Frequently asked questions
What chains are supported?
The skill supports sol, bsc, base, eth, and robinhood.
How do I handle rate limits?
If a request returns 429, check the X-RateLimit-Reset header or the reset_at field in the response body. Do not loop or auto-submit swap attempts; wait until the reset time and ask for user confirmation before retrying.
Is anti-MEV protection available on all chains?
No, anti-MEV protection is supported on sol, bsc, and eth, but it is not supported on the base chain.
What is the difference between --amount and --percent?
--amount specifies an exact input quantity in the token's smallest unit. --percent sells a percentage of the current balance and is only valid when the input token is not a currency (SOL/BNB/ETH/USDC).
