Body Params

Amount to transfer as a numeric string in the chain's human-readable units (e.g. ETH, BTC, SOL, TRX, XRP), or the literal string "max" to send the entire available balance net of fees/reserves.

string

Optional HD (BIP44-style) derivation path. Use when the vault has multiple addresses on the same chain and you want to target a specific one. Format is m/<index>/<index>/... using only non-hardened (unprimed) indexes.

When true, skip fee-affordability validation; the transaction is still built and returned. The caller assumes responsibility for fee/balance sufficiency. Cannot be combined with amount "MAX" — provide an explicit amount instead.
