Support
This library supports the following blockchains:
This library supports the following wallets:
via WalletConnect:
DePay Payments
DePay Payments allows you to accept and perform crypto payments.
Preparation
In order to receive decentralized payments on any blockchain you need to have your own wallet on that particular blockchain first:
Quick start
<script src="https://integrate.depay.fi/widgets/v6.js"/>
DePayWidgets.Payment({
accept: [{
blockchain: 'ethereum',
amount: 20,
token: '0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb',
receiver: '0x4e260bB2b25EC6F3A59B478fCDe5eD5B8D783B02'
}]
});
Configuration
You need to pass a configuration object to DePayWidgets.Payment
which needs to at least contain the accept
field:
DePayWidgets.Payment({
accept: [{
blockchain: 'ethereum',
amount: 20,
token: '0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb',
receiver: '0x4e260bB2b25EC6F3A59B478fCDe5eD5B8D783B02'
}]
});
You can also accept multiple payments on multiple blockchains:
DePayWidgets.Payment({
accept: [
{ // 20 USDT on ethereum
blockchain: 'ethereum',
amount: 20,
token: '0xdac17f958d2ee523a2206206994597c13d831ec7',
receiver: '0x4e260bB2b25EC6F3A59B478fCDe5eD5B8D783B02'
},{ // 20 BUSD on bsc
blockchain: 'bsc',
amount: 20,
token: '0xe9e7cea3dedca5984780bafc599bd69add087d56',
receiver: '0x552C2a5a774CcaEeC036d41c983808E3c76477e6'
}
]
});
accept
blockchain
The blockchain you want to receive the payment on.
Currently supported:
ethereum
bsc
(Binance Smart Chain)
token
The address of the token you want to receive.
Use our payment configurator in order to simplify configuring this.
amount
(Optional)
The amount of tokens you want to receive. Needs to be passed as a human readable number e.g. 20
.
The BigNumber
of that amount will be calculated internally including finding the right amount of decimals for the given token.
So please just pass the amount in a human readable form as Number/Decimal: e.g. 20
for 20 USDT or 20.25
etc.
If you do not pass an amount, the user will be able to select an amount within the widget.
receiver
The address receiving the payment. Always double check that you've set the right address.
amount
When you want to control how the amount selection behaves, pass the amount
configuration object,
alongside values for start
, min
and step
.
start
: The amount that is initially selected.
min
: The minimum amount selectable.
step
: The number by wich to increment/decremten changes to the amount.
receiver
Payment receivers can either be wallet addresses, but also smart contracts.
In order to have smart contracts receive the payments you will need to pass an object as receiver containing the following attributes.
DePayWidgets.Payment({
accept: [
receiver: {
address: toAddress,
signature: 'claim(address,uint256,bool)',
params: ['true']
}
]
});
address
: The address of the smart contract.
signature
: The signature of the smart contract method you want to call as part of the payment.
params
: Additional params forwarded to the smart contract method.
Checkout DePay Web3 Payments and DePay Router Smart Contract for more details.
fee
You can configure a fee which will be applied to every payment with it's own dedicated fee receiver address.
The fee will be taken from the target token and target amount (after swap, depending on your accept
configuration).
amount
: Either percentage (e.g. 5%
, or absolute amount as BigNumber string ('100000000000000000') or pure number (2.5)
receiver
: The address that is supposed to receive the fee.
DePayWidgets.Payment({
accept: [...],
fee: {
amount: '3%',
receiver: '0x4e260bB2b25EC6F3A59B478fCDe5eD5B8D783B02'
}
});
fromToken, fromAmount + toToken
In case where you want to configure payments based on the source token + amount, rather than target token and amount, you can pass fromToken
, fromAmount
and toToken
to accept
.
In those cases make sure to NOT configure token
nor amount
!
DePayWidgets.Payment({
accept: [{
blockchain: 'bsc',
fromToken: '0xe9e7cea3dedca5984780bafc599bd69add087d56',
fromAmount: 0.1,
toToken: '0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE',
receiver: '0x08B277154218CCF3380CAE48d630DA13462E3950'
}]
});
// This will open a payment widget to send 0.1 BUSD to the receiver, converting it to BNB along the way.
track
track
Allows to track payment confirmation via DePay to enable integration into web applications.
DePayWidgets.Payment({
track: {
endpoint: '/track/payments' // your endpoint to forward the payment tracking to the payments api
}
})
Once the payment has been submitted by the widget, it will call the configured endpoint with:
POST /track/payments
BODY:
{
"blockchain": "ethereum",
"transaction": "0x4311a9820195c2a5af99c45c72c88848ed403a4020863c913feed81d15855ae4",
"sender": "0x769794c94e9f113e357023dab73e81dbd6db201c",
"nonce": 103,
"after_block": 13230369,
"to_token": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48"
}
Alternatively you can pass a method to track that performs the tracking request to your backend if you need to handle the request yourself (e.g. to add additional headers etc.):
DePayWidgets.Payment({
track: {
method: (payment)=>{
return fetch('/track/payments', {
method: 'POST',
body: JSON.stringify(payment),
headers: { "Content-Type": "application/json", "X-CSRF-TOKEN": document.querySelector('[name=csrf-token]').content }
})
}
}
})
In case you pass a tracking method it needs to return a promise.
Your endpoint needs to make sure to forward this to the payment tracking api.
Also make sure to add token
, amount
and confirmations
when forwarding the request to the payments api.
Those values are supposed to be set by your backend not the widget nor the fronted because any user could set these values to their liking otherwise, having you confirm payment amounts and tokens that you didn't intend to receive!
Make sure you read the Payment Tracking API for further details on how to integrate payment tracking.
Payment tracking requests will be attempted up to 3 times by the widget and will display "Payment tracking failed!" to the user if the widget was not able to start payment tracking via the given endpoint after 3 attempts.
A failed payment tracking will also call the error callback with {code: "TRACKING_FAILED"}
.
Additional Polling
In order to ensure a 100% coverage that users are released and forwarded within your payment flow, you will need to implement polling in addition to tracking.
The track.poll
configuration either takes an enpoint
or a method
(similiar to track itself).
It will use the endpoint or the method to request a release every 5 seconds.
You need to make sure to respond to this request with a status 404
in case the user is not to be released just yet (payment and processing on your side are not complete yet)
or 200
if the payment has been completed and the processing on your side is done and the user can be released and forwarded withing your payment flow.
In case you want to redirect the user to the next step in your system the poll endpoint needs to respond with a body containing json like: { forward_to: 'https://example.com/next_step_url' }
.
It is not enough to rely on setting forward_to
initially with the tracking request, you will also need to respond with forward_to
when implementing polling
as the entire reason for polling is to cover cases where websockets fail and the initial forward_to
can not be communicated to the client.
connected
connected
A function that will be called once the user connects a wallet.
This function will be called with the connected wallet address as the main argument:
DePayWidgets.Payment({
connected: (address)=> {
// do something with the address
}
})
closed
closed
A function that will be called once the user closes the widget (no matter if before or after the payment).
DePayWidgets.Payment({
closed: ()=> {
// do something if user closed the widget
}
})
sent
sent
A function that will be called once the payment has been sent to the network (but still needs to be mined/confirmed).
The widget will call this function with a transaction as single argument (see: depay-web3-wallets for more details)
DePayWidgets.Payment({
sent: (transaction)=> {
// called when payment transaction has been sent to the network
}
})
confirmed
confirmed
A function that will be called once the payment has been confirmed once by the network.

DePayWidgets.Payment({
confirmed: (transaction)=> {
// called when payment transaction has been confirmed once by the network
}
})
failed
failed
A function that will be called if the payment execution failed on the blockchain (after it has been sent/submitted).
The widget will call this function passing a transaction as single argument (see: depay-web3-wallets for more details)

failed: (transaction)=> {
// called when payment transaction failed on the blockchain
// handled by the widget, no need to display anything
}
})
critical
critical
A function that will be called if the widget throws an critical internal error that it can't handle and display on it's own:

critical: (error)=> {
// render and display the error with error.toString()
}
})
error
error
A function that will be called if the widget throws an non-critical internal error that it can and will handle and display on it's own:
DePayWidgets.Payment({
error: (error)=> {
// maybe do some internal tracking with error.toString()
// no need to display anything as widget takes care of displaying the error
}
})
providers
Allows to set providers to be used for making RPC calls to the individiual blockchains:
DePayWidgets.Payment({
providers: {
ethereum: ['http://localhost:8545'],
bsc: ['http://localhost:8545']
}
})
currency
Allows you to enforce displayed local currency (instead of automatically detecting it):

}
})
event
event
If set to ifSwapped
, emits a payment event if payments are routed through router smart contract.
Payments are routed through the DePayPaymentRouter if swapping tokens is required in order to perform the payment. If payments are not routed through the router, e.g. direct transfer, no event is emited if event
is set to ifSwapped
.
DePayWidgets.Payment({
event: 'ifSwapped'
})
style
style
Allows you to change the style of the widget.
DePayWidgets.Payment({
style: {
colors: {
primary: '#ffd265',
text: '#e1b64a',
buttonText: '#000000',
icons: '#ffd265'
},
fontFamily: '"Cardo", serif !important',
css: `
@import url("https://fonts.googleapis.com/css2?family=Cardo:wght@400;700&display=swap");
.ReactDialogBackground {
background: rgba(0,0,0,0.8);
}
`
}
})

.ReactDialogBackground {
background: rgba(0,0,0,0.8);
}
`
}
})
unmount
unmount
Allows you to unmount (the React safe way) the entire widget from the outside:
let { unmount } = await DePayWidgets.Payment({})
unmount()
recover
recover
Allows you to recover a previous made payment. E.g. useful if you need to continue to show a pending payment progress if user rearrives or reloads a payment page:
DePayWidgets.Payment({
recover: {
blockchain: 'ethereum',
transaction: '0x081ae81229b2c7df586835e9e4c16aa89f8a15dc118fac31b7521477c53ed2a9',
sender: '0x317d875ca3b9f8d14f960486c0d1d1913be74e90',
nonce: 2865,
afterBlock: 14088130,
token: '0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE',
amount: 0.0001
}
})
A recovered payment still results in a confirmed or failed payment, and also calls one of those callbacks also when created with recover.
DePay Sales
DePay Sales allows you to sell tokens directly from your website or dApp with automatic any-to-any payment conversion (so people can use any token when buying your token directly off your website or dApp).
Preparation
In order to sell tokens in a decentralized way, that token needs to have a liquidity pool on a decentralized exchange:
Quick start
<script src="https://integrate.depay.fi/widgets/v6.js"/>
DePayWidgets.Sale({
sell: {
'ethereum': '0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb'
}
});
Configuration
You need to pass a configuration object to DePayWidgets.Sale
which needs to at least contain the sell
field:
DePayWidgets.Sale({
sell: {
'ethereum': '0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb'
}
});
You can also sell on multiple blockchains:
DePayWidgets.Sale({
sell: {
'ethereum': '0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb',
'bsc': '0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb'

// called when payment transaction failed on the blockchain
// handled by the widget, no need to display anything
}
});
critical

css: `
@import url("https://fonts.googleapis.com/css2?family=Cardo:wght@400;700&display=swap");
.ReactDialogBackground {
background: rgba(0,0,0,0.8);
}
`
}
});
unmount
unmount
Allows you to unmount (the React safe way) the entire widget from the outside:
let { unmount } = await DePayWidgets.Payment({})
unmount()
DePay Connect
DePay Connect allows you to have your users connect their crypto wallet to your dApp or website.
Returns connected account
, accounts
and wallet
in return.
<script src="https://integrate.depay.fi/widgets/v6.js"/>
let { account, accounts, wallet } = await DePayWidgets.Connect()
See depay-web3-wallets for more details about the returned wallet
.
Rejections
- Rejects if user just closes the dialog without connecting any wallet:
DePayWidgets.Connect().then(()=>{}).catch((error)=>{
error // "USER_CLOSED_DIALOG"
})
DePay Login
DePay Login allows you to perform web3 wallet logins with ease.
Returns account
if succesfully signed and recovered log in message.
<script src="https://integrate.depay.fi/widgets/v6.js"/>
let message = "Sign to login"
let account = await DePayWidgets.Login({ message })
Connects wallet and instructs connected wallet to sign message
, afterwards sends signature
and message
to POST /login
(or endpoint
if defined):
POST /login
BODY
{
"message": "Sign to login",
"signature": "0x123456" // raw signature
}
The /login
endpoint needs to recover the address for message
and signature
and needs to return it in the response:
POST /login
RESPONSE
"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
Which will resolve the DePayWidgets.Login
request to the resolved account:
account // 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
You can also pass a recover
function that takes care of signature recovery:
DePayWidgets.Login({ message, recover: ({ message, signature })=>{
return new Promise((resolve, reject)=>{
fetch('https://example.com/login', {
method: 'POST',
body: JSON.stringify({ message, signature })
})
.then((response)=>{
if(response.status == 200) {
response.text().then((account)=>{
resolve(account)
}).catch(reject)
} else {
response.text().then((text)=>{
reject(text || 'Recovering login signature failed!')
}).catch(reject)
}
})
})
}
})
Rejections
- Rejects if user just closes the dialog without connecting any wallet:
DePayWidgets.Login().then(()=>{}).catch((error)=>{
error // "USER_CLOSED_DIALOG"
})
DePay Select
DePay Select widget allows you to open a dialog that allows you to select things like tokens, etc.
Resolves with what has been selected by the user:
<script src="https://integrate.depay.fi/widgets/v6.js"/>
let token = await DePayWidgets.Select({ what: 'token' })
// token
// {
// address: "0xa0bed124a09ac2bd941b10349d8d224fe3c955eb"
// blockchain: "ethereum"
// decimals: 18
// logo: "https://raw.githubusercontent.com/trustwallet/assets/master/blockchains/ethereum/assets/0xa0bEd124a09ac2Bd941b10349d8d224fe3c955eb/logo.png"
// name: "DePay"
// symbol: "DEPAY"
// }
