Never Get Stranded With No Gas: Automatic Destination Gas Top-Up
Bridge to a new chain and land with zero native gas token — a common trap. Here's the one-checkbox fix built into every cross-chain swap on Blockchains.Click.
Bridge into a new EVM chain holding only the token you asked for, and you can hit an immediate wall: you can't move, sell, or do anything with it without a small amount of that chain's native gas token first — and you don't have any. It's a common, avoidable trap.
Quick facts
- One checkbox on the swap page, available for any non-Solana destination
- Delivers roughly $2 of the destination chain’s native gas token by default, funded from the same swap
- Automatically skipped when it would be pointless — e.g. your destination token already IS that chain’s gas token
- No separate transaction or extra signature — it’s part of the same quote you already confirm
How it works
This isn't a separate custodial balance or a second transaction — it's a real feature of the routing engine (Relay) this app already uses for cross-chain swaps. When you check "Destination gas top-up," the quote request asks Relay to bundle a small amount of the destination chain's native currency into the same fill that delivers your requested token. Relay's solver network handles sourcing it, priced into your one quote, delivered in your one signature.
It's opt-in and automatically inapplicable in cases where it wouldn't make sense — for example, if you're bridging directly into a chain's own native token, there's nothing to "top up" since you're already receiving gas currency.
Where to find it
Open the swap page, pick a source token and a non-Solana destination, and the gas top-up checkbox appears in the quote summary automatically. No separate page, no extra setup — try a cross-chain swap and look for "Destination gas top-up" once you've picked chains.
