1.0.0 (2026-04-10)

Initial release of @consensys/linea-sdk-core, the framework-agnostic foundation for Linea bridge SDKs.

Features

• Sparse Merkle Tree -- SparseMerkleTree class with configurable depth and hash function; leaf management, root computation, and Merkle proof generation returning MessageProof
• Block extra data parsing -- parseBlockExtraData to decode Linea block extraData into version and fee parameters
• Message status formatting -- formatMessageStatus mapping on-chain numeric statuses to OnChainMessageStatus enum (UNKNOWN, CLAIMABLE, CLAIMED)
• Contract address resolution -- getContractsAddressesByChainId returning canonical addresses (Linea Rollup, Message Service, Token Bridge) for Ethereum Mainnet, Sepolia, Linea Mainnet, and Linea Sepolia
• Chain identification -- isMainnet, isSepolia, isLineaMainnet, isLineaSepolia predicates

Types

Bridge client surface:

• L1PublicClient / L2PublicClient -- read-only bridge operations (message lookup, status, proof retrieval, block extra data)
• L1WalletClient / L2WalletClient -- write bridge operations (deposit, withdraw, claim)
• Message, ExtendedMessage, MessageProof, OnChainMessageStatus
• Framework-agnostic transaction types (logs, receipts, EIP-compliant request variants)
