AI agents use build_stake_txs to commit financial operations through Logiqical — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Staking involves committing financial assets (ARENA tokens) to a staking contract via approve and deposit transactions. While these are unsigned transactions (requiring a subsequent broadcast), the tool directly facilitates financial commitment of crypto assets. Given the financial nature of staking on Avalanche trading infrastructure, this falls under Financial category.
