Sponsor Gas

Install the CLI and sign in. Replace the example account ID, session-key ID, and recipient with your own. Use an active key installed on Base Sepolia with permission for the operation.

The transfer amount and gas budget are different. Even with sponsored gas, the account must hold the assets you are transferring.

Sponsored execution is subject to the account's permissions and Namera's applicable limits. An interactive execution prompts for sponsorship and defaults to Yes.

Set sponsorship to false and approve an explicit maximum total gas cost in wei:

namera execution execute \
  --namespace evm \
  --wallet 0199dfe1-0000-7000-8000-000000000001 \
  --session-key 0199dfe1-0000-7000-8000-000000000002 \
  --network 'Base Sepolia' \
  --to 0x2222222222222222222222222222222222222222 \
  --value 1000000000000000 \
  --data 0x \
  --sponsor false \
  --max-gas-cost-wei 1000000000000000

Here the transfer is 0.001 ETH and the gas ceiling is another 0.001 ETH. The ceiling is not a gas estimate or a promise that this amount will be spent. An operation whose prepared cost exceeds the ceiling is rejected.

For --params, put "sponsor": false in the request and pass --max-gas-cost-wei as a separate CLI option.

Set an Agent's CeilingCopy Anchor Link

namera mcp serve --profile agent --max-gas-cost-wei 1000000000000000

Configure that option in the command your MCP client launches. Without a ceiling, the process permits sponsored operations only. A tool call cannot raise it.

Save the submission ID and track it. Do not repeat the execution to check progress.

Example output uses fixture accounts and hashes, captured with the CLI's output formatters. Plain-text output is shown without terminal colors; your values and relative expiry dates will differ.
