Lead decisions

• confirmed· cardano-serialization-lib-cslplutus-language

  The offline evaluator decodes arbitrary transactions and the builder constructs Plutus scripts from a language value through CSL.

  • packages/evaluator/src/context/resolver.ts:125tx = CardanoWASM.Transaction.from_hex(txHex)
  • packages/hydra-transaction/src/tx-builder/index.ts:245const plutusScript = CardanoWASM.PlutusScript.from_hex_with_version(scriptCbor, language)

• confirmed· cardano-serialization-lib-cslprotocol-parametersstake-pool-registrationtransaction-encoding

  The offline evaluator decodes arbitrary transactions with CSL, whose body decoder rejects keys beyond 22, parameter updates beyond key 33 and pool certificates with a BLS key.

  • packages/evaluator/src/context/resolver.ts:125tx = CardanoWASM.Transaction.from_hex(txHex)
  • packages/hydra-transaction/src/tx-builder/index.ts:245const plutusScript = CardanoWASM.PlutusScript.from_hex_with_version(scriptCbor, language)

• confirmed· ogmiostransaction-encodingera-identity

  The Ogmios provider submits transactions through Ogmios.

  • packages/core/src/utils/providers/ogmios.provider.ts:140const response = await this.rpcRequest<{ result: { transaction: { id: string } } }>('submitTransaction', {

• confirmed· whiskytransaction-encodingplutus-language

  The evaluator package hands arbitrary transaction hex to whisky-evaluator's js_evaluate_tx_scripts, which decodes Conway bodies only and does not evaluate PlutusV4.

  • packages/evaluator/src/engine/whisky.ts:36const WHISKY_PACKAGE = 'whisky-evaluator'
  • packages/evaluator/src/engine/whisky.ts:97if (!mod || typeof mod.js_evaluate_tx_scripts !== 'function') {

• not-reached· blockfrostera-identityprotocol-parameters

  The Blockfrost provider reads UTxOs and submits; it reads no parameters or eras.

  • packages/core/src/utils/providers/blockfrost.provider.ts:132const submitTx = async (txHex: string): Promise<string> => {

• not-reached· cardano-serialization-lib-cslblock-encoding

  CSL decodes transactions here, not blocks.

  • packages/evaluator/src/context/resolver.ts:125tx = CardanoWASM.Transaction.from_hex(txHex)
  • packages/hydra-transaction/src/tx-builder/index.ts:245const plutusScript = CardanoWASM.PlutusScript.from_hex_with_version(scriptCbor, language)

• not-reached· ogmiosblock-encodingplutus-languageprotocol-parameters

  The Ogmios provider otherwise only queries UTxOs; evaluation, parameter and era calls are in the playground app.

  • packages/core/src/utils/providers/ogmios.provider.ts:122const response = await this.rpcRequest<{ result: AddressUtxoResponse }>('queryLedgerState/utxo', {

• not-reached· whiskyera-identityprotocol-parameters

  The evaluator names the era itself and takes cost models from its caller; era detection and parameter decoding are not used.
