sendBatch submits independent transactions together on /hofund. Each member is dispatched on its own; the result lists one signature per member in request order.
Parameters
string[]
required
1 to 25 fully signed transactions, canonical padded base64, at most 1232 bytes each, no duplicates.
object
{} or exactly { "mevProtect": <boolean> }. true sends every member through Jito instead of the fast rails. ?mev-protect=true is not accepted with JSON sendBatch; use this field.maxProtectedBatchTransactions and protectedBatchTimeoutMs from getThorTipConfig before sizing a protected batch. Exceeding it returns -32602 protected sendBatch exceeds the configured maximum.
Response
string[]
Signatures in the same order as
params[0].X-Hofund-Submission-ID. A batch outcome that cannot be resolved returns -32007 transaction batch outcome is ambiguous.
