The Sandbox Bridge
The Sandbox Bridge is a helpful tool to shift your content between blockchain networks. Learn everything you need to know about The Sandbox Bridge and how to use it.
The Sandbox interacts with the Ethereum and Polygon blockchain layers. Here, we offer documentation on the basic steps you'll need to transfer your wallet contents between layers.
See The Sandbox Medium for updated information about The Sandbox Bridge:
The Ethereum blockchain is a decentralized platform with a Proof of Work consensus mechanism that enables users to conduct secured peer to peer digital transactions and is, as such, a popular option for dApps.
In contrast Polygon is built on top of the Ethereum blockchain as a Layer 2 scaling solution that uses a Proof of Stake (PoS) mechanism. As it is built on a different layer of the blockchain, you can expect less of the layer 1 frictions:
- Faster transaction speed.
- Less gas fees.
- Greener interactions on the blockchain.
RECOMMENDED: TRANSFER ASSETS TO POLYGON
To interact with all of our upcoming features, benefit from a LAND multiplier on your SAND staking, stake your SAND on one of our two staking programs, purchase a LAND in one of our upcoming LAND sales and much more, you will need assets on the Polygon network. This is where you will need to use The Sandbox Bridge.
Note that some Marketplace items may still be on the Ethereum network.
The Sandbox bridge will enable you to transfer your LANDs and SAND from the Ethereum blockchain to Polygon's Layer 2 and vice versa. Both LAND and SAND will now be fully supported on Polygon’s network and you will be able to interact with them in a single place: https://sandbox.game/en/me/bridge.

Pending Transactions & History
A Proof of Stake bridge, commonly referred to as a PoS bridge enables transfer of tokens between layers (Ethereum layer 1 and Polygon layer 2 in our case). The PoS bridge works in two steps: tokens are first sent from the initial network, reaches a checkpoint halfway through the transfer, then successfully finalizes the move to the target network.
The Sandbox created a custom bridge that allows users to quickly transfer their LAND, SAND and soon ASSET and EXPERIENCE tokens to their smart contracts on the Polygon network.
Using the bridge only moves your tokens from one blockchain to the other. It doesn't interfere with anything else. In all matters it is the same token, only on a different blockchain.
- The supply remains unchanged
- The value remains unchanged
- The utility remains unchanged
The Sandbox Bridge is designed to increase interoperability between the Polygon and Ethereum blockchains. With The Sandbox Bridge you will be able to move your SAND and LAND from one to the other.

POTENTIAL BLOCKERS
If you do not get a prompt from your wallet asking you to confirm the transaction, disable all adblocking and pop-up blocking extensions on your browser temporarily, and try again.
If there is still no wallet prompt, then try a different browser. Particularly if you are using Brave, which our The Sandbox community members report doesn't always behave nicely with non-Brave wallets.
TRANSACTION TIMING
It can take ten minutes to an hour for transferred LANDs or SAND to be reflected in your wallet depending on network congestion. There may also be a few minutes delay for your account at The Sandbox to update and reflect completed transactions.
TRACKING YOUR TRANSACTIONS
You need to use PolygonScan when tracking transactions on the Polygon network, not Etherscan, which is for transactions on the Ethereum network.
Use Polygon's Bridge Explorer to check the status of your transaction and unblock if needed. Enter your wallet address in the search box to find your pending transaction.
You can check your Transaction History or see the status of a pending transaction at The Sandbox Bridge. Pending transactions will note what step your transaction is at and if there are any actions required from you to continue the process.
