Trio can sign for any chain whose signature scheme it supports: ECDSA (EVM chains and Bitcoin legacy), EdDSA (Solana and other non-EVM chains), and Taproot (Bitcoin P2TR / Taproot addresses). Because Trio produces a signature over a transaction hash and nothing more, any chain that uses one of these schemes works; your app builds and broadcasts the transaction.
Reading the tables
The tables below list the chains we have verified, grouped by the scheme Trio uses to sign for them. Find your chain to confirm it is covered and see which scheme it uses; that tells you which SDK support to check on Supported Features.
If your chain is not listed but uses ECDSA, EdDSA, or Taproot, it will still work; the tables are a verified subset, not a hard limit. For a chain or scheme not covered here, contact us.
