XL1 Blockchain Knowledge

This skill covers the XL1 blockchain (XYO Layer One) — a data-focused Layer 1 designed for high-throughput data applications. XL1 extends the XYO protocol with blockchain primitives: blocks, transactions, fees, staking, and consensus.

Lower Layer Skills

XL1 builds on the full skill stack. When working on XL1 projects, also consult:

• XYO Knowledge — for protocol primitives (payloads, bound witnesses, modules, accounts, wallets)
• XY Toolchain — for build tooling (@xylabs/toolchain, ESLint, TypeScript config, Vitest)
• Development — for coding conventions (TypeScript, Git, testing, workflow)

When you need to look up exact type definitions, install the relevant @xyo-network/xl1-* package and read the TypeScript declarations at dist/neutral/index.d.ts. The XL1 Protocol Yellow Paper provides the full protocol specification.

Critical: Never Issue Raw RPC Calls

The XL1 gateway is reached exclusively through the SDK. Two rules apply to every piece of code that touches chain access — dApp, service, indexer, test, verification script:
