2.1.3 Build multi-output transaction​

To build a multi-output transaction, you need to prepare a file in CSV format that specifies the recipient's address and amount. For example: addresses.csv

EY55SertfPSAiLxgYGQDUdxQW6eDZjbNbX,0.001
Eeqn3kNwbnAsu1wnHNoSDbD8t8oq58pubN,0.002
EXWWrRQxG2sH5U8wYD6jHizfGdDUzM4vGt,0.003

The first column is the recipient's address and the second column is the amount. (note that the above is sample data, and you need to fill in your own data when sending the real transaction)

Specify the addresses.csv file with the β€”tomany parameter.

./ela-cli wallet buildtx --tomany addresses.csv --fee 0.001

Result：

Multi output address: EY55SertfPSAiLxgYGQDUdxQW6eDZjbNbX , amount: 0.001
