Recording Crypto Transactions from the Transaction Hash

Crypto is the one form in Nexto where you do not type the amount. You paste the transaction hash, and Nexto reads the amount, the sender and the receiver straight from the blockchain. This episode covers the one-time setup, the transaction form itself, and the two guards that stop wrong or duplicate records.

What you will learn

• How to define a wallet as an account with its network and address
• What the token contract registry is and when you need to touch it
• How pasting a transaction hash fills in the whole form
• Why a crypto transfer lands in the same ledger as everything else
• How to rent energy on the Tron network before you send
• The two guards — duplicate hash and unknown receiving address

Step by step

Define your wallet as an account

Before the first transaction, two things need to be set up, and you do both once.

The wallet is an account like any other — the rule from core concepts still holds. You set its type to wallet, choose the network, and paste the wallet address. From then on, any transaction landing at that address is recognised as belonging to this account.

Check the contract registry

Every token on a network has its own contract address — that is its identity card. The well-known ones are already there, so in practice you rarely touch this page.

If you work with a token that is not listed, you add it: the network, the contract address, the symbol and the number of decimals.

Paste the transaction hash

Now the transaction form itself, and it is remarkably empty — because almost everything on it gets filled in for you. The only box that matters is the transaction hash.

A customer sends us USDT and sends the hash along with it. Paste it in, and Nexto goes to the chain by itself and brings back the transaction: the amount, the token, the sending address, the receiving address, and how many confirmations it has. Nothing there was typed by us; this is what the blockchain says, and it cannot be argued with.

Add the human part

All that is left is which customer this belongs to. The chain knows the address, but it does not know whose customer that address is. Pick the account, write a description, and record.

Check the resulting document

The result is an ordinary transfer document — the customer account on one side, the wallet on the other, with the hash sitting in the tracking code field. A crypto transaction is not some separate world; it lands in the same ledger as everything else.

Read the wallet ledger

The wallet ledger shows the effect: the balance went up by exactly that amount. This page is your answer to "how much do we hold on-chain right now", and it is built from documents, not from a note somebody kept.

Rent energy before you send on Tron

There is a practical extra on this page. On the Tron network, sending a token costs energy — and if your wallet has none, the fee comes out in coin and it is not cheap. Nexto lets you rent energy for the address before you send. On a busy day that alone pays for itself.

Tips

• Take a token's contract address from the token's official source, never from a message somebody forwarded you.
• A hash that has already been recorded will not be accepted a second time, so the same transaction cannot be booked twice by mistake.
• If the receiving address does not match any wallet you have defined, Nexto tells you rather than quietly filing it somewhere wrong.
• The in-app page help (the ? icon at the top of the page) has more detail.

FAQ

Do I ever type the amount on a crypto transaction?

No. You paste the transaction hash and Nexto fetches the amount, the token, the sending and receiving addresses and the confirmation count from the chain. The only thing you supply is which customer the transaction belongs to, plus a description.

What happens if someone pastes the same hash twice?

Nexto refuses it. A hash that has already been recorded will not be accepted a second time, which means the same transfer cannot be booked twice by mistake.

Why does Nexto need my wallet defined as an account?

So it can tell that a transaction belongs to you. Once the wallet address is stored on the account, anything landing at that address is recognised. If a hash points at a receiving address you have not defined, Nexto warns you instead of filing it somewhere wrong.

Why would I rent energy on the Tron network?

Because sending a token on Tron costs energy, and a wallet with no energy pays the fee in coin instead — which is not cheap. Renting energy for the address before you send is cheaper, and on a busy day it pays for itself.
