Operational checklist for exchange and custody integrations.

Protocol model, architecture, economics, and implementation notes.

QP chain precision is 8 decimals. The smallest unit is atomic (1 QP = 100,000,000 base units).

/balance returns balance (QP), balance_atoms (raw), and decimals=8.
Wallet UX may still display/send whole-number QP by default for simplicity.
DEX lot engine is whole-token by design (first 5,000 QP lot, then 1,000-QP lots). Fractional lot qty is rejected.
DEX auth signing uses canonical integer qty string: DEX|SIDE|TOKEN|QTY|NONCE|ADDRESS.
