Aug 03, 2026
What Is Smart Gas in BloFin Wallet?
Smart Gas is BloFin Wallet's prepaid gas account that automatically covers transaction fees across supported networks. You can also pay gas with USDT or USDC via gas sponsorship β so you do not always need the native token (ETH, BNB, SOL, etc.) on each chain.
β οΈ Smart Gas is available only with a Passkey Wallet. Mnemonic (seed phrase) wallets cannot use Smart Gas.
Requirements
To use Smart Gas in BloFin Wallet you need:
- A Passkey Wallet (Face ID / Touch ID, no seed phrase)
- A funded Smart Gas balance
If you currently use a Mnemonic Wallet, create or switch to a Passkey Wallet to unlock Smart Gas.
Why Smart Gas Matters
On most blockchains, every swap, transfer, or on-chain action needs a gas fee. Without the right native token, the transaction fails. With a Passkey Wallet, Smart Gas lets you:
| Benefit | Description |
|---|---|
| β½ Prepay once | Fund your Smart Gas balance once and use it across supported networks |
| π΅ Pay with stablecoins | Cover fees with USDT / USDC instead of hunting for native gas tokens |
| π Less friction | Complete swaps, bridges, and other on-chain actions more smoothly |
