Grantee Transaction Process​

To initiate the transaction on behalf of the granter account, follow these steps:

The granter must first generate an offline transaction using the following command which prepares the transaction details and saves them in the tx.json file.

sentinelhub tx bank send \
  <granter_address> \
  <recipient_address> \
  <amount>udvpn \
  --chain-id sentinelhub-2 \
  --generate-only > tx.json

The grantee is then responsible for broadcasting the transaction. Ensure that the grantee has sufficient fees to cover the transaction costs. Use the following command:

sentinelhub tx authz exec tx.json \
  --from <grantee_key_name> \
  --node https://rpc.sentinel.co:443 \
  --chain-id sentinelhub-2 \
  --gas-prices=0.5udvpn \
  --gas=300000
