Gas Token

Overview

A gas token funds the fee charged for network resources. ETH pays Ethereum mainnet gas, while other networks use their own native assets or allow configured tokens through protocol-level fee abstraction, smart accounts, or paymasters.

The fee asset should not be confused with historical contract tokens that attempted to store gas refunds. On many EVM networks, an ERC-20 balance cannot directly pay base-layer gas even if the token has substantial value. Wallets and payment platforms must identify the fee token for each chain, maintain enough spendable balance, and calculate decimals and pricing correctly. Bridged versions may not substitute for the native asset. When users pay fees in another token, the application should disclose conversion rate, markup, sponsor, and maximum charge.

A ticker, logo, or project name is not sufficient because unrelated assets and bridged representations can use similar branding. Gas Token should be identified by its issuing network, contract or native-asset identifier, decimals, supply authority, and functional role. The rights associated with Gas Token may involve fees, staking, governance, access, redemption, or incentives, but those functions should be verified independently. Holding a token does not automatically create ownership, revenue, legal claims, or control over the underlying protocol.

They may not be usable for the original network function and should be treated as separate assets for accounting and risk management. Wrapped or bridged forms of Gas Token introduce additional contracts, custodians, validators, liquidity, and redemption paths. Implementation note: Gas tokens fund execution, so integrations must distinguish the chain’s spendable native fee asset from wrapped or bridged representations.
