@polygonlabs/meta@1.0.0

Major Changes

• 0c1d7e5: Initial release of @polygonlabs/meta, replacing the legacy @maticnetwork/meta@2.x package.

  What's new

  • Per-contract typed deep imports. import { abi } from '@polygonlabs/meta/abi/<chain>/<network>/<type>/<Contract>' pulls exactly one ABI; the rest of the package is tree-shaken at bundle time.
  • as const literal ABI types. Each ABI is exported as a literal tuple so viem, wagmi, and abitype can extract function names, argument types, and return types at the call site. Without as const the type widens to { name: string }[] and consumer-side type inference disappears entirely — the typed-ABI value proposition exists only because of as const.
  • Typed network metadata under /info/<chain>/<network> and /info/networks, also as const.
  • Raw JSON access preserved. The ./network/* subpath export keeps the same path scheme as @maticnetwork/meta@2.x, so consumers who only want JSON migrate by changing the package name.
  • Provenance-stamped publishes via npm OIDC trusted publishing, driven by changesets-on-merge.

  Breaking changes vs @maticnetwork/meta@2.x

  • Package renamed: @maticnetwork/meta → @polygonlabs/meta.
  • ESM-only. require() is no longer supported. Consumers must be ESM and on Node ≥ 24.
  • The Network class is gone. Replace new Network(chain, version).abi(name) with the typed deep imports under ./abi/<chain>/<network>/<type>/<Contract> — same data, fully typed, sync, tree-shakable.
  • Mumbai testnet is gone (already removed upstream); use Amoy.

  The HTTP endpoint at static.polygon.technology is unchanged. See MIGRATION.md for full before/after import examples.
