Our Wallet Custody Offering

Our wallet infrastructure is an API-first solution that enables you to programmatically create and manage segregated Stablecoin vaults. These vaults can be used for a variety of purposes, including providing individual wallets to end-users (e.g., merchants), managing corporate treasury, or facilitating payment flows.

Features

• Create wallets - Enable the issuance of wallets for your business and treasury needs
• Create subwallets - Create subwallets for your sub accounts or end-users for a wide range of applications
• Send/Receive Funds - Move funds from your wallets and subwallets without worrying about the blockchain complexities
• Query wallet balances - Track asset holdings across your wallets and subwallets

Features

Here are some features you can build with our wallet solution.

Wallet terms and definitions

Vaults

Vaults are the primary organizational containers for managing digital assets.

They serve as:

• Segregated wallets that hold multiple blockchain accounts and assets
• Organizational units that can represent different business functions or use cases such as treasury management, and end customer deposit addresses assignment

Account-Based Tokens

Account-based tokens exist on blockchains that use an account model for tracking balances (similar to traditional bank accounts).

Characteristics:

• Single persistent address per asset within a vault
• Balance is maintained as a state variable on the blockchain
• Transactions modify the account balance directly
• Nonce-based transaction ordering

Examples:

• Ethereum (ETH) and all ERC-20 tokens
• Stellar, EOS, Tron

Key behavior: You use the same address repeatedly for receiving funds.

UTXO-Based Tokens

UTXO (Unspent Transaction Output) based tokens exist on blockchains that track individual "coins" or transaction outputs rather than account balances.

Characteristics:

• Multiple addresses can be generated for receiving funds
• Transactions consume specific UTXOs (inputs) and create new UTXOs (outputs)
• No account balance concept—wallet balance is the sum of all unspent outputs
• Enhanced privacy through address rotation

Examples:

• Bitcoin (BTC)
• Litecoin (LTC)

Key behavior: Each transaction can use a new receiving address for improved privacy and tracking.

Memo-Based Assets

Memo-based assets (also called destination tag assets) use a shared address model where a single blockchain address is combined with a unique identifier (tag/memo) to route funds to specific recipients.

Characteristics:

• One address per asset within a vault, shared across all deposits
• Unique tag/memo required for each deposit to identify the recipient
• Tag is included in transaction metadata, not the address itself
• Commonly used by exchanges and custodians for operational efficiency

Examples:

• XRP (Ripple) - uses destination tags
• Stellar (XLM) - uses memo fields

Key behavior: When sending to a tag-based address, both the address AND the tag must be specified, or funds may be lost or misallocated (especially when sending to exchanges / custodians).

Best Practices

• For account based-tokens, assign all addresses in a vault to the same customer.
• Customer deposit management: Sweep customer deposit into a separate collection vault for easier management.
• For memo-based and UTXO tokens, create a single vault and generate unique deposit addresses for each of your customer from the main vault
