Synchronize documentation with recent API and type refactors across the codebase. Key updates include: - Rename and usage updates for factory ABI exports (e.g. OP20FactoryAbi, MotoChefFactoryAbi) and template ABIs. - Replace RevertDecoder class with decodeRevertData and update examples accordingly. - Change CallResult/contract API types (Uint8Array for calldata/notes, new return shapes, send/sign signatures) and update examples to use try/catch (contracts now throw on revert). - Provider API signature and options changes (timeout, fetcherConfigurations/Agent.Options, useThreadedHttp) and some provider method return-type adjustments. - Epoch API: rename targetHash -> checksumRoot and adjust related types/usage. - UTXO manager/UTXO API: introduce UTXO/UTXOsManager class-like interfaces, additional request options (mergePendingUTXOs, filterSpentUTXOs, olderThan, CSV flags), getPending/getMultiple, and adjust examples. - Block witnesses: getBlockWitness now returns an array of block witness results; update interfaces and all example usages to handle paged/multi-block responses. - Reorg detection: ReorgInformation fields renamed to fromBlock/toBlock and examples updated. - ContractData/ContractData class: expand/rename fields and update examples to treat address as string. - Gas estimation and other type tweaks: introduce class-like interfaces and readonly fields for some structures. - Transaction parameter changes: note now supports Uint8Array and p2wda flag added; various encoding/enum flag changes (input/output flags re-ordered and documented). - Examples expanded for factory/MotoChef usage, deployments, and event types; many code samples adjusted to new method signatures and return shapes. Also updated related TypeScript test file and small doc corrections to align with the above API changes. These changes keep docs consistent with recent runtime/type refactors and new method signatures.

Wrap several thrown Errors with the original error as the 'cause' to preserve error context (Contract.ts, JSONThreader.ts, SequentialWorker.ts, WorkerCreator.native.ts). Also apply minor formatting and import cleanups (reflow multi-line imports, remove redundant parentheses around await, tighten setTimeout calls) and disable the 'no-useless-assignment' ESLint rule in eslint.config.js.
Bump package version to 1.8.1-rc.2 and refactor provider APIs and websocket typing. Key changes: - package.json: version updated to 1.8.1-rc.2. - src/providers/JSONRpcProvider.ts: introduce JSONRpcProviderConfig interface and switch constructor to accept a config object; expose new config fields (timeout, fetcherConfigurations, useThreadedParsing, useThreadedHttp) with sensible defaults; internal fetcher fields extracted; setFetchMode is commented out; include original error as cause on timeout. - src/providers/WebsocketRpcProvider.ts: introduce WebSocketRpcProviderConfig and validate URL (must start with ws:// or wss://); compose config from DEFAULT_CONFIG and provided websocketConfig; reorganize imports to use new typed modules. - src/providers/websocket/MethodMapping.ts: add a dedicated METHOD_MAPPINGS file (JSON-RPC to WebSocket opcode/type mappings) and import it from the WebSocket provider. - Remove barrel exports: src/providers/websocket/index.ts and src/providers/websocket/types/index.ts were deleted in favor of explicit typed exports. These changes improve configuration clarity, modularize websocket type mappings, and enforce stricter WebSocket URL validation.
Update docs and examples to initialize JSONRpcProvider/WebSocketRpcProvider with a single config object ({ url, network, ... }) instead of positional args. Add JSONRpcProviderConfig and WebSocketRpcProviderConfig shapes in docs, remove/replace outdated REST-mode constructor references, and update various examples to use fetcherConfigurations/timeout/useThreadedParsing/useThreadedHttp fields. Adjust related inline examples in src comments and update test expectation for threaded HTTP config usage. Also bump package version to 1.8.1-rc.2.
Update dependencies: bump @btc-vision/bip32 to ^7.1.2, @btc-vision/ecpair to ^4.0.5 and change @btc-vision/bitcoin from a local file reference to ^7.0.0-rc.4. In src/threading/SharedThreader.ts add explicit type annotations for several private fields, reorder and mark stats-related fields, simplify unload/window/self event listener conditionals, and apply minor formatting changes. These edits improve type safety and code clarity without changing runtime behavior.
Interpret a revert field as a valid revert even if it's an empty string and expose a failed flag on receipts. Update DeploymentTransaction to only allow missing deployerAddress when revert is present (not null/undefined). Add documentation comments to transaction interfaces clarifying revert semantics and set TransactionReceipt.failed based on presence of revert. Also update tests to use Satoshi bigint and RawEventList. The rest of the changes are non-functional cleanups: import/order and formatting tweaks, condensed ternaries in CallResultSerializer and ContractData, minor refactors in InteractionTransaction, WorkerCreator boolean expression simplification, and small test import reorders.
Store the raw UTXO as nonWitnessUtxoBase64 (base64 string) and introduce a lazily-decoded getter nonWitnessUtxo that returns a Uint8Array. The decoded value is cached in a private _nonWitnessUtxo to avoid repeated decoding. The getter throws if no raw data is available and includes JSDoc explaining its purpose (required for signing non-segwit inputs). Constructor updated to assign the raw base64 string instead of a decoded buffer.
Introduce a lazily-evaluated, cached getter for nonWitnessUtxo that decodes the base64 raw transaction to a Uint8Array on first access (using fromBase64). Replace the previous eager getter/_nonWitnessUtxo pattern with a defined property installed in the constructor when raw data exists. Update typings and JSDoc to reflect the new optional nonWitnessUtxo field and add explanatory comments. Also fix misspelled @category tags in file JSDoc.

Pull request overview
This PR synchronizes the library and documentation with recent breaking runtime/type refactors: migrating binary data handling from Buffer to Uint8Array, updating provider constructors to accept config objects, and aligning docs/tests/examples with new call/receipt/revert semantics. It also bumps dependencies and upgrades ESLint to v10.
Changes:
- Refactor public-facing types and internal decoding/serialization to use
Uint8Array(calldata, receipts, scripts, epoch/challenge fields, etc.). - Update provider constructors/APIs (JSON RPC + WebSocket) to accept config objects and adjust threading/timeouts behavior; reorganize WebSocket mappings/types exports.
- Update tests + docs/examples to reflect new signatures, revert handling (throwing), and updated API return shapes.

There was a problem hiding this comment.
deployerHashedPublicKey is derived from raw.deployerAddress, but IRawContract.deployerAddress is typed as Address. raw.deployerAddress instanceof Address will always be true for well-typed inputs, and casting it to string then fromHex(...) will produce invalid hex (e.g., "[object Object]") and throw. If the API actually returns a hex string, the fallback branch decodes it as base64 which is also incorrect.
Recommendation: make IRawContract.deployerAddress accurately reflect the API (likely string/hex), decode it consistently with fromHex after stripping an optional 0x prefix, and/or add an explicit deployerHashedPublicKey field instead of overloading deployerAddress.

The new "revert can be an empty string" semantics aren't consistently applied here. this.rawRevert = receipt.revert ? ... : undefined treats an empty string as falsy, so rawRevert/revert stay undefined even though failed is set to true.
Recommendation: use the same presence check as failed (null/undefined) when deciding whether to decode, and handle receipt.revert being a Uint8Array now that the interface allows it (don’t unconditionally cast to string).

JSONRpcProviderConfig exposes fetcherConfigurations?: Agent.Options, but this file currently relies on undici/types/* to reference that type. To keep the public type surface stable across TS/bundlers, prefer referencing Agent from the main undici entrypoint (e.g., import type { Agent } from 'undici') rather than internal undici/types/... paths.

src/opnet.ts no longer re-exports the WebSocket surface from ./providers/websocket/index.js, but it also doesn’t re-export OPNetError. The docs in this PR still show import { JSONRpcProvider, OPNetError } from 'opnet', so consumers will break.
Recommendation: explicitly export OPNetError (and any other intended public websocket exports) from the entrypoint to match the documented public API.

WebSocketRpcProvider is now configured via an object and the JSON-RPC side has been updated to use checksumRoot for epoch submission, but the WebSocket submit-epoch path in this class still references targetHash (see the SUBMIT_EPOCH request mapping further down). That will result in undefined being sent when users pass checksumRoot.
Recommendation: update the submit-epoch mapping to read checksumRoot (and update any protobuf field mapping/comments accordingly) so WebSocket and HTTP providers accept the same parameter names.

Description
Synchronize documentation with recent API and type refactors across the codebase. Key updates include:
Also updated related TypeScript test file and small doc corrections to align with the above API changes. These changes keep docs consistent with recent runtime/type refactors and new method signatures.
Introduce a lazily-evaluated, cached getter for nonWitnessUtxo that decodes the base64 raw transaction to a Uint8Array on first access (using fromBase64). Replace the previous eager getter/_nonWitnessUtxo pattern with a defined property installed in the constructor when raw data exists. Update typings and JSDoc to reflect the new optional nonWitnessUtxo field and add explanatory comments. Also fix misspelled @category tags in file JSDoc.
Interpret a revert field as a valid revert even if it's an empty string and expose a failed flag on receipts. Update DeploymentTransaction to only allow missing deployerAddress when revert is present (not null/undefined). Add documentation comments to transaction interfaces clarifying revert semantics and set TransactionReceipt.failed based on presence of revert. Also update tests to use Satoshi bigint and RawEventList. The rest of the changes are non-functional cleanups: import/order and formatting tweaks, condensed ternaries in CallResultSerializer and ContractData, minor refactors in InteractionTransaction, WorkerCreator boolean expression simplification, and small test import reorders.
Update dependencies: bump @btc-vision/bip32 to ^7.1.2, @btc-vision/ecpair to ^4.0.5 and change @btc-vision/bitcoin from a local file reference to ^7.0.0-rc.4. In src/threading/SharedThreader.ts add explicit type annotations for several private fields, reorder and mark stats-related fields, simplify unload/window/self event listener conditionals, and apply minor formatting changes.

Update docs and examples to initialize JSONRpcProvider/WebSocketRpcProvider with a single config object ({ url, network, ... }) instead of positional args. Add JSONRpcProviderConfig and WebSocketRpcProviderConfig shapes in docs, remove/replace outdated REST-mode constructor references, and update various examples to use fetcherConfigurations/timeout/useThreadedParsing/useThreadedHttp fields. Adjust related inline examples in src comments and update test expectation for threaded HTTP config usage. Also bump package version to 1.8.1-rc.2.
Wrap several thrown Errors with the original error as the 'cause' to preserve error context (Contract.ts, JSONThreader.ts, SequentialWorker.ts, WorkerCreator.native.ts). Also apply minor formatting and import cleanups (reflow multi-line imports, remove redundant parentheses around await, tighten setTimeout calls) and disable the 'no-useless-assignment' ESLint rule in eslint.config.js.
