Blockdaemon Builder Vault Integrates the Aleo Signing Curve Supporting Regulated Stablecoin Issuer Use Cases

Blockdaemon has implemented support for Aleo’s elliptic-curve-based signature requirements across Builder Vault and its SDKs, allowing regulated stablecoin issuers to support Aleo stablecoin use cases.

‍

Aleo signature support is available across Go, Mobile SDKs for iOS and Android, C, Java, NodeJS, and WASM, giving teams a consistent way to integrate Aleo-compatible signing through Builder Vault’s MPC-backed key management model.

How to use the Aleo Signing Curve Capability with Builder Vault?  

‍

The Blockdaemon Builder Vault SDKs provide access to the full suite of features supported by the Builder Vault TSM, including key creation, encryption, and signing using the created keys, as well as other administrative operations. 

‍

By using the SDK, Builder Vault allows full control over key infrastructure while reducing private key exposure. No full private key is generated or stored on a single device. Signing is performed through distributed key shares and configurable quorum approval.

‍

What is Builder Vault? 

‍

Blockdaemon Builder Vault is a self-hosted MPC key management and signing system for teams building wallets, custody platforms, payment applications, treasury tools, and other web3 services.

‍

Builder Vault works as a threshold security module, similar to a virtual HSM. Private keys are generated, stored, and used in a distributed way across MPC nodes, so no complete private key exists on any single device at any point in its lifecycle. Transactions are signed only when the required m-of-n approval threshold is met.

‍

Built on Blockdaemon’s patented Advanced MPC technology, Builder Vault gives institutions direct control over their key infrastructure while supporting flexible deployment across on-prem environments, public or private cloud, mobile devices, Docker, and secure enclaves such as AWS Nitro.

‍

Key capabilities include:

• Self-hosted control: Customers manage their own MPC infrastructure and key shares
• Threshold signing: Transactions require approval from m of n parties
• Flexible deployment: Run on-prem, in cloud, on mobile, in Docker, or in confidential computing environments
• Broad custody support: Supports regulated custody, self-custody, non-custodial models, WaaS, hot wallets, and cold wallets
• Protocol flexibility: Supports digital assets and protocols through universal threshold approval
• Low-latency signing: Designed for millisecond-level signing, encryption, and decryption
• Scale: Built to support millions of keys and wallets
