This endpoint broadcasts a transaction your client has already constructed and signed. It is useful for wallets and advanced clients that want complete control over the Substrate signing payload. The Directory does not sign the transaction and cannot recover or modify it.

Send only the signed extrinsic. Never include a private key, mnemonic, seed phrase, or additional JSON fields.

Request

string

required

A 0x-prefixed hexadecimal SCALE extrinsic with the signed bit set.

The body must contain exactly this one field.
