In the SDK

Wire Tatum via the chainkit builder

The builder accepts every provider you want in rotation. chainkit handles failover, retries, and scoring across them — pick capability coverage, not a single vendor.

import (
  "github.com/exapsy/chainkit"
  "github.com/exapsy/chainkit/bitcoin/providers"
  bttypes "github.com/exapsy/chainkit/bitcoin/types"
)

p := providers.NewTatum(/* opts — see godoc */)

client, _ := chainkit.NewMixedProvidersBuilder().
  WithProvider(p).
  Build(ctx)

Snippet illustrative; refer to the godoc for the exact constructor signature.
