Parameters from the server's own tool schema.
Unfreezing TRX releases staked tokens back to liquid form, directly affecting financial holdings and resource commitments on the TRON blockchain. This is a financial operation that modifies the staking state of TRX tokens, which have real monetary value. Misuse could lead to unintended release of staked assets, affecting bandwidth/energy resources and token liquidity.
