Limitless supports three wallet types: Externally Owned Accounts (EOA), Embedded Wallets, and Smart Wallets. Each type has different characteristics and tradeoffs for users.

​
Externally Owned Account (EOA)

An Externally Owned Account (EOA) is a blockchain account controlled by a user via a private key. The private key is a secret value used to sign transactions. It must be kept secure and never shared. Common EOA wallet interfaces: MetaMask, Rainbow, Coinbase Wallet, Rabby, and similar browser extensions or mobile apps. On Limitless: Users connect an EOA from the main login menu. For every on-chain transaction, the user must approve it in their wallet interface (e.g., MetaMask).

Embedded wallet

An Embedded Wallet is a non-custodial wallet created and operated within an application by a third-party provider, without a separate wallet app. On Limitless: When users sign in via social login (e.g., Google, Twitter), an embedded wallet is created automatically after authentication. Transactions can be executed directly from the app without an extra approval step in an external wallet.

Smart wallet

A Smart Wallet is an account implemented as a smart contract on-chain. It supports features such as:
  • Account recovery
  • Programmable logic for custom behavior
  • Gas fee abstraction and batched transactions
On Limitless: Smart wallets are used primarily to remove the need for users to hold native tokens (e.g., ETH) to pay transaction fees. Users sign in via social login, and a smart wallet instance is created based on their embedded wallet. Transaction fees are sponsored by Limitless, while users only need to hold USDC for trading activity.

Summary

​
Depositing and withdrawing funds

Limitless does not hold a platform balance — your USDC always lives in your wallet on Base. Depositing and withdrawing therefore look different depending on your wallet type.

​
Depositing

  • EOA wallet: bridge or send USDC on Base to your EOA address. Once the balance is on Base, it is immediately usable for trading.
  • Embedded or smart wallet (social login): the Limitless UI shows your embedded and smart wallet addresses. Send USDC on Base to that address to fund the account. You do not need to hold ETH for gas when trading from a smart wallet.

​
Withdrawing

  • EOA wallet: your USDC already sits in your own wallet. To move it elsewhere, send it from your wallet interface (MetaMask, Rabby, etc.) like any other ERC-20 transfer on Base. Limitless does not need to be involved.
  • Embedded or smart wallet (social login): use the Withdraw action inside the Limitless UI to transfer USDC from your smart wallet to another address on Base. Gas is sponsored by the platform.
  • Programmatic partners: server-managed wallets withdraw via the POST /portfolio/withdraw endpoint. The destination address must either be the authenticated account, its smart wallet, or an allowlisted withdrawal address on the profile.
All deposits and withdrawals settle on Base. Sending USDC from another chain (Ethereum mainnet, Arbitrum, etc.) without bridging first will not be credited — bridge to Base before sending.
