Frequently Asked Questions

How does a wallet read balances through the API?

The wallet calls a supported endpoint for the required network and address. Settla returns blockchain data from the connected node or API layer.

Can the API broadcast signed transactions?

Yes, supported networks can accept already signed transactions. Private keys should remain inside the wallet or protected signer.

Do wallets need a separate node for every chain?

Not necessarily. A multi-network API layer lets a wallet connect several chains without operating each node directly.

Is it suitable for custodial and non-custodial wallets?

Yes, but signing and custody architecture stay on the product side. Settla provides the infrastructure access layer.
