filecoin-sdk

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

Installation

go get

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

go get -u github.com/724165435/go-wallet-sdk/coins/filecoin

Usage

New Address

	privateKeyHex := "0x7c6207c56b6aa5ed4345c5f662816408e273cbdf64e2f01d54ced0125d6172c2"
	address, err := GetAddressByPrivateKey(privateKeyHex, MainnetPrefix)
	if err != nil {
		// todo
	}

Transfer

	from := "f1bh3d2y6xxugpg3ygzxnjhcrs5ffxh5nvqmanbia"
	to := "f1fvs2fjqr6ozk477zkwzvermhledmfkswt34cmhi"
	nonce := 0
	value := big.NewInt(20000000000000000)
	gasLimit := 210000
	gasFeeCap := big.NewInt(9455791480)
	gasPremium := big.NewInt(120242)
	method := 0
	message := NewTx(from, to, nonce, method, gasLimit, value, gasFeeCap, gasPremium)
	privateKeyHex := "0x7c6207c56b6aa5ed4345c5f662816408e273cbdf64e2f01d54ced0125d6172c2"
	tx, err := SignTx(message, privateKeyHex)
	if err != nil {
		// todo
	}
    hash, err := CalTxHash(tx)
    if err != nil {
        // todo
    }
