Post to the blockchain
Compose, sign, and submit a transaction to the blockchain. An enterprise wallet (Hardware Security Module or HSM) must be configured in the MultiBaas deployment. An HSM address will be used to sign the transaction (web3 browsers such as MetaMask will not work to sign transactions in Google Sheet).
- For example, MBPOSTTEMPLATE might output:
| address |
contract |
method |
from |
signer |
input0 |
txHash (output) |
- Enter parameters under each column name as follows. Multiple rows can be entered for multiple transactions.
| address |
contract |
method |
from |
signer |
input0 |
txHash (output) |
| oootoken |
mltitoken |
mint |
0xF9450D254A66ab06b30Cfa9c6e7AE1B7598c7172 |
0xF9450D254A66ab06b30Cfa9c6e7AE1B7598c7172 |
100 |
|
- Drag and select all of the parameters entered, across one or more rows. Go to Add-ons > MultiBaas for Google Sheets > Post to the blockchain
- The txHash (output) will be filled in as each transaction is submitted to the blockchain:
| address |
contract |
method |
from |
signer |
input0 |
txHash (output) |
| oootoken |
mltitoken |
mint |
