Gas

Privy sponsorship for workflow writes and USDC gas on Arc.

Workflow writes call Privy wallet RPC with sponsor: true. You do not fund ETH for those steps on supported chains.

On Arc, gas is USDC:

• Native gas USDC is 18 decimals
• The ERC-20 USDC interface and marketplace amounts are 6 decimals at 0x3600000000000000000000000000000000000000

Do not mix those units in the same field.
