Wallets and custody

Blockchain address

Also called: Wallet address, Crypto address

A public identifier that can receive coins on a network, derived from a key pair; anyone can send to it, only the key holder can spend from it.

A blockchain address is where coins are sent. It's derived from a public key, so it can be shared freely: knowing an address lets someone pay it, not spend from it. Spending needs the matching private key.

Each network family has its own format:

Ethereum and other EVM networks0x followed by 40 hex characters
Tronstarts with T
Bitcoin (Native SegWit)starts with bc1q

An address on one network is not automatically valid on another. Sending to the right address on the wrong network is the most common way customers lose a payment, which is why the network name belongs next to every address you show.

On Valtu

Each wallet has one EVM address that works on every EVM network Valtu supports, plus its own Tron and Bitcoin addresses. A customer wallet gets all of them in one call. The networks page lists which networks those are today. See also deposit address.
