Balances & Traffic

Two read-only tabs covering the validator's economic position on the network: Canton Coin holdings and synchronizer traffic counters.

Both tabs are read-only in 2.0. There is no top-up, purchase, mint, or transfer action in the UI in this release. Traffic purchases and Canton Coin transfers are performed through the Wallet UI or the Canton console.

Balances

Canton Coin holdings, read from the network's Scan service.

Metric cards

Card	Meaning
Total holdings	The validator's total Canton Coin balance
Unlocked	The portion available to spend
Locked	The portion locked in contracts. Amber when above zero

Snapshot

Row	Meaning
Owner party	The party the balance belongs to.
Available coin	Spendable amount at the time of the snapshot.
Record time	Ledger time the snapshot was taken.
Migration ID	The Canton migration this balance is recorded against.
Computed as of round	The mining round the figures were computed for.

Holding Fees

Total, Unlocked, and Locked holding fees — the ongoing cost of holding Canton Coin.

All amounts are formatted to exactly two decimal places, with thousands separators. A missing value shows as —.

Traffic

Synchronizer traffic counters, read from the participant.

Canton meters the data a participant sends through the synchronizer. Each participant gets a base allowance that refills over time, and can purchase extra traffic beyond it. This tab shows where the validator stands against both.

Metric cards

All three are byte-formatted (B, KB, MB, GB).

Card	Meaning
Extra consumed	Purchased traffic consumed so far
Extra limit	Total purchased traffic allowance
Base remaining	Remaining base allowance

When Base remaining is near zero and Extra consumed is approaching Extra limit, the participant is close to being throttled by the synchronizer, and command submission will start failing. Purchase additional traffic through the Wallet UI before that happens.

Routing

Domain ID, Participant ID, and Endpoint, each with a copy button. Shown when the synchronizer reports them.

Counters

Last consumed cost, plus any additional counters the synchronizer returns, with humanised labels. The set of counters depends on the Canton protocol version, so this section is deliberately open-ended.
