Feegrant

Transaction commands for the feegrant module, which allows one account to grant fee allowances to another. This is useful for dVPN applications that want to sponsor transaction fees for their users.

Grant a Fee Allowance​

Grant a fee allowance to an address, allowing them to use the granter's funds for transaction fees.

sentinelhub tx feegrant grant \
  <granter_address> \
  <grantee_address> \
  --spend-limit <amount>udvpn \
  --from <key_name> \
  --chain-id sentinelhub-2 \
  --gas-prices 0.5udvpn \
  --gas 300000 \
  --node https://rpc.sentinel.co:443

You can also set an expiration with the --expiration flag (RFC 3339 timestamp).

Revoke a Fee Allowance​

Revoke an existing fee grant from a grantee.

sentinelhub tx feegrant revoke \
  <granter_address> \
  <grantee_address> \
  --from <key_name> \
  --chain-id sentinelhub-2 \
  --gas-prices 0.5udvpn \
  --gas 300000 \
  --node https://rpc.sentinel.co:443
