For genuinely obscure tokens, the choice is often LetsExchange or a centralised exchange listing that does not exist. Its catalogue runs into the thousands across most chains, with both fixed and floating rates and fiat purchase routes through partners.
Pricing behaviour
The margin is embedded and variable. On liquid pairs it is competitive, in the 0.5% range. On thin assets it widens substantially — over 1%, sometimes considerably more — because the service must itself source liquidity in a market where that is expensive. That is economically rational and completely undisclosed, which is the problem: the interface presents both cases identically.
Reliability
Settlement on standard swaps is prompt and the flow is clean. The service applies the same screening as its peers, with the same consequences for flagged deposits. Complaint volume is moderate — below Changelly, above Exolix.
How to use it sensibly
Always compare the quote to the market price of both assets before sending. For a thin token that may require checking a DEX pool or an aggregator, which is more work than the service's convenience implies. If the implied cost exceeds a couple of per cent, consider routing on-chain instead, where you can see the pool depth you are trading against.
Who should use LetsExchange
Users who need an asset the better-priced services do not support, having first checked what the swap actually costs. For mainstream pairs there is no reason to use it over FixedFloat, SideShift or Exolix.
