# SigVerify
[](https://pkg.go.dev/github.com/storyicon/sigverify?tab=doc)
[](https://goreportcard.com/report/github.com/storyicon/sigverify)
This project is used to verify signatures under various specifications of ethereum. In addition to the standard elliptic curve signature, it also supports the signature of wallets such as ledger and argent.
It supports:
1. Standard elliptic curve signature verification. (eth_sign).
2. [EIP712](https://eips.ethereum.org/EIPS/eip-712) typed data verification. (eth_signTypedData_v*).
3. [ERC1271](https://eips.ethereum.org/EIPS/eip-1271) Smart contract wallet signature verification (isValidSignature).
4. Some hardware wallets signature verification such as `ledger`.
## Examples
### 1. Standard elliptic curve signature verification
```cgo
package main
import (
"fmt"
ethcommon "github.com/ethereum/go-ethereum/common"
"github.com/storyicon/sigverify"
)
func main() {
valid, err := sigverify.VerifyEllipticCurveHexSignatureEx(
ethcommon.HexToAddress("0xb052C02346F80cF6ae4DF52c10FABD3e0aD24d81"),
[]byte("hello"),
"0x0498c6564863c78e663848b963fde1ea1d860d5d882d2abdb707d1e9179ff80630a4a71705da534a562c08cb64a546c6132de26eb77a44f086832cbc1dbe01f71b",
)
fmt.Println(valid, err) // true
}
```
### 2. EIP-712 Typed data verification
```cgo
package main
import (
"encoding/json"
"fmt"
ethcommon "github.com/ethereum/go-ethereum/common"
"github.com/ethereum/go-ethereum/signer/core/apitypes"
"github.com/storyicon/sigverify"
)
const ExampleTypedData = `
{
"types": {
"EIP712Domain": [
{
"name": "name",
"type": "string"
},
{
"name": "chainId",
"type": "uint256"
}
],
"RandomAmbireTypeStruct": [
{
"name": "identity",
"type": "address"
},
{
"name": "rewards",
"type": "uint256"
}
]
},
"domain": {
"name": "Ambire Typed test message",
"chainId": "1"
},

"message": {
"identity": "0x0000000000000000000000000000000000000000",
"rewards": 0
}
}
`
func main() {
var typedData apitypes.TypedData
if err := json.Unmarshal([]byte(ExampleTypedData), &typedData); err != nil {
panic(err)
}
valid, err := sigverify.VerifyTypedDataHexSignatureEx(
ethcommon.HexToAddress("0xaC39b311DCEb2A4b2f5d8461c1cdaF756F4F7Ae9"),
typedData,
"0xee0d9f9e63fa7183bea2ca2e614cf539464a4c120c8dfc1d5ccc367f242a2c5939d7f59ec2ab413b8a9047de5de2f1e5e97da4eba2ef0d6a89136464f992dae11c",
)
fmt.Println(valid, err) // true
}
```
### 3. EIP1271 Smart contract wallet signature verification
```cgo
package main
import (
"context"
"fmt"
ethcommon "github.com/ethereum/go-ethereum/common"
"github.com/ethereum/go-ethereum/ethclient"
"github.com/storyicon/sigverify"
)
func main() {
client, err := ethclient.Dial("https://polygon-rpc.com")
if err != nil {
panic(err)
}
valid, err := sigverify.VerifyERC1271HexSignature(
context.Background(),
client,
ethcommon.HexToAddress("0x4836A472ab1dd406ECb8D0F933A985541ee3921f"),
[]byte{120, 113, 119},
"0xc0f8db6019888d87a0afc1299e81ef45d3abce64f63072c8d7a6ef00f5f82c1522958ff110afa98b8c0d23b558376db1d2fbab4944e708f8bf6dc7b977ee07201b00",
)
fmt.Println(valid, err) // true
}
```
