send

Send a payment transaction to the network.

Basic usage​

mina wallet send \
  --from /path/to/encrypted/key \
  --to <receiver_public_key> \
  --amount <amount_in_nanomina> \
  --fee <fee_in_nanomina>

Arguments​

Required:

  • --from <PATH> - Path to encrypted sender key file
  • --to <PUBLIC_KEY> - Receiver's public key (Base58Check encoded)
  • --amount <AMOUNT> - Amount in nanomina (1 MINA = 1,000,000,000 nanomina)
  • --fee <FEE> - Transaction fee in nanomina

Optional:

  • [PASSWORD] - Password to decrypt the sender key. Can be provided as an argument or via the MINA_PRIVKEY_PASS environment variable (recommended for security)
  • --memo <MEMO> - Transaction memo (max 32 bytes, default: empty)
  • --nonce <NONCE> - Transaction nonce (default: fetched from node)
  • --valid-until <SLOT> - Slot until which transaction is valid (default: never expires)
  • --fee-payer <PUBLIC_KEY> - Optional fee payer public key (default: sender pays)
  • --network <NETWORK> - Network for signing: mainnet or devnet (default: devnet)
  • --node <URL> - Node GraphQL endpoint (default: http://localhost:3000)

Examples​

Send payment on devnet​

mina wallet send \
  --from ./keys/my-wallet \
  --to B62qre3erTHfzQckNuibViWQGyyKwZseztqrjPZBv6SQF384Rg6ESAy \
  --amount 1000000000 \
  --fee 10000000 \
  --network devnet

Send payment on mainnet with memo​

mina wallet send \
  --from ./keys/my-wallet \
  --to B62qre3erTHfzQckNuibViWQGyyKwZseztqrjPZBv6SQF384Rg6ESAy \
  --amount 5000000000 \
  --fee 10000000 \
  --memo "Payment for services" \
  --network mainnet

Send payment with separate fee payer​

mina wallet send \
  --from ./keys/sender-wallet \
  --to B62qre3erTHfzQckNuibViWQGyyKwZseztqrjPZBv6SQF384Rg6ESAy \
  --amount 1000000000 \
  --fee 10000000 \
  --fee-payer B62qkfHpLpELqpMK6ZvUTJ5wRqKDRF3UHyJ4Kv3FU79Sgs4qpBnx5RG

Send payment to remote node​

mina wallet send \
  --from ./keys/my-wallet \
  --to B62qre3erTHfzQckNuibViWQGyyKwZseztqrjPZBv6SQF384Rg6ESAy \
  --amount 1000000000 \
  --fee 10000000 \
  --node https://node.example.com:3000

Use environment variable for password​

export MINA_PRIVKEY_PASS="my-secret-password"

mina wallet send \
  --from ./keys/my-wallet \
  --to B62qre3erTHfzQckNuibViWQGyyKwZseztqrjPZBv6SQF384Rg6ESAy \
  --amount 1000000000 \
  --fee 10000000

How it works​

When you send a payment, the CLI:

  1. Decrypts your key - Uses the provided password to decrypt your private key
  2. Fetches nonce - Queries the node via GraphQL to get your current account nonce (if not specified)
  3. Creates payload - Builds the payment transaction payload with all details
  4. Signs transaction - Signs the transaction using your private key and the correct network ID
  5. Submits to node - Sends the signed transaction to the node via GraphQL sendPayment mutation
  6. Returns hash - Displays the transaction hash, which can be used with mina wallet status to track the transaction

Network selection​

The --network flag controls which network the transaction is signed for:

  • devnet - For development and testing (default)
  • mainnet - For production transactions

Important: Make sure to use the correct network flag. A transaction signed for devnet will not be valid on mainnet and vice versa.

Fee payer​

By default, the sender pays the transaction fee. However, you can specify a different fee payer using the --fee-payer option:

  • The sender's key is used to sign the payment
  • The fee payer's public key is included in the transaction
  • The fee payer must also sign the transaction (currently requires manual coordination)

This is useful for sponsored transactions where another party pays the fees.
