# Accept Crypto-Assets

The Accept Crypto-Assets section covers how merchants can enable end users to transfer crypto-assets to their Tylt-managed wallets. This section provides guidance on creating transaction requests, supporting multiple cryptocurrencies, and managing the lifecycle of incoming crypto-asset transfers.

#### Key Capabilities

* **Creating Pay-In Requests**\
  Merchants can generate pay-in instances that allow end users to transfer supported crypto-assets. These requests can be configured using either crypto or fiat-denominated base values.
* **Transaction History**\
  Merchants can access a complete history of all incoming transactions for monitoring, reconciliation, and reporting.
* **Transaction Information**\
  Detailed information for a specific transaction can be retrieved using the associated order or transaction identifier.
* **Webhook Integration**\
  Tylt provides webhook-based callbacks to deliver real-time updates on transaction state changes throughout the lifecycle.
