HyperEVM Onboarding: Wallet, Gas, and Core-to-EVM Transfers
HyperEVM is not a separate chain you bridge to and from. It is the EVM half of Hyperliquid's single blockchain, sharing one consensus and one state with HyperCore, the order-book engine that runs perps and spot. That changes what onboarding means: there is no week-long bridge wait and no foreign network to trust. The few things that actually trip people up are paying gas in HYPE, moving assets across the Core-to-EVM boundary, and one address that will quietly destroy your tokens if you use it wrong.
This guide covers the practical onboarding (add the network, get gas, move funds) and the architecture you need to understand to do it safely. It is based on Hyperliquid's official documentation; settings and parameters change, so confirm the current values on the official docs before you act.
Key points. HyperEVM is Hyperliquid's EVM environment, one state with HyperCore under the same HyperBFT consensus. Add it as a custom network with chain ID 999, RPC https://rpc.hyperliquid.xyz/evm, and currency HYPE. HYPE is the gas token, and gas follows EIP-1559 (base fee plus priority fee). Move assets between HyperCore and HyperEVM with the in-app Transfer button, or to a token's system address. Sending any token other than HYPE to the HYPE address 0x2222...2222 will permanently lose it. The chain uses a dual-block system: fast small blocks (1s, 2M gas) and slow big blocks (1 min, 30M gas) for large transactions.
Add the HyperEVM to your wallet
HyperEVM is EVM-equivalent, so any standard Web3 wallet works. The fastest path is to add it through Chainlist (chainlist.org/chain/999); otherwise, add a custom network manually with the values below.
Setting | Value |
|---|---|
Network name | Hyperliquid |
Chain ID | 999 |
RPC URL | https://rpc.hyperliquid.xyz/evm |
Currency symbol | HYPE |
Block explorer | hyperevmscan.io, purrsec.com, or hyperscan.com |
Verify these from the official docs, not a search result or a DM. Fake RPCs and lookalike networks are a common way to drain wallets. Confirm the chain ID and RPC on Hyperliquid's own documentation, bookmark it, and never add a network someone sends you unsolicited.
How HyperEVM fits into Hyperliquid
Hyperliquid is one chain with two parts. HyperCore holds the perps, spot, and order books, and you interact with it through signed actions rather than ordinary EVM transactions. HyperEVM is a standard EVM for Solidity smart contracts. Because both are secured by the same HyperBFT consensus and share one state, an application on the HyperEVM can read and build on the native order-book liquidity directly, which is what people mean when they call it CEX-like DeFi.
HyperCore | HyperEVM | |
|---|---|---|
What runs there | Perps, spot, order books | Solidity smart contracts, DeFi, tokens |
How you interact | Signed actions (native API / app) | Normal EVM transactions |
Gas | No gas on native trades | HYPE, EIP-1559 |
Your identity | Same address | Same address |
The HyperEVM is based on the Cancun EVM (without blobs), so standard toolchains like Foundry and Hardhat work with little modification. Your wallet address is the same on both sides; an externally owned account becomes a recognized Core user simply by receiving a Core asset such as USDC.
Get gas: HYPE on the HyperEVM
HYPE is the gas token on the HyperEVM. The native way to get it is to buy HYPE with USDC on Hyperliquid and then transfer it from HyperCore to the HyperEVM (covered next). You can also bring HYPE or other assets in through third-party bridges such as LayerZero-based routes, deBridge, Stargate, or Gas.zip.
Gas follows the same EIP-1559 model as Ethereum and most L2s: a base fee plus a priority fee. The HyperEVM launched with intentionally low throughput, because it shares state with HyperCore and over-allocating bandwidth early would be risky; that capacity is being raised gradually over successive upgrades. The practical consequence is that gas can spike when demand exceeds the current block space.
Keep a HYPE buffer. Reading state is free, but every state-changing transaction needs HYPE for gas. If your balance runs dry, transactions fail, which matters most during congested, volatile windows when you least want a stuck transaction. Hold a little more HYPE than you think you need.
Move assets between HyperCore and HyperEVM
This is the boundary that confuses newcomers. Funds on HyperCore (your spot balances) and funds on the HyperEVM are tracked separately, even though they live on the same chain. The simplest way to move them is in the app: use the Transfer to/from EVM button on the Balances table, or the EVM to Core Transfer control at the top of the Portfolio page.
Gas is charged on the side you are leaving: sending from the HyperEVM to your spot balance costs HYPE gas on the HyperEVM, while sending from spot to the HyperEVM costs HYPE gas on HyperCore. Keep a little HYPE on both sides so a transfer never strands you.
The system-address method, and the trap
Under the hood, each token has a system address on HyperCore. You can move a token by sending it to that address: an ERC-20 transfer to the system address on the EVM credits it to Core, and a spot send to the system address moves it the other way. HYPE has a special, memorable system address: 0x2222222222222222222222222222222222222222.
Only HYPE may go to 0x2222...2222. That address is for HYPE alone. Send any other token to it and it is permanently lost, with no recovery. Every other asset has its own unique transfer address, and a token has to be linked between Core and the EVM before it can cross at all. Whenever you try a route for the first time, send a tiny test amount before moving size.
The dual-block system you need to understand
The HyperEVM splits its throughput across two kinds of blocks. Fast small blocks give quick confirmation for everyday transactions; slow big blocks carry large transactions such as complex contract deployments. The design deliberately decouples speed from size so both can improve over time instead of being traded off against each other.
Block type | Duration | Gas limit | Use |
|---|---|---|---|
Small (fast) | ~1 second | 2M gas | Everyday transfers and swaps |
Big (slow) | ~1 minute | 30M gas | Large transactions, contract deployment |
These are the initial, conservative parameters and are expected to rise. Builders who need to deploy a large contract opt into big blocks by submitting the evmUserModify action with usingBigBlocks set to true (a flag on the Core user, which must be unset again to return to small blocks) and can estimate fees with the bigBlockGasPrice RPC method. One more detail worth knowing: the on-chain mempool only accepts the next 8 nonces per address, and prunes transactions older than a day.
Risks and gotchas
One chain, two surfaces
Because Core balances and EVM balances are separate, a smart-contract exploit on the EVM side does not automatically drain your HyperCore perps margin, which is protective. The flip side is that capital sitting in an EVM contract does not back your Core positions either. Move only what a given activity needs, and treat the two surfaces as distinct pools when you size risk.
Throughput and gas are still maturing
The intentionally limited launch throughput means gas can spike under load and large deployments belong on big blocks. This is a known, temporary stage that the team is rolling back gradually, but build it into your expectations today rather than assuming Ethereum-scale headroom.
Bridges are separate trust assumptions
The native, lowest-trust path onto the HyperEVM is to deposit to HyperCore and transfer across with the in-app button. Third-party bridges add their own smart-contract and operational risk on top, and a centralized exchange may support sending HYPE to your HyperCore spot balance but not to the HyperEVM. Confirm support, and always send a test transaction the first time.
Onboarding checklist
Add the network — chain ID 999, RPC https://rpc.hyperliquid.xyz/evm, currency HYPE, verified from the official docs.
Get HYPE for gas — buy with USDC on Hyperliquid, or bridge in; keep a buffer on both Core and EVM.
Move funds with the in-app Transfer button — the safest route between HyperCore and the HyperEVM.
Never send a non-HYPE token to 0x2222...2222 — and test every new route with a tiny amount first.
Use big blocks for large deploys — opt in with usingBigBlocks, then switch back to small blocks.
Educational content, not investment or financial advice. Interacting with smart contracts and bridges carries risk, including total loss of funds. Network parameters such as chain ID, RPC, gas, and block limits can change; always verify against the official Hyperliquid documentation before acting.
