Transactions & Queries

A Transaction is any action that changes the state of the Cudos blockchain.

Each computational operation that creates, stores or updates data is a transaction and incurs a gas fee.

Transactions include:

  • messages
  • fees
  • signature from a key

A transaction can be initiated with a wallet or cudos-noded CLI. It must be signed by the creator of the transaction.

The transaction is added to a block by a Validator and broadcast.

Execute transaction

Use cudos-noded CLI to send tokens from one account to another:

Insert the relevant addresses and chain_id.

info

You may want to cap the maximum gas that can be consumed by the transaction via the --gas flag. If you pass --gas=auto, the gas supply will be automatically estimated before executing the transaction

Example execute transaction

cudos-noded tx bank send <sender_key_name_or_address> <recipient_address> 10acudos \
--chain-id=<chain_id> --gas=auto

Query transaction

A Query is a transaction that does not change the state of the blockchain as it simply reads data without changing it.

The following transaction queries are available on cudos-noded CLI

commanddescription
txQuery for a transaction by hash, "addr/seq" combination or comma-separated signatures in a committed block
txsQuery for paginated transactions that match a set of events
upgradeQuerying commands for the upgrade module
wasmQuerying commands for the wasm module
Flags:
--height int Use a specific height to query state at (this can error if the node is pruning state)
-h, --help help for tx
--node string <host>:<port> to Tendermint RPC interface for this chain (default "tcp://localhost:26657")
-o, --output string Output format (text|json) (default "text")
--type string The type to be used when querying tx, can be one of "hash", "acc_seq", "signature" (default "hash")

Global Flags:
--chain-id string The network chain ID
--home string directory for config and data (default "/Users/adiamond/projects/run-node/cudos-node/cudos-data")
--log_format string The logging format (json|plain) (default "plain")
--log_level string The logging level (trace|debug|info|warn|error|fatal|panic) (default "info")
--trace print out full stack trace on errors

Transaction queries must be in the following format:

cudos-noded query tx --type=[hash|acc_seq|signature][hash|acc_seq|signature] [flags]

Example query transaction

In the example below, the following data has been used:

type = hash hash = 2CC4F15A23122F209B9209EAD1D7C37B84ADF5E37BE78234386FBDBB8AD3C788 flag = --node http://sentry1.gcp-uscentral1.cudos.org:26657

cudos-noded query tx --type=hash 2CC4F15A23122F209B9209EAD1D7C37B84ADF5E37BE78234386FBDBB8AD3C788 --node http://sentry1.gcp-uscentral1.cudos.org:26657
