Networks and tokens

Block explorer

A website that shows a network's blocks, transactions, addresses and token contracts, the usual way to look up a transaction by its hash.

A block explorer reads a network and presents it in a browser: search a transaction hash to see whether it's confirmed, an address to see its balance and history, or a token contract to check it's the real one. Each network has its own explorers.

Explorers are useful for support ("here's your transaction") and for checking details, such as a token's real contract address. Two cautions:

  • An explorer shows a transaction as soon as it's in a block, before it's final. "Success" on an explorer isn't a reason to credit.
  • Anyone can create a token with any name. Check the contract address, not the name.

On Valtu

Every coin page shows the token's contract address with a link to view it on an explorer. Deposits and payouts carry their transaction hash, so support can link a customer straight to their transaction. For crediting, rely on the deposit.confirmed webhook, not the explorer.
