Copper — institutional custody with ClearLoop trading
Copper's Walled Garden custody plus ClearLoop trading network combine into a serious institutional setup. We reconcile both into one audit trail.
Copper.co serves institutional clients with cold-storage custody (Walled Garden), MPC custody, and ClearLoop — a network for trading on connected exchanges without moving funds out of custody. For a finance team running Copper, the accounting needs to capture custody balances and ClearLoop trading PnL together. We do.

The connection in 4 steps
Generate a read-only Copper API key
In the Copper institutional portal, create an API key with account and transaction read permissions. Add Wag3s to the IP allowlist if your Copper configuration requires IP restriction.
Connect Walled Garden and MPC custody to Wag3s
Enter your API key in Wag3s. We discover all Copper portfolios, Walled Garden cold-storage vaults, and linked MPC wallets. Each portfolio maps to a Wag3s entity.
ClearLoop trading activity classified
Trades executed via ClearLoop are ingested with the exchange counterparty, timestamp, and realized P&L computed per cost-basis method. Because funds never leave custody, the trades are classified as in-custody exchanges.
Custody balances reconciled on-chain and posted to ERP
Copper-reported balances are reconciled against independently computed on-chain truth per asset. Reconciled activity posts to your ERP on the daily schedule.
Common configurations
Fund executes spot and derivatives trades on multiple exchanges via ClearLoop, keeping assets in Copper Walled Garden cold storage. Wag3s reconciles ClearLoop trade P&L against custody movements and produces the monthly fund NAV schedule without moving assets off the Copper network.
Company holds a BTC treasury in Copper's Walled Garden. Annual audit requires proof that BTC balances match on-chain. Wag3s reconciles Copper's stated balance against on-chain independently and signs off the reconciliation report for the auditor.
Copper integration questions
How does ClearLoop affect accounting?
ClearLoop trades execute without moving funds out of custody. The realized P&L is booked to the right account; custody balance updates reflect the new asset mix.
How is ClearLoop off-exchange settlement treated in accounting?
ClearLoop allows trades to settle without assets leaving Copper Walled Garden custody. From an accounting perspective, each ClearLoop trade is recorded as an in-custody exchange — a disposal of the sold asset and an acquisition of the bought asset at trade price, with realized P&L computed per cost-basis method. Because no on-chain transfer occurs, Wag3s relies on the Copper API transaction record rather than on-chain data, and reconciles the resulting balance change against independent on-chain truth at the vault level.
Does Wag3s support all blockchain networks available in Copper?
Wag3s supports all chains on which Copper offers custody and for which Wag3s has a chain integration — including Bitcoin, Ethereum, Solana, Polygon, BNB Chain, and the main EVM L2s. For assets on chains not yet in the Wag3s chain catalog, custody balances are tracked at the portfolio level from Copper API data, with on-chain verification added as each chain is onboarded to the platform.
