Router

router

Description

This contract implements the router and does the management of the pools. Due to the distributed nature of the TON Blockchain router, it can't do many checks, so it's mostly the proxy for the calls. The router contract so far is used as an owner of all the wallets holding the funds invested by liquidity providers.

The main idea is that if malformed or corrupted data is sent to the router it would create a malformed address of the pool and the message sent to it would fail. So if the message reaches the pool it means some criteria are satisfied.
