@piplabs/cdr-sdk v0.1.1

What's new

Cosmos ABCI DKG queries (#45)
Query DKG state 6–20x faster via CometBFT abci_query instead of scanning EVM event logs.

const client = new CDRClient({
  network: "testnet", publicClient, walletClient,
  dkgSource: "cosmos-abci",
  cometRpcUrl: "http://your-node:26657",
});

SGX attestation verification (#31)
Verify validator TEE enclaves before trusting their partial decryptions.

import { verifyAttestation } from "@piplabs/cdr-sdk";
const result = verifyAttestation(report, { mrEnclave, mrSigner, minSvn: 1 });

Condition helpers (#28)
Encode condition data without manual ABI encoding.

import { conditions } from "@piplabs/cdr-sdk";

// Works with deployed OwnerWriteCondition on Aeneid
conditions.ownerOnly({
  address: "0x4C9bFC96d7092b590D497A191826C3dA2277c34B",
  owner: "0x...",
});

// Works with any condition contract (e.g. LicenseReadCondition)
conditions.custom({
  address: "0xC0640AD4CF2CaA9914C8e5C44234359a9102f7a3",
  conditionData: "0x...",
});

Also available: conditions.open() , conditions.tokenGate() , conditions.merkle() — these require deploying your own condition contracts.

DX improvements (#28)

  • accessCDR() auto-generates ephemeral keys and queries threshold when omitted
  • createVault / readVault / createFileVault / readFileVault method aliases
  • Validation RPC: validationRpcUrls for cross-node globalPubKey verification

Bug fixes

  • Observer now uses getActiveRound() to find the correct active DKG round (#38)
  • HeliaProvider passes CID as string to avoid multiformats version mismatch (#41)
  • Synapse storage connection handling (#44)

Breaking changes

  • dkgSource: "cosmos-api" renamed to "cosmos-abci", dkgApiBase → cometRpcUrl (#45)
