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.
