| Mint | Creation of a stablecoin within the BPN ecosystem. |
| Burn | Redemption and removal of stablecoins from circulation. |
| Swap | Conversion between two stablecoins using BPN’s liquidity pools. |
| Route | Pathway a payment takes across different liquidity pools or corridors. |
| Settlement Guarantee | Protocol-level assurance that cross-layer transactions finalize atomically. |
| Programmable Compliance | On-chain rules enforcing KYC/AML and jurisdictional restrictions at the protocol level. |
| Regulated Reserve Custody | Fiat reserves held in licensed financial institutions, with periodic attestations. |
| Permissionless Access | Unrestricted participation in the open protocol layer, subject to compliance screening. |
