For a routine transfer, start with Bungee bridge’s Auto route; compare Manual routes when the amount received, transfer time or bridge choice matters. Bungee draws on multiple bridges and liquidity sources to move assets between blockchains. Choose by what will arrive, what the route will cost and whether you will have gas to use the asset afterward.
How Bungee bridge Builds a Transfer Route
Bungee finds a path from the token in your wallet to the token you want on another network. A path may cross one bridge, or it may swap tokens before or after the cross-chain transfer. That is why selecting the destination token matters as much as selecting the destination network.
The Bungee bridge aggregator compares available paths for your chosen networks, tokens and amount, then presents a quote for what could arrive. A Bungee crypto bridge quote reflects the route available for that particular transfer; change the amount or token and the useful routes may change too. The estimate also depends on liquidity and network conditions when you submit.
Consider someone holding USDC on Ethereum who wants USDC on another network. Bungee can look for liquidity that delivers that destination asset without making the user find and visit each bridge separately. If the requested asset is unavailable on a direct path, the route may need a token swap, which introduces a price and possible slippage.
Auto and Manual Routes Serve Different Priorities
Auto is the simpler way to execute a quoted transfer, while Manual is for inspecting and selecting an available route yourself. These are choices about control over the route. Either can involve a direct bridge or a swap, depending on the tokens and networks selected.
-
Auto — best for a straightforward transfer. You specify the input, destination and recipient, then review the proposed result before signing. It fits an occasional user who mainly cares that the correct asset arrives with few decisions to make. It fits less well when you need to choose a particular bridge or compare several paths side by side.
-
Manual — best for comparing route trade-offs. Available Manual routes let you weigh estimated output, time and the underlying path before choosing one. It fits when a modest difference in received amount matters or you have a reason to prefer a route’s mechanics. It asks for more attention, and a token approval may add an onchain transaction before the transfer.
An approval lets a contract spend a specified token from your wallet for the transaction. Some Auto flows use a Permit2 approval and a later signature; Manual routes can use a conventional token approval. The wallet prompts therefore depend on the token, route and approvals you have already made.
Bridge-Only and Swap Routes Change What Arrives
A bridge-only route moves an asset across networks, while a swap-and-bridge route also changes the asset you receive. This distinction is easy to miss when two tokens share a ticker. Check the destination network and token contract or issuer, especially when choosing between native and bridged versions of a stablecoin.
-
Bridge-only — best when you want the same asset on the destination. It avoids an added market swap and its price impact. It does not fit if the asset you hold lacks a usable path to the version you need on the destination network.
-
Swap-and-bridge — best when the destination asset differs. A route can convert the input before bridging, or bridge first and convert after arrival. It saves a separate swap, but the extra trade can reduce output through fees, price impact or slippage, particularly for a large amount relative to available liquidity.
For example, suppose you start with 1,000 USDC on Ethereum and want USDC on the destination network. An illustrative quote might show 994 USDC arriving by one route and 991 USDC by another that estimates a faster arrival. The before-and-after comparison is 1,000 USDC sent versus the quoted amount of the correct destination token received; the three-USDC difference buys an estimated time saving, which may or may not matter to you.
The Quote and Destination Determine the Final Choice
The useful comparison is what you can do with the asset after it arrives, alongside the quoted amount and time. Route costs can include source-network gas, bridge or liquidity fees, and swap costs; some execution costs are already reflected in an Auto quote. There is no reliable flat fee or completion time for every transfer, so compare fresh quotes for your exact amount.
Before signing, set the source and destination networks, input and output tokens, amount, and recipient address. Read the estimated output, any minimum received amount, the approval request and the route’s estimated time. If the quote changes substantially while you review it, request a fresh one before proceeding.
There is one practical edge case: receiving USDC on a new network does not necessarily give you that network’s native token for a later transaction. If you plan to use the USDC immediately, check whether you already have destination gas or whether a gas-delivery option is available in the route. After submitting, keep the source transaction record and follow the transfer status until the asset appears on the intended network; a confirmed source transaction alone does not show that the destination transfer has finished.
Use Bungee bridge to compare the asset delivered, the amount received and the steps needed after arrival, then choose the route that fits your transfer.
