Butter Network Review: Is Its Cross-Chain Bridge Safe to Use?

ButterSwap is presented as a one-step cross-chain swap aggregator: you select assets and networks, and the service finds a route to move value between them. The listed networks include Ethereum, Tron, BNB Chain, Base, Arbitrum, Polygon, Optimism, Linea, Mantle, Scroll, Kaia, X Layer, Blast and Merlin. That breadth could be useful if you want to compare routes without handling each bridge separately.

The description does not establish which assets are currently available on each network, which routing providers Butter uses, or whether every listed network is active. A May 2026 report said ButterSwap was paused after an attack involving MAP Protocol and Butter Network. Its current operating status is unknown, so treat the service as unavailable unless Butter confirms it has resumed. Don’t assume that a route shown in an interface is safe or executable just because a network is listed.

Butter Network does not publish a fee schedule. Before any transaction, look for a complete quote that separates the amount you send from the amount expected at the destination. Cross-chain swaps can include network gas, a spread between quoted and market prices, or fees charged by routing providers; those are general costs to check, not confirmed Butter charges.

If the service resumes, compare the quoted output with another route and check whether the quote can change before completion. A low displayed fee is not the whole cost if the destination amount is worse or the transaction can fail. Never approve a wallet transaction if the route, destination network, recipient or final amount is unclear. With no published fees and the service’s status uncertain, there is not enough information to judge Butter’s value against alternatives.

There are important unanswered safety questions. No audit is listed, and Butter Network’s custody model is not clear: you should not assume that funds remain in your wallet throughout a swap or that a transfer can be reversed. The available details also do not establish a licence, insurance, or what safeguards apply if a route fails.

A May 2026 report described ButterSwap as paused while the team coordinated with security partners after an attack involving MAP Protocol and Butter Network. That report is a serious reason for caution, but it does not establish the full scope of the incident or prove the current status of every Butter contract. Treat the service as high risk until Butter confirms a resumption and publishes clear information about affected routes, contract safety and any remediation. Do not send funds based on an old guide or a social post alone.

The general flow for an aggregator is to connect a compatible wallet, choose the source and destination networks and assets, review a route quote, then approve the required transaction. Butter’s one-step positioning suggests it aims to simplify that process, but current wallet support, mobile support, transaction speed and route availability are not published here. A paused service may not let you complete any of those steps safely.

If Butter confirms that it is operating again, use only its verified app entry point, check the network and destination address, and read every wallet prompt. Start with a small amount only after confirming the route is supported and the quote is final. Keep enough native currency on the source network for any transaction gas. Do not share a seed phrase or private key with anyone claiming to help you use Butter.

Butter’s listed network range is broad, but that alone does not tell you whether a specific asset route works or whether liquidity is available when you need it. The project has not published its fees, custody model, current wallet and mobile support, or a listed audit. Its current operating status is also unknown following the reported pause.

Those gaps make it hard to compare the service on cost, recovery options or reliability. If you need a bridge today, choose a service whose operating status, route details and security disclosures you can verify before sending funds. If you are evaluating Butter for later use, wait for a clear resumption announcement and current security information, then check the exact network pair and destination amount before approving anything.
