For the full walkthrough, see Solana: Creating a trading and sniping pump.fun bot.
For near-instantaneous transaction propagation, you can use the Chainstack Solana Trader nodes.
Make sure you have the required packages installed pip install -r requirements.txt.
Make sure you have your endpoints set up in config.py.
Quick note on a couple on a few new scripts in /learning-examples:
(this is basically a changelog now)
Bonding curve state check
check_boding_curve_status.py — checks the state of the bonding curve associated with a token. When the bonding curve state is completed, the token is migrated to Raydium.
To run:
python check_boding_curve_status.py TOKEN_ADDRESS
Listening to the Raydium migration
When the bonding curve state completes, the liquidity and the token graduate to Raydium.
listen_to_raydium_migration.py — listens to the migration events of the tokens from pump_fun to Raydium and prints the signature of the migration, the token address, and the liquidity pool address on Raydium.
Note that it's using the blockSubscribe method that not all providers support, but Chainstack does and I (although obviously biased) found it pretty reliable.
To run:
python listen_to_raydium_migration.py
The new two additions are based on this question associatedBondingCurve #26
You can take the compute the associatedBondingCurve address following the Solana docs PDA description logic. Take the following as input as seed (order seems to matter):
- bondingCurve address
- the Solana system token program address:
TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA - the token mint address
And compute against the Solana system associated token account program address: ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL.
The implications of this are kinda huge:
- you can now use
logsSubscribeto snipe the tokens and you are not limited to theblockSubscribemethod - see which one is faster
- not every provider supports
blockSubscribeon lower tier plans or at all, but everyone supportslogsSubscribe
The following script showcase the implementation.
Compute associated bonding curve
compute_associated_bonding_curve.py — computes the associated bonding curve for a given token.
To run:
python compute_associated_bonding_curve.py and then enter the token mint address.
Listen to new direct full details
listen_new_direct_full_details.py — listens to the new direct full details events and prints the signature, the token address, and the bonding curve address.
To run:
python listen_new_direct_full_details.py
So now you can run listen_create_from_blocksubscribe.py and listen_new_direct_full_details.py at the same time and see which one is faster.
