使用Golang验证Metamask以及WalletConnect签名

验证以太坊的椭圆曲线签名，以及EIP712、ERC1271（智能合约钱包）签名，支持 metamask、wallet connect（ledger、argent）等钱包。

它支持：

1. 标准椭圆曲线签名验证(eth_sign)。
2. EIP712 格式化数据验证（eth_signTypedData_v*）
3. ERC1271 智能合约钱包签名验证（isValidSignature）.
4. 一些硬件钱包的签名验证，例如ledger。

示例

1. 标准椭圆曲线签名

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 <nil>
}

2. EIP-712格式化数据签名

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"
    },
    "primaryType": "RandomAmbireTypeStruct",
    "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 <nil>
}

3. EIP1271智能合约钱包签名

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 <nil>
}
