Make multiple transactions on different blockchains These are the routes provided by our partners Li.Fi, Socket.Tech and Rango. In the first transaction, you do the swap and bridge, and in the second (and sometimes the third), you do the swap on the target chain. This solution is safe but highly inconvenient due to the need to stay on the site for a long time to make the second (third) transaction, while the rate has not changed much. If the rate changes a lot, the transaction on the target chain with the to_token_amount promised earlier will fail, and the user will lose money for gas and will remain with an intermediate token. It is also worth noting that these aggregators have a complex slippage logic, which does not guarantee the receipt of the requested number of tokens, but only indicates a conditional slippage of 3% to each protocol. This means that if the slippage in the first and second transaction is equal to 3%, the total slippage will amount to 6%.
