v0.3.0

Minor Changes

• b381ffe: add EVM verifier address constants and tuple helpers

  Export deployed Molpha verifier addresses for Ethereum Sepolia, Arbitrum Sepolia,
  Avalanche Fuji, and BSC testnet, plus framework-agnostic helpers to convert
  DataUpdateResult into verify(DataUpdate, SchnorrSignature) contract arguments
  for use with ethers or viem.

• 113b5d3: add a cached-context "short" flow to MolphaGateway.execute

  Introduce ExecuteContext (registryVersion, nodes, jobConfig) and a
  gateway.prepareContext(jobId) helper that fetches these slow-changing round
  inputs once. Pass them back via execute({ ..., context }) (also accepted by
  executeAndSubmit) to skip the prelude and run rounds as a single gateway POST.
  context is partial, so any omitted field is still fetched. The default full
  flow now also fetches the registry version, node set, and job config in
  parallel.

Patch Changes

• b381ffe: improve gateway execution reliability and align API config hash defaults

  canonicalizeAPIConfig now defaults valueTransform to an empty string instead of multiply:1e6, so API config hashing reflects explicit transforms only. Gateway execution now retries job-config fetches on transient 404 responses for newly created jobs, and gateway errors include backend-provided details for easier debugging of 400, 503, and other non-OK responses.

• 113b5d3: add Starknet verifier address helpers and calldata builders

  Expose the deployed Starknet Sepolia verifier address and helpers to convert a
  gateway DataUpdateResult into Starknet verifier DataUpdate and
  SchnorrSignature calldata structs.
