Overview

The Gas.zip gas refuel bridge supports over 300+ destination chains and 25 source chains. The primary function from a user's perspective is depositing, where you send native assets to a Gas.zip EOA address along with specific calldata to distribute funds among your desired destination chains.

Depositing to Gas.zip (v2)

Each inbound source chain has a designated EOA address that can accept the chain's native gas asset (e.g. ETH, AVAX, BNB, MATIC) between $0.25 USD and $50.00 USD. Gas uses the CoinGecko API for real-time coin price calculations.

To make a deposit, you must include calldata specifying the destination chains and target recipient address. The destination address can be different from the sending address. The destination chain IDs are not the native chain IDs of each blockchain, but internal IDs designated by Gas.zip. Please see Chain Support for this list of chain IDs.
