Refresh Cache

Force a resync of the caller's cached chain state

post

Clears the enclave's cached encrypted outputs for the caller's address so the next read re-fetches fresh state from chain. Requires an active session — include x-hinkal-request-signature: secp256k1_sign(SHA256("POST /refresh-cache\n" + JSON.stringify(body))) in the headers. Works for EVM, Tron, and Solana.

Header parameters

x-hinkal-request-signaturestringRequired

Hex-encoded compact secp256k1 signature: secp256k1_sign(SHA256(binding + "\n" + payload)), where binding is "<METHOD> <routePath>" (this route's own method and path, e.g. "POST /refresh-cache" or "GET /balance") and payload is JSON.stringify(body) for POST requests or the raw query string for GET requests. Binding the route into the signed digest stops a signature captured for one endpoint from being replayed against another. See Authentication for the full signing scheme.

Body
