Making AI agents safe enough to move money.

AI agents can already move money, but nothing checks if a transaction matches what you actually asked for. ClearSign reads every transaction and explains it in plain language before it gets signed. If something breaks your rules, it gets blocked. Live on Solana mainnet.

Two-factor codes that never touch a server.

Every popular authenticator asks you to trust someone's cloud with the keys to your accounts. Fidel keeps your 2FA secrets on your device, encrypted, and syncs them between your devices directly. The right amount of infrastructure for 2FA is zero.

Crypto trading that fits in your pocket.

Most trading apps assume a desktop and a power user. Shuffles routes trades across seven networks behind one interface, so you can find a token, swap it, and settle with one hand on your phone.

Prompts were the app layer. Context is turning into the platform layer, and it is starting to look like a database problem. Why context management will separate AI products as models become interchangeable.

For two years everyone asked which model is smartest. The real question is becoming who remembers you best, and that is much harder to switch away from.

It is not a design choice. It is account locking, compute limits, and the transaction model. Why AMMs win on Solana and how perps actually work.

Solana's transaction pipeline was built to be fast, not predictable. The new execution stack is changing which of those wins.
