Prepare a deposit into or withdrawal from an ACCRUE vault for the calling agent's own wallet. Nothing is signed or sent. Returns (1) eth_path: ordinary unsigned transactions to send in order from the account, paying gas in ETH — ALWAYS returned; (2) sponsored_path: when the wallet is eligible and within its limits, ACCRUE pays the network fee — sign the EIP-7702 authorisation if asked (first use on the chain), then call build_user_operation, which returns the operation with the sponsorship already approved; and (3) usdc_path: when available, the account can instead pay gas in USDC and hold no ETH at all — sign the returned USDC permit (and, on first use on the chain, the EIP-7702 authorisation, which keeps your address), then call build_user_operation. Prefer sponsored_path, then usdc_path; eth_path always works. The USDC path shows a gas ceiling: the most the operation can cost; the actual charge is lower. Every precondition is checked first (allowlist, minimum deposit, balance, withdrawable liquidity), so a failure is reported before you sign anything. Amounts are in USDC, e.g. "25" or "12.5"; for a full withdrawal use amount "all".
