Notifications on withdrawals and deposits for selected address

[anujmax]

As I understand, EthConnect is a bridge into Ethereum permissioned chains. Is it possible to register set of address in the permissioned chains to get notification for: withdrawal from and deposit to these address?

Hi @anujmax ,

EthConnect is the raw connector for Ethereum chains (see #149 for where the community is up to on chains with less predictable behaviors than BFT chains with predictable finality).

As a quick incomplete summary it provides:

• Nonce management and reliable transaction submission
• Full ABI<->JSON management for paylods, with simple APIs
• Swagger API generation - note this is moving architecturally up to the FireFly Core layer
• Reliable event streams to register subscriptions for events
  • I think this is what you're asking about

It does not understand the concept of a "Token" natively, as that's a higher level concept. But you can absolutely teach it about any ABI of a contract that happens to use tokens.

FireFly Core on the other hand, does fully understand those concepts. So if you're looking for pre-built support for caching of historical transfers on tokens (vs. just the raw events), it's worth looking there: https://hyperledger.github.io/firefly/gettingstarted/mint_tokens.html
