# Relayer Documentation

> Self-custodial stablecoin infrastructure — built for the operators of today and the agents of tomorrow

## Welcome to Relayer

**Relayer is the financial platform for stablecoin operators today, and the AI agents they'll deploy tomorrow.**

We give you a single self-custodial backend with three primitives:

* **Wallets** — passkey-signed, hardware-secured, multi-chain (EVM + Solana). Relayer never holds your private keys.
* **Fiat rails** — regulated on-ramp and off-ramp with local virtual accounts (CLABE/SPEI, ACH, more coming), KYB built in.
* **Programmable budgets** — every wallet can have spend limits, approval thresholds, and signing policies enforced before any transaction is processed.

The same primitives that let your **team** operate a compliant stablecoin business today let your **agents** operate it tomorrow — with budgets that cannot be bypassed, even by the LLM driving them.
