Lead decisions

• confirmed· blockfrostprotocol-parameters

  The Blockfrost provider reads /epochs/latest/parameters.

  • packages/provider/src/blockfrost.ts:85const result = await this.fetch(`${this.url}/epochs/latest/parameters`, {

• confirmed· cardano-multiplatform-lib-cmltransaction-encoding

  fromTx decodes any transaction CBOR with the vendored CML, which stops at body key 22.

  • packages/lucid/src/lucid-evolution/LucidEvolution.ts:223CML.Transaction.from_cbor_hex(tx),

• confirmed· koiosprotocol-parameters

  The Koios provider reads /epoch_params.

  • packages/provider/src/koios.ts:78const url = `${this.baseUrl}/epoch_params?limit=1`;

• confirmed· kupoblock-encodingera-identitytransaction-encoding

  The Kupmios provider reads UTxOs and datums from Kupo. Kupo cannot index Dijkstra blocks (R2 gap), so its matches stop at the fork.

  • packages/provider/src/kupmios.ts:236const pattern = `${this.kupoUrl}/matches/${queryPredicate}${isAddress ? "" : "/*"}?unspent&resolve_hashes`;

• confirmed· ogmiosprotocol-parameterstransaction-encodingera-identityplutus-language

  The Kupmios provider reads parameters, submits and evaluates through Ogmios; the Koios provider evaluates through Koios's Ogmios passthrough.

  • packages/provider/src/kupmios.ts:165method: "queryLedgerState/protocolParameters",
  • packages/provider/src/kupmios.ts:483method: "submitTransaction",
  • packages/provider/src/kupmios.ts:526method: "evaluateTransaction",

• confirmed· scalusplutus-script-contexttransaction-encoding

  The scalus-uplc evaluator loads Scalus for ex-unit evaluation, which does not implement PlutusV4.

  • packages/scalus-uplc/src/index.ts:19const loadScalus = (): Promise<Scalus> => (scalusModule ??= import("scalus"));

• not-reached· blockfrostera-identity

  The Blockfrost provider does not call /network/eras.

  • packages/provider/src/blockfrost.ts:85const result = await this.fetch(`${this.url}/epochs/latest/parameters`, {

• not-reached· cardano-multiplatform-lib-cmlblock-encodingera-identityplutus-languageprotocol-parametersstake-pool-registration

  Otherwise CML builds Lucid's own transactions.

  • packages/lucid/src/lucid-evolution/LucidEvolution.ts:223CML.Transaction.from_cbor_hex(tx),

• not-reached· koiosera-identity

  The Koios provider reads no era names.

  • packages/provider/src/koios.ts:78const url = `${this.baseUrl}/epoch_params?limit=1`;

• not-reached· ogmiosblock-encoding

  Chain-sync appears only in the experimental devnet's node trace settings.

  • packages/experimental/src/Devnet/DevnetDefault.ts:44readonly TraceChainSyncClient: boolean;

• not-reached· pallasblock-encodingera-identity

  The uplc evaluator package decodes transactions through Aiken's eval_phase_two_raw, which names the Conway era; no blocks are decoded and no era is detected.
