Frequently Asked Questions

• How do Daimo accounts work?

  Daimo accounts are Ethereum accounts.

  Under the hood, they're a new and much-improved type called an ERC-4337 contract account. Each device you add to your account stores a secret key. When you send money, your phone first authenticates you with FaceID or similar, then cryptographically signs the transaction using that key.

  Daimo is non-custodial. Your keys, your coins.

  Daimo offers stronger security than traditional wallets. Keys live in dedicated hardware made for storing secrets, such as Secure Enclave on iPhone, and never leave your device.
• Which stablecoin does Daimo use?

  Daimo runs on USDC, a high-quality stablecoin issued by Circle.

  Stablecoins are cryptocurrencies designed to maintain a stable value. Many are pegged to the dollar, so that one coin is worth $1. Circle is a US-based licensed money transmitter partnered with Coinbase. USDC is one of the largest and most liquid onchain dollar equivalents. Learn more on Bluechip.
• Which blockchain does it run on?

  Daimo uses Base, an Ethereum rollup.

  Rollups support near-instant transactions that cost a few cents each. By contrast, transactions on the underlying Ethereum chain (layer 1 or L1) take about 10 times as long and cost a few dollars each. Rollups accomplish this by bundling many transactions into a single L1 transaction. They inherit the strong guarantees of Ethereum: like L1, Base is reliable and secure, and works worldwide.

• Can I send other coins like USDT, or use other chains like Polygon?

  Not yet. We plan to support payments in other stablecoins and on other chains soon.
• Who can see my Daimo transactions?

  Currently, all Ethereum transactions are generally public, including Daimo transactions. We plan to add private payments as the infrastructure and support for them matures.
• Is Daimo open source?

  Yes, Daimo is and will always be open-source under GPLv3. We're here to collaborate. We want to make self-custody fast, safe, and easy. See more on our Github.
