# Changelog

## 0.1.0 — 2026-05-11

Initial release.

### Added

* `LithoClient` with constructor taking either a `NetworkName` or a custom RPC URL.
* Read methods: `getChainId`, `getBlockNumber`, `getBalance`, `getTransaction`, `getTransactionReceipt`, `waitForTransaction`.
* Retry with exponential backoff on transient failures (network errors, 5xx, 429).
* Typed errors via `LithoError` + `ErrorCode` (re-exported from `@lithosphere/blockchain-core`).
* Re-exports of network registry, ABIs (LEP100, WLITHO, LITHONative), and shared types so a single install is enough for most consumers.
* Dual ESM + CJS build via `tsup`; bundled `.d.ts` for both.

### Dependencies

* Runtime: `@lithosphere/blockchain-core` (workspace).
* Built on `fetch` — no viem / ethers / web3 dependency.
