Circle Wallets supports multiple blockchains. Account type support, token standards, and API coverage vary by blockchain.

​
Supported blockchains by account type

The following tables list supported blockchains and account types. Developer-controlled and user-controlled wallets support Externally Owned Accounts (EOA) and Smart Contract Accounts (SCA). Modular wallets use Modular Smart Contract Accounts (MSCA) only. For a full comparison, see Choose your wallet and account types.
For “Other EVM blockchains,” create wallets using the EVM or EVM-TESTNET chain code. Wallet addresses are consistent across all EVM-compatible blockchains. See Unified wallet addressing across EVM chains.

Blockchain-specific limitations

Every Wallets API endpoint is available on all supported blockchains, except for the blockchains listed below.
  • Aptos:
    • NFT lookup is not supported.
    • Balance queries return tokens in primary storage only. Tokens in secondary storage (AIP-21) are excluded.
    • Contract execution (developer-controlled, user-controlled) is limited to batch transfers. The abiFunctionSignature and contractAddress fields must use fixed values. The request body below shows the required values (entitySecretCiphertext is required for developer-controlled wallets only).
