Unit Protocol: How to Deposit Native BTC, ETH & SOL to Hyperliquid

Unit

What Is Unit Protocol?

Hyperliquid settles everything in USDC, which is great for perpetual futures but leaves an obvious gap: there is no native Bitcoin, Ethereum, or Solana sitting on the exchange. If you want spot BTC on Hyperliquid, something has to carry real Bitcoin from the Bitcoin network onto HyperCore. Unit (branded as Hyperunit, at hyperunit.xyz) is the piece that does that.

Unit is the asset tokenization layer for Hyperliquid. It runs a lock-and-mint bridge: you send a native asset on its home chain, Unit locks it, and a matching token is minted to your Hyperliquid account as a spot balance you can trade, use as collateral, or withdraw back to the origin chain. It is what lets a Bitcoin holder move real BTC onto Hyperliquid without touching a wrapped-token issuer or routing through a centralized exchange.

Per Unit's own homepage, the bridge has settled well over $14 billion in lifetime deposits and a similar figure in withdrawals across more than a million operations. This is not a fringe tool; it is one of the main on-ramps into the Hyperliquid spot ecosystem.

Which Assets Does Unit Support?

Unit launched with the three assets most people want on a spot exchange and has been adding more over time. The confirmed core is Bitcoin (uBTC), Ethereum (uETH), and Solana (uSOL).

Beyond those, Unit has bridged in a rotating set of Solana-based tokens and newer assets. Names like FARTCOIN, PUMP, SPX6900, BONK, and Plasma (XPL) have appeared as deposits, withdrawals, and spot trading went live for each. The list changes often, especially on the Solana memecoin side, so treat any snapshot as a point in time and check the live asset list in the app before you plan around a specific token.

The most recent addition to make noise was ANSEM, the Solana memecoin tied to the trader of the same name. Its spot trading, deposits, and withdrawals went live on Hyperliquid in July 2026, bridged in through Unit's Solana support. It is a good illustration of how quickly a token can go from a Pump.fun launch to a native Hyperliquid spot market once Unit supports the chain it lives on.

How Deposits Work

The deposit flow is a classic lock-and-mint, and the mechanics matter because a mistake at the wrong step can lose funds.

uBTC, uETH, uSOL: What the Tokens Actually Are

The tokens Unit mints are prefixed with a lowercase "u" (uBTC, uETH, uSOL), and each is a 1:1 claim on the native asset Unit is holding for you. In Hyperliquid's spot order books and in the HyperEVM DeFi protocols that accept them, the same assets show up as uppercase tickers: UBTC, UETH, USOL. They are the same thing. "uBTC" is the branding and "UBTC" is how it reads as a market ticker.

This is why Unit sits underneath so much of the ecosystem. When Felix Protocol lets you post UBTC as collateral to mint feUSD, or when HyperLend accepts UBTC in a lending market, that Bitcoin got there through Unit. The same balance you can trade on spot is the one you can deploy across HyperEVM DeFi.

How Withdrawals Work

Withdrawing reverses the process:

1. Select the asset and enter a destination. On the withdraw screen, choose your uAsset, the amount, and the address on the native chain where you want the real asset sent.
2. Sign on Hyperliquid. You sign a Hyperliquid transaction that burns or sends the uAsset back to Unit. Hyperliquid finalizes this in roughly ten seconds.
3. Guardians release the native asset. Once Hyperliquid finalizes, the guardian network signs and broadcasts the transfer of the real asset to your destination address on its home chain.

Withdrawals are generally faster than deposits because you are not waiting on multiple source-chain confirmations up front, though the guardian step and native-chain broadcast still take a few minutes.

The Guardian Security Model

Any bridge is only as trustworthy as its custody design, so this is the part worth understanding before you move real money.

Unit secures assets with a 2-of-3 MPC threshold signature scheme (TSS). Three guardians each hold an independent share of the signing key, generated through distributed key generation. A full private key never exists in one place; the shares are combined only transiently, inside secure enclaves, at the moment a signature is needed. Any critical action (minting a uAsset, releasing a native asset) requires at least two of the three guardians to agree.

Around that core, Unit's docs describe several safeguards: key shares encrypted at rest with KMS, out-of-band identity checks between guardians, end-to-end encrypted guardian-to-guardian communication so relay servers never touch key material, full operation logging, and circuit breakers that pause the system if a guardian detects conflicting or abnormal activity.

Fees and Confirmation Times

Unit's fee model is refreshingly simple: there is no Unit protocol fee. You pay only the network fees for the two underlying transactions, your deposit on the source chain plus the transaction the guardians broadcast on withdrawal. Unit exposes a live fee-estimation endpoint, so the app shows you the current rate and ETA before you commit.

The figures below are illustrative snapshots from Unit's fee endpoint. They move with network conditions, so read them as ballpark, not fixed:

How It Shows Up in the Hyperliquid App

You do not have to go to a separate site to use Unit. There are two entry points into the exact same rails:

• app.hyperliquid.xyz lists the Unit-powered assets right in the spot deposit flow. Pick BTC, ETH, or SOL and Hyperliquid surfaces your Unit deposit address inline, so you never leave the trading interface.
• hyperunit.xyz offers the same deposit and withdraw flows directly, plus the recent-operations feed and fee estimates.

Either way, the deposit address is generated by Unit's guardian network and bound to your Hyperliquid account, and the resulting balance lands in your Hyperliquid spot wallet as UBTC, UETH, or USOL. If you have never funded a Hyperliquid account before, start with our guide to depositing USDC and the beginner walkthrough, then come back to Unit when you want native spot assets alongside your USDC.

You will need a connected wallet either way. MetaMask or Rabby both work fine with the Hyperliquid interface.

Risks and Caveats

Unit is genuinely useful infrastructure, but it is a bridge, and bridges concentrate risk. Keep these in mind:

• Custody and bridge risk. Your funds sit behind a 2-of-3 guardian set. Collusion or compromise of two guardians is the theoretical worst case. There is no publicly confirmed audit, and the guardians are not named, which is a real trust assumption rather than a formality.
• The irreversible-minimum trap. BTC below 0.0003 is gone for good. Deposit addresses are asset- and user-specific, so sending the wrong asset or using the wrong chain can also mean permanent loss.
• Confirmation delays and circuit breakers. Bitcoin deposits wait on two confirmations, and the guardians' circuit breakers can pause operations, delaying a withdrawal exactly when markets are moving.
• Thin liquidity on newer assets. Many of the freshly bridged memecoins carry extreme volatility and shallow spot books. The bridge working perfectly does not make the token a good trade.
• Token and airdrop speculation. You will see chatter about a future "UNIT" token or airdrop for bridge users. Nothing official is confirmed. Do not bridge funds you would not otherwise move on the assumption that it earns you an airdrop.

Where Unit Fits in the Hyperliquid Ecosystem

Unit is one of those pieces of plumbing you stop noticing once it works, but almost every "native asset" experience on Hyperliquid runs through it. Spot BTC, ETH, and SOL trading, UBTC collateral on Felix and HyperLend, and the steady drip of new spot listings all depend on Unit carrying the real asset onto the chain first.

That makes it a natural companion to the rest of the HyperEVM DeFi ecosystem. USDC gets you into perps; Unit gets you into everything denominated in actual crypto. Once your BTC or ETH is on Hyperliquid as a uAsset, it behaves like any other spot balance: tradable, usable as collateral, and redeemable back to its home chain whenever you want out. For traders who want to keep Bitcoin exposure while trading perps in the same account, or who want to lend spot ETH into a HyperEVM market, Unit is the bridge that makes it possible without leaving the ecosystem.
