Phantom, a leading crypto wallet with around 25 billion dollars in self-custody assets, launched its latest update, introducing native perpetual trading. The wallet integrates Hyperliquid builder codes to tap into Hyperliquid blockchain's trading infrastructure, allowing users to trade perpetuals directly within the Phantom interface. Launch seamlessly on Hyperliquid with high-performance Hyperliquid RPC nodes optimised for stability.
What are Hyperliquid Builder Codes?
Hyperliquid builder codes allow anyone to build a platform that accepts Hyperliquid trades on a user's behalf through a custom interface. In the case of Phantom, users can directly trade perpetuals through Phantom wallet's interface instead of having to interact with the Hyperliquid blockchain. Builder codes allow custom platforms to charge fees of up to 0.1% on perpetual trades and 1% on spot trades, as defined by Hyperliquid’s protocol rules.
How Phantom Integrated Builder Codes
In Phantom’s case, builder codes serve as the foundation for enabling perpetual trading directly inside the wallet. Builder codes allow Phantom to relay trades to Hyperliquid blockchain on its HyperCore layer, letting users open and manage positions without needing to leave the app or interact directly with the Hyperliquid interface. Everything happens within the Phantom wallet.
The fee structure for trading through Phantom is straightforward. Phantom charges additional fees on opening and closing positions, while depositing and withdrawing funds only incur existing fees. Phantom does not appear to charge additional fees beyond what’s shown in the interface, although conversion-related costs (e.g., SOL to USDC) may apply.

Phantom Perpetual Trading Features
First-time users undergo an onboarding flow that may include setting a default leverage or preferred trading parameters. Users can also easily enable auto-close features, such as stop loss and take profit targets for each position.
If users have previously used Hyperliquid blockchain with their Phantom wallet, their existing perps balances and positions automatically sync inside Phantom. No extra setup is needed. Users can instantly view open trades, performance, and available margin.
How Does Phantom handle funds?
The Phantom app simplifies depositing and withdrawing funds. Users deposit by sending SOL, which Phantom automatically swaps to USDC and bridges into their Hyperliquid perps account. Withdrawals work in reverse, converting USDC back into SOL and bridging it to the wallet on Solana. All of this happens within the Phantom interface without requiring manual bridging or separate apps.
Phantom’s integration of builder codes effectively turns the wallet into a full-featured perps trading platform, built directly on top of Hyperliquid’s HyperCore layer.
Closing Remarks: Hyperliquid Builder Codes
Phantom’s integration with Hyperliquid blockchain’s builder codes shows how wallets can go beyond self-custody and offer advanced trading features like perpetual trading. By embedding perps trading directly inside its interface, Phantom makes it easier for users to access Hyperliquid’s deep liquidity and advanced execution while keeping the process simple and mobile-friendly. As more apps adopt builder codes, we will likely see more custom trading interfaces that make on-chain trading faster and more accessible for everyday users.
