### TokenPocket supports qrcode protocol as follows:
* Receipt qrcode
* Create Eos Account qrcode
* Import BTC watch-wallet qrcode
* DApp login qrcode
* DApp call wallet to transfer tokens qrcode
* DApp call wallet to sign tx qrcode
* DApp call wallet to sign message qrcode
* WalletConnect
* Add DApp to Favorites qrcode
* Open DApp qrcode
### Receipt qrcode
The EVM network support two kinds of receipt qrcode
```
0xbc4ca0eda7647a8ab7c1161c2e118a18a936f13d
```
```
ethereum:0x4122131cd452e9729546b79f9f4e00c12e1d1c22
```
The EOSIO network support two kinds of receipt qrcode
```
//account
xiao1111aaaa
```
```
// ScanProtocol
{
"address": "xiaoyuantest", //receiver account
"amount": "0",
"symbol": "EOS",
"contract": "eosio.token"，
"precision": 4,
"protocol": "ScanProtocol",
"blockchain": "EOS",
"action": "transfer"
}
```
BTC, TRON, Cosmos, SOL,IOST,Polkadot, use address or account(IOST) to generate receipt qrcode
### Create Eos Account
The qrcode is used to create Eos account
```
{
"account": "pubyeoaad33k", //the account to be created
//owner to the new account
"owner": "EOS7eZbMjyMxtp35sg6xHcqtEHzEYb7ahzdHRAGcYgcJW8k8V8PnS",
//active to the new account
"active": "EOS7eZbMjyMxtp35sg6xHcqtEHzEYb7ahzdHRAGcYgcJW8k8V8PnS",
"blockchain": "EOS", //network
"action": "createAccount"
}
```
### Import BTC wallet-wallet
```
{
"action": "watchWallet",
"data": [{

}]
}
```
### Watch-wallet and Cold-wallet

### EVM
watch-wallet qrcode. This qrcode is used to scan by cold-wallet to sign
