pysolana 0.1.6

Python Solana Package

PySolana

PySolana is a Python library for dealing with Solana blockchain.

Installation

Use the package manager pip to install pysolana.

pip install pysolana

Usage

There are 2 modules in pysolana:

• api.py includes all RPC API Solana methods.
• sol.py includes class Sol that used to simply manage Solana accounts with Python3

api.py

You can see all RPC API Solana methods here

Example:

print(getTransactionCount()) # 555309062

sol.py

Keypairs

To generate new keypair you need to create Sol object in code.

keypair = Sol(chain='devnet')
print(keypair.seedphrase) # 12-words seedphrase that used to import keypair
print(keypair.pubkey) # Solana account address

To import keypair put seedphrase in __init__ method.

kp1 = Sol(chain='devnet')
kp2 = Sol(seedphrase=kp1.seedphrase, chain='testnet')
print(kp1.pubkey == kp2.pubkey) # True

One keypair can be used in different chains.

There are some methods in Sol class:

• set_chain
• balance
• airdrop
• transfer

set_chain

set_chain(chain) method used to change keypair chain.

kp = Sol(chain='mainnet') # Created keypair

kp.balance() # Check balance in mainnet
kp.set_chain('testnet') # Set chain to testnet
kp.balance() # Check balance in testnet

balance

balance() method used to get balance of account.

kp = Sol(seedphrase=my_seedphrase, chain='mainnet') # Created keypair

print(kp.balance()) # 15.0

airdrop

aidrop(amount, wait=True) method used to request airdrop of SOL tokens in devnet.

kp = Sol(chain='devnet') # Created keypair

print(kp.balance()) # 0.0
kp.airdrop(100) # Request airdrop to account in devnet.
print(kp.balance()) # 100.0

kp.airdrop(100, wait=False)
# Here I can do anything without waiting transaction to confirm
print(kp.balance()) # 100.0
# Transaction is not confirmed in chain and balance() showing only confirmed balance.

transfer

transfer(to, amount, wait=True) method used to send SOL tokens to another account.

kp1 = Sol(chain='devnet') # Created first keypair
kp2 = Sol(chain='devnet') # Created second keypair

kp1.airdrop(100)
kp2.airdrop(100)

print(kp1.balance()) # 100.0
print(kp2.balance()) # 100.0

kp1.transfer(kp2, 10) # 'to' can be Sol object or str pubkey

print(kp1.balance()) # 89.999995
print(kp2.balance()) # 110.0

kp2.transfer(kp1.pubkey, 10)

print(kp1.balance()) # 99.999995
print(kp2.balance()) # 99.999995

kp1.transfer(kp2, 50, wait=False)
# Here I can do anything without waiting transaction to confirm
print(kp1.balance()) # 99.999995
print(kp2.balance()) # 99.999995
# Transaction is not confirmed in chain and balance() showing only confirmed balance.
