@iov/bns

This package is an implementation of the BlockchainConnection interface for the BNS blockchain (currently just as bcp-demo prototype). It should be able to adapt this code fairly easily to support any other weave based blockchain as well.

This provides a reference implementation of the full feature set of BlockchainConnection, so it is also a good read when starting support of another blockchain.

Simplest usage, to use auto-detecting tendermint client and standard bns transaction parser:

const connection = await BnsConnection.establish(
  "wss://rpc-private-a-x-exchangenet.iov.one",
);

API Documentation

https://iov-one.github.io/iov-core-docs/latest/iov-bns/

The main entry point is the BnsConnection, which creates a Tendermint client (from iov-tendermint-rpc) and a codec to parse transactions. The BNS codec for reading and writing transactions (also useful for MultiChainSigner) is exported as top-level bnsCodec.
