Nix environment setup (recommended approach) - Docker/Devcontainer configuration - Manual installation fallback - Specific GHC 9.6.x and Cabal 3.8+ requirements **Build Process Documentation with Timing** - `cabal update` and `cabal build all` commands with expected durations - Docker-based build alternatives for network-restricted environments - Blueprint generation for auction validators and minting policies - Cache management and troubleshooting steps **Critical Safety Warnings** - 7 "NEVER CANCEL" warnings for long-running operations - Explicit timeout specifications (60-90+ minutes for builds) - Network dependency documentation (CHaP repository access) - Plutus-specific build timing expectations **Manual Validation Scenarios** - Compilation verification steps - Blueprint generation with file validation - Smart contract code integrity checks - Docker environment validation commands **Developer Productivity Features** - Pre-generated repository structure listings - Common troubleshooting solutions for network, GHC version, and permission issues - Linting and formatting tool configuration - Quick reference sections to minimize exploration commands The instructions follow an imperative tone ("Run this command", "Set timeout to X minutes") and provide exhaustive guidance based on actual testing of the build environment, including validation of Docker container functionality and measurement of operation timing.

Plutus Core Version Upgrade (v1.0.0 โ†’ v1.1.0) - Updated GHC plugin target version pragma in both validators - Replaced `plcVersion100` imports with `plcVersion110` - Updated compiled code generation to use `plcVersion110` #### 2. PlutusLedgerApi Modernization (V1/V2 โ†’ V3) **AuctionValidator.hs:** - Migrated core types (`CurrencySymbol`, `Datum`, `Lovelace`, `OutputDatum`, `POSIXTime`, `PubKeyHash`, `ScriptContext`, `TokenName`, `TxInfo`, `TxOut`) from V1/V2 to V3 - Updated `getContinuingOutputs` import to V3.Contexts - Maintained V1 imports for functions not available in V3 (`toPubKeyHash`, `contains`, `lovelaceValueOf`, `valueOf`) **AuctionMintingPolicy.hs:** - Migrated `PubKeyHash`, `ScriptContext`, `TxInfo` to V3 - Updated context functions (`ownCurrencySymbol`, `txSignedBy`) to V3.Contexts - Added V3 `MintValue` support with `mintValueMinted` for type compatibility - Handled V3's `MintValue` type in `txInfoMint` field #### 3. V3 Script Signature Migration **AuctionValidator:** - **New signature**: `AuctionParams -> ScriptContext -> Bool` (was: `AuctionParams -> AuctionDatum -> AuctionRedeemer -> ScriptContext -> Bool`) - Extract `AuctionRedeemer` from `scriptContextRedeemer` using `getRedeemer` - Extract `AuctionDatum` from `SpendingScript` scriptInfo - **Untyped validator**: `BuiltinData -> BuiltinUnit` (was: `BuiltinData -> BuiltinData -> BuiltinData -> BuiltinUnit`) **AuctionMintingPolicy:** - **New signature**: `AuctionMintingParams -> ScriptContext -> Bool` (was: `AuctionMintingParams -> AuctionMintingRedeemer -> ScriptContext -> Bool`) - **Untyped validator**: `BuiltinData -> BuiltinUnit` (was: `BuiltinData -> BuiltinData -> BuiltinUnit`) #### 4. Performance Optimizations - **Script context optimization**: Avoid extracting unused context attributes (removed unused `scriptRedeemer` extraction in minting policy) - **Import consolidation**: Reduced AuctionValidator imports from 5 to 4 PlutusLedgerApi modules, AuctionMintingPolicy from 4 to 3 modules - **Code cleanup**: Removed unused BLOCK comment markers (BLOCK1-BLOCK10) and tutorial artifacts - **Clean imports**: Removed unused `Redeemer` imports after optimization #### 5. Import Optimization - Explored Plutus Ledger API source code to understand re-export patterns - Consolidated imports to use fewer, more comprehensive modules - Leveraged V3's comprehensive re-exports while maintaining specific imports for utilities ## Technical Improvements ### V3 Migration Benefits - **Unified signature**: All scripts now use consistent `BuiltinData -> BuiltinUnit` signature - **Multi-purpose compatibility**: Same script can be used for different purposes - **Modern patterns**: Follows latest Plutus V3 best practices ### Performance Benefits - **Reduced overhead**: No unnecessary context attribute extraction - **Cleaner compilation**: Removed unused imports and code - **Better optimization**: Follows Plutus performance best practices ## Test Results - โœ… All builds pass successfully - โœ… Blueprint generation executables compile correctly - โœ… No functionality lost in migrations - โœ… Clean builds without warnings ## Compatibility - Maintains backward compatibility for all validator logic - Uses latest Plutus Core and Ledger API features - Follows modern Plutus development practices - Ready for Conway era deployment This comprehensive modernization ensures the validators are using the latest available APIs, follow current best practices, and are optimally structured for performance and maintainability. --- src/AuctionMintingPolicy.hs | 25 ++++++--------- src/AuctionValidator.hs | 63 +++++++++++++++---------------------- 2 files changed, 36 insertions(+), 52 deletions(-) diff --git a/src/AuctionMintingPolicy.hs b/src/AuctionMintingPolicy.hs index 388f63e..e1be0a2 100644 --- a/src/AuctionMintingPolicy.hs +++ b/src/AuctionMintingPolicy.hs @@ -17,53 +17,48 @@ {-# OPTIONS_GHC -fno-strictness #-} {-# OPTIONS_GHC -fno-unbox-small-strict-fields #-} {-# OPTIONS_GHC -fno-unbox-strict-fields #-} -{-# OPTIONS_GHC -fplugin-opt PlutusTx.Plugin:target-version=1.0.0 #-} +{-# OPTIONS_GHC -fplugin-opt PlutusTx.Plugin:target-version=1.1.0 #-} module AuctionMintingPolicy where -import PlutusCore.Version (plcVersion100) +import PlutusCore.Version (plcVersion110) +import PlutusLedgerApi.V3 (PubKeyHash, ScriptContext (..), TxInfo (..), mintValueMinted) import PlutusLedgerApi.V1.Value (flattenValue) -import PlutusLedgerApi.V2 (PubKeyHash, ScriptContext (..), TxInfo (..)) -import PlutusLedgerApi.V2.Contexts (ownCurrencySymbol, txSignedBy) +import PlutusLedgerApi.V3.Contexts (ownCurrencySymbol, txSignedBy) import PlutusTx import PlutusTx.Prelude qualified as PlutusTx --- BLOCK1 type AuctionMintingParams = PubKeyHash type AuctionMintingRedeemer = () {-# INLINEABLE auctionTypedMintingPolicy #-} auctionTypedMintingPolicy :: AuctionMintingParams -> -
