Lightswap is live on TestFlight. 🚀Lightswap is live on TestFlight. 🚀
Some of you might remember me. About five months ago I posted here every day for 21 days, building Lightswap in public. Wins, missteps, designs scrapped, designs kept. All of it.
Then I went quiet.
I went quiet because I was building the thing.
And now it's real. Lightswap is on Apple TestFlight. You can download it right now.
iOS only for now. Android is coming at the end of this month.
What is Lightswap?
You've probably got bitcoin across multiple wallets, and maybe even use an exchange for buying or selling. Managing all of it means juggling apps, copy-pasting addresses, and context-switching constantly.
Lightswap connects all of it into one chat. You type what you want to do in plain English and it happens.
"Send 0.01 BTC to bc1q..."
"Buy $200 of bitcoin on Kraken"
"What's my balance on Coinbase?"
"When funds arrive at Kraken, sell them and send the cash to my bank account"
Built-in self-custody wallet.
Non-custodial.
Private Keys and API keys stay on your device.
Nothing moves without your confirmation. Later on you'll be able to add your bank accounts and brokerage accounts too.
I'd love feedback from this community. You guys don't sugarcoat things and that's exactly what we need.

give your account read/write prilvileges to AI, what could go wrong
An AI agent with API keys to all my crypto? No, thank you. Why is "swap" in the name?
Hey @SwapMarket, to be clear, the AI never has your keys. They're stored in your iPhone's Keychain (hardware-encrypted, never leaves your device).
The architecture is simple: the AI figures out what you want to do ("buy 0.1 BTC on Kraken"), e.g. your intent, then your phone executes it locally using keys only it has access to using traditional programming techniques not AI involved. Every trade requires your explicit confirmation with Face ID.
On the name: "swap" because one of the core actions is exchanging one asset for another - fiat to bitcoin, bitcoin to fiat, moving between accounts. "Light" because we're trying to make it feel effortless. Plus it's a fun name.
AI does have access to my API keys and can hallucinate. It takes me less time to actually do what I want by tapping the buttons then by typing the instruction in the chat box. Sorry, but I personally stay away from any and all AI agents on my phone or PC...
And here's a preview:

If Lightswap delivers on the promise of a clean natural language interface that executes across these platforms it could genuinely save people time and reduce friction.
From a product standpoint the key challenge will be trust. Users need absolute confidence that every action will only happen with explicit confirmation and that their keys and credentials are truly secure. The fact you are keeping everything on device is a strong starting point but it will be important to educate users on exactly how that works and to be transparent about any limitations.
Another factor to watch will be the integration depth. Surface level interactions are helpful but if you can build robust integration that supports edge cases and more complex workflows that will be the differentiator. In crypto people often run into nuanced scenarios with timing fees and liquidity constraints so being able to handle those without breaking the flow will make Lightswap more than just a convenience tool.
You should also anticipate that some users will want auditability. Having clear logs of every command executed and every movement of funds will go a long way in gaining adoption especially among those who manage significant amounts.
