Transaction.GetInterchain and Block.GetInterchain take variadic options
(client.WithPerChain / client.WithChains, re-exported as sdk.WithPerChain /
sdk.WithChains) that map to the new prime-node ?perChain=&chains= query params.
Backward compatible: existing no-option calls get the default (one anchor per
chain). client.InterchainQuery builds the suffix; unit-tested.
NewClient hardcoded its *http.Client, so a server-side caller making
requests to an attacker-influenced baseURL (a tenant's prime_endpoint)
had no way to attach an SSRF policy — the transport followed redirects
and dialed any resolved IP, reachable being the cloud metadata service.
Add NewClientWithHTTPClient + NewDragonchainSDKWithHTTPClient so callers
can supply a client whose transport enforces a dial-time resolved-IP guard
and redirect policy. Existing constructors delegate with the prior default
(30s timeout), so this is backward compatible — the guard itself lives in
the consuming server (e.g. brill-api/pkg/prime), not in this client lib.
Enable request timeout and cancellation control by adding context.Context
as the first parameter to all SDK API methods. This allows users to:
- Set per-request timeouts
- Cancel in-flight requests
- Pass request-scoped values
