Sharded Wallet

Overview

Sharding can refer to secret shares, threshold signers, separate asset or network partitions, customer groups, or horizontally scaled wallet services. The design aims to reduce concentration, improve capacity, or isolate failures.

The term is not one standardized custody model. Some shards may reconstruct one key, while others independently control separate funds. Shared coordinators, administrators, databases, or recovery credentials can reintroduce central risk. Incorrect routing or incomplete shard inventory can make assets inaccessible.

Architecture should define what is sharded, ownership, quorum, data consistency, failure domains, and recovery. Transaction requests need deterministic routing and idempotency. Teams should test loss, compromise, and unavailability of each component. Consolidated reporting must reconcile every shard without granting one monitoring service unnecessary signing authority.

Sharded Wallet should be distinguished from the asset balance and from the application that displays it. For example, a customer-facing success message does not prove that the intended transaction executed on the correct network; operations should verify execution and reconcile the result before irreversible fulfillment.

Records for Sharded Wallet should preserve account and address identifiers, asset and network identity, policy version, requester, approvers, signed payload or transaction reference, fees, timestamps, status history, confirmations, exceptions, and final balance and accounting effects. For Sharded Wallet, corrections must remain linked rather than overwrite the original event.

The Sharded Wallet workflow operates through several distinct states: request creation, user or policy approval, signature generation, network submission, execution, confirmation, balance recognition, and accounting. For Sharded Wallet, a wallet interface or provider response can report progress, but it cannot replace verified transaction and ledger evidence.
