|

Vector Zulu — Payment Mirror Adapter
|
||||
Polls KoreNet portal feeds for new payment events and executes the full
|
||||
payment mirror lifecycle via api.korenet.cloud.
|
||||
|
||||
Full lifecycle per VZ runbook:
|
||||
INCOMING SWIFT MT103/PACS.008
|
||||
→ MINT mirror tokens
|
||||
→ SETTLE T+0
|
||||
→ REDEEM fiat
|
||||
→ BURN-SELL via venue routing
|
||||
→ CLOSE tranche
|
||||
→ ANCHOR to Ethereum (ISO 20022 proof)
|
||||
→ POST confirmation KoreID back to KoreChain
|
||||
|
||||
Dependencies:
|
||||
- vz_mtls_client.py (Bryan's official client)
|
||||
- koreid.py (KoreID generator)
|
||||
- Redis (event deduplication)
|
||||
- Postgres (audit trail)
