Technical Deep Dive: Wallet Custody & BSC Connectivity

Wallet Custody & Blockchain Connectivity

Cold storage custody systems, hot wallet transactions, and BNB Smart Chain listener boundaries.

Designed Capability & Architectural Study

System chapter framing

The custody architecture separates wallet operations, hot and cold storage zones, multisig and HSM-style signing paths, and blockchain service interaction.

Connectivity rules

Listeners observe transfer topics and confirmation thresholds before ledger credit. Hostnames, keys, and provider credentials stay off the public surface.

Smart contract interaction boundary

Custody and issuance services interact with chain adapters through controlled signing paths.
