Overview

This skill explains token standards on Hyperliquid: ERC-20 and other EVM-compatible standards on HyperEVM, plus HIP-1/HIP-2/HIP-3 native standards on HyperCore. It clarifies when to use each standard, how native HyperCore tokens differ from EVM tokens, and the key interfaces and flows for creating markets and liquidity. The goal is a practical decision guide for launches, trading, and cross-layer composability.

How this skill works

The skill inspects the two-layer model: HyperEVM uses standard EVM token interfaces (ERC-20, ERC-721, ERC-4626, ERC-2612) that behave like Ethereum. HyperCore implements protocol-level native tokens (HIP-1) with built-in spot orderbooks and automated liquidity (HIP-2) and allows builder-controlled DEXs (HIP-3). It shows creation flows: API-based HIP-1 deployment and HIP-2 seeding, versus smart-contract ERC-20 deployment on HyperEVM.

When to use it

• Use ERC-20 on HyperEVM when you need full EVM composability and DeFi integrations (DEXs, lending, vaults).
• Choose ERC-4626 for tokenized vaults and yield-bearing contract patterns.
• Use HIP-1 on HyperCore when you want native spot trading and immediate orderbook presence.
• Seed HIP-2 if you want built-in AMM-style liquidity and to avoid cold-start liquidity problems.
• Use HIP-3 to run a curated or platform-specific spot DEX with listing control and optional fees.

Best practices

• Launch as HIP-1 to obtain instant native trading, then bridge to HyperEVM for DeFi composability.
• Seed sufficient HIP-2 liquidity on launch to ensure price discovery and reduce volatility.
• Keep HIP-1 token parameters conservative: name ≤20 chars, symbol ≤6 chars, choose decimals (commonly 6 or 8).
• Use ERC-20 for governance or contracts requiring on-chain mint/burn logic; HIP-1 supply is fixed at creation.
• Confirm token decimal conventions (USDC=6 on HyperEVM) to avoid integration errors.

Example use cases

• Launch a speculative token: create HIP-1 and seed HIP-2 for instant market depth. Then wrap to ERC-20 for yield integrations.
• Deploy a governance token on HyperEVM (ERC-20) to integrate with HyperSwap V2 and lending protocols.
• Create a curated marketplace using HIP-3 to control listing and charge platform fees.
• Build a staking vault as an ERC-4626 on HyperEVM while using a HIP-1 wrapper for spot trading on HyperCore.
• Issue NFTs or collectible assets using ERC-721 on HyperEVM where EVM tooling is required.
