Transaction Params

The [buy] and [sell] sections control transaction parameters for each direction.

[buy]
slippage = 200
unit_limit = 160000
max_block_difference = 5
nonce_delay = 50
panic_slippage = 1000

[buy.dynamic_fee]
percentile = 7000
fee_multiplier = 1.0
fee_cap = 0

Fields

Field	Description
slippage	Slippage tolerance in bps (100 = 1%, 200 = 2%, 50 = 0.5%)
unit_limit	Compute unit limit. 160,000–300,000 is typical
max_block_difference	Transaction expiry in slots. Lower = less stale risk
nonce_delay	Nonce rotation interval in ms. See Nonce Pool
panic_slippage	Slippage for panic sell (- key) in bps. Default 1000 = 10%

Dynamic Fee

Field	Description
percentile	Fee percentile (×100). Example: 7000 = p70
fee_multiplier	Multiply the fee by this factor. 1.0 = as-is
fee_cap	Max fee in microlamports. 0 = no cap

Example: Aggressive Sells

[sell]
slippage = 500
unit_limit = 160000
max_block_difference = 5
nonce_delay = 50
panic_slippage = 1500

[sell.dynamic_fee]
percentile = 9000
fee_multiplier = 1.5
fee_cap = 0

Higher percentile and multiplier to prioritize landing sells quickly. Panic slippage at 1500 bps (15%) for emergency exits.
