BloFin Wallet - SmartGas
April 23, 2026 at 03:34 PMWhat is SmartGas
SmartGas is a convenient gas fee management and payment solution provided by BloFin Wallet.
With SmartGas, you can deposit USDT or USDC into your SmartGas balance once, and gas fees across all supported chains will be paid automatically — no need to stock up on native tokens for each chain separately.
Traditional Wallet | SmartGas | |
Gas fee token | Native token per chain (ETH, BNB, MATIC…) | USDT or USDC |
Setup required | Top up each chain separately | Deposit once |
Multi-chain support | Manage per chain | One balance for all supported chains |
Note: SmartGas is currently available for Passkey wallets only.
Why Use SmartGas
- One balance, all chains: No need to hold ETH, BNB, MATIC, or other native tokens separately. One SmartGas balance covers gas across all supported chains — saving you the swap fees and slippage that come with acquiring native tokens.
- Automatic, zero friction: When you send assets, swap, or interact with a DApp on any supported chain, gas fees are deducted automatically from your SmartGas balance. No manual switching, no extra steps.
- Clear spending records: Every gas deduction is logged into "Recent Activity" with the chain name, transaction hash, and amount — easy to track at a glance.
