Security record

Backpack has not been reviewed for the site's security record yet. The record counts only the maker's own failures — a firmware or app bug, a poisoned update, a breached vendor, weak key generation — and is kept in the wallet hacks review.

Questions

Which coins does Backpack support?

Solana and Ethereum, plus tokens on Solana, Ethereum and Sui.

Is Backpack open source?

Yes. Its source code is public at https://github.com/coral-xyz/backpack.

Does Backpack support multisig?

Not as far as the directory records. A multi-signature setup needs a wallet that can hold one of several keys; see the wallets directory for the ones that do.

Is Backpack custodial?

No. Backpack is self-custody: the user holds the keys, and nobody else can move the funds.
