Stake mSAND (Polygon)
Information and guidance about staking mSAND through Biconomy's gasless transaction service at The Sandbox.
In February 2022, The Sandbox introduced gasless mSAND staking through a service called Biconomy. This program is open to everyone on the Layer 2 Polygon network, where 500,000 mSAND in rewards will be added each week for the first four weeks.
Apart from any fees that it might initially cost to bridge SAND from the Ethereum network to the Polygon network, staking mSAND in this program is gasless, provided that you haven't used up your monthly quota of gasless transactions.
This staking program is, in particular, a great opportunity for those who are new to staking, before considering getting involved in some of the more "heavier" staking programs, such as SAND-ETH staking and mSAND-MATIC staking.
mSAND holders who provide liquidity to the program will be eligible to share a monthly allocation of 500,000 mSAND.
Rewards are distributed pro-rata, relative to a trader’s percentage of total liquidity over the course of a one-week period.
You can claim your rewards from this pool once per week (or every 7 days).
If you do not currently hold any mSAND, you can bridge your SAND to mSAND using a swap service. There is an easy-to-use bridging service integrated on The Sandbox website. See our guide on bridging SAND to mSAND if needed:
Note that your wallet needs to be switched to the Polygon Mainnet network, in order to stake on Polygon's Layer 2 network. If you have not set this up in your wallet yet see our guide:

Through Biconomy, The Sandbox offers different ways to go through gas fees related to staking.
- Gasless: The Sandbox offers you 10 free gasless transactions per month. This means that you can stake more mSAND or withdraw from your existing pool without having to pay additional fees.
- Forward: This new feature will have the possibility to use your mSAND to pay your gas fees in lieu of MATIC.
- Classic: You still have the option to pay your gas fees using MATIC
The Gasless feature is enabled by default, and you can enable the Forward feature directly in your chain settings.
Head on over to the Staking Dashboard on The Sandbox website: https://www.sandbox.game/en/me/defi/
Locate the mSAND staking option and press the Approve button.

Sign the transaction confirmation that should appear. If gasless is enabled, this transaction will go through Biconomy, our trust forwarder.

Once approved, you will see the option to deposit. Click the Deposit button to access the deposit panel.

Choose the amount of mSAND to deposit. Confirm this and then sign the transaction confirmation in your wallet. Again, if "Gasless" or "Forward" is enabled, the transaction will go through Biconomy.
