Bank and payment registry - NodeAsset

An order paid on the ledger is paid in a payment asset: cash on the DA Registry, such as a bank’s tokenized deposit or a stablecoin. Its issuer, , keeps the asset’s registry: for a tokenized deposit, the bank. It can be the venue’s own bank, another bank, or none: an order paid by bank transfer needs no payment registry (Deployment patterns).

What it runs

What	Where
Its party	On its own Canton node, as the payment asset’s registrar
Its registry	On the DA Registry: the payment asset, with its own mints and burns
The packages its node vets	DA’s Registry packages only, and nothing of NodeAsset’s. No NodeAsset contract is disclosed to it

What it signs

Act	When	On the ledger
Mint the payment asset	When an investor’s custodian asks, such as on a deposit	Accepts the custodian’s mint request on its registry (`MintRequest_Accept`)
Burn it	On a withdrawal	Accepts the custodian’s burn request (`BurnRequest_Accept`)
Its leg of each settlement	Each order paid in its asset	Nothing new: the investor’s allocation and the payment move on its registry, in the same transaction as the fund’s units

The payment asset and its number of decimals are terms of the fund’s standing consent, which the fund’s register keeper and treasury sign; the bank does not. Payments land in, and payouts leave, the fund treasury’s own account, in the payment asset only. Who signs each transaction is on The on-ledger payment leg.

What it sees

Its own registry’s batch of each settlement: the payment asset’s holdings and allocations. Nothing of the fund: its register, its orders or its units. The venue is the Registry’s provider for the payment asset too, so it sees the bank’s whole book on that registry, and it issues the payment asset’s admissions (Who sees what).

Its records at the venue

Its mints and burns are its own books. Where the venue configures a register statement for the payment asset, reconciliation compares it with the holdings on the ledger. A bank statement, such as an ISO 20022 camt.053, is kept as received and not compared.

Internal or external

	Internal: the venue’s own bank	External: another bank
Who issues	The bank’s issuance desk, with its own key, apart from the venue desk	The other bank, on its own node
What it signs	The same acts	The same acts
