Controlled MPC Wallet Operations for Crypto Exchanges

A growing exchange needs clearer wallet control, signing policy, event delivery, and ledger records before deposit and withdrawal flows become harder to govern.

The challenges your team faces.

01

Wallet controls need to mature before volume

Omnibus hot-wallet routines become hard to defend as deposits, withdrawals, treasury movement, and approval paths grow.

02

Reconciliation cannot be patched later

Finance and operations need one operating record for deposits, withdrawals, internal transfers, fees, and wallet state.

03

Signing policy belongs in the operating flow

Withdrawal rules, limits, and approval paths need to be checked before MPC signing, not reviewed after funds move.

04

Network events must reach the product

Broadcast status, confirmations, and wallet lifecycle events need to feed the exchange stack through a stable API surface.

Wallet, signing, and ledger layer for exchange flows.

01

MPC wallets through API

Wallet creation becomes a repeatable API flow with signing policy and Co-Signer checks attached to wallet operations.

02

Operating ledger

Deposits, withdrawals, transfers, and fee movements are written into a ledger that finance and operations can reconcile.

03

Configurable policy and fees

Model withdrawal rules, fee behavior, and approval paths without hard-coding every operational change.

04

Network events

Broadcast status, confirmations, and wallet lifecycle events feed the product and operations stack through API and WebSocket surfaces.
