Chain support

Privy wallets support multiple blockchain ecosystems across three tiers. Each tier builds on the one before it. The higher the tier, the more Privy manages on your app’s behalf.

​

Capabilities by tier

Additional capabilities — policies, gas sponsorship, observability, wallet actions — vary independently by chain and are not part of the tier model. Some still require a minimum tier. See Additional capabilities.

​

Supported chains

​

Tier 3: Send transactions

Privy signs, broadcasts, and tracks transactions on these chains.

​

Tier 2: Sign transactions

Privy decodes and signs transactions.

​

Tier 1: Sign

Privy creates wallets and produces cryptographic signatures.

​

Specialized integrations

Some managed integrations do not map directly to the transaction lifecycle represented by the tier model.

​

Tier definitions

​

Tier 3: Send transactions

• Transaction construction — Privy constructs supported transactions from higher-level inputs and resolves chain-dependent fields when required.
• Managed submission — Privy signs, broadcasts, and tracks transactions, with transaction-status webhooks for lifecycle updates.

Tier 3 is the minimum threshold for anything that acts at broadcast time, such as fee payment, bundler routing, batching, and lifecycle tracking.

​

Tier 2: Sign transactions

• Transaction-aware signing — Privy decodes and validates the transaction before signing.

Tier 2 is the minimum threshold for transaction-level policy controls, because Privy must decode a transaction before it can evaluate conditions on the transaction’s contents.

​

Tier 1: Sign

Privy provides these capabilities across supported chains, through the signing interface that each chain exposes.

• Wallet creation — generate a new keypair for a supported curve (secp256k1, Ed25519, or Starknet)
• Private key export — retrieve the raw private key for non-custodial use or migration
• HD seed export — export the seed phrase for HD-derived wallets (Ethereum, Solana, Bitcoin Taproot, and Pearl only)
• Import — bring an existing private key or HD seed under Privy management, on a narrower set of chains than export
• Low-level signing — produce signatures appropriate to the wallet type

​

Additional capabilities

A capability that depends on Privy decoding, building, or submitting a transaction is unavailable below the tier that provides it. Reaching that tier does not by itself make the capability available.
