Platform specific packaging

In case you want to use and package only specific platforms, use platform-specific packages:

EVM specific packaging

import { getWallets } from '@depay/web3-wallets-evm'

SOLANA specific packaging

import { getWallets } from '@depay/web3-wallets-solana'

Functionalities

getWallets

getWallets: Returns an array of available/connectable wallets. Can wait up to 5 seconds because of checking existing WalletConnect connections. Use drip to receive available wallets faster.

let availableWallets = await getWallets();
// [<Wallet name='MetaMask'>, <Wallet name='Phantom'>]

let availableWallets = await getWallets();
// [] no wallets detected. (you can still try have user connec via WalletConnect or WalletLink)

import { getWallets, wallets } from "@depay/web3-wallets"

let availableWallets = await getWallets()

let wallet
if(availableWallets.length == 1) {
  wallet = availableWallets[0]
} else if(availableWallets.length > 1) {
  wallet = availableWallets[parseInt(prompt('Which wallet do you want to connect?'), 10)]
} else {
  // Let the user choose:
  // you can still try to connect via wallets.WalletConnect.connect()
  // or wallets.WalletLink.connect()
  wallet = wallets.WalletLink
}

drip

Pass a drip callback to getWallets to receive available wallet as soon as they are found, without waiting for all wallets to be checked:

getWallets({
  drip: (wallet)=>{
    setAvailableWallets(
      availableWallets.concat([wallet])
    )
  }
})

Name

name:string: Returns the name of the wallet.

wallet.name // 'MetaMask'

Logo

logo:string: Returns the logo of the wallet as PNG base64-encoded.

wallet.logo // 'data:image/png;base64,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'

await wallet.connectedTo('ethereum') // true

If no param is given it well tell you to which blockchain the wallet is connected to:

await wallet.connectedTo() // 'bsc'

can provide an array if connected to multiple blockchains:

await wallet.connectedTo() // ['ethereum', 'bsc']

Receive wallet events

on(string, function):undefined: Register a callback function for given events.

wallet.on('account', (newAccount)=>{
  doSomething(newAccount)
})

Events

on('account', (newAccount)=>{}): Triggers when user changes the connected/active wallet account.

Deregister wallet events

.on returns a callback function that needs to be passed to .off if you want to deregister the event listener:

let callback = wallet.on('account', (newAccount)=>{
  doSomething(newAccount)
})

//...

wallet.off('account', callback) // removes listener

Switch blockchain/network

async switchTo(blockchain): Changes wallet connection to a specific network (adds it to the wallet in case it's missing)

await wallet.switchTo('bsc')

Solana: Sign and send instructions

instructions Array: A set of TransactionInstructions

e.g. Send 1 USDC:

import Token from '@depay/web3-tokens'

let sentTransaction = await wallet.sendTransaction({
  blockchain: 'solana',
  instructions: [
    await Token.solana.createTransferInstructions({
      token: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v', 
      amount: '1000000',
      from: await wallet.account(),
      to: '5AcFMJZkXo14r3Hj99iYd1HScPiM4hAcLZf552DfZkxas'
    })
  ],
  sent: function(transaction){},
  succeeded: function(transaction){},
  failed: function(transaction, error){}
})

Solana: Instruction signers

If you need to sign an instruction (e.g. creating "throw away" accounts)

you can pass signers as part of the transaction passed to sendTransaction:

import { getProvider } from '@depay/web3-client'
import Token from '@depay/web3-tokens'
import { PublicKey, SystemProgram, Keypair } from '@depay/solana-web3.js'

const wallets = await getWallets()
const wallet = wallets[0]
const fromAddress = await wallet.account()
const provider = await getProvider('solana')
const keypair = Keypair.generate()
const account = keypair.publicKey.toString()
const rent = await provider.getMinimumBalanceForRentExemption(Token.solana.TOKEN_LAYOUT.span)

let instruction = SystemProgram.createAccount({
  fromPubkey: new SolanaWeb3js.PublicKey(fromAddress),
  newAccountPubkey: new SolanaWeb3js.PublicKey(wrappedAccount),
  programId: new SolanaWeb3js.PublicKey(Web3Tokens.Token.solana.TOKEN_PROGRAM),
  space: Web3Tokens.Token.solana.TOKEN_LAYOUT.span,
  lamports: rent
})

let sentTransaction = await wallet.sendTransaction({
  blockchain: 'solana',
  instructions: [instruction],
  signers: [keypair],
  sent: function(transaction){},
  succeeded: function(transaction){},
  failed: function(transaction, error){}
})

Solana: Address Lookup Tables

If you need to pass address lookup tables in order to reduce transaction size,

you can pass alts as part of the transaction passed to sendTransaction:

import { getProvider } from '@depay/web3-client'
import Token from '@depay/web3-tokens'
import { PublicKey, SystemProgram, Keypair } from '@depay/solana-web3.js'

const wallets = await getWallets()
const wallet = wallets[0]
const fromAddress = await wallet.account()
const provider = await getProvider('solana')
const keypair = Keypair.generate()
const account = keypair.publicKey.toString()
const rent = await provider.getMinimumBalanceForRentExemption(Token.solana.TOKEN_LAYOUT.span)

let instruction = SystemProgram.createAccount({
  fromPubkey: new SolanaWeb3js.PublicKey(fromAddress),
  newAccountPubkey: new SolanaWeb3js.PublicKey(wrappedAccount),
  programId: new SolanaWeb3js.PublicKey(Web3Tokens.Token.solana.TOKEN_PROGRAM),
  space: Web3Tokens.Token.solana.TOKEN_LAYOUT.span,
  lamports: rent
})

let sentTransaction = await wallet.sendTransaction({
  blockchain: 'solana',
  instructions: [instruction],
  signers: [keypair],
  alts: ['3sEm5YYxgLnP1Z11WXHSgScWqFMrATSNDgZcXAcB1w9A'],
  sent: function(transaction){},
  succeeded: function(transaction){},
  failed: function(transaction, error){}
})

value

If value is passed as a number it's gonna be converted into a big number applying the individual blockchain's default decimals:

let transaction = new Transaction({
  ...,
  value: 1
})

transaction.value // '1000000000000000000'

If value is passed as a string or as a BigNumber, value is used just as provided:

let transaction = new Transaction({
  ...,
  value: '1000000000000000000'
})

transaction.value // '1000000000000000000'

wrong network

sendTransaction rejects with:

{ code: 'WRONG_NETWORK' }

in case wallet is connected to the wrong network and network cant be switched automatically.

Get wallet transaction count

import { transactionCount } from '@depay/web3-wallets'

let count = await transactionCount({ blockchain: 'polygon', address: '0x8Ffdb4Ee24a625856c82db7FAAE5Bd8B3406eF86' })

Sign messages

let signature = await wallet.sign("This is a message to be signed")
