astra.bid

Astra.bid was a browser-based wallet and order-routing tool for trading on Polymarket, holding an externally owned account whose private key lived only in the trader's browser rather than on a company server. Positions and USDC balances sat on Polygon, and some accounts routed extra funds into a Safe smart wallet controlled by that same key, a structure that kept custody with the trader rather than with Astra itself.

The operator has since shut the product down. Across its history the address attracted $25K in attributed volume and currently sits at #337 on the all-time leaderboard, but recent activity has gone quiet: $0 in the last seven days, 0 fills, and 0 wallets in the active trader cohort. Figures run through 2026-09-14, and the site itself now serves only as a recovery tool for wallets that traded there before it closed.

Connecting to Astra meant generating or importing a wallet whose private key stayed inside the browser's local storage; the operator's own instructions confirm keys never left the device. Trading ran through that embedded EOA, with order flow reaching Polymarket's order book on Polygon rather than through a separate custodial ledger, and some balances sat behind a Safe smart wallet that the EOA controlled, adding a second address a trader would need to track.

That architecture is now only relevant to recovery. Since the shutdown, the astra.bid site no longer accepts new trades or deposits; instead it scans the visiting browser's local storage for a stored key and, if found, displays it for export into MetaMask or another EVM wallet. A trader has to return to the exact browser and device used originally, since keys were never synced to a server or account the operator could look up. Recovering funds held in the linked Safe requires a second step: finding the Safe's address on Polygon's block explorer from the EOA, then connecting through the Safe's own web app to move USDC and positions out.

Nothing here routes fresh orders anymore. The only live function is the export flow described above, and it holds nothing of the trader's on a server; whatever remains sits in Polygon-based wallets the trader already controlled.

• Client-side key export

  Recovers a private key straight from browser storage for import into MetaMask, but only works on the original device and browser.

• Safe smart wallet detection

  Flags a linked Safe holding extra USDC or positions, though a trader must locate and unlock it manually via Polygon's explorer.

• No live order routing

  The order-routing side of the product is fully disabled, so it functions solely as a one-time exit tool, not an ongoing trading venue.

Former Astra users with a leftover wallet

Fits traders who once connected an Astra wallet and now need to move stranded Polygon funds into a wallet they can still access.

Traders who kept the original browser

The recovery tool only works from the exact browser and device that stored the key, so it fits someone who never wiped that setup.

Wallets linked to a Safe

Suits traders whose Astra wallet controlled a Safe smart wallet, since exporting the EOA key is the first step to reaching those funds too.

Anyone shopping for a live Polymarket wallet

Does not fit at all: routing fresh funds through astra.bid is not possible since new trading and deposits have been switched off entirely.

Astra.bid never published a fee schedule, leaving no advertised rate for traders to reference. That gap barely matters now: the platform shows $0 in current volume and 0 fills over the last week, so there is no live order flow left to price at all. Anyone still holding a balance from Astra's active period should treat any cost from that period as sunk, and weigh instead the gas spent on Polygon to move funds out through MetaMask or a linked Safe, the only expense left to consider.

• Keeps custody with the trader by storing the wallet's private key only in the browser rather than on Astra's servers.
• Offers a working export path into MetaMask for anyone who still has the original browser and device.
• Surfaces a linked Safe smart wallet so a trader knows to check for a second pool of stranded funds.
• Built up $25K in attributed volume before closing, showing it once carried real order flow rather than being untested.
• States plainly that Astra has shut down instead of leaving the site running as if nothing changed.

• Has shut down entirely, so no trader can route new orders or deposits through it today.
• Never published a fee schedule, leaving no rate on record from when it was active.
• Offers no way to recover funds for a trader who no longer has the original browser or device.
• Requires a separate manual step through Polygon's explorer and the Safe web app to reach funds held in a linked Safe.
• Gives no operator contact point beyond the automated recovery page for anyone who runs into trouble.

Custody here was always self-directed: Astra's own instructions confirm the private key sat only in browser storage and never touched a company server, which limits what a shutdown can take from a trader but also means nobody but the trader can recover a lost key. Transparency is thin outside that one page; the operator states the shutdown plainly but does not explain why it happened or what became of the underlying business. The main operational risk now sits with the recovery process itself: pasting a private key anywhere other than a wallet's own import screen hands an attacker everything, and the linked Safe adds a second address a trader has to secure correctly.

Astra.bid is not a decision a trader makes anymore; it is a dead end with a recovery hatch. The product accumulated $25K in attributed volume across its life and ranks #337 by that measure, but it has posted $0 and 0 fills over the last week, and the operator's own page confirms the shutdown rather than leaving it ambiguous. Anyone who traded on Astra before it closed should use the export tool to pull funds into MetaMask and check for a linked Safe. Nobody should treat it as a place to route new money, because that option no longer exists.

• Is astra.bid still active?

  No. The operator shut Astra down and the site now only helps former users export a browser-stored private key into MetaMask to reach leftover funds on Polygon.

• Is astra.bid safe to use?

  The key export tool only reads local browser storage and never sends the key anywhere, but pasting that key into any site other than a wallet's own import screen would expose it.

• Does astra.bid charge trading fees?

  The operator never published a fee schedule while the product was active, and the question is moot now since new trading and deposits have been switched off entirely.

• How do I recover funds from astra.bid?

  Open the site in the exact browser and device used to trade, export any private key found in local storage, then import it into MetaMask and switch to Polygon.

• What happened to astra.bid?

  The operator shut the product down; its site now functions only as a one-time recovery tool rather than a live Polymarket wallet or order-routing venue.

• What if I no longer have the browser I traded from?

  The recovery page finds keys only in that browser's local storage, so a trader who switched devices or cleared storage has no listed way to retrieve the key through astra.bid.

• Are there alternatives to astra.bid for trading on Polymarket?

  Astra.bid no longer routes any order flow, so anyone looking to trade should compare active, currently ranked builders on Predicts.guru's leaderboard rather than this one.
