Self-custody user wallets with 2-of-3 MPC threshold signing, HSM and TEE key protection, and a policy engine applied before signing. Every transaction and approval is recorded in an audit log for operations and compliance teams.

The use case

Texavio provides self-custody wallets for exchange and brokerage users: users control their keys and Texavio never holds user funds. Keys use 2-of-3 MPC threshold signing and are protected with HSM and TEE. The policy engine applies spend and velocity limits, allowlists and jurisdiction rules before signing, and records each decision in an audit log. Wallets run on 30+ chains, including EVM networks, Solana and Bitcoin.

What the setup has to handle
  1. 01Holding customer keys adds regulatory and operational obligations
  2. 02A single hot-wallet key is a single point of failure
  3. 03Transactions settle on many chains, each with its own finality rules
  4. 04Operations teams need controls that do not expose customer keys
  5. 05Audit trails must serve internal compliance and external regulators
Platform capabilities

01

MPC / TSS Signing

2-of-3 threshold signing. No single key share can sign a transaction on its own.

02

HSM & TEE Key Protection

Key material is protected in hardware security modules and trusted execution environments.

03

Withdrawal Controls

Spend and velocity limits plus address allowlists and blocklists, checked before any withdrawal is signed.

04

Jurisdiction Rules

Policies restrict activity by jurisdiction. The policy engine applies them before signing, without access to customer keys.

05

Audit Logs

Every transaction, approval and policy decision is recorded in an audit log for compliance review and regulatory reporting.

06

30+ Chains

EVM networks, Solana, Bitcoin, Cosmos, Aptos, TON and Sui, served by one wallet infrastructure.
