  bitcoin: v0.0.2
  bitcoin-wallet: set state as default case for handle-provider-update
  %bitcoin: Implement additional RPC calls from btc-provider. %histogram, %block-headers, %tx-from-pos, %fee, %psbt are now all callable from the btc-provider agent. These actions are necessary in order to get the lightning network working within Urbit.
  %bitcoin: Added %regtest to arms using the network type definition.
  %bitcoin: add regtest type to network
