Stacks

Address derivation

Turnkey supports Stacks address derivation with ADDRESS_FORMAT_COMPRESSED and ADDRESS_FORMAT_UNCOMPRESSED address formats. Stacks addresses are derived from the secp256k1 curve, which Turnkey fully supports.

Transaction construction and signing

Turnkey supports Stacks transaction signing through the core signing capabilities. We have an example respository that demonstrates how to construct and sign Sui transactions:

examples/with-stacks: A sample script that demonstrates how to sign a Stacks transaction with Turnkey. Stacks uses the secp256k1 cryptographic curve for transaction signing, but there some specific data formatting that takes place for the signing process.

Key Features for Stacks

• secp256k1 signing: Turnkey fully supports secp256k1 curve used by Stacks
• Raw Transaction Signing: Sign any Stacks transaction format with Turnkey’s flexible signing API
• Integration Example: Our example repository provides a reference implementation

Benefits of Using Turnkey with Stacks

• Secure Key Management: Private keys never leave Turnkey’s secure infrastructure
• Developer Friendly: Integrate with existing Stacks development workflows
• Signing Policies: Apply custom policies to control transaction approvals
• Multi-address Support: Manage multiple Stacks addresses under a single organization
