+# Ethers to Alloy Migration Status
+
+## ✅ **Completed Migration**
+
+### **Core Infrastructure**
+- ✅ **Dependencies**: Updated all `Cargo.toml` files to use `alloy = { version = "1.0", features = ["full"] }`
+- ✅ **Nix Configuration**: Updated `flake.nix` to use latest tools and Rust toolchain
+- ✅ **Provider Architecture**: Migrated `roles.rs` to use alloy's `RootProvider` with explicit address management
+- ✅ **Core Types**: Updated `level.rs` trait definitions to use alloy types
+
+### **Contract ABIs Converted (9/24)**
+All converted from hundreds of lines of ethers-generated code to clean `sol!` macros:
+
+1. ✅ **Fallback** (`ctf/src/abi/fallback.rs`) - 15 lines (was 532 lines)
+2. ✅ **Fallout** (`ctf/src/abi/fallout.rs`) - 12 lines  
+3. ✅ **CoinFlip** (`ctf/src/abi/coin_flip.rs`) - 12 lines
+4. ✅ **Telephone** (`ctf/src/abi/telephone.rs`) - 10 lines
+5. ✅ **Token** (`ctf/src/abi/token.rs`) - 12 lines
+6. ✅ **Delegate** (`ctf/src/abi/delegate.rs`) - 10 lines
+7. ✅ **Delegation** (`ctf/src/abi/delegation.rs`) - 11 lines
+8. ✅ **Force** (`ctf/src/abi/force.rs`) - 8 lines
+9. ✅ **Vault** (`ctf/src/abi/vault.rs`) - 11 lines
+10. ✅ **King** (`ctf/src/abi/king.rs`) - 12 lines
+
+### **Level Implementations Migrated (9/23)**
+1. ✅ **Level 01**: Fallback (`ctf/src/ethernaut/lvl01_fallback.rs`)
+2. ✅ **Level 02**: Fallout (`ctf/src/ethernaut/lvl02_fallout.rs`)
+3. ✅ **Level 03**: Coin Flip (`ctf/src/ethernaut/lvl03_coin_flip.rs`)
+4. ✅ **Level 04**: Telephone (`ctf/src/ethernaut/lvl04_telephone.rs`)
+5. ✅ **Level 05**: Token (`ctf/src/ethernaut/lvl05_token.rs`)
+6. ✅ **Level 06**: Delegate (`ctf/src/ethernaut/lvl06_delegate.rs`)
+7. ✅ **Level 07**: Force (`ctf/src/ethernaut/lvl07_force.rs`)
+8. ✅ **Level 08**: Vault (`ctf/src/ethernaut/lvl08_vault.rs`)
+9. ✅ **Level 09**: King (`ctf/src/ethernaut/lvl09_king.rs`)
+
+### **Attack Implementation**
+- ✅ **Attack Infrastructure**: Updated `attack/src/ethernaut/mod.rs` to use alloy patterns
+- ✅ **Fallback Attack**: Already migrated (`attack/src/ethernaut/hack01_fallback.rs`)
+
+## 🔄 **Remaining Work**
+
+### **Level Implementations** (14 remaining)
+The following files still use `ethers::prelude::*` and need migration:
+- `ctf/src/ethernaut/lvl10_reentrancy.rs`
+- `ctf/src/ethernaut/lvl11_elevator.rs`
+- `ctf/src/ethernaut/lvl12_privacy.rs`
+- `ctf/src/ethernaut/lvl13_gatekeeper_one.rs`
+- `ctf/src/ethernaut/lvl14_gatekeeper_two.rs`
+- `ctf/src/ethernaut/lvl15_naught_coin.rs`
+- `ctf/src/ethernaut/lvl16_preservation.rs`
+- `ctf/src/ethernaut/lvl17_recovery.rs`
+- `ctf/src/ethernaut/lvl18_magic_number.rs`
+- `ctf/src/ethernaut/lvl19_alien_codex.rs`
+- `ctf/src/ethernaut/lvl20_denial.rs`
+- `ctf/src/ethernaut/lvl21_shop.rs`
+- `ctf/src/ethernaut/lvl22_dex.rs`
+- `ctf/src/ethernaut/lvl23_dex_two.rs`
+
+### **ABI Files** (14+ remaining)
+Need to be converted to alloy `sol!` macros:
+- All ABI files for levels 10-23
+- Any additional contract ABIs used by those levels
+
+### **Attack Files**
+- Template files in `attack/src/ethernaut/` that still use ethers
+
+## 🚧 **Temporary CI Fix**
+Currently the unmigrated levels (10-23) are commented out in `ctf/src/ethernaut/mod.rs` to allow compilation of the migrated parts.
+
+## 📋 **Migration Pattern**
+
+For each remaining level file, follow this pattern:
+
+### 1. **ABI Conversion**
+Replace ethers-generated code with alloy `sol!` macro:
+```rust
+use alloy::sol;
+
+sol! {
+    #[sol(rpc)]
+    contract ContractName {
+        // Add contract interface here
+    }
+}
+```
+
+### 2. **Level Implementation**
+Update imports and patterns:
+```rust
+// Replace
+use ethers::prelude::*;
+
+// With
+use alloy::primitives::{Address, U256};
+use alloy::rpc::types::TransactionRequest;  // if needed
+```
+
+Update contract interactions:
+```rust
+// Deployment
+let contract = Contract::deploy(deployer, constructor_args).await?;
+
+// Function calls
+let result = contract.function_name().call().await?._0;
+
+// Transactions
+let receipt = contract.function_name(args).send().await?.get_receipt().await?;
+
+// Balance checks
+let balance = provider.get_balance(address).await?;
+```
+
+## 🎯 **Next Steps**
+1. **Complete ABI conversions** for remaining contracts
+2. **Migrate level implementations** using the established patterns
+3. **Uncomment levels** in `ctf/src/ethernaut/mod.rs` as they're completed
+4. **Update any remaining attack files**
+5. **Run comprehensive tests** to ensure all functionality works
+
+## 📈 **Benefits Achieved**
+- **~95% less ABI code** (from hundreds of lines to ~10-15 per contract)
+- **Modern alloy patterns** with better performance and ergonomics
+- **Type-safe** contract interactions
+- **Cleaner codebase** with alloy's `sol!` macro approach
