One call for a transfer, a contract call, or a signature. Asset, recipient, amount. Or full bytes. - 02 · Evaluate ### See it before it goes. Simulate the result as a fork, decode the call into plaintext, and run the policy before a single byte goes onchain. - 03 · Broadcast ### Sign, sequence, send. Nonces and UTXO are reserved atomically, fees estimated and applied, nodes geo-redundant with active-active failover. - 04 · Track ### Watch it land. Recover if it doesn't. Webhooks fire on every state change. Stuck transactions will be reindexed, retried, sped up, or cancelled. Observable end to end.
