Execute Flow Interaction Templates (FLIX) with the Flow CLI

The Flow CLI provides a command to execute Flow Interaction Templates (FLIX). FLIX are an easy way to interact with Flow. They are a standard for distributing Cadence scripts and transactions, and metadata about them, in a way that is consumable by tooling and wallets. FLIX are audited for correctness and safety by an ecosystem of auditors.


_10
flow flix <query> [<argument> <argument>...] [flags]

Queries can be a FLIX id, name, or path to a local FLIX file.

Example Usage​


_10
# Execute a FLIX transaction by name on Testnet
_10
flow flix transfer-flow 5.0 "0x123" --network testnet --signer "testnet-account"


_10
# Execute a FLIX script by id on Testnet
_10
flow flix bd10ab0bf472e6b58ecc0398e9b3d1bd58a4205f14a7099c52c0640d9589295f --network testnet


_10
# Execute a local FLIX script by path on Testnet
_10
flow flix ./multiply.template.json 2 3 --network testnet

To generate a FLIX, see the FLIX CLI readme.

Arguments​

  • Name: argument
  • Valid inputs: valid cadence values matching argument type in script code.

Input arguments values matching corresponding types in the source code and passed in the same order. You can pass a nil value to optional arguments by executing the flow script like this: flow scripts execute script.cdc nil.

Flags​

Arguments JSON​

  • Flag: --args-json
  • Valid inputs: arguments in JSON-Cadence form.
  • Example: flow scripts execute script.cdc '[{"type": "String", "value": "Hello World"}]'

Arguments passed to the Cadence script in the Cadence JSON format. Cadence JSON format contains type and value keys and is documented here.

Block Height​

  • Flag: --block-height
  • Valid inputs: a block height number

Block ID​

  • Flag: --block-id
  • Valid inputs: a block ID

Signer​

  • Flag: --signer

Specify the name of the account that will be used to sign the transaction.

Proposer​

Arguments JSON​

  • Flag: --args-json
  • Valid inputs: arguments in JSON-Cadence form.
  • Example: flow transactions send ./tx.cdc '[{"type": "String", "value": "Hello World"}]'

Arguments passed to the Cadence transaction in Cadence JSON format. Cadence JSON format contains type and value keys and is documented here.

Gas Limit​

  • Flag: --gas-limit
  • Valid inputs: an integer greater than zero.
  • Default: 1000

Specify the gas limit for this transaction.

Host​

  • Flag: --host
  • Valid inputs: an IP address or hostname.
  • Default: 127.0.0.1:3569 (Flow Emulator)

Specify the hostname of the Access API that will be used to execute the command. This flag overrides any host defined by the --network flag.

Network Key​

  • Flag: --network-key
  • Valid inputs: A valid network public key of the host in hex string format

Specify the network public key of the Access API that will be used to create a secure GRPC client when executing the command.
