Tools to simplify the deployment and interaction with the wallet smart contract

This library supports:

  1. Address generation from public or private keys for V1-V4 wallets
  2. Message generation for deploying new wallets
  3. Message generation for TON transfer (long comment supported) and custom payload (for V1-V4 supports up to 4 payload messages)

Functions

func GenerateStateInit added in v1.2.1 

func GenerateStateInit(
	key ed25519.PublicKey,

GenerateWalletAddress Generate wallet address from known workchain, public key and version. subWalletId is only used in V3 and V4 wallets. Use nil for default value. The version number is associated with a specific implementation of the wallet code (https://github.com/toncenter/tonweb/blob/master/src/contract/wallet/WalletSources.md)
