FLOW Token Management
How to mint FLOW Token
Some actions on the network will require an account to have a certain amount of FLOW (tokens) - transaction and storage fees, account creation, etc.
Framework provides a method to query FLOW balances with getFlowBalance and mint new tokens via mintFlow.
getFlowBalance(address)
Returns current FLOW token balance of the specified account.
Arguments
| Name | Type | Description |
|---|---|---|
address | Address | address of the account to check |
Returns
| Type | Description |
|---|---|
string | UFix64 amount of FLOW tokens stored in account storage |
Usage
import {
init,
emulator,
getAccountAddress,
getFlowBalance,
} from "@onflow/flow-js-testing"
const main = async () => {
const basePath = path.resolve(__dirname, "../cadence")
await init(basePath)
await emulator.start()
const Alice = await getAccountAddress("Alice")
const [result, error] = await getFlowBalance(Alice)
console.log(result, error)
await emulator.stop()
}
main()
mintFlow(recipient, amount)
Sends transaction to mint the specified amount of FLOW and send it to recipient.
⚠️ Required: Framework shall be initialized with
initmethod for this method to work.
Arguments
| Name | Type | Description |
|---|---|---|
recipient | Address | address of the account to check |
amount | string | UFix64 amount of FLOW tokens to mint and send to recipient |
Usage
import {init, emulator, mintFlow} from "@onflow/flow-js-testing"
const main = async () => {
const basePath = path.resolve(__dirname, "../cadence")
await init(basePath)
await emulator.start()
const Alice = await getAccountAddress("Alice")
const amount = "42.0"
const [mintResult, error] = await mintFlow(Alice)
console.log(mintResult, error)
await emulator.stop()
}
main()
