I. Introduction

Money wants to be free, and the Chynge vision of payments is IFS: instant, free, and safe. Payments that are instant and free run on blockchain and crypto. Chynge shall utilize a combination of three items, namely utility tokens, stable coins pegged to global currencies, and the Stellar blockchain to digitize cross-border payments.

Chynge Central, the flagship Chynge solution, utilizes blockchain to track transactions for the delivery of money from the Sender to the Recipient to ensure data integrity and transaction security at high speed and low costs as pricing races towards zero.

The Chynge blockchain is configured as a private, decentralized protocol to preserve customer and data privacy, and to maintain the immutability of the recording of the sub-transactions of a cross-border payment including the last mile delivery for financial inclusion of the unbanked and underbanked customers

As cross-border payments transact on blockchain, there will be less reliance on banking services which shall be a boon to the unbanked and underbanked population.

The Chynge blockchain is based on the Stellar protocol which is optimized for cross-border payments. In addition, the Stellar protocol is the only blockchain that is Shariah compliant as certified by the Shariah Review Board (SRB) of Bahrain. This allows Chynge to differentiate and offer Islamic financial services in Muslim countries.

II. Payments on Blockchain as Envisioned by Chynge

Figure 1: Payments on Blockchain

The steps for cross-border payments on blockchain:

Step 1: Sender sends money to Chynge;

Step 2: Chynge consolidates payments by destination country, buys foreign exchange at wholesale rates from Banks;

Step 3: Chynge sends money via Bank Rails to Bank or Agent Partner in the receiving country; and

Step 4: Chynge or Partner sends money to Recipient and delivers via Bank Account, Mobile Wallet, or Cash Pick-up at Agent.

Each of the four (4) steps as described above shall be written to the Crypto blockchain on the Stellar protocol.

III. Digital Money for Digital Payments

The use of digital money solves the inherent problems in cross-border payments including high costs and slow speed of delivery.

Figure 2: Payments via Blockchain and the Chynge Clearing Center (C³)

The steps for cross-border payments with digital money and blockchain:

Step 1: Sender sends money to Chynge;

Steps 2 and 3: In the Chynge Clearing Center (C³, say c-cube), convert the send currency to stable coin and then re-convert the stable coin to the receiving currency (details follow below);

Step 4: Chynge or Partner sends money to Recipient and delivers via Bank Account, Mobile Wallet, or Cash Pick-up at Agent in support of financial inclusion.

Likewise, each of the four (4) steps as described above shall be written to the Chynge blockchain on the Stellar protocol, and complemented with Chynge utility token CLPX and Chynge Coins pegged to global currencies.

IV. Chynge Clearing Center (C³)

The Chynge Clearing Center (C³) is the fundamental piece in the overall digital payments process. Without C³, payments must remain on traditional bank rails based on traditional currencies that come with the heavy baggage of traditional payments including high service fees, exorbitant foreign currency rates, hidden fees, and slow delivery times.

Figure 3: Exchanging Chynge Coins via the Chynge Token CLPX at

The Chynge Clearing Center (C³) serves as an efficient hub to exchange Chynge Coins. However, the supply and demand for the various Chynge Coins for direct exchanges may not be perfectly matched — for example, there may not be sufficient matches for Singapore Dollar Coins (XSGD) and Indonesian Rupiah Coins (XIDR). The introduction of the Chynge Token (CLPX) as an intermediary medium of exchange smoothens the demands for the exchange of all Chynge Coins.

Thus, all the Chynge Coins, say XSGD convert to CLPX and then the CLPX convert to the recipient Chynge Coins, say XIDR. The Chynge Clearing Center shall reside in, a private company incorporated in Singapore, that serves as a decentralized digital assets exchange dedicated to Chynge digital assets such as Chynge Coins and Chynge Tokens.

Figure 4: Chynge Clearing Center to Support Other Digital Assets

Although the Chynge Clearing Center will exchange Chynge Coins and the Chynge Token CLPX for a start, the Chynge Clearing Center may be easily extended to support all digital assets including Bitcoin, Ethereum, Stellar Lumen, Ripple, alt-coins, security tokens, and others.

The may start with Stellar Lumen as one of the other selected crypto assets, and this serves as a launching pad to exchange to other crypto assets.

The Chynge Token CLPX is a utility token to perform a cross-border payment transaction, and serves as a medium of exchange between two Chynge Coins. The price of a CLPX may fluctuate based on supply-and-demand or market sentiment.

The Chynge Coins are stable coins and by definition, their prices do not fluctuate. Each Chynge Coin shall be pegged to a corresponding global currency and that value shall remain at the unit value of that currency. For example, an XUSD Chynge Coin shall always be priced at USD 1.00.

There may be slight variation in pricing from parity due to liquidity demands for that global currency from the Chynge Coin of that global currency. For instance, when there is a higher demand for the XUSD Chynge Coin, then the price of that XUSD may be slightly higher than USD 1.00.

V. Chynge Coins in a Closed Loop Ecosystem

Figure 5: Chynge Coin Exchanges with Chynge Token CLPX Only

Chynge Coins can exchange only and only with the Chynge Token CLPX. Chynge Coins cannot exchange directly with other Chynge Coins. Chynge Coins cannot exchange directly with other digital assets including but not limited to cryptocurrencies such as Bitcoin and Ethereum, alt-coins, stable coins, and security-backed tokens.

The Chynge Coins only exist in C³ which is a closed loop Chynge ecosystem that allow the Chynge Coins to exchange only with Chynge Token CLPX as an intermediary between two Chynge Coins.

The Chynge Coins are not, and shall not be legal tender.

VI. Financial Services Industry (FSI) Best Practices for Trust, Safety and Security

The main trust issue with Chynge Coins is that the Chynge Community must believe and trust unfailingly that each Chynge Coin is pegged to at least the equivalent value of the underlying global currency. Without such a financial backing and hence, an underlying trust, there may be a run on or other digital assets exchanges where a flood of Chynge Coin holders abruptly exchange their Chynge Coins back to the underlying global currency.

Figure 6: The Creation of Chynge Coins and Their Exchanges with the Chynge Community

To instill trust in the Chynge Community, there shall be three (3) main Stellar wallets for open, transparent and public verification by the Chynge Community:

Issuer Wallet

This Issuer Wallet issues all the Chynge Coins and Chynge Tokens CLPX in the universe. After the Issuer Wallet distributes all the Coins andTokens to the Distribution Wallet, the Issuer Wallet is then locked.

The Issuer Wallet cannot issue any new Chynge Coins or Chynge Tokens CLPX.

Distribution Wallet

This Distribution Wallet receives all the Chynge Coins from the Issuer Wallet. A small portion of the Chynge Coins from the Distribution Wallet is sent to the Transaction Wallet. The Distribution Wallet acts as a storage safe of the Chynge Coins that are not in general circulation.

The Distribution Wallet cannot issue new Chynge Coins or Chynge Tokens CLPX.

Transaction Wallet

The Transactional Wallet directly transacts with the Chynge Community and distributes Chynge Coins to buyers of Chynge Coins, and also receives Chynge Coins when the Chynge Community redeems their Chynge Coins, and returns the Chynge Coins to Chynge.

The Transaction Wallet cannot issue new Chynge Coins or Chynge Tokens CLPX.

Bank Account

Chynge shall dedicate bank accounts to manage the various currencies from the Chynge Community upon the distribution of Chynge Coins to the Chynge Community. These bank accounts shall be segregated from the operational bank accounts of Chynge so that there is no co-mingling of funds from the Chynge Coins and the funds earmarked for the business operations of Chynge.

This prevents non-intentional spending of funds from Chynge Coins on the operational expenses of Chynge.

To ensure that the Chynge Coins are backed by currency, the Chynge Balance Test (CBT) must hold true:

Figure 7: Trusting the Chynge Coin via the Chynge Balance Test (CBT)

The Chynge Community may at any time scan the Issuer Wallet, Distribution Wallet and Transaction Wallet via their respective Stellar addresses, so as to verify the contents of the wallets.

The auditors for Chynge shall audit the Bank Accounts and publish the audited monthly balances of the Bank Accounts for the Chynge Community to view.

Chynge shall publish unaudited daily balances of the Bank Accounts to complement the audited monthly balances.

The trust for the Chynge Coins by the Chynge Community shall be reinforced when the Chynge Community reconciles the balances of the Wallets and the Bank Accounts, and then apply the Chynge Balance Test (CBT) to ensure that the CBT holds true.

The unaudited daily balances and the audited monthly balances of the Bank Accounts shall be published when at least one of the currencies reaches a threshold of the equivalent of USD 5M (United States Dollars Five Million only) or all the currencies reaches a cumulative threshold of the equivalent of USD 20M (United States Dollars Twenty Million only). The audits shall be performed and certified by a public accountant registered in Singapore and that is part of a global network of auditors.

VII. Corporate Governance

In addition to the CBT, the governance of the Chynge Wallets and Bank Accounts are instrumental for the overall trust, accountability and security of the Chynge Coins. The Chynge Wallets shall each be configured for multiple signatures with at least four (4) signatories. The multiple signatories allow redundancy and failover in the event that a signatory is unavailable due to absence, health or death.

When adding or removing signatories to the Chynge Wallets, a minimum of three (3) signatories are required. The exception is the Issuer Wallet which is locked and cannot issue any new Chynge Tokens or Chynge Coins, and cannot transact either directly or indirectly with the Chynge Community.

When moving Chynge Coins from the Distribution Wallet to the Transaction Wallet, a minimum of two (2) signatories are required.

Chynge Coins shall not be moved from the Distribution Wallet to the Issuer Wallet or moved directly from the Distribution Wallet to the wallets of the Chynge Community.

When moving Chynge Coins from the Transaction Wallet to the wallets of the Chynge Community or from the Transaction Wallet to the Distribution Wallet, any one (1) of the signatories shall suffice.

Figure 8: Governance of Chynge Wallets

Similarly, there will be governance in the management of funds in the Bank Accounts that hold funds that reconcile with the Chynge Wallets. This governance includes multiple signatories before debits are made from these Bank Accounts based on tiers of transaction amounts.

As required by Stellar wallets, a trustline is to be established for each Chynge Coin to be held in the holder’s wallet of the Chynge Community.

VIII. Portfolio of Chynge Coins

The portfolio of Chynge Coins shall include the 160 global currencies, three (3) precious metals, and two (2) Islamic coins. The list of the Chynge Coins can be found at

IX. Business Model

The business model of the Chynge Coin is based on a Service Fee that is payable when converting between the Chynge Coin and the underlying global currency. The Service Fee shall vary based on the available liquidity, export controls imposed on the currency by the local regulators or central bank, and overall demand for that currency or corresponding Chynge Coin by the Chynge Community.

The introduction of the Chynge Coins to the existing Chynge Token CLPX and Chynge token economy would upgrade the Chynge payment system from merely being a sum of assets or utility, to include a medium of exchange.

This medium of exchange reflects the best industry practice of a central exchange house such as the Automated Clearing House (ACH), and will increase the liquidity of Chynge transactions, lower the costs, and increase the speed of transactions.

X. Regulatory Compliance

A robust financial security policy shall be in place to support cross-border digital payments that are safe from financial crimes.

Customer due diligence (CDD) that meet, if not exceed the standards of the banking industry shall be performed on customers who conduct money transfer transactions with Chynge with particular attention on money laundering (ML) and terrorism financing (TF).

Figure 9: Customer Due Diligence (CDD) for Accepting Money

Know-Your-Customer (KYC) shall be conducted at various levels such as Simplified CDD, Standard CDD, and Enhanced CDD based on the risk profile of the customer, and shall include screening against the required sanction lists from the United Nations (UN), the United States Department of Treasury, and other jurisdictions.

Recipients of funds shall be subjected to Know-Your-Beneficiary (KYB) including sanction screening.

Sanction countries shall be excluded from Chynge transactions as a Sender and as a Beneficiary. Companies in addition to individuals that appear in sanction lists shall be excluded from Chynge transactions too.

Source of Funds and Use of Funds shall include documentary support from the Customer or the Beneficiary. There are best industry practices in place for the transaction monitoring of funds, and these practices shall be implemented.

Chain analysis, if any, for Source of Crypto and Use of Crypto is easily documented because the blockchain transactions of Chynge digital payments comprising Chynge Coins can only be performed and recorded in the Chynge Clearing Center (C³) closed-loop ecosystem (Section V above).

XI. Know-Your-Crypto

The new variable for compliance in Chynge digital payments is the transaction monitoring of digital assets, in particular ensuring that the Chynge Token CLPX under our custody is not contaminated by cryptos obtained from criminal activity. One safeguard that is frequently used in the industry is “chain analysis”, in which the recent history of any cryptos used to exchange for Chynge Token CLPX are examined to ensure that they did not come from wallets that are blacklisted or connected to known criminals or criminal typologies such as money laundering (ML) and terrorism financing (TF).

As depicted in Figure 5 above, the Chynge Coins are in a closed-loop system and the risks for financial crimes are mitigated in the transaction monitoring of Source-of-Funds.

Figure 10: Customer Due Diligence (CDD) for Delivering Money

However, the Chynge Token CLPX is in an open loop where it is interchangeable with public digital assets such as Bitcoin, Ethereum, Stellar Lumen, Ripple, and others. Thus, the issue of Source-of-Crypto arises when the Chynge Token CLPX is exchanged with these public digital assets and returns to Chynge Token CLPX to be converted to Chynge stable coins.

The determination of Source-of-Crypto is to mitigate the risks that the Chynge Token CLPX and its historical transactions were not connected with known criminals and criminal activity.

The critical piece of Source-of-Crypto is the depth of historical transactions that are determined during chain analysis. The ideal state of depth for chain analysis is up to the point of genesis of the Chynge Token CLPX; however, a more practical and reasonable depth is to be accepted by Chynge, the community, financial institutions, and law enforcement.

Figure 11: Chain Analysis for Source-of-Crypto

In comparison, the depth of historical transactions for Source-of-Funds for fiat money is one. At present, regulated financial institutions are required to carry out reasonable checks that funds received from a customer are not from criminal activities; however, there are no required investigations “up the chain” of the customer’s business partners to ensure that none of them attained their funds via criminal means.

Thus, digital money, stable coins and utility tokens are held to a higher standard of proof when the depth of chain analysis for Source-of-Crypto goes beyond one which is the standard for Source-of-Funds. Currently, there is neither a standard for regulatory compliance nor a standard for industry best practice for Source-of-Crypto. A depth range of four to seven levels makes for a good basis and there may be further refinements as we gather experience in this nascent business process to mitigate money laundering and terrorism financing in Source-of-Crypto.
