# Supported Blockchains and APIs
The availability of wallets endpoints varies by blockchain.
The following tables are organized by API category and list which endpoints are
supported on each blockchain for both mainnet and testnet.
## Developer-controlled wallets
The following tables group developer-controlled wallets endpoints by API
category and show which blockchains support them.
### Wallets API
Select the tab that matches the first letter range of your blockchain name to
see supported wallet endpoints.

### Signing API
Select the tab that matches the first letter range of your blockchain name to
see supported signing endpoints.
To sign transactions with an `EVM-TESTNET` wallet, use the appropriate
[chain ID](/w3s/sign-tx-chain-id). If you're on mainnet, you can use an `EVM`
wallet to sign transactions on any EVM-compatible chain.
