# Gas, speed, and fee tokens

Gas pays for EVM computation and inclusion. WalletChan estimates it, applies
network-specific headroom, and keeps the fee decision next to Confirm.

## Local gas tiers

Private-key, seed-phrase, and eligible Ledger transactions offer **Slow**,
**Standard**, **Fast**, and **Custom**. Custom mode exposes gas limit,
priority fee, and max fee relationships with validation.

A dapp-provided gas value can act as a floor where applicable. MegaETH uses the
chain's non-standard gas estimate rather than trusting a standard-wallet gas
value. Bankr manages gas remotely and shows a read-only explanation.

## Native MAX

For native transfers, MAX reserves buffered gas plus fee headroom. It is
intentionally lower than the full native balance. Token MAX can use the full
token balance while leaving the chosen gas asset separate.

## Pay gas with a token

On eligible networks and accounts, open the fee-asset picker. It shows supported
tokens, balance, maximum quoted fee, logo, and stablecoin fiat equivalent where
available. Native currency remains the default.

Token-paid gas uses a bounded ERC-4337/Pimlico route and a compatible
WalletChan EIP-7702 delegate.

| Account | Fee-token eligibility |
| --- | --- |
| Private key / seed | Existing or reviewed first-use WalletChan delegation |
| Ledger / view-only | Not supported |
| Safe | Eligible private-key/seed executor at execution quorum |
| Bankr | Only when the official delegate is already active |

Fee tokens are unavailable for contract deployments, force inclusion, or
foreign/custom delegates. The token catalog differs by chain and quote
availability.

## Quotes and failures

Fee quotes expire and are not silently reused. If a quote or preparation fails,
choose Retry or return to native gas. An insufficient-token message may suggest
reducing a transfer amount or choosing the native token.

## L2 fees

OP Stack transaction details can show the separate L1 data fee. Base,
Optimism, and Unichain can also use fast receipt polling when the selected RPC
supports their preconfirmation path.
