Smart Gas removes a critical friction point

The gas fee problem has been a persistent obstacle to CEX-to-wallet migration. Users withdraw tokens, attempt a transaction, and hit a wall when they don’t have the native coin to cover fees.

Smart Gas eliminates this entirely by enabling fee payment in stablecoins. It's a simple solution to a widely-recognized pain point, and it makes the transition to self-custody measurably smoother for newcomers.

Smart Gas: friction killer

• Makes ditching CEX for self-custody MUCH easier
• Solves one of the most common UX pain points, making our app feel smoother - especially for those who are only just discovering self-custody
• Scenario: a user withdraws tokens to their new wallet, attempts to make a transaction, and discovers they can't. The transaction requires gas fees paid in the network's native currency—ETH on Ethereum, BNB on BNB Smart Chain, MATIC on Polygon—and they have none.
• We’re eliminating that barrier entirely by allowing users to pay for their gas with stablecoins instead of native tokens.
• Example: Alice withdraws 100 USDT from Coinbase to her Tangem Wallet on the Ethereum network. She wants to send 50 USDT to Bob, but she has no ETH on Tangem to pay the gas fee. With Gasless Transactions, the app detects her USDT balance and offers to pay the fee in USDT. Alice confirms and signs the transaction, and 50 USDT is sent to Bob while ~$0.80 in USDT is deducted as the network fee. She never needed to acquire ETH.

DO say: Smart Gas helps you onboard onto self-custody in the most simple way. If you want to just use stablecoins to earn interest via the secure Tangem App, you don’t have to understand the nuances of using different blockchains.

DON’T say: Smart Gas means you can pay for transactions without ETH

Introducing Smart Gas: Pay Network Fees with Stablecoins in Tangem Wallet

Smart gas transactions are now available in Tangem Wallet across Ethereum, BNB Smart Chain, Polygon, Arbitrum One, and Base.

Users migrating from centralized exchanges to self-custody wallets consistently hit the same obstacle: they withdraw tokens to their new wallet, attempt to make a transaction, and discover they can't. The transaction requires gas fees paid in the network's native currency, ETH on Ethereum, BNB on BNB Smart Chain, MATIC on Polygon, and they have none.

This isn't a minor inconvenience. The user now needs to acquire a small amount of native tokens just to move their own assets. That means finding an exchange that supports small purchases, paying withdrawal fees that may exceed the amount needed, or finding a faucet or friend who can send them enough to get started. For many users, especially those new to self-custody, this is where they give up.

We’re integrating smart gas transactions to eliminate this barrier entirely.

What is a smart gas transaction?

Smart gas transactions allow users to pay network fees using popular stablecoins instead of native tokens. When you have USDC or USDT in a supported network, you can use it to cover transaction fees directly.

Example: Alice withdraws 100 USDT from Coinbase to her Tangem Wallet on the Ethereum network. She wants to send 50 USDT to Bob, but she has no ETH on Tangem to pay the gas fee. With Smart gas transactions, the app detects her USDT balance and offers to pay the fee in USDT. Alice confirms and signs the transaction, and 50 USDT is sent to Bob, with ~$0.80 in USDT deducted as the network fee. She never needed to acquire ETH.

Supported Networks and Tokens

Smart gas transactions are available on major EVM networks that have implemented EIP-7702 (Pectra upgrade). We've selected fee tokens based on liquidity, predictable transfer gas costs, and widespread adoption; primarily USD-pegged stablecoins that users are most likely to hold after withdrawing from exchanges.
