What is the Amp cryptocurrency & Flexa – How Do They Work?


What is the Amp Cryptocurrency?

AMP is a decentralized cryptocurrency designed to make payments fast, easy, and affordable. It’s based on the Ethereum blockchain and has been developed with the help of leading experts in finance, cryptography, and distributed systems.

How does it work?

Token balances are assigned to hexadecimal numbers using a typical ERC20 token. Total quantity of tokens is represented by the sum of all Ethereum addresses and their respective balances. Ethereum addresses are represented by their respective balances.

The Crypto is similar to a rudimentary token in that balances are given to Ethereum addresses, but the tokens additionally belong to a specific 32-byte partition that essentially acts as a second dimension in the distribution array of the balances.

Given that tokens do not have a reciprocal relationship across partitions (as is true for address parameters), the entire supply of a token is equal to the sum of the balances across all addresses and partitions.

Why Choose Amp?

Amp’s smart contract capabilities, which are specifically designed for collateral, assist you in decentralizing risk for your users. There is nothing more or less to say.

Collateral as a service

Amp collateralization has been tested and audited, and it is accessible for anybody to use without restriction. It’s simple to create applications that lock and unlock Amp on demand in order to safeguard transactions, facilitate lending, and accelerate the movement of money and value.

Extensible and open-source

The currency was created with the goal of being as adaptable and future-proof as possible. Because of Amp’s open-source licensing, it is feasible to develop and distribute bespoke collateral managers for your app, allowing you to communicate with Amp on your terms.


As a consequence of the token’s fixed supply, current implementations benefit from enhanced liquidity and decentralization. As a result of the token’s fixed supply, volatility is reduced and collateral quality is improved.


The token does not make any distinctions depending on the consensus process or the kind of asset. It is possible to employ Amp as collateral to secure transactions of any form, whether they are digital or physical.

Transfers between addresses and partitions

It includes the transferByPartition function, which allows addresses to transfer tokens on the caller’s behalf, but only from a specific partition. It also includes the approveByPartition function, which allows an address to transfer tokens on the caller’s behalf, but only from a specific partition.

It is necessary to retain backwards compatibility with ERC20 in order to perform all ERC20 activities, including transfer and approval, on the zero partition (i.e., the default partition). 

When a transfer is made, two events are sent, which are used to monitor balances off-chain:

• Transfer: This section comprises the to and from addresses, as well as the amount being sent. If the transfer merely changes the partition and not the address, the event will be emitted, but the primary addresses will remain the same as they were before the transfer.

  • Transferbypartition: It includes the same data as Transfer, as well as the to and from partitions, and any metadata or operatorData parameters that may have been included in Transfer.

Token Hooks

A new feature in the token transfer hooks on the blockchain, which make calls at the moment of transfer to external (non-Amp) smart contracts that are set up so that they may be notified about and respond to specific transfer operations.

Each argument in the transfer hook calls includes all of the information associated with the Amp transfer (e.g., from, to, operator, amount, and partitions), as well as any additional metadata.

Thus, it is possible for hook implementations to act/react on individual transfers over their entire breadth and scope. Examples include the data and operatorData arguments that are provided in the transferByPartition method, which are essential to the hook implementations.

If an implementation is available and has registered the supported interface, all transfer and transferByPartition calls will trigger the hooks listed below if the interface is supported.

tokensToTransfer is a function that is invoked on behalf of the token sender (from address). This transfer hook will be invoked if an implementation of AmpTokensSender has been registered by or on behalf of the sender; this hook is often used to gate or stop a transfer.

In any instance, both the sender hook implementation and the receiver hook implementation have the ability to reverse the transaction. The ability to do so exists because ownership of the tokens is not retrospectively erased (i.e., a sender may stop their own transfer, or a recipient can prohibit the receiving of Amp from a third party, but not the other way around).

When it comes to regular account transfers, token transfer hooks are not necessary. However, they are crucial for smart contract collateral managers, who rely on them to respond to new collateral and execute scope-specific functionality (e.g., withdrawal, authorization and processing rewards).

What Is Flexa?

Flexa is a new payment system that uses blockchain technology to create a secure digital currency called AMP (short for “Advance Money Payment”). It allows people to buy goods and services online using AMP instead of traditional credit cards.

In order to enable compliant settlement across a wide range of countries, the network involves a number of exchanges and financial institutions.

When used in conjunction with current point of sale (POS) systems and online platforms, Flexa makes it possible to accept payments during the regular checkout process. 

It is possible to produce unique, interoperable authorization codes for conveyance by using the network Spend SDK, which is permissionless. Mobile wallets or apps may create these authorisation codes.

Decentralized collateral is a fundamental component of Flexa’s architecture since it allows it to absolutely and instantaneously guarantee all merchant payments without relying on other protocols or network participants. It is possible to remove the majority of the expenses associated with the issues of money verification and payment fraud by demanding that each transaction be completely collateralized.

How does flexa work?

Flexa uses the AMP cryptocurrency to power its payment system. This means that when you use Flexa to buy something online, you’re actually using AMP as currency. You’ll see the AMP symbol next to the purchase button.

Because of this, the whole network transaction income is used to support the continual open-market purchase of Amp tokens, which are then redistributed as network rewards as an incentive for giving collateral.

As a result, Flexa effectively decentralizes transaction insurance by detaching merchant settlement from the original consumer payment, allowing it to deliver rapid finality as a service to its customers.


When a mobile wallet application wants to connect to the open network, it creates a unique partition within its own strategy and collateral manager.

This partition is where application-specific rewards are deposited (in the case of a successful settlement) and where consumed collateral is transferred (in the case of a failed settlement). For the collateral manager, these pools are represented as sub-partitions inside the partition scope of the partition.

The transferByPartition function is used by Amp token holders to place collateral on a specific application on the Flexa network. To do so, they transfer tokens to the partition corresponding to the selected application using the transferByPartition function.

Valid partitions must be registered inside the collateral manager, and transfers to partitions that are not on the allowlist are prevented by the transfer validation hook from the Amp contract. Valid partitions must be registered within the collateral manager. There are no further constraints on Amp token holders who want to provide tokens to the Flexa collateral manager.

More extensibility

In order to take into account current network restrictions, the Amp token smart contract has been constructed in such a way that it is compatible with scaling advancements like as zero-knowledge proof (ZKP) systems, optimistic rollups, and Ethereum 2.

It is anticipated that collateral managers will have access to safe micro-collateralization transactions on the blockchain as the system grows in size. Additionally, future reward distributions may be performed via verifiable and trustless ZKPs, which will lower transaction costs while while maintaining network data privacy.

Token partitions may also facilitate the creation of new sorts of collateral assets that can be used across many platforms at the same time.

In addition, collateral managers may manufacture bearer tokens based on any staked collateral; for example, enabling non-custodial transfers of proxy yield tokens produced from Amp, which are currently unavailable.

This concept is also applicable to DLT-based networks, where it may be used to assist cross-chain token minting in order to promote quick collateral deployment.

The Tokenomics Of AMP

It is intended to be a low-volatility collateral token whose value increases consistently as a direct consequence of the usefulness it provides to the community.

A trend toward open token networks, in which users generate and extract all inherent platform value via endogenous economic incentives, is reflected in this development. Due to the fact that the crypto is supported solely by its literal usage and not by any extrinsic assets, it is vital to model the economic underpinning of the company.

As a result, this company strategy is both more cost effective and more productive than previous business models. It employs simple and transparent financial primitives (e.g., fixed supply, rudimentary staking mechanics) and avoids complicated synthetic or derivative instruments, rebasing mechanisms, multi-asset algorithmic models, and artificial constraints that are overly complex to users.

Amp is designed to be a low-cost, low-risk alternative to traditional financial instruments. To achieve tenfold more usefulness,instead the proect focuses on offering high-quality collateral, stability, and self-sustaining features.

Collateral for the Flexa network When it comes to securing retail payments inside the Flexa network, Amp is the key collateral token.

Wallets and apps are staked with Amp in order to provide spending capacity to users. Merchants are charged a tiny percentage-based fee for every successful transaction (for comparison, less than the prevailing interchange rate). It is the sole fee associated with Flexa’s finality-as-a-service and fraud-elimination services, and it is paid in advance.

Afterwards, the funds are used to acquire Amp tokens on the open market, which will be distributed autonomously to collateral contracts. These non-inflationary network incentives are distributed directly to network members in proportion to the amount of Amp they have staked.

Increased payment utility (spending throughput), increased collateral requirements, and compounding incentives are all part of a self-reinforcing cycle that will guarantee that all Flexa network value is captured in tokens.

Amp is the first initiative to allow participants to place collateral while still preserving possession of the underlying assets, according to the project’s developers.

Users’ interactions with the Flexa network are greatly simplified as a result of this new implementation of partition schemes and modular collateral managers, which facilitates broad adoption and decentralization of the Flexa network. In exchange for staking Amp in order to enable ubiquitous, permissionless spending utility, participants may receive the totality of the network’s revenues.

For novel token networks to be successful, they must be able to challenge and bypass the present system in a positive manner. In order to assess the link between payment utility and predicted aggregate network value, a variety of models are investigated.

Although the Amp cryptoeconomic model is clear, the predictions of associated token value (i.e., the utility of the collateral itself) include understanding system dynamics such as platform development, staking composition, and velocity/stability rates, among others.

The value of Amp collateral is determined by combining current models for economic development, capital asset price, continuous market buy-pressure, and discounted cash flow to determine the value of the collateral.
