You may have heard "not your keys, not your coins". Self-custody means you are in control of your assets. The alternative, custodial wallets, involves third-party control, leading to risks like hacks, mismanagement, and restrictions that are out of your control.

We believe the future is in better hands if it is in the hands of the people. Ultimately it means lower fees, open road for innovation and ensuring freedom to transact.

If you're still writing down a seed phrase, there's a better way forward.

Most leading self-custody wallets require users to write down their seed phrase and store it securely for fund recovery. We've spoken with many people including lawyers, doctors and engineers—who, despite being perfectly capable of managing this task, often avoid it, hoping nothing goes wrong until it's too late.

Learn more about how we've eliminated seed phrases in our security section.

Doppio uses Safe smart contracts with multiple security layers:

• Your device key is secured by your phone's secure enclave
• 2/2 multisig with Doppio's signer enables transaction limits and remote lock capability
• Encrypted backups to your personal cloud storage
• Optional guardian recovery system

For detailed information about our security model, visit our security page.

Your funds remain secure and accessible even if Doppio ceases operations. Our wallets are built on Safe's battle-tested smart contracts, which have secured over $100B and been in production for 4+ years.

You can access your wallet through any Ethereum wallet that supports Safe smart accounts, and your appointed guardians can help you recover access through Safe's social recovery system. For detailed information about our shutdown protection measures, visit our security page.

Doppio supports both mobile and web. You can log into your account on a web browser to view your account and initiate tractions, but you always need a mobile device to sign transactions. You can link multiple mobile devices where a new key is created and associated with your account.

Alternatively, if you need to recover your wallet you can follow the Recovery Process.

We feel the leading self-custody wallets support too many chains and assets making it difficult and confusing for the every day user.

Our approach for selecting assets to support is rooted in what we would recommend to family and friends. Our goal is to create a wallet that is useful for every day use. Currently, we support two assets: USDC and bridged bitcoin (tBTC) on Base, an L2 on Ethereum.

While we plan to maintain a focused selection of assets, we do plan to allow deposits and withdrawals across chains in the future. The reason for this is that we don't want users to not be able to pay someone in the recipient's preferred chain or asset.

Unlike leading self-custody wallets, we do not focus on NFTs, gaming or speculative memecoin trading. Instead we are focused on features that can be useful for every day user needs with features like payment requests, sending to an email, shared accounts, spending cards, account statements, labeling, etc.
