For Fireblocks’ recommended embedded wallet solution, see Dynamic Embedded Wallets. The documentation below covers the legacy Embedded Wallet APIs and SDKs.
A wallet is an object you manage on Fireblocks’ servers for your end-users. Wallets can have multiple keys (ECDSA and EdDSA) and an unlimited number of wallet accounts. Each wallet account has a single asset type under it. For instance:
  • walletId-1
    • walletAccount-1
      • BTC
      • ETH
    • walletAccount-2
      • FTM
      • TRON
In the new architecture wallet creation is done automatically (if needed) as part of the assignWallet() EW SDK method.

Multiple wallets and wallet accounts

Theoretically, your end-user can have multiple wallets, but that does not matter in the Fireblocks view since Fireblocks does not hold any personally identifiable information (PII) about your end-users. However, for simplicity in our demos, we assume a one-to-one relationship between an end-user and a wallet.
