There is no in-built DEX on the Symbol blockchain, so I designed a manual swap method for Baadbe and Symbol tokens.
"Exchange rate : 1XYM = 10900 BAADBE.COM, service fee 100 BAADBE, minimum amount is 10XYM, Send your XYM to ND2JHIVPGD3KXP5LEINOEY6YHPSNCQMMDQUE7NA to swap for BAADBE.COM Mosaic, or Vice versa , with a comment is better. The new exchange rate will replace the old one. This is manual service by me Okchai or my team, normally the transaction will be done within 24 hours. For contacts information, please visit https://baadbe.com "
