Problem

TON DEXes have fragmented liquidity, each with its own set of liquid tokens. As the TON ecosystem grows, this uneven distribution worsens, leading to inefficient trades and arbitrage opportunities. Users often lose money due to the high price impact when swapping tokens on a single DEX.

Solution

Rainbow Swap aggregates liquidity from multiple TON DEXes, distributing trade volume across optimal routes to minimize price impact and slippage. This ensures users get the best possible prices in a single transaction.

Examples

Smart contract

Rainbow routing wallet smart contract acts as a middleman, enabling seamless swaps between two different decentralized exchanges (DEXes) in a single transaction.
To guard against asset loss (there have been no such cases yet), it also allows users to withdraw GRAM or jettons, similar to a Jetton Wallet contract.

Smart contracts are written using FunC.
All code can be found in the contracts folder.
