# Solana library for Go
|
||||
|
||||
Go library to interface with Solana nodes's JSON-RPC interface, Solana's SPL tokens and the
|
||||
[https://dex.projectserum.com](Serum DEX) instructions. More contracts to come.
|
||||
|
||||
# Usage
|
||||
|
||||
```go
|
||||
solana.NewClient("https://mainnet.solana.dfuse.io")
|
||||
|
||||
```
|
||||
|
||||
