Balance Sync

The wallet detail page shows a Balance Sync panel that lists every pool address the wallet has ever derived, together with its current on-chain balance. Sync runs on demand — TxNod fetches fresh data from the chain provider for each address. This page covers the two signals operators most often ask about.

Staleness

The Balance Sync panel keeps a per-wallet fresh-TTL of five minutes. Inside that window, the Sync balances button is disabled and the meta line shows Just checked — wait Xm Ys so you don’t fan out provider quota by clicking it repeatedly. After the window elapses, the button re-enables and a click triggers a fresh sync.

Once a sync completes (or while none has run yet), the meta line shows one of:

  • Last synced: <relative time> — the most recent successful sync, with a relative-time label that ages from just now through a minute ago, 5 minutes ago, etc.
  • Last successful sync: <relative time> · showing cached balances — the most recent sync failed; the table is showing the previous successful snapshot.
  • Never synced — the wallet has never been synced; the table is empty until you click Sync.

The five-minute TTL is per-wallet, not per-address; one sync covers every used address in one batch.

Hardware-wallet gap limit

Hardware-wallet companion apps — Ledger Live and Trezor Suite — derive addresses lazily. By default each one only watches index 0 on most chains, even though TxNod’s pool model allocates from index 1 onward. That mismatch produces three different surprise modes depending on the chain family.

EVM (Ethereum, Polygon PoS, BNB Smart Chain)

Ledger Live and Trezor Suite by default show only index 0 on EVM chains. Your derived addresses (indexes 1, 2, 3, and onward) are on-chain and spendable, but invisible in either companion app unless you Add Account per index. TxNod’s Balance Sync is the ground truth.

TRON

Ledger Live TRON typically shows only index 0. Trezor does not support TRON xpub-based wallets at all — TRON wallets in TxNod are Ledger-only on the hardware-wallet side, with manual xpub paste available as a fallback. TxNod’s Balance Sync is the ground truth either way.

Cardano

Ledger Live and Trezor Suite group Cardano addresses under your stake key but may not display every derived payment address. Balance Sync covers every address this wallet has used. (Cardano via Trezor requires Model T or newer; Trezor One is unsupported.)

If a Ledger Live or Trezor Suite balance disagrees with Balance Sync, trust Balance Sync — it queries the chain provider directly for every index the pool has ever allocated, with no client-side gap-limit assumption.
