This is a scam and whatever application they’re running has no real integration with Bitcoin. The tweet says they wrote uniswap’s bytecode to the Bitcoin blockchain as an inscription, as if that would mean anything on Bitcoin… If that’s not a red flag then I don’t know what is.

If you need any more assurances it’s a scam, after digging through their websites (trustless.market, trustlessfaucet.io, and trustless.computer) I was able to find their Github organization (https://github.com/trustlesscomputer) and took a look through their “tc-sdk” (https://github.com/TrustlessComputer/tc-sdk)

Just take a look here: https://github.com/TrustlessComputer/tc-sdk/blob/master/src/wallet/call.ts#L22

Their wallet sdk “signs” a transaction by making a web request to “trustlesswallet.io” with query parameter “function” that’s set to the value “sign”.

Don’t even get me started on their “bitcoin” folder which is just a clone of https://github.com/generative-xyz/generative-sdk/tree/main/src/bitcoin
