Create offers
{
"min_seconds_between_offers": Add a random delay between creating offers between min and max, default 60.
"max_seconds_between_offers": ^, default "min_seconds_between_offers" * 4
"min_seconds_between_bids": Add a random delay between creating bids between min and max, default 60.
"max_seconds_between_bids": ^, default "min_seconds_between_bids" * 4
"wallet_port_override": Used for testing.
"prune_state_delay": Seconds between pruning old state data, set to 0 to disable pruning.
"main_loop_delay": Seconds between main loop iterations.
"prune_state_after_seconds": Seconds to keep old state data for.
"auth": Basicswap API auth string, e.g., "admin:password". Ignored if client auth is not enabled.
"offers": [
{
"name": Offer template name, eg "Offer 0", will be automatically renamed if not unique.
"coin_from": Coin you send.
"coin_to": Coin you receive.
"amount": Amount to create the offer for.
"minrate": Rate below which the offer won't drop.
"ratetweakpercent": modify the offer rate from the fetched value, can be negative.
"amount_variable": bool, bidder can set a different amount
"address": Address offer is sent from, default will generate a new address per offer.
"min_coin_from_amt": Won't generate offers if the wallet would drop below min_coin_from_amt.
"offer_valid_seconds": Seconds that the generated offers will be valid for.
"automation_strategy": Auto accept bids setting - "accept_all", "accept_known", or "none" (default: "accept_all")
"adjust_rates_based_on_market": Per-offer setting to adjust rates based on existing market offers (default: false)
"amount_step": REQUIRED - Offer size increment for privacy. Must be between 0.001 and "amount".
This prevents revealing exact wallet balance by creating stepped offers.
Example: 150 LTC balance, 100 LTC offer, 5 LTC increment, 76 LTC min balance = creates 70 LTC offer.
Without this, partial fills would reveal your exact remaining balance.
# Optional
"enabled": Set to false to ignore offer template.
"swap_type": Type of swap, defaults to "adaptor_sig"
"min_swap_amount": Sets "amt_bid_min" on the offer, minimum purchase quantity when offer amount is variable.
},
...
],
"bids": [
{
"name": Bid template name, must be unique, eg "Bid 0", will be automatically renamed if not unique.
"coin_from": Coin you receive.
"coin_to": Coin you send.
"amount": amount to bid.
"max_rate": Maximum rate for bids.
"min_coin_to_balance": Won't send bids if wallet amount of "coin_to" would drop below.
"offers_to_bid_on": Which offers to bid on - "all", "auto_accept_only", or "known_only" (default: "all")
# Optional
"enabled": Set to false to ignore bid template.
"max_concurrent": Maximum number of bids to have active at once, default 1.
"amount_variable": Can send bids below the set "amount" where possible if true.
"max_coin_from_balance": Won't send bids if wallet amount of "coin_from" would be above.
"address": Address offer is sent from, default will generate a new address per bid.
"use_balance_bidding": If true, calculates bid amount as (wallet_balance - offer_min_amount) instead of using template amount.
