Support tier definitions

​
Tier 3: Full functionality

Chains with Tier 3 support receive comprehensive capabilities, including:
  • Complete client-level support end-to-end
  • Full wallet functionality
  • Transaction building and submission
  • Native gas sponsorship
  • Advanced features like webhooks and policies

​
Tier 2: Wallet abstractions

Tier 2 support focuses on core wallet functionality:
  • Curve-level cryptographic signatures that can be used for transaction signing
  • Basic wallet functionality, including key export
  • Integration with chain-specific libraries
  • Chain address derivation
  • 0-index HD wallet creation and key derivation
  • Embedded wallets

​
Tier 1: Cryptographic signing

Tier 1 provides fundamental cryptographic capabilities:
  • Raw cryptographic signatures
  • Basic key management

​
Smart wallets, policies and more

Beyond this, Privy has advanced support for smart contract parsing as part of policies, native smart-contract wallet support and more. Please reach out if you need this for the chain your product leverages.

​
Upcoming support

We’re actively expanding our chain support capabilities. The following chains are expected to receive support this quarter:
  • Aptos / Move
Our roadmap prioritizes both expanding to new chains and enhancing support for existing chains by moving them to higher tiers.

​
Choosing the right integration

When building your application with Privy, consider the tier of support available for your target blockchain:
  • Tier 3 chains offer the most seamless experience with full native functionality
  • Tier 2 chains provide core transaction capabilities but may require chain-specific code
  • Tier 1 chains support basic signing operations and require more custom implementation
For questions about specific chain support or to request prioritization of particular chains, please contact the Privy team.
While all tiers allow for blockchain integration, lower tiers may require additional development effort to handle chain-specific operations.
