Chainlink Local v0.2.6 API Reference

Chainlink Local v0.2.6 adds CCIPLocalSimulatorFork.switchChainAndRouteMessage(uint256[] memory chainIds) for routing multiple CCIP messages to multiple chains in a single call, and refactors the fork simulator so it routes every message sent from a loop, not just the first one.

CCIP

These contracts provide Cross-Chain Interoperability Protocol (CCIP) functionality in a local testing environment:

• CCIPLocalSimulator - Local CCIP simulator (no-fork mode)
• CCIPLocalSimulatorFork - CCIP simulator for forked networks
• CCIPLocalSimulatorFork JS - JavaScript helpers for fork routing
• Register - CCIP network configuration registry

Data Streams

Contracts for simulating Chainlink Data Streams:

• DataStreamsLocalSimulator - Local Data Streams simulator (no-fork mode)
• DataStreamsLocalSimulatorFork - Data Streams simulator for forked networks
• MockVerifier - Mock Data Streams verifier
• MockVerifierProxy - Mock Data Streams verifier proxy
• MockReportGenerator - Signed report generator for every report schema
• MockFeeManager - Mock verifier fee manager
• MockRewardManager - Mock reward manager
• ReportVersions - Data Streams report schemas
• Register (Data Streams) - Data Streams network configuration registry

Data Feeds

Contracts for simulating Chainlink Data Feeds:

• AggregatorInterface - Basic price feed interface
• AggregatorV2V3Interface - Combined V2/V3 price feed interface
• AggregatorV3Interface - Extended price feed interface
• MockOffchainAggregator - Mock implementation of off-chain aggregator
• MockV3Aggregator - Mock implementation of V3 aggregator

Token Contracts

Standard token implementations for testing:

• BurnMintERC677Helper - Helper contract for ERC677 token operations
