Get Started with Supersmooth: Wallets, Networks, Products

Connect your wallet, pick a network, and preview your first Supersmooth position. Overview of supported wallets, networks, products, and fees.

Supersmooth is a self-custodial DeFi position management platform. Connect a wallet, browse markets across integrated protocols, preview any position with a full simulation, and confirm. Every action is a single transaction, and your positions live in Safe smart accounts you own.

Onboarding in four steps

1. Connect a wallet

   Confirm the correct network is selected. The Supersmooth app prompts a network switch when one is needed.

2. Browse markets

   Filter Supersmooth markets by collateral, debt asset, network, protocol, liquidity, oracle, or protocol characteristics such as unified versus isolated liquidity, permissionless markets, partial liquidations, immutable contracts, and governance model. Each market displays maximum multiple or maximum LTV, current rates, available liquidity, and supported automations.

3. Preview the position

   Enter a deposit amount and, for Multiply, a target multiple. Before you sign anything, Supersmooth simulates the complete post-action position, including liquidation price, net APY, price impact, and every fee.

4. Approve and confirm

   Your first position of a given type deploys that position type’s Safe in the same flow. Token approvals are granted to your own Safe, never to Supersmooth.

Every position-altering action in Supersmooth, including open, adjust, close, refinance, and automation setup, shows the same simulation-first preview before signing.

Supported wallets

Supersmooth supports MetaMask, Phantom, Rabby, and other leading EOA wallets. Hardware wallets include Ledger and Trezor. Existing Safe wallets are supported, as are all other major wallet providers.
