Patch Changes

• #101 aaf0882 Thanks @solidsnakedev! - ### Core Module Enhancements

  Mint Module

  • Added Mint.getByHex() and Mint.getAssetsByPolicyHex() utilities for hex-based lookups
  • Fixed Mint.insert, removePolicy, removeAsset, and get to use content-based equality (Equal.equals) instead of reference equality for PolicyId/AssetName lookups

  Fee Calculation

  • Fixed calculateFeeIteratively to include mint field in fee calculation via TxContext access
  • Removed unnecessary 5000n fee buffer that caused fee overpayment

  Transaction Builder

  • Added .mint() method to TransactionBuilder for native token minting/burning
  • .attachScript() now accepts { script: CoreScript } parameter format
  • Improved type safety by using Core types directly instead of SDK wrappers

  Devnet Package

  Test Infrastructure

  • Added TxBuilder.Mint.test.ts with devnet submit tests for minting and burning
  • Updated TxBuilder.Scripts.test.ts to use Core types (PlutusV2.PlutusV2) instead of SDK format
  • Refactored createCoreTestUtxo helper to accept Core Script types directly
  • Removed unused createTestUtxo (SDK format) helper
  • Added Genesis.calculateUtxosFromConfig() for retrieving initial UTxOs from genesis config
  • Replaced all Buffer.from().toString("hex") with Text.toHex() in tests

  Breaking Changes

  • attachScript() now requires { script: ... } object format instead of passing script directly
  • Test helpers now use Core types exclusively

• #103 65b7259 Thanks @solidsnakedev! - ### Remove Buffer Usage from Source Code

  Replaced all Buffer.from() usage with Bytes.fromHex() and Bytes.toHex() from the core module for better cross-platform compatibility.

  Files Updated:

  • TxBuilderImpl.ts - Use Bytes.toHex() for key hash hex conversion in buildFakeWitnessSet
  • Assets/index.ts - Use Bytes.fromHex() for policy ID and asset name decoding
  • MaestroEffect.ts - Use Bytes.fromHex() for transaction CBOR conversion
  • Ogmios.ts - Use Bytes.toHex() for datum hash hex conversion
  • KupmiosEffects.ts - Use Bytes.fromHex() for datum hash and script bytes decoding

• #104 c26391a Thanks @solidsnakedev! - ### PlutusV3 Minting Support

  • Add PlutusV3 script minting with automatic script evaluation via Ogmios
  • Add mintAssets builder method for Plutus script-based minting policies
  • Add attachScript builder method for attaching Plutus scripts to transactions
  • Support both minting (positive amounts) and burning (negative amounts)

  Redeemer API Improvements

  • Breaking: Change redeemer parameter type from string (CBOR hex) to Data.Data
    • Affects collectFrom() and mintAssets() builder methods
    • Provides type-safe redeemer construction without manual CBOR encoding
    • Example: redeemer: Data.constr(0n, [Data.int(1n)]) instead of hex strings

  Core Module Additions

  • Add Redeemers module with Conway CDDL-compliant encoding (array format)
  • Refactor hashScriptData to use proper module encoders for redeemers and datums
  • Add Redeemers.toCBORBytes() for script data hash computation

  Internal Improvements

  • Store PlutusData.Data directly in builder state instead of CBOR hex strings
  • Remove redundant CBOR hex encoding/decoding in transaction assembly
  • Add PlutusV3 minting devnet tests with real script evaluation
