Functions

func CheckTendermintError added in v0.40.0 

func CheckTendermintError(err error, txBytes []byte) *sdk.TxResponse

CheckTendermintError checks if the error returned from BroadcastTx is a Tendermint error that is returned before the tx is submitted due to precondition checks that failed. If an Tendermint error is detected, this function returns the correct code back in TxResponse.

TODO: Avoid brittle string matching in favor of error matching. This requires a change to Tendermint's RPCError type to allow retrieval or matching against a concrete error type.

func GetFromFields added in v0.36.0 

func GetFromFields(kr keyring.Keyring, from string, genOnly bool) (sdk.AccAddress, string, keyring.KeyType, error)

func NewClientFromNode added in v0.42.5 

func NewClientFromNode(nodeURI string) (*rpchttp.HTTP, error)

NewClientFromNode sets up Client implementation that communicates with a Tendermint node over JSON RPC and WebSockets TODO: We might not need to manually append `/websocket`: https://github.com/cosmos/cosmos-sdk/issues/8986

Paginate returns the correct starting and ending index for a paginated query, given that client provides a desired page and limit of objects and the handler provides the total number of objects. The start page is assumed to be 1-indexed.
