What's inside iBnk

  1. Overview of the iBnk DEX Protocol

    iBnk is a decentralized exchange (DEX) protocol designed for the secure and efficient trading of digital assets. It provides a high-performance order matching system supporting limit and market orders, real-time order book updates, and efficient trade settlement. The protocol is designed for multi-chain support, allowing users to trade assets across different blockchain networks and access liquidity from various networks.

  2. Overview of iBnk Stablecoin FX Layer

    iBnk provides a composable, auditable, and low-cost FX Layer for fiat-backed stablecoins accessible through a single API. It abstracts the complexities of blockchain infrastructure—such as chains, bridges, nodes, and market plumbing—allowing enterprises to perform secure, millisecond-level executable FX operations across multiple regulated stablecoins and fiat frameworks without needing to manage the underlying technical friction.

  3. Overview of GBPT Stablecoin

    GBPT is a regulated GBP stablecoin issued by Poundtoken. It is designed for stability and is 100% backed by GBP held in GBP-denominated bank accounts, ensuring it is always redeemable 1:1 for pounds sterling. To maintain transparency and value stability, Poundtoken undergoes monthly audits by KPMG, and monthly assurance reports are provided to holders.

  4. Overview of iBnk Convert API transaction flow

    The iBnk Convert API operates on the Base Sepolia network (chainId: 84532) with a base URL of https://api.ibnk.xyz. The secure transaction flow consists of five stages: 1. Preview (get rates), 2. Approve (authorize Router contract), 3. Build (API constructs unsigned transaction), 4. Sign (client signs locally), and 5. Broadcast (API executes and returns results).

  5. Overview of CADC Stablecoin

    CADC is a stablecoin issued by PAYTRIE AB Inc., a FINTRAC regulated Money Services Business. It is backed by fully reserved assets and is redeemable on a 1:1 basis for Canadian dollars. PayTrie facilitates fiat-to-stablecoin conversion via Interac e-Transfers and provides non-intrusive KYC options.

  6. Overview of iBnk FX Infrastructure

  8. Overview of iBnk Stablecoin FX Infrastructure

    iBnk is a composable, non-custodial FX infrastructure layer for fiat-backed stablecoins. It is not a trading platform, marketplace, custodian, or FX dealer; instead, it provides a technical layer (single API) that allows developers and organizations to access cross-currency stablecoin routes and vetted liquidity sources. It is designed for building digital treasury, payments, and settlement applications without the need to integrate multiple separate partners.

  9. Understand iBnk's non-custodial architecture and role

    iBnk operates as a Composable Stablecoin FX Layer and a technology provider, not a financial service provider. Key architectural constraints include:

    • Non-Custodial Settlement: iBnk never receives, holds, or transfers assets. Settlement occurs directly between the VSE wallet, enterprise user wallet, and stablecoin issuer mint/redeem mechanisms. iBnk only generates settlement instructions.
    • No Price Setting: iBnk does not conduct FX trades or set prices. It computes and validates executable paths using compliant on-chain oracles, regulated price references, and verifiable mint/redeem rules.
    • Technology-Only Fees: iBnk charges for computation, routing, orchestration, monitoring, and audit logs. It does not charge based on FX volume, spreads, or remittance fees.

  10. Understand AUDM payment token fundamentals

    AUDM is a programmable and reliable payment token backed by Australian Dollars held in trust. It maintains a 1:1 peg, meaning one AUDM can be redeemed for one Australian Dollar.

  11. iBnk Protocol API Overview

    The iBnk Protocol API (v2.1.0) provides an interface for stablecoin conversions on supported blockchain networks. The base URL for the API is https://api.ibnk.xyz.
