LocalCoinSwap will be releasing crypto-to-crypto trading in 2 stages:
Stage 1 will be implemented soon and will consist of one cryptocurrency being transacted on the platform, and the other being transacted off the platform. This will work in a similar fashion to Crypto to fiat trading. The on-platform currency will be held in escrow while the other currency is transacted directly from the buyer to the seller, off the platform. Given the distributed ledger technology of blockchain, this will be perfectly safe for users as dispute resolution staff will have access to transaction data of the off-platform Crypto.
Stage 2 will be a future implementation and will consist of both currencies being exchanged on the LocalCoinSwap exchange.
