Using the app
Deposits and sign-in
Connect a Cardano, Solana or Ethereum wallet, or sign in with API keys, and fund your account in the app.
Ways to sign in
| Method | Use it when | Builder fee |
|---|---|---|
| Builder Connect (wallet) | Normal use. Your Cardano, Solana or Ethereum wallet signs a challenge. | Charged |
| API wallet keys | The account owns the builder code (Strike refuses to connect an account to its own builder), or for bots. Create keys at app.strikefinance.org/api-keys(opens in a new tab). | Not charged |
Staying signed in
Both methods offer "Remember on this device". It stores the trading key in this browser's local storage, unencrypted, and signs you back in after a refresh. Disconnect forgets it. Deposits on a restored session ask the wallet to reconnect.
Depositing
- Choose the assetThe panel shows your wallet balance for it and the native coin for fees.
- Type the amountPlain units, for example 16 for 16 USDC. The panel shows the raw amount sent to Strike and refuses more than you hold.
- Get QuoteStrike returns the USD value and builds the transaction.
- Deposit with walletEthereum: the wallet is switched to Ethereum mainnet, then asks twice (token approval, then deposit). Solana: one signature, sign within about 60 seconds. Cardano: one signature; Vektor adds the witness and submits.
- WaitCredit usually appears in 2-5 minutes, after block confirmations. The balance updates by itself.
Withdrawing
Withdrawals need your wallet's signature, and API-wallet keys cannot withdraw by design. Use the Withdraw panel while signed in with a wallet, or the Strike app.
