I couldn't find anywhere that had clear examples of WebCryptoAPI, so I wrote examples and made a live table with them. Pull requests welcome!

| <title>WalletConnect Example</title> |
WalletConnect Instant feature introduces the ability to make an ephemeral session that bypasses the process of session approval by the wallet, displaying to the user a call request to be signed from the Dapp right after scanning the QR Code. This is useful for one-time use-cases like payments, topping-up or withdrawals. This is still highly experimental and hasn't been published to the official library. A PoC to aggregate feedback on this feature!
Source code available at WalletConnect/walletconnect-monorepo on walletconnect-instant branch.

| // yet while Kotlin is the minority, it's preferable to increase integers than decrease them | |
| // this way we can keep backwards-compatibility for Kotlin clients in older releases | |
