Command Syntax

npx agnic@latest send <amount> <recipient> [--chain <chain>] [--json]

Arguments

Argument Description

amount

Amount to send:

'$1.00'

1.00

, or atomic units (1000000 = $1). Always single-quote amounts that use

to prevent bash variable expansion. If the number looks like atomic units (no decimal or > 100), treat as atomic units.

recipient

Ethereum address (0x...) or ENS name (vitalik.eth)

Options

Option	Description
`--chain <name>`	Blockchain network (default: base)
`--json`	Output result as JSON

Input Validation

Before constructing the command, validate all user-provided values to prevent shell injection:

amount: Must match
```
^\$?[\d.]+$
```
(digits, optional decimal point, optional
```
$
```
prefix). Reject if it contains spaces, semicolons, pipes, backticks, or other shell metacharacters.
recipient: Must be a valid
```
0x
```
hex address (
```
^0x[0-9a-fA-F]{40}$
```
) or an ENS name (
```
^[a-zA-Z0-9.-]+\.eth$
```
). Reject any value containing spaces or shell metacharacters.

Do not pass unvalidated user input into the command.

USDC Amounts

Format	Example	Description
Dollar prefix	`'$1.00'` , `'$0.50'`	USD notation (single-quote the `$` )
Decimal	`1.0` , `0.50`	Human-readable with decimal point
Whole number	`5` , `100`	Interpreted as whole USDC tokens
Atomic units	`500000`	Large integers treated as atomic units

IMPORTANT: Always single-quote amounts that use

to prevent bash variable expansion (e.g.

'$1.00'

not

$1.00

ENS Resolution

ENS names are automatically resolved to addresses via Ethereum mainnet. The command will:

Detect ENS names (any string containing
```
.eth
```
)
Resolve the name to an address
Display both the ENS name and resolved address in the output

Examples

# Send $1.00 USDC to an address
npx agnic@latest send 1 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb7

# Send $0.50 USDC to an ENS name
npx agnic@latest send 0.50 vitalik.eth

# Send with dollar sign prefix (note the single quotes)
npx agnic@latest send '$5.00' 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb7

# Get JSON output
npx agnic@latest send 1 vitalik.eth --json
