What is StablePay?
StablePay is a decentralized payment platform in the Ethereum network secured by Smart contracts. StablePay allows you to send any tokens (ETH and ERC20s) and the receiving person gets a stable coin pegged to the USD (DAI).
Which are the uses cases for StablePay?
StablePay allows you:
  • Send or receive donations/tips to open source projects in Github/NPM in DAI.
  • Add a tip/donation button to your blog or content for accepting DAI instantly, your followers/readers can choose to pay with any token, you get DAI.
  • Send a personalized link to request payments via URLs that are safe to share on social apps, email or any other channel.
  • Integrates to your favorite wallet.
  • Track your sent and receive transfers in your personalized dashboard.
  • Get your DAIs instantly deposited to Compound to start earning interest immediately as soon as you get paid. (coming soon)
  • Get notifications on payments to your email or phone (coming soon).
How does StablePay works?
When you want to make a transfer with an ETH or an ERC20 token, StablePay checks the token requested for transfer and using an off-chain query we find the most suitable swapping provider out of our supported list (Uniswap, Kyber) and select the best match given criteria like liquidity, best price, etc. This selected provider it's then feeding into the contract as part of the transaction the user signs to send the transfer. This off-chain calculation is meant to lower gas costs for users of the platform. Since the contracts support multiple providers a user could feed manually any provider without the off-chain component as well.
Are the smart contracts audited by any independent security company?
Yes, the smart contracts are being audited by Quantstamp. After the audit process is fully complete we will be publishing the report and results of the audit.
Is StablePay safe? What is the risk?
We are fully a noncustodial platform thanks to the power of Ethereum’s smart contracts if the transaction is unable to finish for some reason, all funds are reverted back. In this case, you would only incur the gas costs and your funds will stay safe on your wallet. We do take security very seriously so we have implemented several measures and best practices to minimize the risk of funds being lost.
  • Our code is being audited by Quantstamp.
  • Our contracts don’t hold any user's funds after the transaction has been finalized.
  • Our platform will cap payments to a safe amount on launch as we test out the platform on mainnet. This amount will increase progressively after launch.
  • Our contracts are upgradable and pausable.
With all that said we like to note that there will always be risks with technologies like smart contracts, so usage of this platform falls entirely under the user's risk.
Can I cash out to Fiat my DAIs with StablePay?
We plan to support several integrations with partners that handle fiat off-ramps so our users can cash there DAIs and tokens to fiat. (coming soon)
What is Ethereum?
Ethereum is a global, decentralized platform for money and new kinds of applications. On Ethereum, you can write code that controls money, and build applications accessible anywhere in the world.
  • You can find a good in depth explanation here.
What is a Stable Coin?
A Stable Coin is a cryptocurrency that is pegged to another stable asset. On launch we will support DAI which is pegged to the US Dollar.
What is an ERC20 token?
ERC20 tokens exist on the Ethereum platform. The native currency on the Ethereum network is Ether. ERC20 is just a standard that specifies how these tokens work. This is a good video explaining them more in depth. here
What are the official channels of communication?
Official announcements are done using our official social accounts:
  • Twitter : @StablePay
  • Youtube: @StablePay
  • Telegram: @StablePay
  • Medium: @stablepayio
  • Reddit: @StablePay
StablePay ask for personal or payment information through Direct Message.?
StablePay will never ask any customer/user for personal or payment information through Direct Message. Please, verify our official channels of communication.
Why do I need to enable tokens for payment?
To send a token, the user must enable the token to allowance permission StablePay Smart contracts to move your token.
How is the exchange amount calculated in the checkout page?
We use an off-chain calculation that takes into account several criteria like liquidity, price, etc; out of the underlying swapping providers, given the selected token for payment, current prices and availability on supported dexes and gas cost of the transaction.
Can I get paid on different addresses?
The button widget is configured only to use one address. You can generate a different widget with different addresses and add them to your GitHub repo or website. We recommend that you use only one to keep better control of the transactions in your dashboard. We plan to add an aggregate dashboard and more support for addresses depending on the user’s feedback and feature priorities.
Can I configure my payments to be received in Ether or other tokens?
At launch will be supporting only DAI as receiving token, but we will add support for more tokens soon based on the user’s feedback.
Do you plan to support sending or receiving Bitcoins?
For the time being Stablepay will be focused on the Ethereum network and the tokens supported within the network, mainly Ether and ERC20s. With that said on launch, you’ll be able to pay with WBTC which is a token that represents bitcoins on the Ethereum network and soon after launch will enable support to receive WBTC tokens as payment coins.
Can I pay with my favorite XYZ ERC20 token using Stablepay?
We support most of the ERC20 tokens that have liquidity on our swapping providers (Uniswap and Kyber). If your favorite token is supported you will be able to use it with Stablepay. If your token is supported and you have trouble making payments with it send us an email to .
How can I verify whether an ERC20 token is supported or not by StablePay?
Here is the full list of tokens we currently support for payments. (list coming soon).Or send an email to if you are interested in a specific token you don’t see
What is the cost of using Stablepay?
Users making transfers through Stablepay will only incur the gas costs of the transaction. For users that intend to receive payments, configuring the widget and signup to the dashboard is free as well. All DAI payments to DAI payments are free of fees. If the paying user chooses any other token than DAI we charge a small service fee of 0.5 % of all amounts received. In the future, we plan to explore other funding models.
Can I receive my payments or donations directly to Compound?
Yes, we support receiving your DAI transfers supplied into Compound for you. We plan to support more loan protocols in the near future.
What other swapping providers do you plan to support?
The platform has been designed to be flexible enough to add support for many more DEXes and swapping providers, we will be asking feedback to our users to decide which providers make the most sense to integrate next. There are plans for 0x, air swap at the moment, but these may all change depending on priorities for other features.
Is StablePay open or decentralized?
Currently, the StablePay platform can be accessed by anyone like any other protocol on the Ethereum network.

The plan is to publish the backend code that supports the platform to be used and deployed by anyone and keep the option open to use your own APIs or use our existing API backend.

Fees are currently set for everyone using the platform and the admin address is controlled by the StablePay team while we improve the platform and continue improving it for all users.

As a long term plan we will explore options that would best suit the platform and our funding model, we are considering DAOs as a possible governance model, but priority number one is to improve and extend the platform.
How is StablePay funded?
MakerDao provided a small grant to develop and launch, for the most part, we are a self-funded team and open to other funding options. If you want to help with funding, please contact us at

Does StablePay have any guarantees against frauds or issues with the payments?
We currently don’t support any cashback policy or fraud protection, since the Ethereum smart contracts transactions once confirmed are final and no money can be returned after that.

For eCommerce and shopping, although is enabled, users run into all the risks we detailed above both for merchants and customers. There is no possible enforcement the platform can make to return stolen funds and locked out fraudulent websites.

The users are entirely responsible for their usage of the platform and no fraud protection or chargeback style of policy is possible as of now with Smart Contracts since this is digital money being exchanged directly.
