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.
New Transaction.GetInterchain and Block.GetInterchain call the prime-node
/api/v1/{transaction,block}/{id}/interchain endpoints, returning an
InterchainTrace {blockId, validatorBlocks, interchainTransactions}. Adds local
VerificationBlock / InterchainTransaction / InterchainTrace model types.
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
