@polygonlabs/meta@1.1.1

Patch Changes

• 02b6d2b: Lower the published engines.node floor from >=24 to >=20 to match the package's actual runtime requirements.

  @polygonlabs/meta ships only as const data modules — typed ABIs and network metadata — with zero runtime code; every module under dist/generated/** is a plain export const ... = [...] as const literal. It has no Node 24 runtime dependency. The previous >=24 floor described the build toolchain (codegen runs node scripts/codegen.ts via Node's native TypeScript execution), not what consumers need to run the package, and surfaced a spurious engine-mismatch warning for anyone targeting Node 20.

  The build-time Node 24 requirement is now declared explicitly in devEngines.runtime and documented in CONTRIBUTING, leaving engines.node to describe the consumer runtime. Downstream SDKs that target Node 20 — such as @polygonlabs/pos-sdk — can now depend on @polygonlabs/meta without inheriting an inaccurate Node 24 floor.

@polygonlabs/meta@1.1.0

Minor Changes

• b110fd0: Add MultiRootDistributor ABI and addresses for Sepolia testnet.

  The Polygon Apps Team's priority-fee distribution contract is now indexed under a new
  Main.PriorityFeeDistributionContracts sub-group on testnet/amoy/index.json (the section
  labelled Main carries Sepolia entries):

  • MultiRootDistributorProxy — 0x1Ff397F3BCDA58952Ac2326A1Fb799f9FBE6ecd7 (transparent
    upgradeable proxy, deployed at Sepolia block 10833197).
  • MultiRootDistributor — 0x42666db9f9dBdE270Bc752E776EaD2967E606679 (implementation).

  Consumers can now import the typed ABI via
  @polygonlabs/meta/abi/testnet/amoy/plasma/MultiRootDistributor or reference the raw JSON
  through the ./network/* subpath. The contract emits
  Claimed(bytes32 indexed root, uint256 indexed index, address indexed account, uint256 amount)
  plus four root-lifecycle events (RootAdded, RootRemoved, RootStateChanged,
  RootToppedUp); the downstream pos-staker-pool-claims subgraph in 0xPolygon/subgraphs
  indexes the proxy address using this ABI.

  Ethereum mainnet additions will follow in a subsequent release once the contract deploys to
  mainnet.

@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.
