First, every operation related with your crypto assets is carried out via well-tested and deployed smart contracts. There is no way for anything (including ButterSwap developer team) to manipulate your assets.
Second, all smart contract source code is available in the GitHub repo. Anyone is welcome to review the source code and compare it with the deployed version on the blockchain.
Third, our smart contract source code has been audited independently by the prestigious security company CertiK and KNOWNSEC. Before our launch, they have helped us tested and improved the security mechanisms. Refer to the Audit page for more details.

⚠️⚠️⚠️ Currently only Heco Chain is supported ❗️❗️❗️

When you open TokenPocket, in the "Assets" section, in the top-left corner you can see the different wallets on different blockchains available, click on the wallet on Heco Chain.

One possible reason is that you don't have enough HT in your wallet to pay for the gas fee required for the approval operations. Make sure your wallet contains some HT in order to proceed.

There is no locking period for any of your assets. You may deposit or withdraw at any time. Everything is controlled automatically by the deployed smart contracts.

No. All you need is a crypto wallet. Currently, we only support wallets on Heco Chain. As long as you connect your wallet with ButterSwap site, no account registration is needed.
