance`, `UnauthorizedOperator`)
+
+### Code Organization
+
+Order of elements in contracts:
+1. Type declarations (enums, structs)
+2. State variables
+3. Events
+4. Errors
+5. Modifiers
+6. Constructor
+7. External functions
+8. Public functions
+9. Internal functions
+10. Private functions
+
+## Testing Requirements
+
+All contributions must include comprehensive tests:
+
+### Test Coverage
+
+- **Minimum 90% line coverage** for new contracts
+- **All public/external functions** must have tests
+- **Edge cases** must be covered (zero values, max values, reverts)
+- **Fuzz tests** where applicable (see `foundry.toml` config)
+
+### Test Structure
+
+```solidity
+contract AgentVaultTest is Test {
+    AgentVault vault;
+    address agent;
+    address operator;
+
+    function setUp() public {
+        // Deploy contracts and set up state
+    }
+
+    function test_Deposit() public {
+        // Test normal operation
+    }
+
+    function test_Deposit_RevertWhen_ZeroAmount() public {
+        // Test edge case / revert
+    }
+
+    function testFuzz_Deposit(uint256 amount) public {
+        // Fuzz test with random inputs
+    }
+}
+```
+
+### Running Tests
+
+```bash
+# All tests
+forge test
+
+# With verbosity
+forge test -vv
+
+# With gas report
+forge test --gas-report
+
+# Specific test
+forge test --match-test test_Deposit
+
+# Fuzz tests only
+forge test --match-contract Fuzz
+```
+
+## Security Considerations
+
+This project handles real funds on Base mainnet. Security is paramount:
+
+### Before Submitting
+
+- [ ] Reentrancy protection checked (use `nonReentrant` where needed)
+- [ ] Integer overflow/underflow handled (Solidity 0.8+ helps)
+- [ ] Access controls implemented (owner, roles, or custom)
+- [ ] Emergency pause functionality considered
+- [ ] Events emitted for state changes
+- [ ] No hardcoded secrets or private keys
+
+### Security Review Process
+
+1. All PRs undergo automated testing
+2. New contracts require security review
+3. Changes to financial logic require additional scrutiny
+4. Consider requesting audit for significant changes
+
+### Vulnerability Disclosure
+
+If you discover a security vulnerability:
+
+1. **DO NOT** open a public issue
+2. Email security@nexusweb3.dev with details
+3. Allow reasonable time for response before disclosure
+4. Follow responsible disclosure practices
+
+## Areas for Contribution
+
+### High Priority
+
+- **New protocol implementations** (see roadmap for planned protocols 31-40)
+- **Integration adapters** for DeFi protocols (Aave, Compound, Uniswap, etc.)
+- **Gas optimization** for high-frequency operations
+- **Cross-chain bridges** to other L2s
+
+### Medium Priority
+
+- **Documentation improvements** (tutorials, examples, diagrams)
+- **Developer tooling** (SDKs, CLI tools, monitoring)
+- **Test coverage** expansion for edge cases
+- **Frontend examples** for protocol interactions
+
+### Good First Issues
+
+- Fix typos in documentation
+- Add missing NatSpec comments
+- Improve error messages for better UX
+- Add integration tests for existing protocols
+- Create example scripts for common operations
+
+## Protocol Categories
+
+Our 30 protocols are organized into three layers:
+
+### Financial Layer (Protocols 1-10)
+AgentVault, AgentRegistry, AgentEscrow, AgentYield, AgentInsurance, AgentTreasury, AgentPayment, AgentSwap, AgentLending, AgentStaking
+
+### Operational Layer (Protocols 11-20)
+AgentMarket, AgentBounty, AgentMilestone, AgentReferral, AgentCollective, AgentGovernance, AgentOracle, AgentMessaging, AgentLicense, AgentAuditLog
+
+### Safety Layer (Protocols 21-30)
+AgentKillSwitch, AgentKYA, AgentInsights, AgentBridge, AgentLaunchpad, AgentAuction, AgentInsolvency, AgentRecovery, AgentDispute, AgentReputation
+
+When contributing, specify which protocol(s) your changes affect.
