polkdot-sdk

Polkdot SDK is used to interact with the Polkdot blockchain, it contains various functions can be used to web3 wallet.

Installation

go get

To obtain the latest version, simply require the project using :

go get -u github.com/xiaohuasheng0x1/blockchains/coins/polkdot

Usage

New Address

	priKey, _ := hex.DecodeString("45d3bd794c5bc6ed91ae41c93c0baed679935703dfac72c48d27f8321b8d3a40")
	p := ed25519.NewKeyFromSeed(priKey)
	publicKey := p.Public().(ed25519.PublicKey)
	address, _ := PubKeyToAddress(publicKey, PolkadotPrefix)

Transfer

	tx := TxStruct{
		From:         "1GycBnSYfhVWN8yRxmLxJ6CXyyZEHgVJyiF8MWZDsKTLfhs",
		To:           "1GycBnSYfhVWN8yRxmLxJ6CXyyZEHgVJyiF8MWZDsKTLfhs",
		Amount:       10000000000,
		Nonce:        18,
		Tip:          0,
		BlockHeight:  10672081,
		BlockHash:    "0x569e9705bdcd3cf15edb1378433148d437f585a21ad0e2691f0d8c0083021580",
		GenesisHash:  "0x91b171bb158e2d3848fa23a9f1c25182fb8e20313b2c1eb49219da7a70ce90c3",
		SpecVersion:  9220,

		Version:      "84",
	}

	signed, err := SignTx(tx, Transfer, "45d3bd794c5bc6ed91ae41c93c0baed679935703dfac72c48d27f8321b8d3a40")
	if err != nil {
