The availability of Wallets products and endpoints varies by blockchain. Whichever infrastructure model you select (user-controlled or developer-controlled), the same blockchains are supported. The account type you select (externally owned account or smart contract account) does affect which blockchains are available.

The following tokens and standards are supported across blockchains:
  • EVM-compatible blockchains: native coin, ERC-20, ERC-721, and ERC-1155
  • Solana: native coin, SPL

​
Support for additional EVM blockchains

If you need a consistent wallet address across multiple EVM blockchains, you can use the wallet creation APIs. When you create a wallet address on one EVM blockchain, you can replicate and map the same address to another. This 1-to-1 mapping ensures that the wallet address remains consistent across the blockchains you use.

​
User-controlled wallets

Send a POST request to the /user/wallets endpoint and include the same X-User-Token in the header for authentication. In the request body, pass the new blockchains you want to associate with the wallets in the blockchains field. The existing EVM wallet address is used by default to create the wallets on the newly specified blockchains.

​
Developer-controlled wallets

Send a POST request to the /developer/wallets endpoint and include the same walletSetId that was used for previously created wallets on another EVM blockchain. To ensure consistency, provide the same count value as the number of wallets associated with the walletSetId. To obtain the count for a specific walletSetId, send a GET request to the /developer/wallets?walletSetId=<ID> endpoint and include walletSetId as a query parameter. If you only need signing capabilities such as sign transaction, sign typed data, or sign message on EVM blockchains, you can create wallets with a blockchains value of EVM or EVM-TESTNET and use those wallets to sign across different EVM-compatible blockchains. For more information, see Signing APIs.
For EVM-TESTNET wallets, you can sign transactions on the blockchains listed in Chain IDs for signing transactions. After you transition to mainnet, you can use your EVM wallet to sign transactions on any EVM-compatible blockchain.

​
Endpoint support by API category

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.
