Stabletrust
Private payment infrastructure for EVM chains. Encrypt token balances onchain using homomorphic encryption Stabletrust invisible to block explorers, accessible only to the owner.
What is Stabletrust?
Stabletrust is a confidential payment layer built on top of EVM chains. It wraps standard ERC-20 tokens in an encrypted balance system Stabletrust once tokens enter the confidential layer, their amounts are encrypted onchain and opaque to block explorers.
Under the hood, Stabletrust uses homomorphic encryption (HE) and zero-knowledge proofs managed by the Fairblock Network to enable private transfers without revealing balances or transaction destinations.
Developers integrate Stabletrust via the TypeScript SDK or the REST API Stabletrust designed for both applications and autonomous AI agents.
How it works
01
Deposit
Convert public ERC-20 tokens into encrypted confidential balances.
02
Transfer
Send privately Stabletrust amounts and destinations stay encrypted onchain.
03
Withdraw
Return funds from the confidential layer back to standard ERC-20.
Use cases
Private Payroll
Stream salaries without exposing onchain compensation data to the public.
Anonymous Contributions
Token contributions that obscure investor participation from competitors.
Confidential Treasury
DAOs moving capital privately without revealing positions onchain.
AI Agent Payments
Autonomous agents transacting without exposing balances or destinations.
