What is the best way to handle UTxOs when integrating Cardano wallets?▼

The best way to handle UTxOs when integrating Cardano wallets is by using Mesh formats through MeshSDK. This approach streamlines address retrieval, UTxO access, and transaction signing across both browser and headless wallet environments.

Can I use MeshWallet to return full transaction data when signing?▼

Yes, you can use MeshWallet to return full transaction data when signing. It meets CIP-30 compatibility requirements including signTx and ReturnFullTx, alongside bech32 address handling and CIP-8 data signing.
