Connect to Hyperliquid
The Strategy Builder runs your strategies on Hyperliquid, the exchange where the orders are actually placed. Synchronicity is currently on Hyperliquid testnet, so a deployed strategy trades test funds with no real value, the same flow that will trade real funds at the mainnet launch. Before you can deploy anything, you link your own Hyperliquid account and grant Synchronicity permission to trade it. This page walks the link from a fresh wallet to a connected account that is ready to deploy.
Before you start
You need one thing to begin: a supported wallet. Synchronicity supports MetaMask and Rabby, or you can sign in with email to use an embedded wallet (via Privy). You sign in and authorize trading with it, and Synchronicity never holds your funds. On testnet the funds are provided for you, so there is nothing to deposit.
Synchronicity currently runs on Hyperliquid testnet. Every order, position, and liquidation a deployed strategy creates uses test funds and settles on Hyperliquid testnet, so nothing here puts real money at risk. The mechanics are identical to mainnet, which makes this the place to learn how leverage and liquidation behave before they are real. Read Leverage, Margin, and Liquidation as you practice.
Connect your wallet and choose your account
Go to testnet.synchronicity.xyz and click Connect account. Choose how you sign in: connect MetaMask or Rabby, or enter your email to use a wallet Synchronicity creates for you.
The first time you connect, you sign a message that proves the wallet is yours. This is a signature, not a transaction. It costs nothing and moves no funds.
You then make a one-time account choice:
- Keep your current Synchronicity account. Continue with your existing address. Hyperliquid supports every wallet Synchronicity supported before.
- Migrate to another wallet. Move your testnet activity and referrals to a different address. Choose this to use an existing Hyperliquid account, or a fresh wallet, without losing your progress.
After you choose, 250 testnet USDC lands on the selected wallet. That is enough to start building and deploying, and Synchronicity never holds it for you.
Signing in and choosing your account does not yet authorize any trading on Hyperliquid. That is the next step, and it is deliberately separate.
Getting more test funds
Top Ups inside the app are limited. If you run out and want to keep trading, you have two options:
- Hyperliquid faucet. Claim 1,000 testnet USDC from Hyperliquid’s testnet drip . This one requires having funds on Hyperliquid mainnet.
- Open a ticket. Reach out to the team and they will coordinate sending you more testnet USDC.
When mainnet launches, this changes: you will fund your own Hyperliquid account with real USDC instead of receiving test funds. See the Hyperliquid documentation for funding a real account.
Link and approve your Hyperliquid account
With your wallet connected, you authorize Synchronicity to trade your Hyperliquid account. Open the Hyperliquid connection flow and click Connect Hyperliquid. There are two approvals, each a signature from your wallet.
The Hyperliquid setup: approve the trading agent, then the builder-code cap.
- Approve the trading agent. Synchronicity uses an agent wallet: a dedicated key that acts on your Hyperliquid account on your behalf, and approving it is what lets a deployed strategy trade. Hyperliquid’s agent approval is broad and matches the access other Hyperliquid interfaces use: once approved, the agent can do anything you can on the account except withdraw your funds. The agent key itself stays encrypted on Synchronicity’s backend and is never shared with your browser.
- Approve the builder code. Hyperliquid builder codes let an interface attach a small, capped fee to the orders it submits. You sign a one-time approval for Synchronicity’s builder-code cap of 10 basis points. The cap is the ceiling you authorize, not a charge taken up front. See Trading Fees for how this builder fee stacks with the exchange’s own trading fee.
The approvals are signed on the Hyperliquid network, so your wallet needs to be on it. If it is on a different network, the flow prompts you to switch before it can sign. Approve both, and the connection completes.
An approval is a permission, not a transfer. Signing the agent and builder-code approvals authorizes Synchronicity to place orders from your account. It never moves your funds off Hyperliquid or out of your control. You can revoke the agent approval at any time, which stops future Synchronicity orders on that account.
Confirm you are ready
You are ready to deploy when three things are true.
- Your wallet shows as connected in the app.
- Your Hyperliquid status reads Approved, with the agent and builder code both signed.
- Your Hyperliquid testnet balance shows in the app and on the Order node, so a strategy has test funds to trade.
Treat testnet like the real thing. Watch how a strategy behaves on live fills and learn what each leverage and size choice does, because the same flow trades real funds when mainnet launches. The habits you build now are the ones that protect you then.
