Onchain program
Last updated
Last updated
The onchain program takes in mints and pools, and will calculate the most optimal arbitrage trade between them and execute the trades.
If you want maximum flexibility, you can write your own bot and just call the onchain program from there. This allow you to do whatever customization you want but still utilize the onchain program to get maximum arb opportunity.
Demo bot:
Current supported DEX:
Raydium
Raydium CPMM
Raydium CLMM
Pumpfun Swap
Meteora DLMM
Meteora Dynamic Pool
Orca whirlpool
NOTE: It's recommended to include this address lookup table as it has all the fixed keys needed: 4sKLJ1Qoudh8PJyqBeuKocYdsZvxTcRShUt9aKqwhgvC
NOTE: max_bin_to_process is how many bins the program can look through when calculating optimal trade size. Each bin lookup will take ~10k compute units. So you should setup your compute unit limit accordingly. For example, I usually use 650_000 compute unit limit with max_bin_to_process = 30. Bot uses the following code to calculate this number:
let bins = ((config.bot.compute_unit_limit - 300_000 - if enable_kamino { 80_000 } else { 0 })
/ 10_000) as u64;Here's a simplified Rust example for how to interact with the program. You can include multiple X mints with their according pools here.
You can also check to see how to extract all the keys for each pool type.
