Destination chains need gas funding because a bridged token balance does not include the native coin required to transact there. Fund that balance, or choose a route that funds it, and a wallet can arrive on Base, Arbitrum, or another network ready to swap, approve, lend, or send.
The trap is easy to miss. Imagine moving 100 Circle USDC from Ethereum to Arbitrum. The source transaction costs ETH, and the bridge transfers the USDC across. Once the destination balance appears, however, the wallet may still hold zero ETH on Arbitrum. The money has arrived, but the wallet cannot submit the next transaction.
What the bridge actually delivers
A bridge moves an asset and coordinates a message; it does not move a wallet’s ability to pay for future transactions. In a lock-and-mint design, USDC is locked on the source chain, a message or attestation proves that event, and a destination contract mints or releases the corresponding USDC to the recipient. In a liquidity network, a relayer may advance the destination USDC and later rebalance against the source-side deposit. The settlement model changes, but the gas problem remains.
The destination transaction still needs the chain’s native gas asset. On Arbitrum and Base that is ETH; on BNB Smart Chain it is BNB; on Polygon it is POL. USDC cannot normally pay for an ordinary wallet transaction simply because it has a dollar value. The wallet needs native balance to call a token contract, set an allowance, or transfer the received asset.
This is why “received” and “usable” are different states. The bridge contract can deliver USDC to an address without giving that address any ETH. The destination message may be valid and the token balance correct, while the user is stranded until someone sends a small amount of native gas.
How destination gas funding works
A destination gas top-up is a second asset leg attached to the bridge fill. The bridge still moves the main asset, such as USDC. The route also prices a small amount of the destination chain’s native token and arranges for it to reach the recipient.
In a typical flow, the user approves the source token and signs one bridge transaction. A relayer or solver pays for the destination-side transaction, using its own native-token inventory. When the destination fill executes, the recipient receives the bridged USDC and a small ETH, BNB, or POL transfer. The relayer later recovers its cost through the quoted fee, a deduction from the output, or the economics of the route.
The important distinction is that the gas token actually changes hands. It is not merely a gas estimate displayed in the interface. The source-side fee may be denominated in USDC, but the destination wallet ends with native gas. That is what makes a subsequent approval or swap possible.
Some systems instead use a destination contract to bundle the token delivery with a call, such as depositing the output into a DeFi protocol. In that case, the relayer funds the transaction and the user may never receive native gas at all. The action succeeds because the relayer paid for it, not because the wallet was topped up.
That is the practical ParaSwap question: which route leaves the recipient able to act, not merely which quote displays the biggest token number. The route-specific reference is at quora.com.
When the answer changes
The common case is a bridge followed by an action chosen later. For that case, destination gas funding is the cleanest operational choice. Check that the quote explicitly includes a top-up, or reserve native gas on the destination before the bridge completes. Do not assume that a “gasless” label means the wallet will receive gas.
Gasless intent routes solve a different problem. In 1inch Network Fusion+, the user signs an off-chain intent while resolvers fund execution on both chains. The resolver supplies the destination asset and pays the transaction gas, so the user can complete the specified cross-chain swap without holding the destination coin. This is gas abstraction, not necessarily a native-token deposit. If the user wants to make another transaction afterward, the wallet may still need gas.
Circle’s CCTP Forwarding Service shows another variation. A source-side USDC burn carries forwarding instructions, and the service submits the destination mint transaction. The recipient does not have to sign that mint transaction or hold destination gas for it. The forwarding fee is paid from the source-side flow, but the resulting USDC still does not automatically make later wallet actions possible.
That distinction has become more important in 2026 as infrastructure has moved gas handling into APIs and smart-account flows. 0x Protocol’s Gasless API now accepts signatures from ERC-4337 smart wallets, while its cross-chain tooling has expanded native USDC routes between Solana and EVM networks through CCTP V2. These developments reduce the number of times users must manually preload native tokens, but they also make the execution model worth inspecting: who submits the destination transaction, who pays for it, and whether any gas remains in the recipient’s wallet.
Before signing, identify the destination token contract, the destination chain’s native gas asset, and the post-bridge action. If the action is included in the route, a relayer may handle the gas. If the asset simply lands in your wallet, arrange a top-up or keep a small native balance there. A token amount alone is not an execution plan.
- Bridge for later use: fund destination gas or enable an explicit gas top-up.
- Bridge and execute immediately: a relayer or intent route can pay for the destination call.
- Compare quotes: inspect the asset output, gas treatment, fees, and recipient balance separately.
The useful verdict is simple: destination gas funding is what turns cross-chain delivery into a usable balance. Choose whether that funding arrives in the wallet or is consumed by a sponsored execution, then judge the route on that basis.
