The @stacks/connect library for web apps on Stacks: it opens a wallet selector (Leather, Xverse, Asigna, Fordefi, plus WalletConnect), keeps the session, and asks the wallet to sign and broadcast STX transfers and contract calls. Works with React, Vue or plain JS. Free and MIT. Stacks Labs' own support table shows some methods still unimplemented and differences in how wallets handle Bitcoin PSBT signing, so test with each wallet you plan to support.

Catch Stacks only; wallets differ on some methods, so test each one you support

Chain support, with sources

We only add a chain when the maker's own docs name it. "EVM-compatible" alone counts for no specific chain. A testnet-only record means the page we checked only shows testnet; it isn't a finding that mainnet is unsupported. This is what the docs say, not a test or security review.
