Building the foundation for payments at planetary scale

#### Fork-free Evolution

Seamless upgrades without disruption

#### Developer First

Robust Infrastructure and tools. Built by developers, for developers

\> npm install ecash-lib

#### Enhanced Security

Trustless security guarantees for instant transaction finality and reorg protection

### Avalanche-Enhanced

Avalanche/Nakamoto hybrid achieves real-time consensus. A historic first for PoW blockchains. Here’s what it unlocks:

#### Instant Finality

Pre-consensus makes transactions irreversible before they are included in a block, reducing settlement time on eCash from 10 minutes to 3 seconds – more than 1000 times faster than Proof of Work-only cryptos like Bitcoin, which take about an hour for strong finality.

#### 51% Attack Protection

Networks with low hash rates are vulnerable to mining attacks. With Avalanche, eCash is protected. An attacker would need not only most of the hash rate, but also most of the staked eCash. Avalanche consensus selects the chain miners will mine on, and the nodes that make up the network are weighted by their stake.

#### 1-block Finality

Post-consensus makes each new block irreversible by locking it in as the valid chain tip. Once a block is finalized it cannot be removed from the chain. This also lays the foundation for Instant Finality, which applies the same principle directly to individual transactions.

#### Staking Rewards

Staking Rewards strengthen the network by incentivizing honest nodes. Each additional coin staked makes the network more invulnerable to attacks. Staking Rewards also fuels eCash’s economic engine, allowing XEC holders to earn passive income, incentivizing holding, and supporting the price by reducing available supply.

#### Consistent Block Times

Minority networks suffer from erratic block times due to abrupt hash switching. Avalanche makes it possible to enforce a much more steady stream of blocks by penalizing blocks that come in too early. Regular block times are also useful for legacy businesses that opt to continue relying on blocks in their business logic.

#### Real-time Transaction Processing

Since the network will not have to wait for a block to validate transactions, transaction throughput increases. Real-time Transaction Processing allows eCash nodes to prepare for each block before confirmation, significantly reducing the amount of work required when a block comes in.

#### Dynamic Block Size

The maximum block size can be decided by Avalanche consensus to allow the network to scale gradually based on the number of transactions. The eCash network will be able to scale with market demand while mitigating spam attacks, and keeping the bandwidth under control.

#### Dynamic Transaction Fees

eCash fees can be adjusted dynamically depending on demand, making it possible to send transactions with very minimal or even no fee at all.

#### Subnets

Subnet validation enables unlimited second layer protocols with virtually no impact on the main chain. Privacy, smart contracts, and other popular features proven out by other chains would be supported on eCash.

#### Fork-Free Upgrades

The introduction of Avalanche consensus on eCash allows network upgrades to take place quickly and behind the scenes without disrupting users or builders. Avalanche is able to take responsibility for network policy rules, rather than being hard-coded and requiring node operators to upgrade before the changes go live.

### Got questions?

## Frequently asked questions

Excited about eCash? So are we! Here are some answers to the most frequently asked eCash questions.

#### What is eCash?

eCash is a cryptocurrency that's designed to be used as electronic cash. Just like the invention of emails made it possible to send direct messages online, eCash makes it possible to send money directly to other people online. This includes being able to use eCash to pay for goods and services.

#### How do I get eCash?

Since eCash transactions go directly between you and whoever you're paying or getting paid by, you don't need a bank account to own it. Instead, you just need an electronic wallet. Once you have a wallet, you can get eCash by buying it on a cryptocurrency exchange and then sending it to your wallet. Other people can also send eCash to your wallet.

#### What can I use eCash for?

You can use eCash to send and receive payments without the need for a bank account. It's available in every country, and you can use it to send and receive cross-border payments anywhere in the world.

#### Where can I find eCash price information compared to other cryptocurrencies?

eCash price information is available at all leading crypto research sources, like Coingecko, Coinmarketcap, and Crypto.com.

#### What is the supply of eCash?

eCash has the same fixed supply as bitcoin. The default base unit of eCash has 2 decimal places (100 satoshis). The default base unit of bitcoin (BTC) has 8 decimal places (100,000,000 satoshis). 90% of all the eCash that will ever exist has already been mined. The inflation rate for eCash is already low (less than 1% as of 2025), and will decrease to zero.
