How to deposit crypto on Spinman
A deposit is just a regular on-chain transfer from your wallet (or exchange) to an address we generate for you. Most clear in seconds; Ethereum clears in 1–2 minutes. Total fee is whatever the network charges — Spinman never adds a deposit fee.
The 5-step flow
- Open your Spinman balance page. Sign in with email, click the wallet icon, and open Deposit.
- Pick a network. Solana, Ethereum, BNB, Polygon, Base, Arbitrum, or Tron. Match it to the network you're sending from.
- Copy the deposit address (or scan QR). Each network has its own dedicated address. Don't reuse one across chains.
- Send from your wallet or exchange. Paste the address, choose the same asset (USDT, USDC, SOL, ETH, etc.), confirm.
- Wait for confirmations. Solana / BNB / Polygon / Base / Arbitrum / Tron: seconds. Ethereum: ~1–2 minutes depending on gas.
Picking the right network
This is the only step that trips people up. Two rules:
- Match the network on both ends. If you send USDT on Solana, choose Solana on Spinman. Sending Ethereum-USDT to a Solana address will lose the funds — that's how crypto works, not a Spinman rule.
- Cheapest networks for stablecoins: Solana, Tron (TRC20), Polygon, Base. Avoid Ethereum mainnet unless you already hold ETH there.
From an exchange (Binance, Coinbase, Kraken, Bybit)
- Go to Withdraw on the exchange and pick the same asset (e.g. USDT).
- Choose the same network as the deposit address you got from Spinman.
- Paste the Spinman address. The exchange will show its withdrawal fee — usually $0.20–$1 on Solana / Tron / Polygon, $3–$20 on Ethereum.
- Confirm. Most exchanges auto-approve. Some hold the first withdrawal for ~15 minutes.
From a self-custody wallet (Phantom, MetaMask, Trust)
- Open your wallet, pick the right network (Phantom: Solana / EVM dropdown; MetaMask: top network selector).
- Hit Send, choose the token (USDT, USDC, etc.), paste the Spinman address.
- Confirm. You'll pay only the network gas — usually a few cents on non-Ethereum chains.
Common mistakes (and how to fix them)
| Mistake | What happens | Fix |
|---|---|---|
| Wrong network | Funds may be unrecoverable, or stuck on a chain Spinman doesn't credit. | Contact support before sending more. We can sometimes recover EVM-to-EVM mistakes; cross-VM (Solana ↔ EVM) is usually unrecoverable. |
| Missing memo (Tron / TRC20) | If your exchange requires a memo and you didn't add it. | Spinman addresses are memo-less. Just send to the address. |
| Sent BEP-20 USDT to Ethereum address | Funds land on BNB Chain but the address looks the same. | Open MetaMask on BNB Chain — funds are there. Re-send on the correct network. |
| Deposit not showing after 5 min | Usually Ethereum gas congestion, or wrong network selected. | Check the tx on the block explorer. If confirmed and missing, open chat with the tx hash. |
What gets credited
Native coins (SOL, ETH, BNB, MATIC) are auto-converted to USDb (our 1:1 USD stablecoin balance) at the live market rate the moment they land. You can also hold USDT / USDC and your balance will display in USD anyway. There's no spread or conversion fee.
