Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client provides a convenient way to interact with TON blockchain.

By default, it uses a single connection to a lite server. But internally, it makes use of a failover pool, so it is possible to force it to use multiple connections. Take a look at WithMaxConnectionsNumber() option.

When the client is configured with several connections, two different lite servers can be used for two consequent requests. Because a blockchain is inherently a distributed system, this could lead to some inconsistencies. For example, 1. you obtain a master head with GetMasterchainInfo, 2. you get an account state with GetAccountState, the account state can be obtained from a block that is earlier in the blockchain than the master head you obtained at step 1. To avoid this, you can use WithBlock() method to specify a target block for all requests.
