Function: feeOutputFromEstimate()

function feeOutputFromEstimate(__namedParameters): FeeOutput | null;

Defined in: @lelantos-org/sdk/dist/bundle/fee.d.ts:73

The fee slot for a spend, read straight off a relayer's estimate.

Prefer this to feeOutput: an estimate carries the address on one field and the amount on another, and picking the right quote out of fees[] means matching on assetId — three joins a caller would otherwise redo, and get subtly wrong, at every call site.

Returns null when the relayer is not charging on this chain (shieldedFeeAddress absent), which is the case where a spend needs no fee slot at all. Throws when it is charging but cannot take this asset — that is a spend which cannot be relayed, and silently omitting the fee would turn it into a 402 from the submit call instead.
