About Hub20

In one sentence: Hub20 is an open source, self-hosted payment processor for Ethereum and EVM-compatible networks.

It works as a web application that can interact with network that is compatible with Ethereum’s JSON RPC API. It can keep track of any type of token transfer between two different parties. It hides all of the complexity from end-users so that they can make and receive payments in the blockchains native currency or ERC20-compliant token. It abstracts away all the details and provides the fastest/cheapest possible route to make it easy for people to accept cryptocurrencies as payment online.

In practice, one can think of each instance of Hub20 of a single “crypto bank” where users simply have access to their individual accounts and token balances, while the person running the deployment (hub operator or hub owner) is the one with actual access to the bank vault and funds.


For users who just want a simple way to make cheap/fast transfers with crypto:

  • Direct, peer-to-peer payments for any Ethereum-compatible token.
  • No transaction fees for transfers between accounts of the same instance
  • Payments are always sent using the cheapest route possible

For merchants:

  • No transaction fees for accepting payments
  • No KYC
  • Easy to integrate checkout widget on third party sites, lets you accept crypto payments via blockchain or “layer-2” networks - such as Raiden

For developers:

  • Pluggable architecture for managing Ethereum accounts: you can use standard keystore accounts, HD Wallets or implement your own method.
  • Easy to extend and add modules - e.g, hub operators can aggregate user deposits and add liquidity to Decentralized Exchanges and possibly earning money for everyone

Beyond payment processing

Hub20 can be used by individuals and businesses of any size and manage any amount of funds. Its focus however stays on providing easy to use functionality for small groups and communities whose peers know each other and already have established trust among themselves.
