Overview
Strica is a software company that builds tools for exploring and using the Cardano blockchain. It makes Cardanoscan, a block explorer where anyone can look up a transaction, a wallet address, or a stake pool, and Typhon Wallet, a browser wallet for holding and sending ADA. Strica also publishes the code behind both products as open-source libraries that other teams reuse.
Strica's work centers on Cardano, and part of it is funded through Project Catalyst, the network's community grant program. The company's JavaScript wallet library is used by Typhon Wallet, by Ledger Live, and by the Minswap exchange to build and sign Cardano transactions1. Strica did the development work on Ledger's Cardano support under a Catalyst proposal that Ledger itself submitted2.
Key Features
- One place to look up anything on Cardano. Cardanoscan covers transactions, addresses, stake pools, tokens, and governance votes3, with chart pages for network activity such as daily transaction counts and fees4.
- A wallet that never holds your keys. Strica states that Typhon Wallet gives it no access to recovery phrases or private keys, runs no tracking, and keeps no keys in the browser in its web version5.
- Send tokens without paying the extra ADA yourself. Warp Transactions let two Typhon Wallet users send each other a token other than ADA without the sender supplying the small amount of ADA that normally travels alongside it; the receiver's own funds cover that amount. Both people sign, and either can cancel6.
- Pay several people in one transaction. Typhon Wallet can send to many recipients at once and attach a note or reference number to the payment7.
- Code anyone can build on. Strica publishes typhon.js, the library that builds and signs the Cardano transactions inside Typhon Wallet, under the Apache 2.0 license, which lets anyone reuse it in their own products8.
What to Expect
Cardanoscan needs no account. Paste in a transaction ID or an address and you get its history, or open the chart pages to see how busy the network has been4. Typhon Wallet comes two ways: a browser extension for Chrome, Brave, and Edge, or a web version you open in a tab7. Hardware wallets from Ledger, Trezor, and Keystone pair with it7. Typhon Wallet also keeps your funds at a single address rather than spreading them across many, and converts imported wallets to that model, so balances and history stay in one view7.
Developers have more to work with. Cardanoscan offers access to its data through an API, a connection that lets other software pull the data automatically, and that service includes a free plan9. The project names and labels Cardanoscan shows for Cardano apps come from a public registry that anyone can add to with a pull request, the standard way to propose a change to shared code10. Strica also publishes the library that speaks a Cardano node's own network protocol directly, and both Cardanoscan and Typhon Wallet are built on it11.
