Frequently asked questions.

No. Shard has zero access to your funds at any point. Polymarket operates on a Gnosis Safe system — a smart contract wallet controlled exclusively by your address. Neither Polymarket nor Shard can interact with your wallet or move your funds without your explicit signature on a transaction. Every on-chain action requires your direct approval. Shard operates purely as a terminal layer on top of this infrastructure. We never touch your wallet, your keys, or your approvals.

Yes. Shard does not introduce any additional attack surface to your funds. Since we operate above Polymarket’s infrastructure with no custody over your assets, your security posture is identical to using Polymarket directly. For maximum transparency on every transaction, we recommend using Rabby Wallet — it provides a detailed breakdown of each transaction before you sign, so you always know exactly what you’re approving.

Neither is required. Shard gives you two options. You can create a new account directly through Shard, built on Polymarket’s infrastructure — meaning identical results and identical security to a native Polymarket account. Or you can simply connect your existing Polymarket account and pick up right where you left off. No fund transfers, no new wallet, no additional approvals required.

Shard does not introduce any custom smart contracts into the trading flow. We build on top of Polymarket’s builder SDK, which has itself been audited. All on-chain interactions go through Polymarket’s existing and battle-tested infrastructure. There is no additional contract layer on our end.

Shard interacts exclusively with Polymarket’s native smart contracts — the same ones used when trading directly on Polymarket. No additional contracts, no additional exposure.

Shard only requests the minimum permissions necessary to display your positions and execute trades on your behalf — and only when you explicitly initiate an action. We never request broad wallet permissions or approvals beyond what a specific transaction requires.

Never. Shard has no access to your private key or seed phrase at any point. Your keys never leave your wallet. All transaction signing happens locally in your wallet; Shard only receives the signed output, nothing more.

Nothing. Your funds are held in your Gnosis Safe — not on Shard. If Shard were to shut down tomorrow, your assets would remain fully intact and accessible directly through Polymarket or any other compatible interface. Shard is a terminal, not a custodian.

Your USDC are held in your personal Gnosis Safe smart contract wallet on-chain. They are not held by Shard, not held by Polymarket, and not held by any third party. You are the sole controller of that address.

Yes. All trades executed through Shard are on-chain transactions settled on Polymarket’s infrastructure. Every position is fully verifiable on-chain, independently from Shard.

Yes. Since all trades are on-chain, you can verify your positions at any time directly on Polymarket or through any on-chain explorer. You are never dependent on Shard to access or confirm your positions.

The risks are the same as using Polymarket directly: smart contract risk inherent to Polymarket’s infrastructure and standard market risk. Shard does not add any additional layer of risk to your funds or your trading activity.

If Shard goes down, you lose access to the Shard terminal but your funds and positions remain fully intact and accessible through Polymarket directly. If Polymarket goes down, both interfaces are affected since Shard is built on top of Polymarket’s infrastructure. In either scenario, your on-chain assets are never at risk.
