there's a canary strat at https://github.com/rainlanguage/rain.dex.pubstrats/blob/main/src/infra/canary.rain

basically it sets a non-zero amount with a 0 io ratio

this means that the strat just gives money to the bot unconditionally

there's a timer on the ensure so it doesn't insta-drain itself

this can be used to check that the bot clears, e.g. after making changes or bringing up a new bot etc. to make sure that the infra is working correctly

we should document that and use it, as it should work on any/every network

Edit

• what it does and purpose
  canary is a simple order that sets a non-zero amount with a 0 io ratio, this means that the strat just gives money to the bot unconditionally, there's a timer on the ensure so it doesn't insta-drain itself, this can be used to check that the bot clears, e.g. after making changes or bringing up a new bot etc. to make sure that the infra is working correctly.
• where to find the strat

• anything extra to set up
  canary orders are like any other orders, but they clear every hour (or whatever cooldown period is set for it) so if they happen to not clear for any reason the exec kpi alert will go off if that happens a few times in an hour,
  the exec kpi checks the unsuccessful transactions, and as its clears when there are many failed transactions in a row in a short timespan, that indictaes something is probably not right and needs attention. besides these there is nothing special about canaries, now that bot has self fudning owned vaults option, one can specify the canary vault in the bot's env vars and bot will redeposit into the specified vault once the it goes below the specified threshold, this is not specific to canaries, but any vault can be set to be refunded. for more info about this, check bot's README, but can simply set self fund vaults by follwoing example:

SELF_FUND_ORDERS=token,vaultId,threshold,toptupamount;token,vaultId,threshold,toptupamount
