Backend strategies cannot prompt MetaMask when you're asleep. The Vant8 Blockchain Wallet is an opt-in custodial wallet on each supported chain that signs unattended transactions on your behalf — for Hyperliquid perps, scheduled DEX execution, and any on-chain strategy bot that needs to act without you. Vant8 charges no fee on this path — you pay network gas and the on-chain AMM fee only. Vant8 holds the key material; that is the trade-off you make for hands-off automation. You can withdraw out at any time.
A unique address is derived per-user from server-side master key material. The same address is reused across every supported chain so you fund one address per network.
The signing key for your derived wallet is encrypted with AES-256-GCM before it touches storage. Production deployments use cloud KMS for the unwrap so plaintext keys never live in the application database.
Send funds from your own wallet to the derived address on the chain you want to automate on. A deposit-monitor picks up the inbound transfer once it confirms on-chain.
Strategies and scheduled flows trigger the wallet to build, sign, and broadcast the transaction — no MetaMask prompt, no manual click. The dashboard shows every transaction and its on-chain status.
If the action has to happen while you are not at the keyboard, it runs through the Blockchain Wallet.
Your Hyperliquid account is the same EVM address as your Blockchain Wallet. Deposits bridge through Arbitrum, perp orders are signed automatically by the same derived key — no MetaMask prompt per trade.
Time-based and threshold-triggered on-chain actions that the platform has built to run while you are away. The wallet's signing path is the only way Vant8 can broadcast on-chain transactions without you in the browser to approve each one.
Not every on-chain feature on Vant8 routes through the Blockchain Wallet. CoW Protocol limit orders and Yield Farming actions are user-initiated and signed by your Connect-Wallet EOA — that's deliberate, so you authorise each one yourself.
When you place a CoW limit order, your connected wallet provides the EIP-712 signature. The Blockchain Wallet is not involved — by design, because a limit order is a user decision that you should consciously sign.
Farming approvals, deposits, claims, withdrawals, and remove-liquidity calls are all signed by your connected wallet. Vant8 never holds your LP tokens or reward tokens, and the Blockchain Wallet is not on this path.
On-chain automation runs into a specific failure mode — the wallet has funds but not enough native gas to move them. Vant8 monitors the native balance on every supported chain and, when it drops below the chain's threshold, swaps a small amount of your USDT to native gas at a per-chain DEX. Unattended flows don't stop for want of gas.
A background job checks your wallet's native token (BNB on BSC, ETH on Ethereum / Arbitrum / Optimism, POL on Polygon, AVAX on Avalanche) on a regular interval. Each chain has its own minimum and target balance.
When the native balance drops below the chain's minimum, a small amount of your USDT is swapped for the native token — using the leading DEX on each chain (PancakeSwap on BSC, Uniswap V3 on Ethereum, QuickSwap on Polygon, Camelot on Arbitrum, Velodrome on Optimism, TraderJoe on Avalanche).
The trigger threshold sits well above the minimum gas needed to actually execute the refill swap. The wallet refills before it runs out — so it never gets stuck with 'need gas to buy gas.'
You get a notification when a refill happens, and an alert if the wallet's USDT balance isn't enough to cover the refill. Top up the USDT balance and the next cycle resumes automation.
HD derivation produces the same EVM address on every chain, so you only have one wallet identity to fund across networks.
Everything you need to manage the wallet lives in the dashboard. Wallet generation and key custody stay on Vant8's side by design — that's what makes unattended automation possible.
The dashboard shows your derived address, live balance per chain, and a full transaction history — every transaction signed on your behalf is logged with its on-chain status.
Initiate a withdrawal from the dashboard and the funds move to any external address you control on the same chain. There is no lock-up beyond the on-chain confirmation time.
Convenience and custody are a trade-off. The Blockchain Wallet's whole reason to exist is unattended automation, which requires Vant8 to be able to sign without you. The four points below describe exactly what that entails so you can decide before enabling it.
This is materially different from your connected EOA. Vant8 controls the signing key — encrypted at rest, scoped to the surfaces you enable, but Vant8-controlled nonetheless. If you want pure non-custodial signing, use Connect Wallet instead and accept that strategies cannot auto-execute.
A compromise of Vant8's master-key infrastructure would compromise the derivation. We isolate the unwrap path through cloud KMS in production specifically to make that infrastructure the hardened surface — but the structural trust is real, and you should price it in.
The Blockchain Wallet today is a single-key model. There is no multi-sig, threshold, or social-recovery scheme. Withdrawal access depends on your Vant8 account access — protect your account credentials and second-factor accordingly.
Vant8 is not a registered custodian and carries no insurance on funds held in derived wallets. The Risk Disclosure covers what this means in practice.
Both surfaces exist for different jobs. Most users end up using both.
A strategy needs to act without you (Hyperliquid perps, on-chain bots, scheduled DCA, auto-rebalancing). You accept Vant8-managed custody in exchange for unattended automation.
You want to sign each action yourself — yield-farming approvals and deposits, CoW Protocol limit orders you place by hand, manual DEX swaps. Your keys never leave your wallet.
