The foundational SDK for web3 and data

Why Lattice

Most blockchain SDKs force you to choose between security, scalability, and developer experience. Lattice is designed from first principles so you don't have to. State is inherently verifiable. Chains scale horizontally without splitting security. Every layer is standalone — use the full SDK or pick the primitives you need.

The Storage Chain

Every piece of data flows through a tiered worker chain — fast to slow, local to remote. Misses walk forward; hits backfill backward. The chain self-optimizes without orchestration.

SDK Packages

Eight packages spanning blockchain, state, storage, networking, and reputation. Each is independently useful — compose them to match your use case, from a local verifiable data store to a full multi-chain network.

SDK Design Principles

Quick Start

import Acorn
import AcornMemoryWorker
import AcornDiskWorker

let memory = MemoryCASWorker()
let disk = await DiskCASWorker(
    directory: "/tmp/lattice",
    near: memory
)
let composite = CompositeCASWorker(farthest: disk)

// Store content-addressed data
let data = Data("Hello, Lattice".utf8)
let cid = await composite.store(data: data)

// Retrieve — walks memory → disk automatically
let result = await composite.get(cid: cid)
// First get: disk hit, backfills to memory
// Second get: memory hit in ~10ns
